How To Compile TWRP Recovery For QVGA And Other Unsupported Devices
Guys a humble request don't spam this thread. If you face any error reply to this thread or PM me i will help and after you build it please don't post your bugs here this thread is only for compiling and not for resolving bugs in your build. I can only help with the errors you face during compilation because i faced a lot .
I thank XDA members cybojenix, kD as i got an idea of how to make guides from them
I would also thank Dees_troy for the sources.
I have worked hard in creating this guide so when you release your build please give proper credits .

Minimum Requirements:-
1. RAM:- 4GB
2. HDD Space:- More than 18GB required for CM7 source code (I am going to use CM7 for this guide as CM9 is not yet supported for many devices).
3. Processor:- Equal to Core 2 Duo or Anything above it.
4. Internet Speed:- Minimum of 2 Mbps as we will be downloading files of large size.
5. Patience:- A lots of it needed to get success

Ok Lets Start With Step 1:- Setting Up Your Computer For Development.
Getting Linux
Please note your PC/Laptop must satisfy the minimum requirements to continue. If it doesn't contact any person who is developing for your device to develop this.

After downloading install it in a Virtual Machine or dual boot it alongside another OS you are using now. If you are using a Virtual Machine make sure you allocate more than 50GB of HDD space.
So far so good now that you have Linux installed :victory: you can proceed to the next step of setting up which is followed in the second post.
Setting Up Your Laptop/PC For Development.

Installing Python-2.7.5:-
First and foremost is installing Python. For those who are wondering what Python is well here is the answer Python is a language like C,C++,Java which primarily centers around Linux.
1. Open Terminal by hitting Ctrl+Alt+T.
2. Type or copy paste these codes into terminal (I prefer typing though )
Code:
sudo apt-get install build-essential gcc
cd Downloads
wget http://www.python.org/ftp/python/2.7.5/Python-2.7.5.tgz
tar -xvzf Python-2.7.5.tgz
cd Python-2.7.5
./configure --prefix=/usr/local/python2.7
make
sudo make install
sudo ln -s /usr/local/python2.7/bin/python /usr/bin/python2.7
3. Python is now installed to make sure type this code in terminal
Code:
python
and it should produce an output like this
Code:
Python 2.7.2+ (default, Jul 20 2012, 22:15:08)
[GCC 4.6.1] on linux2
Type "help", "copyright", "credits" or " lincense" for more information.
>>>
4. If it shows something like that you are good to go.
5. Press Ctrl+D, close the terminal and proceed to install Java 6 JDK.
Installing Java 6 JDK:-
I have to thank cybojenix and kD for this part as it is theirs and i didn't write this part .
Click to expand...
Click to collapse
If you are using Ubuntu 12.04 follow these commands others skip this set of commands.
1. Download Java 6 JDK from here.
2. After Downloading copy that to the Downloads folder.
3. Open Terminal.
4. Type these commands one by one in the terminal
Code:
cd Downloads
chmod +x jdk-6u34-linux-x64.bin
sudo ./jdk-6u34-linux-x64.bin
sudo mv jdk1.6.0_34 /usr/lib/jvm/
sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.6.0_34/bin/java 1
sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.6.0_34/bin/javac 1
sudo update-alternatives --install /usr/bin/javaws javaws /usr/lib/jvm/jdk1.6.0_34/bin/javaws 1
sudo update-alternatives --config java
sudo update-alternatives --config javac
sudo update-alternatives --config javaws
If you are not using Ubuntu 12.04 follow these commands:-
1. Open terminal
2. Type these commands one by one in the Terminal.
Code:
sudo add-apt-repository ppa:ferramroberto/java
sudo apt-get update
sudo apt-get install sun-java6-jre sun-java6-bin sun-java6-jdk
If you had done those steps correctly then you must now have Java installed.
To check and make sure it is installed type this command in terminal.
Code:
java -version
and the output should be
Code:
java version "1.6.0_34"
Java(TM) SE Runtime Environment (build 1.6.0_34-b04)
Java HotSpot(TM) 64-Bit Server VM (build 20.9-b04, mixed mode)
If the output was some thing similar you are now ready to install GNU Make.
Close the Terminal and proceed.
Installing GNU Make 3.81
Note:- Any other version of make either lower or higher won't work for compiling TWRP.
Click to expand...
Click to collapse
1. Open Terminal
2. Type these codes in terminal.
Code:
wget -o make.tar.gz http://ftp.gnu.org/gnu/make/make-3.81.tar.gz
tar -xvzf make-3.81.tar.gz
cd make-3.81
./configure
sudo make install
3. That's it now you got make installed.
To check and make sure that Make is installed type this command in Terminal.
Code:
make -v
and it shoud give the output
Code:
GNU Make 3.81

If it was something smiliar to that you can close the terminal and proceed to the next step.
Ok now we got the big guns rolling it's now time for small guns without whom we can't compile yes I mean't the dependencies.
Open Terminal and apply these commands:-
Code:
sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev libc6-dev lib32ncurses5-dev ia32-libs x11proto-core-dev libx11-dev lib32readline5-dev lib32z-dev libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown libxml2-utils xsltproc gedit git schedtool
export USE_CCACHE=1
If you are using Ubuntu 10.10 apply this:-
Code:
sudo ln -s /usr/lib32/mesa/libGL.so.1 /usr/lib32/mesa/libGL.so
If you are using Ubuntu 11.04 apply this:-
Code:
sudo ln -s /usr/lib32/mesa/libGL.so.1 /usr/lib32/mesa/libGL.so
sudo apt-get install libx11-dev:i386
If you are using Ubuntu 12.04 apply this:-
Code:
sudo ln -s /usr/lib32/mesa/libGL.so.1 /usr/lib32/mesa/libGL.so
sudo apt-get install libx11-dev:i386
sudo apt-get install libncurses5-dev:i386 libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 zlib1g-dev:i386
sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so
Good now you will have dependencies installed.
It is now time for SDK and ADB which will be continued in the next post.
Installing SDK and ABD
Installing SDK:-
1. Download Android SDK from here.
2. Extract it to your home folder.
3. Rename the folder to sdk.
4. Open the Terminal and type these commands
Code:
cd sdk/tools
./android sdk
5. A window should popup and there will will be a list of Packages.
6. Install Android SDK Tools and Android SDK Platform-Tools.
Checking ADB:-
Since you installed Android SDK Tools and Android SDK Platform-Tools ADB must now be checked and configured.
1. Enable USB Debugging in your device and connect your phone to computer.
2. Now execute these commands in Terminal
Code:
cd sdk/platform-tools
./adb devices
It should give the output as
Code:
List of devices attached 0123456789ABCDEF device-name (Note the number-letter combination may vary)
If it does give like that skip Adding Permissions.
Or if it gives the output as
Code:
List of devices attached ????????????????? no permissions
Don't worry we have add permission to your device that's it.
Adding Permissions:-
1. Open Terminal
2. Execute this command.
Code:
sudo gedit /etc/udev/rules.d/51-android.rules
3. It should open text editor
4. Paste this line
Code:
SUBSYSTEM=="usb", ATTR{idVendor}=="xxxx", MODE="0666"
5. Replace Vendor ID with your Vendor id given in the list.
For e.g if your vendor is Acer you will replace "xxxx" with "0502"
Here is a list of Vendor ID's
Code:
Acer - 0502
ASUS - 0b05
Dell - 413c
Foxconn - 0489
Fujitsu - 04c5
Fujitsu Toshiba - 04c5
Garmin-Asus - 091e
Google - 18d1
Hisense - 109b
HTC - 0bb4
Huawei - 12d1
K-Touch - 24e3
KT Tech - 2116
Kyocera - 0482
Lenovo -17ef
LG - 1004
Motorola - 22b8
MTK - 0e8d
NEC - 0409
Nook - 2080
Nvidia - 0955
OTGV - 2257
Pantech - 10a9
Pegatron - 1d4d
Philips - 0471
PMC-Sierra - 04da
Qualcomm - 05c6
SK Telesys - 1f53
Samsung - 04e8
Sharp - 04dd
Sony - 054c
Sony Ericsson - 0fce
Teleepoch - 2340
Toshiba - 0930
ZTE - 19d2
6. Save and close the editor.
7. Execute this command in Terminal.
Code:
sudo gedit /etc/udev/rules.d/99-android.rules
8. Again paste this line
Code:
SUBSYSTEM=="usb", ATTR{idVendor}=="xxxx", MODE="0666"
Replace "xxxx" with Vendor ID.
9. Save it and close the file.
10. Execute these commands one by one in the Terminal
Code:
sudo chmod a+r /etc/udev/rules.d/99-android.rules
sudo chmod a+r /etc/udev/rules.d/51-android.rules
Now RESTART your Ubuntu and type these codes in the Terminal.
Code:
cd sdk
./adb devices
You must not get the output with ???????????????? no permission still if you get it please reply below I will help.
Now we need to edit .bashrc so that we can access adb from anywhere
Execute these codes in the Terminal.
Code:
cd
sudo gedit .bashrc
It should open text editor copy paste this line at the end.
Code:
export PATH=${PATH}:~/sdk/tools
export PATH=${PATH}:~/sdk/platform-tools
Save it and close it.
Now in terminal type adb devices it should give output List of devices attached.
That's it you got Ubuntu, Python, Java 6 JDK, GNU Make-3.81, SDK and ADB ready.
Now you are ready to start development go on to the next step to download source code.
Intializing Repo And Download Source Code
Step 2:- Initializing Repository And Downloading Source Code
Initializing Repository
First step is to download the Repo which is essential to download the source code.
1. Open Terminal
2. Execute these commands one by one in Terminal
Code:
mkdir ~/bin
PATH=~/bin:$PATH
sudo apt-get install curl
curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
chmod a+x ~/bin/repo
Downloading Source Code
After you have initialized the repo you are set to download the source code.
1. Open Terminal
2. Execute these commands one by one in Terminal
Code:
mkdir source
cd source
repo init -u git://github.com/Cyanogenmod/android.git -b gingerbread
sudo sysctl -w net.ipv4.tcp_window_scaling=0
repo sync -jx (Replace x with a number this number corresponds to number simultaneous download you want for e.g if you give 5 it will download 5 files at once so go on increase to whatever you like but be reasonable :D)
The Source Code is around 15GB - 17GB so have patience and more importantly HDD space.
Click to expand...
Click to collapse
.
The download will take hours if you are on slow connection like it will be a 2 days is 512kbps connection so if you are planning to develop please have a good internet connection with a reasonable fast speed. Every developer recommends more than 1Mbps and sometimes 4Mbps.
After downloading is finished go to source folder you must have many folders inside them. Also make a backup of the source folder just in case as we will modifying it so if something goes wrong you don't have to re-download it all again.
Go to the next step to start the actual development.
Modding Files And Stuff
Step 3:- Modding Files And Folders To Make Your Device Supportable.
First up is to compile a build of ClockworkMod.
Building ClockworkMod:-
1. Open Terminal
2. Type these commands one by one in Terminal
Code:
. build/envsetup.sh
lunch (it should show you list of devices select your device with their serial number select your device by typing the serial number)
make clean
make -j4 recoveryimage
If you didn't receive an error you are ready to compile TWRP for your device.
If you do receive and error reply to the post I will help you.
Modifying Files And Folder:-
The original Dees_Troy's build folder isn't gonna work as your device resolution doesn't support it. So I have patched the build folder with some extra libs added to prelink map and patched recovery folder with gui changes for smooth compilation.
If you have experience with using git you can clone the repo or you can download it directly from github.
Click to expand...
Click to collapse
If you are going to clone execute these commands in terminal. (Thanks to cybojenix for this so that there will no manual copying).
Code:
cd source
rm -rf build/
rm -rf bootable/recovery/
git clone git://github.com/chainhacker/TWRP_Build -b 2.3 build
git clone git://github.com/chainhacker/TWRP_Recovery -b 2.3 bootable/recovery
If you are going to download directly use the following link make sure you are downloading 2.3 branch and extract it.
Here is the link for the patched build folder------>TWRP_Build
Here is the link for the patched recovery folder------>TWRP_Recovery
After you have done downloading from the above two files.
Replace the contents of source/build folder with the patched one.
Similarly replace the contents of source/bootable/recovery folder with the patched one.
I have 240x320 resolution already in the patched ones but if your device is not 240x320 and also not supported by TWRP download a theme made by other members which has your device's resolution or create a theme. I didn't create the theme though I resized the images and made changes in ui.xml. If you are interested in theming follow the official TWRP theming guide in their website.
If you did find a theme or created it rename the theme folder to your device resolution folder for e.g. If your device resolution is 320x240 you would rename the folder as 320x240.
Copy the theme folder into source/bootable/recovery/gui/devices.
That's it finished the basic requirements next up is configuring BoardConfig.mk.
Editing BoardConfig.mk:-
1. Navigate to source/device/your_vendor/your_device.
your_vendor:- Vendor of your device e.g for me it is lge.
your_device:- Your device name.
Click to expand...
Click to collapse
2. Find BoardConfig.mk and open it in a text editor.
3. Come to the last and add these line
Code:
#twrp
DEVICE_RESOLUTION:= [I]your_device_resolution[/I] (e.g If your resolution is 240x320 type it)
RECOVERY_GRAPHICS_USE_LINELENGTH := true
2. Save it and close it.
Yay you have finished everything only thing left out is compiling which is carried out in the next post.
Psssst.......
After you have compiled your first successful build here are few other things that you could add to BoardConfig.mk
Note:- You can add this after finishing first successful build of recovery till then avoid these.
Click to expand...
Click to collapse
Code:
RECOVERY_SDCARD_ON_DATA := true -- this enables proper handling of /data/media on devices that have this folder for storage (most Honeycomb and devices that originally shipped with ICS like Galaxy Nexus)
BOARD_HAS_NO_REAL_SDCARD := true -- disables things like sdcard partitioning
TW_INCLUDE_DUMLOCK := true -- includes HTC Dumlock for devices that need it
TARGET_RECOVERY_GUI := true -- uses gui format instead of ui.xml
TARGET_RECOVERY_PIXEL_FORMAT := "RGB_565" -- to change the colour
TARGET_USE_CUSTOM_LUN_FILE_PATH :=/sys/devices/platform/usb_mass_storage/lun0/file
TW_CUSTOM_POWER_BUTTON := 107 -- to get a power button on the home screen of recovery
TW_EXTERNAL_STORAGE_PATH := "/sdcard" -- default external storage path
TW_EXTERNAL_STORAGE_MOUNT_POINT := "sdcard" -- default external mount point
TW_FLASH_FROM_STORAGE := true -- enables you to flash zips form the sdcard (You don't neeed o add this it is activated by default)
TW_HAS_DOWNLOAD_MODE := false -- to enable download or more precisely enabling usb mass storage
TW_HAS_NO_RECOVERY_PARTITION := true -- do this only if you device has no partion to recovery
TW_INCLUDE_CRYPTO := false
TW_INCLUDE_JB_CRYPTO := false
TW_NEVER_UNMOUNT_SYSTEM := true -- always keeps the system mounted
TW_NO_BATT_PERCENT := false -- shows battery percentage
TW_NO_REBOOT_BOOTLOADER := true --- disables rebooting into bootloader
TW_NO_USB_STORAGE := false -- disabled usb storage
TW_SDEXT_NO_EXT4 := false
Compiling Recovery
Step 4:- Compiling Recovery
Finally you have come to the final part of the guide which is compiling recovery.
1. Open Terminal.
2. Execute these commands in Terminal
Code:
. build/envsetup.sh
lunch (Again select your device)
make -j4 recoveryimage
.
That's it when it is finished grab recovery.img from:
out/target/product/your_product_name/recovery.img
Flash it in your device test it fix the bugs and release it.
Wait if you don't want flash and just see how it looks so that you can flash another recovery if it is not working do these
I am not resposible if your device gets bricked in fastboot mode but mostly it won't happen though
Click to expand...
Click to collapse
1. Copy the recovery.img to sdk/platform-tools
2. Boot your device into fastboot mode.
3. Open Terminal
4. Execute these commands one by one in Terminal
Code:
fastboot devices (wait for your device to show up int terminal)
fastboot boot recovery.img
You can test out all the features except flash zip, backup and restore.
Victory :victory: you have successfully compiled TWRP recovery for your device go ahead have fun and enjoy.

Nope it won't make any difference it is just the same even if your device is ARMv6 or ARMv7. Make sure your device is supported by CM

So that's me again :laugh: Wanted to compile TWRP 2.6.0.0 for cm10.1 so I have set up everything so far but get an error when I try to compile
build/core/base_rules.mk:130: *** external/fuse/lib: MODULE.TARGET.STATIC_LIBRARIES.libfuse already defined by bootable/recovery/fuse.
Click to expand...
Click to collapse
Seems to be really stupid, so far I understand is the libfuse defined twice in recovery and base_rules.mk so think (thought ) it's an easy part - just to remove this libfuse from one of them... But I can't find something with "libfuse", "static libraries" or anything like that in base_rules.mk

I have never tried compiling 2.6.0.0 because Dees_Troy is evaluating my theme for my device such that it gets official support so if you are ready to use CM7 and TWRP 2.3.3.0 you can follow my guide and i can help you with the errors but any other version please ask Dees_Troy for the solution.

Hi, Chain Hacker.
Does it matter how to write address after "git://"?
I mean this:
Code:
[B]repo init -u git://github.com/Cyanogenmod/android.git -b gingerbread[/B]
Should it be like this:
Code:
[B]repo init -u git://github.com/Cyanogen[COLOR="Red"]M[/COLOR]od/android.git -b gingerbread[/B]
By the way, it's a very good manual for those who are just starting to understand how to compile

No i doesnt matter at all the only thing that is case sensitive are the words after cyanogenmod as they must be written as it is so it is your wish whether you are gonna write Cyanogenmod or CyanogenMod and by the way thanks for the complement

TWRP Recovery size...
Hi again...
I've managed to compile a TWRP-Recovery 2.6.0.1 based on CM9 for my Huawei Ascend Y101 (8186).
But I had to change recovery partition size in BoardConfig.mk (originally it was BOARD_RECOVERYIMAGE_PARTITION_SIZE := 0x00500000, I changed it to 0x00600000), because without these changes it wasn't possible to build a recovery.img ("recovery.img is too large... etc.")
When I flashed it on my device, the TWRP recovery started and worked perfectly, but I wasn't able to boot my device. But it's not a problem for me, I understand why it wasn't able to boot very good.
The question is the following: is it possible to decrease somehow the source files' sizes of TWRP recovery (maybe images, don't know...) in order to compile the recovery.img that would be less than 4.85 MB (actually it's size is 5*095*424, it's more than my recovery partition....... )
By the way, the size of a CWM-recovery (cm9) that I've compiled is 4*489*216, so it fits like a glove :good: and works fine...
Thanks in advance. I understand that you compiled a TWPR recovery based on CM7, but I don't see much differences...

The difference is no on the source dude so relax. You have to modify your kernel and change the compression method to lzma. Contact Dees_Troy for this because i dont know how to change it. You can chat with him through IRC.

I started this thread because my pre-paid phone is not a supported device.
I have to start this over from scratch, so no need to dwell in the past. The reason I started learning this stuff was to help others. I don't even use custom roms in my phone. I have always liked computers, and anything to do with electronics. I don't care for this N00Bz word. I don't care for people that look down on another human being for anything. God above made us all differently for a reason. Society made sellers and buyers, translated to the Android community as builders and users.. My old lady thinks ROOTING is something you do in the garden.. My new project has nothing to do with Cyanogenmod,AOKP, or JellyBeer. I like to do things that no one has done yet. That is why I am not going to reveal my new Source code. Seems like everytime I come up with an idea somebody else gets "motivated" to do it. lol To be honest I will be working on two seldom done roms, i'm repo sync'n the first one right now. Also, during my stay at XDA- i will make a very detailed tutorial on building from Source. Starting with
1. dual and tri booting your PC, for the Windows lovers. (u need Linux 2 build)
2. Learning to use "Google" , this is your new best friend, It never gets tired of your questions, it never runs out of answers, and open 24 hours a day...
3. Learn basic linux commands ....cd, su, apt-get, etc
4. Setting up your build by yourself
5. Setting up a pre-made build box (see step 1)
6. Learn to use Github
7. Use your newly acquired knowledge to "git" your Sources
8. Build a device tree
9. Build a kernel
10. Put together a script to pull Prop files
11. Building
12. Beating your head on the desk when you can't figure out why it wont build, boot , and why you have so many "bugz"
I AM NOT A DEVELOPER
But when i finish this tutorial, i will be.
this tutorial will not cover anything to do with "cooking" a rom, that is cheating...lol
Now I'm going to try my luck at these new $ROM$.
Thank you for visiting and God bless you
"MORE TO FOLLOW"
In the Beginning ,there was DARKNESS and cheap phones
STEP 1
Windows 7 and Ubuntu,BBQ, or Mint,etc,Build boxes or from live CD. Despite their opposing missions, can get along like best pals on a single computer. Here's how to set up a dual boot or tri boot system that lets you enjoy the best of both worlds in perfect harmony. I know this works because it is how my system at home and on my laptop are setup.
HINT: Linux has around 100 viruses, Windows , it can't be counted. In linux it is harder to get viruses on a PC. Also, Windows viruses don't carry over to your Linux build OS.
Seen in this comparison article
"The expression is intended to suggest that proprietary software is more secure by virtue of its closed nature. If hackers can't see the code, then it's harder for them to create exploits for it--or so the thinking goes.
Unfortunately for Windows users, that's just not true--as evidenced by the never-ending parade of patches coming out of Redmond. In fact, one of Linux's many advantages over Windows is that it is more secure--much more. For small businesses and other organizations without a dedicated staff of security experts, that benefit can be particularly critical."

1. Make sure you have CD's or USB's with your Distro's on them. I use image burn. If it's Windows, PAY FOR IT!!! if it's Linux, IT'S FREE!!!
2. You are going to need extra space on your hard drive, or PG suggested you can use an extra hard drive.
a. Each repo is going to use up 30 GB
b. Your build tools maybe 5 GB
c. 300 mb for the boot
d. 5-10 GB for the SWAP
e. I use a 1TB for a tri-boot ,500 GB for Windows 7- 250 GB for each of my Linux distros
f. RAM,RAM,RAM,RAM and then some more RAM-- u can thank me later.
g. If you don't have RAM, like on my laptop, I just hooked it to my Internet connection, and let it pull Source while I was sleeping.
3. I like to start fresh--Make a backup, Then I use "KILLDISK" ,it is free and it will write zero's on your hard drive. "Warp, Why do u do that?"
I don't like viruses.
4. Use your Recovery partition or your Windows XP/VISTA/7/8 disk to install the OS.
5. Many hours later, boot into Windows, and hit Start..type diskmgmt.msc
6. If you haven't partitioned a hard drive ,Google it, and learn, this is not a game.
7. Dual boot = 2 primary partitions Tri boot = 3 primary partitions.
Logical is OK for Linux, but dynamic is no good.
8. Pop that fresh copy of your distro in
9. If you are new to Linux "Google it"
10. If you press install alongside windows, it will search out the empty partition and install
11. I don't like GRUB2.
12 Get the non-commercial version of "EasyBCD for Windows, install it, u will be needing it.
13. This is also a free app Google "use easy BCD for dual boot"
14. The only other step needed on the tri boot setup is logging into the first Linux distro u install, open terminal and execute update-grub2 . after everything else is done...
15. If you opted for the "Build Box, skip the setting up build step....
There is also another method to installing Linux on a Laptop, or a stubborn PC with Graphics issues and that is with the "Alternate Ubuntu installer"
I have only got this to work on 12.04 lots with recovery failsafex mode
REMOVE
SYSTEM RESERVED:
THIS CAN MESS UP YOUR PC:
I'M ONLY ADDING THIS FOR ADVANCED USERS:
ALL THE STEPS ARE HERE AT THIS LINK, BUT I USED WHATS IN THE CODE BOX AND IT WORKED FOR ME.
http://www.terabyteunlimited.com/kb/article.php?id=409
Code:
Open Disk management ,
give SYSTEM a drive letter of e:
Run CMD as Admin
reg unload HKLM\BCD00000000 (if you get an ERROR: bla bla bla) then this may already be removed)
robocopy e:\ c:\ bootmgr
robocopy e:\Boot C:\Boot /s
dir c:\ /ah
If the bootmgr file and the Boot folder show up in the list, the procedure was successful.
bcdedit /store c:\boot\bcd /set {bootmgr} device partition=C:
bcdedit /store c:\boot\bcd /set {memdiag} device partition=C:
Close the Command Prompt window.
Return to Disk Management
Right-click on the Windows partition and select Mark Partition as Active
IF YOU HAVE TO ASK "WHY" I DID THIS ...DON'T DO IT (see number 7.) also easyBCD can do this process as well
Then came GOOGLE!
STEP 2
This is a SIMPLE STEP...
WWW.GOOGLE.COM
Not www.goggle.com which is a real site, made by Hack3rz. it will mess your PC up.
This step is not limited to one search engine, Google is just my preferred one, because it links in UTUBE in search results and i like it.
Here is a list of other search engines.

I got this list from using "Google"
1. you need to know how many MB in a GB , Google it =1024
2. You need a copy of a missing file ...
3. Anything you aren't sure of.....
4. If you can't find it then go to XDA, Android Forums, unleashedprepaids.com, etc and Search it. Chances are somebody has had the same problem as you.. DONE STEP 2
No, You mean I have to learn something to make a $ROM$

MOST OF THESE YOU WON'T USE...
All by myself, I did it!!
STEP 4
This next step is not easy, it is time-consuming. So if you chose a "Build Box" I understand..
Lucky for you, i have already found everything for you , So split your screen .
On one side a fresh terminal, on the other side my tutorial, and copy/paste from the beginning of part B).
HINT: When adding any file with apt-get. Watch for anything being removed and anything being added. Also copy any SUGGESTED programs to a text- editor ,research them and add them if you like..
Also when adding things with the command--- $ sudo apt-get install , numerous items can be added behind the command, but i recommend doing it one by one.
This is because of obsoleted software or missing software errors.
This is only going to be a basic list: Seperated in two parts, by A)what you need and B)how to get it.
A) TOOLS OF THE TRADE:
1. Compile Dependencies (libs)
2. Python 2.7.3 (3.2 and 3.3 opt.)
3. GNU MAKE (3.81 or 3.82)
4. Java JDK 6.xx ( not 7)
5. Android SDK
6. ADB & Fastboot
7. USB Configs
8. Repo command
9. Add everything to the PATH in ./bashrc
When you see this symbol "$", it means you are in terminal, but not as "ROOT"
Although if you see this symbol # , you are the "ROOT" user .
Your directory name will be in Red as well.
"But Warp, I don't know how to ROOT my Linux Box"
You don't say...
terminal: $ sudo passwd root
this will then open up Unix for you
add some passwords /confirm password /REMEMBER YOUR PASSWORD!!!
My password is ********** lol.
But Warp, I'm a brave "new user" I want "ROOT" access to file manager..
For Ubuntu
Terminal: $ gksudo nautilus
enter password-- DONE
For Mint (cinnamon)
Terminal: $ gksudo nemo
enter password-- DONE
For Mint (Mate)
Terminal: $ gksudo caja
enter password-- DONE!!!

After you do all this, may be a good idea to add $ sudo apt-get upgrade
2. I don't get this step. Python is already on there, and if it ain't when you input "sudo apt-get install python" it will be...
3. Gnu Make , Your suppose to get this inside of build-essential , I like to know i got the newest one ,so i do it like this.
go to http://ftp.gnu.org/gnu/make/
Download GNU MAKE 3.82
Open up file manager
go to download folder
cut file
go to home directory
paste
extract
close file manager
Open Terminal:
$ cd <name of gnu make folder(exact)>
then it will look something like this
gnu make $
$ ./configure
$ make
# make install
# make clean...DONE
4. Get rid of pre-installed "JAVA"
$ sudo apt-get purge openjdk-\* icedtea-\* icedtea6-\*
Add new Oracle JAVA 6
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java6-installer
If you want to check the version after it is done
Terminal: $java -version
http://developer.android.com/sdk/index.html#download
5.Terminal: $ wget http://dl.google.com/android/android-sdk_r22-linux.tgz
When that finishes downloading
Terminal: $ tar -xvzf android-sdk_r22-linux.tgz
After extracting the package, run the command below to change into the tools directory.
cd ~/android-sdk-linux/tools
Finally, run the commands below to begin the installation.
./android update sdk
./android
"wget" is the same thing as "curl"
6. This may seem like a pointless step.
Warp, I already have ADB & Fastboot when I installed SDK, but do you have the 4.2.2 update ??
Just to make sure..
Terminal: $ sudo apt-get install android-tools-adb android-tools-fastboot
7. Create a folder in Home dir "51-android.rules" .
Now open a terminal and input: $ gksudo gedit /etc/udev/rules.d/51-android.rules
When another screen pops up copy and paste this inside--
Code:
#Garmin-Asus
SUBSYSTEM=="usb", ATTR{idVendor}=="091E", MODE="0666"
#Google

Save & Close text-editor.
Now fire up another terminal
To set proper permisisons: (Provide read permission to all users, in addition to whatever other permissions are pre-set)
input:
Terminal: $ sudo chmod a+r /etc/udev/rules.d/51-android.rules
8. Terminal: $ mkdir -p ~/bin
$ curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
Terminal: $ chmod a+x ~/bin/repo
Terminal: $ export PATH=${PATH}:~/bin
9. You can make this change to the path permanent for all future Terminal sessions:
Terminal: gedit ~/.bashrc
add export PATH=${PATH}:~/bin, on its own line, then save the file.
If you ever have problems with repo.. try this
- Make sure you have a bin/ directory in your home directory and that it is included in your path: (Very Important)
$ PATH=~/bin:$PATH
- Next,
$ curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod +x ~/bin/repo
I don't wanna do it
STEP 5
This step was included , for no particular reason. If you chose a build box, and you made it past step 1 without using it, you did something wrong. Go back to step 1
But I might as well include a few sources for build boxes
BBQLinux http://sourceforge.net/projects/bbqlinux/files/
SuperR's ubuntu or mint buildbox http://unleashedprepaids.com/thread-8191-post-61357.html
h311sdr0id's--h311's kitchen http://forum.xda-developers.com/showthread.php?t=2152398
How did he do that???
STEP 6
GitHub is a web-based hosting service for software development projects that use the Git revision control system. GitHub offers both paid plans for private repositories, and free accounts for open source projects.
If you are a person that wants to "build" and become more than just a "user", then your next stop is at "Github"...
Your old buddy "Google" can get you there pretty fast.
The site provides social networking functionality such as feeds, followers and the network graph to display how developers work on their versions of a repository.
According to the terms of service,if an account's bandwidth usage significantly exceeds the average of other GitHub customers, the account's file hosting service may be immediately disabled or throttled until bandwidth consumption is reduced. In addition, while there is no hard limit, the guideline for the maximum size of a repository is one gigabyte.
GitHub also has their standard GUI application available for download (Windows, Mac, Linux) directly from the service's website.
Ever wonder, "How did this Dev get this unsupported device to boot the latest rom?" Chances are, the way they did it will be inputted in Github.
Pay attention to the device names and models, This is important, because like I said every device is different... Everyday lately, I spend an hour or two looking through Github. Not just at my device, but at other models, other kernels, other Solutions...
Now I'm not saying go there, Find a boardconfig you like, cut/paste it into your device tree, but you may find some answers to problems.

"GIT" it!!!
STEP 7
"GOT RAM" This is when it will come in handy. EDIT: If you like to multi-task. "message for the anal thread readers"
Open up file manager, HOME directory ,make new folder, name it "android" (easy way to do it)
Open "android" folder, make new folder, name it "system"
Close file manager
or
Fire up a terminal
$ mkdir android
$ cd android
$ mkdir system
To get your Source, all you need are three things.
1. Git
2. Curl
3. Repo command
Whether you used a "build box" or set it up yourself , you have everything, but to pull Source, that's all it uses...
How to Initialize the source repository
Code:
REPOSITORY'S OF FAMOUS ROMS (Select One)
AOSP
repo init -u https://android.googlesource.com/platform/manifest -b android-4.2.2_r1.2
PAC-Man :
Code:
repo init -u git://github.com/PAC-man/android.git -b cm-10.1
repo init -u git://github.com/PAC-man/android.git -b cm-10.2
CM 10.1 :
Code:
repo init -u git://github.com/CyanogenMod/android.git -b cm-10.1
CM10 :
Code:
repo init -u git://github.com/CyanogenMod/android.git -b jellybean
BeerGang :
Code:
repo init -u git://github.com/BeerGang/android.git -b cm-10.1
Aokp
For 4.2
repo init -u https://github.com/AOKP/platform_manifest.git -b jb-mr1
For 4.1
repo init -u https://github.com/AOKP/platform_manifest.git -b jb
MIUI
repo init -u git://github.com/MiCode/patchrom.git -b ics
Paranoid android
repo init -u git://github.com/ParanoidAndroid/android.git -b jellybean
slim bean
repo init -u git://github.com/SlimRoms/platform_manifest.git -b jb4.2
teambaked
repo init -u https://github.com/TeamBAKED/platform_manifest.git -b jb
(I got this from another guide)
There are other codes out there, but these are main-stream.
So, what you want to do is , open a Terminal
cd = change directory
So you will
$ cd android
$ cd system
$ repo init -u git://github.com/PAC-man/android.git -b cm-10.1
At this point half your terminal or all your terminal will fill with text.
Two ways this will play out
1. it will let you register with name and email
2. it will give you on-screen codes to config it to your name and email
If you want the "Goodies" DO AS IT TELLS YOU
Now after you got that taken care of,
$ repo sync
Learn this code, remember this code, love this code.
it not only pulls the Source to your PC, but it also updates it every time you input it.
So, say Pacman adds a bluetooth update, BAM, that's how you get it.
It depends on your PC specs, to whether how long downloading your Source will take.
PG gets it quick, i get it slow, but we both get it...
For the next month or 4ever, this is where your "repo" will live..
Learn this folder, Open every folder, learn what's in there.
DO NOT ALTER, DO NOT DELETE, DO NOT REMOVE ANYTHING YET!!!
This tree has broken branches
STEP 8
Creating a basic new device tree
First step to this is to search Github for a device tree for your specific device.
This is where I got lucky.
PG and his associates lol, had already put together a working device tree for our device.
Chances are ,if your device didn't just hit the stores this week, somebody may have started work on a device tree for it.
Although if you do not have anything to start with, You must first open your device folder in the "repo" you "sync'd" to your PC, look at the supported devices
This will be a tool only for reference.
As I open my folder I notice the following
Code:
1. A "bluetooth" folder, with a config file
2. An "include" folder
3. An "overlay" folder
4. A "prebuilts" folder
5. A "recovery" folder
6. A "releasetools" folder
7. AndroidBoard.mk
8. AndroidProducts.mk
9. Boardconfig.mk
10. CM.mk
11. device_warp2.mk
12. extract-files.sh (this is to pull prop blobs)
13. full_warp2.mk
14. Proprietary-files.txt( a list of the prop files you will pull from your stock phone)
15. recovery.fstab
16. setup-makefiles.sh
17. system.prop
18. USBcontroller.cpp
With this group of files, i was able to get a built, but not bootable copy of Jellybeer 10.1.
Now some devices have less and some have alot more files in the device folder.
If you are really serious about becoming a developer, you have to search out others on Github, forums, etc
This step will take teamwork.
Below are two explanations of the files that go into making a device tree...
The directions below describe how to configure make files for new mobile devices and products.
Code:
Create a company directory in //device/partner.
mkdir device/partner/<company_name>
Create a products directory beneath the company directory you created in step 1.
mkdir device/partner/<company_name>/products/
Create a product-specific make file, called device/partner/<company_name>/products/<first_product_name>.mk, that includes the following code:
$(call inherit-product, target/product/generic.mk)
#
# Overrides
PRODUCT_NAME := <first_product_name>
PRODUCT_DEVICE := <board_name>
In the products directory, create an AndroidProducts.mk file that point to (and is responsible for finding) the individual product make files.
#
# This file should set PRODUCT_MAKEFILES to a list of product makefiles
# to expose to the build system. LOCAL_DIR will already be set to
# the directory containing this file.
#
# This file may not rely on the value of any variable other than
# LOCAL_DIR; do not use any conditionals, and do not look up the
# value of any variable that isn't set in this file or in a file that
# it includes.
#
PRODUCT_MAKEFILES := \
$(LOCAL_DIR)/first_product_name.mk \
Create a board-specific directory beneath your company directory that matches the PRODUCT_DEVICE variable <board_name> referenced in the product-specific make file above. This will include a make file that gets accessed by any product using this board.
mkdir device/partner/<company_name>/<board_name>
Create a product_config.mk file in the directory created in the previous step (device/partner/<company_name>/<board_name>). If this directory does not include a product_config.mk file, the build will fail.
# These definitions override the defaults in config/config.make for <board_name>
#
# TARGET_NO_BOOTLOADER := false
# TARGET_HARDWARE_3D := false
#
TARGET_USE_GENERIC_AUDIO := true
If you wish to modify system properties, create a system.prop file in your <board_name> directory(device/partner/<company_name>/<board_name>).
# system.prop for
# This overrides settings in the products/generic/system.prop file
#
# rild.libpath=/system/lib/libreference-ril.so
# rild.libargs=-d /dev/ttyS0
Add a pointer to <second_product_name>.mk within products/AndroidProducts.mk.
PRODUCT_MAKEFILES := \
$(LOCAL_DIR)/first_product_name.mk \
$(LOCAL_DIR)/second_product_name.mk
device/partner/<company_name>/<board_name> must include an Android.mk file with at least the following code:
# make file for new hardware from
#
LOCAL_PATH := $(call my-dir)
#
# this is here to use the pre-built kernel
ifeq ($(TARGET_PREBUILT_KERNEL),)
TARGET_PREBUILT_KERNEL := $(LOCAL_PATH)/kernel
endif
#
file := $(INSTALLED_KERNEL_TARGET)
ALL_PREBUILT += $(file)
$(file): $(TARGET_PREBUILT_KERNEL) | $(ACP)
$(transform-prebuilt-to-target)
#
# no boot loader, so we don't need any of that stuff..
#
LOCAL_PATH := partner/<company_name>/<board_name>
#
include $(CLEAR_VARS)
#
# include more board specific stuff here? Such as Audio parameters.
#
To create a second product for the same board, create a second product-specific make file called device/partner/company_name/products/<second_product_name>.mk that includes:
$(call inherit-product, partner/google/products/generic.mk)
#
# Overrides
PRODUCT_NAME := <second_product_name>
PRODUCT_DEVICE := <board_name>
By now, you should have two new products, called <first_product_name> and <second_product_name> associated with <company_name>. To verify that a product is properly configured (<first_product_name>, for example), execute the following:
cd device
. ./envsetup.sh
partner_setup <first_product_name>
make PRODUCT-<first_product_name>-user
You should find new build binaries located in device/out/target/product/<board_name>.
New Product File Tree
The file tree below illustrates what your own system should look like after completing the steps above.
<company_name>
<board_name>
Android.mk
product_config.mk
system.prop
products
AndroidProducts.mk
<first_product_name>.mk
<second_product_name>.mk
Part 2
Right... So you want to build your own device tree, read on.
Disclaimer: this is by no means complete, and there will be omissions as have explained all this top of my head and copied pasted certain bits that I have here on my own device tree.
The device tree, for example, /device/lg/gt540would consist of the following make files:
Code:
Android.mk - this will tell the build system to include and to build sources specifically for your device. See below, for an example. This is dependant on the device and hardware, you could have libsensors, liblights, libcamera subdirectories under the example device tree, i.e. /device/lg/gt540/libsensors, /device/lg/gt540/liblights, /device/lg/gt540/libcamera etc.
AndroidBoard.mk - this is for the kernel, the build system uses that to drop the kernel image in place (more about this in a few minutes)
AndroidProducts.mk - specifies the appropriate device's make file, to use for building. i.e. /device/lg/gt540/device_gt540.mk, this is specific also.
device_xxxxx.mk - specifies the properties and extras to copy over into the final output, in this case, it could be for example, device_gt540.mk
BoardConfig.mk - This is the meat of it all, this is where compiler conditional flags are set, partition layouts, boot addresses, ramdisk size, and so on.
Lets peek into each of those to give a glance as to where it all fits in.
Code:
Android.mk:
ifeq ($(TARGET_BOOTLOADER_BOARD_NAME),xxxxx)
include $(call all-named-subdir-makefiles, recovery libsensors liblights libcamera ....)
endif
This is how the build will use that to build recovery, sensors, lights and camera (of course there will be more), its saying 'Yo Builder, go into each of the directories specified, and build the respective sources plskthxbai'
AndroidBoard.mk:
LOCAL_PATH := device/lg/gt540/
#
# Boot files
#
TARGET_PREBUILT_KERNEL := $(LOCAL_PATH)/kernel
file := $(INSTALLED_KERNEL_TARGET)
ALL_PREBUILT += $(file)
$(file): $(TARGET_PREBUILT_KERNEL) | $(ACP)
$(transform-prebuilt-to-target)
Now this, is telling the build system, to be able to drop this kernel into the out/target/product/lg/gt540 (notice the correlation with the device tree directory?)
AndroidProducts.mk:
PRODUCT_MAKEFILES := \
$(LOCAL_DIR)/device_gt540.mk
Its telling the build as in 'Yo Builder, read that device make file please and process it upon completion of build.'
*device_xxxxx.mk: (for this example, device_gt540.mk) *
PRODUCT_NAME := lg_gt540
PRODUCT_DEVICE := gt540
PRODUCT_MODEL := LG GT 540
PRODUCT_COPY_FILES += \
... specific ...
PRODUCT_PROPERTY_OVERRIDES := \
ro.com.android.dateformat=dd-MM-yyyy \
... more stuff ...
This is where all the specifics for the device such as drivers, proprietary libraries, supporting scripts specifically for the device, gets copied over to out/target/product/lg/gt540/system/ in this case. Notice how the overrides for the properties, these end up in the build.prop found in the root of the /system of the Android ROM.
BoardConfig.mk:
LOCAL_PATH:= $(call my-dir)
TARGET_NO_BOOTLOADER := true
TARGET_PREBUILT_KERNEL := device/lg/gt540/kernel
TARGET_PREBUILT_RECOVERY_KERNEL := device/lg/gt540/recovery_kernel
# This will vary from device!
TARGET_BOARD_PLATFORM := msm7k
TARGET_ARCH_VARIANT := armv6-vfp
TARGET_CPU_ABI := armeabi
TARGET_CPU_ABI := armeabi-v6l
TARGET_CPU_ABI2 := armeabi
# OpenGL drivers config file path
BOARD_EGL_CFG := device/lg/gt540/egl.cfg
# Dependant, not to be taken literally!
BOARD_GLOBAL_CFLAGS += -DHAVE_FM_RADIO
# Dependant, not to be taken literally!
BOARD_KERNEL_BASE := 0x02600000
# this will be device specific, and by doing cat /proc/mtd will give you the correct sizes
BOARD_BOOTIMAGE_PARTITION_SIZE := 0x00480000
BOARD_RECOVERYIMAGE_PARTITION_SIZE := 0x00480000
BOARD_SYSTEMIMAGE_PARTITION_SIZE := 0x0cf80000
BOARD_USERDATAIMAGE_PARTITION_SIZE := 0x0d020000
BOARD_FLASH_BLOCK_SIZE := 131072
That is an excerpt, notice how we specify kernel's base address, this is how the boot.img gets generated after compilation is done and yet again, gets dropped into out/target/product/lg/gt540/boot.img. Also, more importantly, we're telling the build system to use the target platform for cross-compiling the sources (*TARGET_BOARD_PLATFORM*/*TARGET_CPU_ABI*) There will be more information in there such as conditional flags to pass to the compiler, for an example. we specified the directive HAVE_FM_RADIO to tell it, when it comes to handling the source for the FM radio system, to conditionally compile parts of the source. Again, this is hardware specific and mileage will vary, also this applies to the address for boot. In a nutshell, this is saying 'Yo Builder, read the damn variables and remember them and apply them when cross-compiling those source files!'
Now that the internals of each of those Android build make-files are shown.
Now, onto the vendor/ part of it, in AOSP, simply, once again, correlation and corresponds with the device/ tree, as in continuing with this example, vendor/lg/gt540/ which gets picked up by the lunch. There's more make files in there but the general consensus is there's a directory called proprietary which contains the proprietary libs (due to close-source etc) that gets copied over. The copying over of the libraries gets specified in the file device-vendor-blobs.mk, in this case, gt540-vendor-blobs.mk.
When the magic happens by doing the following:
. build/envsetup.sh
This is reading in the entire entries found in each of the device/ subdirectories and "remembers them", so the build system knows what type of target is used etc.
When the . lunch gets invoked, a menu appears prompting to pick the device that is required to build. Now the last and final step to do the build...
make -j5 > buildlog.log 2>&1
I run multitail on another terminal and monitor the buildlog.log file to check and make sure its building.
This last step will depend on how many cores you have (n cores + 1 as a rule) and it takes a while to build, GB build takes 40mins on my laptop running Arch Linux 64bit, ICS build takes about 2hrs 30 mins. So mileage will vary on what type of horsepower your machine has.
When the build is done, a little bell goes off and at the bottom of the said log file, I see this:
Combining NOTICE files: out/target/product/xxxxx/obj/NOTICE.html
Target system fs image: out/target/product/xxxxx/obj/PACKAGING/systemimage_intermediates/system.img
Install system fs image: out/target/product/xxxxx/system.img
out/target/product/xxxx/system.img+ total size is 108776448
As matter of interest JBQ (Jean Baptiste Queru - the 'boss' for managing/distributing the source from Google), his build step is this...
Code:
Extra code to use the ICS Repository
Now enter the following to initialize the repository:
cd ~/android/system/
repo init -u git://github.com/CyanogenMod/android.git -b ics
Extra codes to use the JB Repository
Now enter the following to initialize the repository:
cd ~/android/system/
repo init -u git://github.com/CyanogenMod/android.git -b jellybean
This is not everything, because a device tree for every device is different, To start from scratch will take alot of time.
You will add, then remove, and then add again.
ASSEMBLE A TEAM...THIS IS A ADVANCED STEP
The president has spoken
STEP 9
Building a kernel.
You're in deep waters once again.
To explain the kernel, I would say he is like the president of your phone.
He tells everyone what to do, and when to do it, and how to do it.
Kernel
The kernel is the core of an operating system. It functions on a low level (kernelspace) interacting between the hardware of the machine and the programs which use the hardware to run. To make efficient use of the CPU, the kernel uses a scheduler to arbitrate which tasks take priority at any given moment, creating the illusion of many tasks being executed simultaneously.
(From an article about Arch Linux)
"Do you like LAG?"
Well if you answered "no"
Then you better build a good kernel.
I entered "building a kernel for android" and i got a long list of tutorials on this.
So, if my section on kernels isn't enough, Google has more.
"git clone" is the code prefix if you luck out and find a kernel source on github.
first you would
$ cd android
$ cd system
$ cd kernel
$ mkdir <name of company>
$ cd <name of company>
$ git clone bla bla bla bla bla lol
But for the purpose of this step, you did not find a kernel source...
So, if you did step 8, or you found a device repo on Github, then you know alot more about your device now, specifically the hardware that pushes your device..
This table lists the name and locations of SOME kernel sources and binaries
Device / Binary location / Source location / Build configuration
manta / device/samsung/manta/kernel / kernel/exynos / manta_defconfig
mako / device/lge/mako-kernel/kernel / kernel/msm / mako_defconfig
grouper / device/asus/grouper/kernel / kernel/tegra / tegra3_android_defconfig
tilapia / device/asus/grouper/kernel / kernel/tegra / tegra3_android_defconfig
maguro / device/samsung/tuna/kernel / kernel/omap / tuna_defconfig
toro / device/samsung/tuna/kernel / kernel/omap / tuna_defconfig
panda / device/ti/panda/kernel / kernel/omap / panda_defconfig
stingray /device/moto/wingray/kernel / kernel/tegra / stingray_defconfig
wingray / device/moto/wingray/kernel / kernel/tegra / stingray_defconfig
crespo /device/samsung/crespo/kernel / kernel/samsung / herring_defconfig
crespo4g / device/samsung/crespo/kernel / kernel/samsung / herring_defconfig
This is for reference, these devices are supported..
You will want to look at the git log for the kernel binary in the device project that you are interested in.
Device projects are of the form device/<vendor>/<name>. This example is for the Panda...
$ git clone https://android.googlesource.com/device/ti/panda
$ cd panda
$ git log --max-count=1 kernel
The commit message for the kernel binary contains a partial git log of the kernel sources that were used to build the binary in question. The first entry in the log is the most recent, i.e. the one used to build that kernel. You will need it at a later step.
Downloading sources
Depending on which kernel you want,
Device projects are of the form device/<vendor>/<name>.
The goldfish project contains the kernel sources for the emulated platforms.
The msm project has the sources for ADP1, ADP2, Nexus One, Nexus 4, and can be used as a starting point for work on Qualcomm MSM chipsets.
The omap project is used for PandaBoard and Galaxy Nexus, and can be used as a starting point for work on TI OMAP chipsets.
The samsung project is used for Nexus S, and can be used as a starting point for work on Samsung Hummingbird chipsets.
The tegra project is for Xoom and Nexus 7, and can be used as a starting point for work on NVIDIA Tegra chipsets.
The exynos project has the kernel sources for Nexus 10, and can be used as a starting point for work on Samsung Exynos chipsets.

You may have to do some leg work and find your source.
As an example, we would build the kernel using the following commands:
Part A. Pre-build Steps
A. Open terminal and change to the root of your kernel directory
B. Type "export ARCH=arm"
C. Type "export CROSS_COMPILE=~/android/system/kernel/toolchains/arm-eabi-linaro-4.6.2/bin/arm-eabi-" (your toolchain may be different than this, it is an example)
Part B. The First Build
A. Type "make <your_config_name>_defconfig"
B. Type "make menuconfig" and make the required changes to use any modules you added or similar changes.
C. Type "make -j<maximum number of jobs>"
Part C. Re-Builds
A. Type "make clean"
B. Type "make oldconfig"
C. Type "make -j<maximum number of jobs>"
Part D. Building Modules
You have two options:
A. Type "make modules"
B. Type "make path/to/your/module.ko"
The above steps explained:
Part A.(These steps are required every time you close your terminal and re-open it to build again.)
A. Ok shouldn’t need to explain this.
B. This command sets your target architecture.
C. Defines the path to the toolchain we are going to use to compile our kernel. You can change this to point towards whatever toolchain you have downloaded or feel like using, the way it is currently configured it will use the Linaro toolchain that we downloaded above.
Part B.(These only need to be run the first time you build a kernel.)
A. Load's your configuration file from earlier.
B. Open up a menu to configure your kernel. It will use the config file you loaded in the previous step as a base.
C. Viola start the build. I typically allow 1 job per core, so on my quad core machine I put "make -j4". Just raising that number will not make your build faster, your processor needs to be able to support the number of jobs you are assigning it.
Part C. (Use the command's when you are building any-time outside of the first)
A. This command gets rid of any old/outdated binaries or modules you compiled before, and let's start fresh. I like to run it every I build unless my changes are really small and localized.
B. A very awesome command, it parses through what has changed and only prompts you about new options.
C. See the explanation for the above "Part C.".
Part D.(Use these for just building kernel modules.)
A. This will re-build all modules.
B. Will rebuild just the module you need. Very useful when you need to rebuild a WiFi module.
Outcome A. Build Succeds
W00t!! You have a kernel built by your self from source. There are a couple things you need in-order to use this kernel on your device any ".ko" modules and the zImage binary. If you pay attention to the output of your compiler then you will see the location of those objects. However the following commands will make your life a bit easier(Thanks Recognized Developer Hacre):
A. Open a terminal
B. Change to your root kernel directory
C. Type "mkdir ../<your_kernel>_output"
D. Type "cp arch/arm/boot/zImage ../<your_kernel>_output/zImage"
E. Type "find . -name "*.ko" -exec cp {} ../<your_kernel>_output \;"
The above steps explained:
A-C. Self-Explanatory
D. Move our kernel binary into our output folder
E. This handy bit of magic finds all ".ko" modules and also copies them into your output file.
You will also need to assemble a kernel image containing a initramfs for your device, along with the kernel binary and such. That however is beyond the scope of this tutorial. To get started though try searching the following phrases.
Code:
building android kernel image
xda build kernel image
xda unpack boot.img
Outcome B. Build Fails
Oh dear. It failed. Well guess what...this is going to happen..a LOT. Get used to it, and get used to googling and experimenting with different solutions. The following are some tips that will help you with debugging your issues.
Running a "Clean" build
A. Backup your config file(Type "cp .config ../backupConfig")
B. Re-run the build process using just your defconfig from earlier.
Limiting Output(Thanks Hacre.)
A. Another good tip is to run "make -j1" to get the error, as it will limit the amount of text you need to scroll through.
(from a kernel tutorial)(cred =thewadegeek)
The kernel binary is output as `arch/arm/boot/zImage`, and needs to be copied into the Android source tree in order to build the matching boot image.
Quotes from threads
"when building a whole ROM like AOSP,AOKP,PA or CM then they typically bundle the toolchain/kernel with the source, making this totally unneeded."
"You can typically find a manufacturer's configuration file in "arch/arm/configs". I believe the one for my HTC Flyer was called "flyer_hc_defconfig"
A Q&A from a thread
How can I build the latest kernel using all described stuff (aosp source, kernel config, latest kernel)?
Jean-Baptiste Queru
Mar 25
That's not possible without some work. Device-specific kernel are
typically 3 steps away from the upstream kernel: one step adds
android-specific code, one step adds chipset-specific code, one step
adds device-specific code.
THIS IS NOT COMPLETE.. IT IS A ADVANCED STEP ,LIKE STEP 8 it will take patience and time...
iT'S JUST NOT THE SAME
STEP 10
This is the step for pulling the prop file or prop blobs from a "stock" phone...
This is the script that SuperR made for the Warp2
Code:
#!/bin/sh
VENDOR=zte
DEVICE=warp2
BASE=../../../vendor/$VENDOR/$DEVICE/proprietary
rm -rf $BASE/*
for FILE in `cat proprietary-files.txt | grep -v ^# | grep -v ^$`; do
DIR=`dirname $FILE`
if [ ! -d $BASE/$DIR ]; then
mkdir -p $BASE/$DIR
fi
adb pull /system/$FILE $BASE/$FILE
done
./setup-makefiles.sh
This is one from the LGE Mako
Code:
#!/bin/sh
VENDOR=lge
DEVICE=mako
BASE=../../../vendor/$VENDOR/$DEVICE/proprietary
rm -rf $BASE/*
for FILE in `cat proprietary-blobs.txt | grep -v ^# | grep -v ^$ | sed -e 's#^/system/##g'`; do
DIR=`dirname $FILE`
if [ ! -d $BASE/$DIR ]; then
mkdir -p $BASE/$DIR
fi
adb pull /system/$FILE $BASE/$FILE
done
./setup-makefiles.sh
NOTICE: the main thing that changed was the
VENDOR=zte
DEVICE=warp2
Your proprietary-file.txt depends on your phone.
I found that during a build, it actually told me diffrent .so files it needed.
Though if you made it this far, your phone is rooted, and you probably have "root explorer"
So you may want to open that up and orient yourself with what system files are in there.
Also, you can open other prop lists from similar phones and see what files they extracted.
Here is a list that PG and associates used
Code:

Let's see if it works
STEP 11
TIME 2 BUILD
Another time when RAM will help you out.
Whatever steps you actually took to get here all depends on how much work has been put into your phone and how much of it you were able to find..
So if you have the following things done, You can continue to build if not, you better go get them.
1. Linux 64 OS
2. Build environment
3. up to date Repo
4. device repo
5. kernel source
6. proprietary files text/ extract.sh
7. prebuilts
8. ccache
9. Build command
10 Teamwork and Patience
"But Warp, you never explained some of this stuff.."
Yep, that's why there is a step about actually building it...
This next section is pulled from PG's read me
Getting my ZTE Sequent repo
$ cd ~/android/system/device/
$ mkdir zte
$ cd zte
$ git clone https://github.com/playfulgod/androi..._zte_warp2.git warp2
Note it says ZTE, not Sony, not Samsung, ETC
Then cd to the kernel directory:
$ cd ~/android/system/kernel
$ mkdir zte
$ git clone https://github.com/playfulgod/kernel_zte_warp2.git warp2
Then prop files from stock..
$ cd
$ cd ~/android/system/device/zte/warp2
$ ./extract-files.sh
When the environment is setup, we need to grab a copy of Term.apk. This is necessary to build CM10.
$ cd ~/android/system/vendor/cm
$ ./get-prebuilts
O k so I waited to tell you about CCACHE at the end. I guess I did that, because you don't need it untill the end anyway..OR is building just the beginning
You decide...
http://ccache.samba.org/manual.html
http://manpages.ubuntu.com/manpages/intrepid/man1/ccache.1.html
Ccache
There's a wonderful tool for gcc called ccache. You can read about it at their home page.
If you're always compiling the same programs over and over again — such as trying out several kernel patches, or testing your own development — then ccache is perfect. While it may take a few seconds longer to compile a program the first time with ccache, subsequent compiles will be much, much faster.
Now that we know what it is
HOW-TO-INSTALL
http://source.android.com/source/initializing.html
Setting up ccache
You can optionally tell the build to use the ccache compilation tool. Ccache acts as a compiler cache that can be used to speed-up rebuilds. This works very well if you do "make clean" often, or if you frequently switch between different build products.
Put the following in your .bashrc or equivalent.
export USE_CCACHE=1
By default the cache will be stored in ~/.ccache. If your home directory is on NFS or some other non-local filesystem, you will want to specify the directory in your .bashrc as well.
export CCACHE_DIR=<path-to-your-cache-directory>
example: export CCACHE_DIR=$HOME/.ccache
The suggested cache size is 50-100GB. You will need to run the following command once you have downloaded the source code:
prebuilts/misc/linux-x86/ccache/ccache -M 50G
When building Ice Cream Sandwich (4.0.x) or older, ccache is in a different location:
prebuilt/linux-x86/ccache/ccache -M 50G
This setting is stored in the CCACHE_DIR and is persistent. (pulled str8 from the link)
Now, we build (system being your work directory):
$ cd ~/android/system
To build for the ZTE Sequent:
$ . build/envsetup.sh && brunch warp2
All credit to PG for his readme file...Which he updated it recently, this is the old one ,I think...
Beating your head on the desk when you can't figure out why it wont build, boot , ...
STEP 12
In the true nature of a 12 step program, this process never ends.. You will always run into errors, you will always be looking for fixes, patches, and anything to correct a problem you are having.
So, basically the 12th step is TEAMWORK
I hope if this tutorial didn't suck to bad, you will come on this thread and post your questions, post your answers, post your advice. I just started
AND no, just because I made a Tutorial and finished it, it DOES NOT make me a Developer. That was a joke. You have to earn that $hyt...
But one thing i am, is motivated...
I hope you enjoyed my rendition of "HOW-TO-BUILD-FROM-SOURCE"

Wow. Thanks for the huge tutorial man!
Another piece of info.
"make clobber"
In software engineering, clobbering a file or computer memory is overwriting its contents. In makefiles, a common target clobber means complete cleanup of all unnecessary files and directories produced by previous invocations of the make command.
"make clean"
deletes any files generated by previous attempts, leaving you with clean source code
These are codes to use when
1. encountering fatal errors
2. when you "repo sync" new data
3. when you make changes to make files etc...

WARP SEQUENT N861
I am looking to compile a new kernel for this device. I have pulled off the boot.img file from /dev/block/nandc and used split_bootimg.pl to pull apart the kernel and the boot ramdisk. I have used extract-ikconfig to get the kernel config and built my new 3.4 kernel (with modules). So far so good...
I have tried to build the new boot.img file with no avail. My concern is with the original kernel as the new one should be build the same (I think). It looks like it is not compressed as I run the command
file boot.img-kernel
It returns
boot.img-kernel: data
So it is not a Linux kernel ARM boot executable zImage
Is this correct? Can Android boot with this or is the split_bootimg.pl tool not creating the file correctly (it does pull the ramdisk as I have uncompressed it fine! and the file does contain the kernel config)
Ok So assuming I can create a proper boot.img with my built zImage and the old ramdisk, what do I need to do with the modules? Do I update the boot.img on the tablet and copy the modules over to the existing /system/lib/modules? (this appears to not work)
I did not find an exact guide on android kernel and the modules....

Ok so the mkimage command can be used to pull the uImage out of the Kernel Part of the file like this:
mkimage -A arm -O linux -T kernel -C none -a 0x40008000 -e 0x40008000 -n "Linux 3.0.8" -d uImage boot.img-kernel2
The only question is where in the boot process can I find the "Load Address" and "Entry Point" values that are required to create my uImage. I would think that these are going to be needed as options when I build my new kernel, and I will need to change the boot process or add a boot.scr file with my options. I have mounted the /dev/block/nanda partition (uBoot partition) but am not certain on where I would find the current environment values.
I did find this little snippet on the net that referes to the base address for this device xxx.tabletroms.com/forums/all-other-android-tablets-general-discussion/5791-full-specs-whatever-else-polaroid-pmid10c-tablet-2.htmlx
mkbootimg --kernel boot.img-kernel --ramdisk boot.img-ramdisk.cpio.gz --cmdline 'console=ttyS0,115200 rw init=/init loglevel=8' --board sun4i --base 0x40000000 -o boot.img
But he never discusses where he found the -base address. Is this the same as the Load Address and Entry Point?

So the base address is found in script.bin (converted to text file with bin2fex tool). This is the information found in it:

Too bad I can see the souce code to find out what this program is doing or compile it for myself.....
split_bootimg.pl should give you the parameters i listed on tabletroms.
What source are you using? Polaroid never coughed any up and i last harassed them in February.

Just playing around for now to see if a newer kernel will tweek up the speed on this device as it is very laggy.

I may be using an older version of split_bootimg.pl?

think the parameters you're searching for are specific for building the new kernel without proper source code to extract them from?
maybe you could get them from dmesg while the tablet is running?
else think there might be a way to grep the variable names in the existing kernel binary or headers?
i also would like a fresh kernel.
maybe useful stuff here:

i haven't checked this out yet, but may be useful.
Well I have build a new kernel and copied the modules over, but I does not boot. It appears that it never mounts the ramdisk as it never gets to the second splash screen, but I am flying blind as there is no serial port to debug with. I suspect that I do not quite understand the boot process for this tablet.... here is what is on the nanda vfat partition: (good information here http://rhombus-tech.net/allwinner_a10/a10_boot_process/)
since this is in my linux.ini
cat linux.ini
[segment]
img_name = c:\linux\u-boot.bin
img_size = 0x80000
img_base = 0x4A000000
[script_info]
script_base = 0x43000000
script_size = 0x10000
[logo_info]
logo_name = c:\linux\linux.bmp
logo_show = 1
Not quite certain how to setup img_base on my compile I guess.
I have tried the linix.ini from the link above but the tablet booted to livesuite image... that is a fail.
Not being a kernel developer.... I am wondering if the option to setup SUNXI_NAND_COMPAT_DEV is creating /dev/block/nandX or /dev/nandX as this will definatly impact the init.sun4i.rc file as it is mounting /dev/block/nandX This could be my first issue.... but then does /init first display the initlogo.rle or start processing init.sun4i.rc. Well if the first thing it does in load initlogo.rle then I am not even getting this far....below is the description of SUNXI_NAND_COMPAT_DEV

well a little more reading leads me to this page on the CarbonRom http://www.slatedroid.com/topic/64378-rom-carbonrom-422/ turns out that if you want to run a 3.4 kernel you MUST update u-boot (http://www.mediafire...4ro667xcfkd2dv7).... so I have flashed the CarbonRom and it does boot with the u-boot update. Not to worry the new u-boot will still boot the old kernel. The only issue I have with the CarbonRom kernel is the missing dmard06 driver so no touch screen..... I may get a new kernel working yet!

the patch compiles,you need to comment out #include <linux/earlysuspend.h> as it is not supported on the newer kernel and not required by the driver anyway. I just need to get the kernel to actually load lol..... I have at least gotten past the boot screen now, but it hangs.... I will try a different arm tool chain and see what happens next.....
So close but yet so far..... well I have the new kernel installed and booted with adb shell available but it turns out the new mma7660.ko is not compatable with my device I get this error from dmesg over and over and over....

Will rename the driver and see if I can get past init further in the boot....
Edit
Well more issues with drivers the dmard06 is not compatible either, I had more success with the Carbon Kernel I will see if I can find the source git, should be around....

This all makes some sense as Polaroid has not get gotten me the kernel and the drivers they load (their kernel have very unique names:

Well more issues with drivers the dmard06 is not compatible either, I had more success with the Carbon Kernel I will see if I can find the kernel source git, should be around....

I suspect after all the trouble I had with LG source that there are device-specific bits in the drivers.
Polaroid will most likely have to cough up source to get it all working.
Have you considered trying punchmod to use the old drivers? I dunno if that'd work considering the stock kernel is a lower version... but it might be worth a try.

I have changed the vermagic on the old modules and tried with the newer kernel but no go.... the latest 3.0 sunxi kernel is at 3.0.96 so I will build this one and see if I can get the special 3.0.8 polaroid modules to load.
I have a ticket open with Polaroid lol I guess we will see if the cough up a kernel or not.... I would not put money on it...

Do you believe that something like this http://gpl-violations.org/faq/violation-faq.html could force them to provide the source code? I could try to get the group at "FreakTab" to make the same requests for the kernel sources. Maybe with enough requests the gpl-violations group could take it on?
(K I am getting off topic here sorry anyone out there......)
I have attempted to build the 3.0.96 kernel but it did not boot.... back to hacking at the .config to see what I have missed (I need to move my build environment off this old p3 800 lol)
So, I have been an Android developer since 2009 (HTC dream), and have been actively "consuming" XDA, custom ROMs and other tweaks. Surprisingly, never tried to build my own ROM from scratch.
Recently, something made me want to build the ROM, so that I can make some changes to the way SystemUI behaves (specifically putting some app shortcuts to my Pixel phone(s), like camera etc. which are now removed in Android 10). So, after a week's struggle I got to where I wanted to reach. (90% time spent in getting the first successful flash. 1% feature development. 9% feature polishing).
Here is my guide to all beginners. (It is pretty simple, if you know the steps).
System setup
I have always been a Windows user (and I love my Surface(s)), but you cannot build Android on Windows machines (as clearly called out in source.android.com). I still tried to install Ubuntu shell from Microsoft store, and build (Spoiler alert: Does not work).
Next is Mac. Android can be built in Mac, I got it build in Mac. But, it is not easy. Especially with setting up the environment, having the right version of MacOS (doesn't work on Catalina yet). And also, challenges with filesystem format (Android building only works on case sensitive file system, so you have to create such a partition). Android building needs at least 160GB of disk space (so unless you are super rich and have 512GB+ Macbook with top specs, it is going to be hard).
My choice machine hence became, my two desktops (i7 4 core, 16GB, 1TB SSD, Ubuntu 18.04 and Xeon 12 core, 32GB, 512GB disk, with Ubuntu 18.04).
There is a reason why I specifically talk about these two machines. To build Android fast (cold clean build in less than 4 hours), you need
Fast processors, and more cores
Lots of RAM
A SSD disk (with 200GB space)
If you are missing any of the above 3, you will build times will go up. I have found for hot build, both machines did a decent job (2-3 mins if you are working on single module), but SSD was more important than cores, and RAM.
Setting up your Ubuntu machine. {ETA 30 mins}
Android has official (and clearly laid out) steps here.
But for Ubuntu these are pretty much the steps.
Code:
$sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev libgl1-mesa-dev libxml2-utils xsltproc unzip
And the guide doesn't mention this, but you need Python2.7, so get this.
Code:
# refreshing the repositories
sudo apt update
# its wise to keep the system up to date!
# you can skip the following line if you not
# want to update all your software
sudo apt upgrade
# installing python 2.7 and pip for it
sudo apt install python2.7 python-pip
# installing python-pip for 3.6
sudo apt install python3-pip
Also install adb.
Code:
sudo apt install android-tools-adb android-tools-fastboot
If you have come till here, you're ready to build for different devices.
Getting the code ready to build {ETA 5 hours - 1 day}
Most of this is also mentioned in the AOSP official website, but some stuff are tricky, I will try to highlight those steps here.
We are going to build the ROM for Pixel 3 (Android 10 - QP1A.191105.003 )
Download and explode the code {ETA 2-3 hours, depending on internet speed}
Here we are talking about downloading at least 20GB of code (text heavy content) over the internet. Going to be excruciatingly slow.
Also, we will be downloading code for specific device model, so if you want to do it for a newer model, you will have to go through the grind again.
Although, technically it might be possible to have the same folder contain code for multiple devices, it is too risky IMO, something goes wrong, you lose everything.
Recommended folder structure would be
aosp --> device 1
aosp --> device 2
......
aosp --> device n
Click to expand...
Click to collapse
With each folder containing over 150GB of contents (after downloading, building etc), so in practical sense, n could be only 3-4 at max.
Setting up repo.
Repo is a tool that Google uses to checkout and manage the AOSP code in your local machine. Once you download the codebase, you can use the command to resync, update, code base.
Code:
mkdir ~/bin
PATH=~/bin:$PATH
You should persist this folder in your PATH variable all the times.
Code:
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo
This sets up repo in your machine.
One final step before you actually start the long download, setup your git details.
Code:
git config --global user.name "Your Name"
git config --global user.email "[email protected]"
Now download the code. Like I previously suggested I would do this.
Code:
mkdir ~/aosp
cd ~/aosp
mkdir pixel3
cd pixel3
Now, let's start getting the code home.
Code:
repo init -u https://android.googlesource.com/platform/manifest -b android-10.0.0_r10 --depth=1
Here we have done a bunch of things.
We have chosen a particular Android build tag to download (branch). You can follow the link to choose which branch you want to checkout, based on your test phone and Android version you want to build.
We have asked to only download the latest version of the branch and not all of the branch (--depth), this considerably reduces our download time.
Now that we have decided what to download, let's download the code with this command.
Code:
repo sync -qc -j4
This command is going to take a while to download over 20GB of code. In the meanwhile, let's see what we did here.
-q Asks the download to be silent (which means it will show just overall progress)
-c Makes sure we are only downloading current branch
-j[x] This the tricky one. Let's talk about this.
With -j we are asking repo to spawn multiple downloads (parallelly), to speed up the process. We will see this flag going forward in other places also. We should keep the value of x to number of cores we have in our machine. To find how many cores you have run
Code:
nproc --all
. Note that I have had situations where I put a very high value for n (higher than my cores as well), and eventually ran my JVM out of RAM to run the command (in parallel). So, the trade off here is to restrict it to the core number.
***Key step: Download radio drivers.***
Most tutorials miss this or mention it very subtly. But, without this step the ROM you flash won't boot to the home screen (you will be in the boot loop).
Go to the driver binaries page, and download the right zip files for the Android build version (android-10.0.0_r10) and device (Pixel 3) you chose earlier in the repo command.
You will be downloading two zip files (one vendor image zip and one radio drivers zip), both zips will have on shell script file each (.sh), just put those two files in your repo folder (~aosp/pixel3) and run the scripts. It will download the required proprietary files (after asking you to accept the terms). Do not miss this step.. I lost 3 days trying to find the reason for my ROM not booting up, this was it.
Let's build our code
Now things are more definitive.
Code:
source build/envsetup.sh
This command basically sets up your environment, adding necessary commands to path etc.
Code:
lunch aosp_blueline-userdebug
You can read more about this command here.
Basically this sets up the right parameters to build for your specific model. The param can derived based on aosp_[device code]-[userdebug | eng | user].
Once you have run the above two commands, you can *finally* build your codebase.
Code:
m droid -j4
m basically makes and builds the whole codebase.
Code:
droid
refers to the defaults target configuration (optional). -jN is to specify parallelism (equal to number of cores you have).
This command could take anywhere between 4-12 hours for the first run. But, if you followed all steps above, you should have a green message in the end saying this
Code:
[COLOR="SeaGreen"]#### build completed successfully (2:03:04 (hh:mm:ss)) ####[/COLOR]
Flashing your phone
Now, you're 50% safe when your build has finished successfully. Now, next 50% depends if you're able to flash it and get the phone booting.
This part most of you should know, so I am keeping it brief.
Enter fastboot
Code:
adb reboot bootloader
Unlock your bootloader
Code:
fastboot flashing unlock
Flash your Build
From the root folder of your repository (~/aosp/pixel3)
Code:
fastboot flashall -w
In a few minutes your device should be booting to the freshing baked ROM that you made.
What next?
You can just repeat
Code:
m droid -j4
to repeat builds
You can also go to a specific module folder and execute
Code:
mm
to only build that module
You can use adb sync to update specific modules without flashing again (this never worked for me, always bricked my device)
Use *fastboot flashall* without [-w] flag to flash over existing ROM without losing user data.
You can clean up the whole builds and rebuild everything from scratch. Run
Code:
make clobber
to clean your build, and use
Code:
m
to build again
You could face adb issues (device not detected) in Ubuntu. I am not going into details of how to fix that
This has been pretty much my journey so far with AOSP. I am comfortable making changes to modules and building them again.
Aw man, thanks for posting this. Never thought building rom itself would take this much effort & resources. Rom devs are serioulsy awesome ppl. :good:
Thx a lot ,I just want to learn it,it is vevy clear and help me a lot
Thanks very much for creating this. I didn't try flashing the result yet, but the build finished without any problems.
thank you very much for your post, I also want to modify little bit in code aosp and test this changes. Could you plaese provide advice about how I can open code (Android studio?), do some changes and test it by emulator?
thanks for the great guide
but following it gapps will not be included in the build, correct?
do you guys know how to include open gapps?
tia!
hi everything worked in this guide in terms of the build. While flashing the device all steps succeed but during boot the pixel is stuck at the google loading screen. Any suggestions. I have been stuck on the screen for > 30 minutes.

Maybe you did not download appropriate .sh scripts for your device or didn't run them successfully before building the code. These scripts additionally download files and without them you could have these problems which you mentioned.
I built and loaded AOSP Andorid 9 for PIxel 2 using the eng build vs the userdebug and its works however, when I start installing and granting Google services and such it works but i get a lot of crashes. do you have Google working and not crashing all the time?

Hello, I'm interested on the Mac os part. I've been building pixel experience on Ubuntu form am external HDD but because it's a 2011 iMac I have USB 2.0 and r/w speeds are really low slowering the whole process. On the internal drive I have a 500gb SSD that I'd like to use for compiling but partitioning is not an option, could you help me setting up enviroment?
PD: I tried setting it up with brew but I am missing dependencies I can't (don't know how) install them with brew, all guides are for Ubuntu or for Mac is but old.
Thank you in advance!
This guide inspired me to setup a Dockerized build and flash environment for the Pixel 5.
Leaving it here as Pixel 3 owners might find it useful: https://github.com/nvllsvm/pixel5-aosp-builder

Yup - it boots and seems to work except for phone call audio (T-Mobile US).
I am having issue, I did this and got:

flashing claims to have succeeded but when the phone reboots it just goes back to fastboot mode and says "no valid slot too boot to"
The last few lines of output when doing "fastboot flashall -w" are:
Erase successful, but not automatically formatting.
File system type raw not supported.
Erasing 'metadata' OKAY [ 0.007s]
Erase successful, but not automatically formatting.

Is the filesystem raw not supported normal? Other than that I am really not sure why this isn't working.
very very handy post, appreciate it, even though i would probably be not building on my own. 20GB smh.. phew!
Anyone know or figure out how to get gapps on this once built (or built-in) without having to have TWRP?
Great guide. I am working on creating a custom rom myself. I've been wondering if it's possible to prevent system apps from being included in the build. There are a few apps that I use f-droid apps in their place (example K9 mail for stock email app) and don't want to see them re-appear when the ROM is updated. If this is not possible, can they be removed from the build before flashing?
Edit ..
Figured it out.
Hi.. I'm Building AOSP 10 for POCO F1(beryllium). i dont know which command should i choose in lunch cause my device isnt listed.. They have only for Pixel Devices.. Pls guide through it
