Hello everybody.
I have a noob question about compile cyanogenmod for my new device.
Now, i have: CMW recovery, Kernel source code on local computer, full repo cm source + toolchains.
How to add my device tree, kernel source code to CM source and compile CM7 ROm?
Thanks you, cheer
Anyone here?
Did you figure it out yet? I asked the same question and am waiting for an answer, tho I'm on CM 10, HTC Vivid. If I figure it out I'll post back and try and help.

I met the same problem, does anyone can help?
Do you have a device tree? Or do you have an unsupported device? If you have an existing device tree from some other ROM, etc, then you just need to edit your .repo/local_manifest/roomservice.xml to pull in the trees that you need.
If you need to create a device tree, then it gets not complicated, as each device is different. The basic process is to create the necessary directories (device/manufacturer/model, kernel/manufacturer/model (may need to be kernel/manufacturer/device_family/model, for reference to that, see CM's repo for the LG G3) and finally vendor/manufacturer/device.
After you have the directories setup, you will need to actually start building the tree. The easiest way is to copy another devices files into your devices tree, and then edit the files. The closer the device you copy in is, the less work you will need to do to the files. Refer to sites like gsmarena.com, PhoneArena.com, etc for phone specs.
That's about as far as I can take you without dealing with a specific device. If you need more info, post back here with your questions, and post your device specs, or at least the model number,and I'll see if I can help.

I have a mt6750 devices... And there is a device from my company manufacturer.. Its a mt6750 device, it have cm device tree.. Both device working on same rom.. I can port that device rom but it always give me bugs.. So my question is how to use it?
I have been getting a lot of PM's for troubleshooting persons trying to build CM10.1 and AOKP. I myself has just started to build/understand how these things go about.
Since i have also been helped by fellow members of XDA initially, so its correct i give something back
So here it is. The following steps will help you to build your own personal builds of the same.
Iam assuming that you are familiar with building CM. If NOT, then there are tons of guide present which are useful in getting setup right.
Below steps are required to build CM10.1 for DNA
1. Initialize the CyanogenMod source repository
cd ~/android/system
repo init -u git://github.com/CM10DNA/android.git -b cm-10.1-chad
2. Download the source code (It takes mighty long time) :fingers-crossed:
repo sync
3. Get prebuilt apps
cd ~/android/system/vendor/cm
./get-prebuilts
4. Prepare the device-specific code
. build/envsetup.sh
5. Start the build
brunch dlx
After build process is completed, it will show the exact path where the .zip file is stored :highfive:
Next up will be AOKP. I will update this thread with the steps if there is interest in it.
If i helped, hit THANKS button :highfive:
Would please add the steps for aokp? I've already got aokp and chads cm source downloaded, just not sure what to do next. Thanks!!
I just want to add if nobody has built anything before, there's a lot of things you need installed before you can do this. You can find tutorials that tell you everything you need to build a ROM from the source. I remember seeing one in the nexus 7 forum and I think one in Android general

Need a slight tweak...
I noticed that there is no current port going or started for ubuntu touch, so today i thought i would start that project.
the first thing i noticed was that ubuntu's documentation for porting is one of the worst things ive ever seen, so this will probably end up being kind of a guide until we get a working image or something.
first thing is you will absolutely need Linux. Im using ubuntu for ease of use, although I do build android on arch.
I set up a directory structure on my pc just for android development. i have ~/android/platforms/ in which i have cm11, ubuntu-touch carbon, etc.
so to summarize how i got this started:
Code:
$ mkdir ~/android/platforms/ubuntu-touch-phablet-4.2.2_r1
$ cd ~/android/platforms/ubuntu-touch-phablet-4.2.2_r1
$ repo init -u git://phablet.ubuntu.com/aosp/platform/manifest.git -b phablet-4.2.2_r1 && repo sync -j16
Now im really hoping that is the correct branch. I tried to follow the "porting guide" and its just full of out dated information that lead me to sync a few repos incorrectly. :silly:
after a few failed builds and some common error logs i finally figured i was on the wrong branch. This attempt shall be on 4.2.2_r1 as that appears to be the latest. (I hope)
anyway the rest is still in progress. My sources will be on github for people to help out.
Device
Kernel
also: im on irc on freenode at #oudhitsquad pressy4pie
[update]
i have a huge problem in the real world, so i will have virtually no time to get this updated for now. I am really sorry, hopefully i can get it going again soon

cool mate! thanks for that...cheers!
Nice. Would love to give a hand here, I'll visit the Ubuntu workshop at devcon this weekend to learn some new fresh information about porting. Maybe I'll give it a try later too.
Good news!
Looking forward to see the first builds getting ready for testing.

This will take a while. As you can see in OP, there are problems with the porting guide from Ubuntu. When I get back from devcon, I hope to know more about porting.
So turns out i was in fact syncing the wrong repo again. shame on me for following a ubuntu guide. it appears there is a 4.4_r1 repo also. Syncing again. I have a fairly slow connection. ill see what i can get done on 4.2.2_r1 though in the mean time
I have high hopes...
Would like to a working rom.. Wish you best of luck and hope its smooth sailing...
Thanks for scarifying your time and efforts for us
Couple of month ago I wanted to port it for my lenovo phone, but I gave up (sources limited)
Anyway, to say that I went on the IRC channel to get some support, they are willing to help (even though you have to be patient, it's IRC, hundreds of people connected nobody on their computer.). So they told me that (as you noticed) the porting manual is outdated, and they are now basing their port on AOSP. Tthis should not be a problem to use CM though.
So try to get some help there, they know what you have to do
I could give a hand, I have a good internet connection. Could you post all the command history you ran, so I can try on my side?
cheers
ive got some progress, i think.
ubuntu-touch has rebased to aosp rather than cyanogenmod, which makes things a lot more difficult.
if youve ever tried to build something that is not a nexus device against aosp it is a huge pain in the ass. Bacon has a lot of cm specific parts that need to built so it is difficult to get it to build w/ aosp. but to explain where i am currently, i synced 4.4_r1, and now since aosp doesnt build kernel and bacon requires kernel to be packed up with dtb and stuff, i went to my cm11.0 repo, did my ubuntu-touch modifications to kernel, did
Code:
lunch cm_bacon-userdebug && make -j32 bootimage
which (i think) gives me the correct bootimage. What we need now is the android part. i am building inside the ubuntu-touch-4.4_r1 dir with:
Code:
lunch aosp_bacon-userdebug && make -j32 systemimage
that eventually errors out to:
Code:
make: *** No rule to make target `out/target/common/obj/JAVA_LIBRARIES/core_intermediates/classes.jar', needed by `out/target/common/obj/JAVA_LIBRARIES/qcmediaplayer_intermediates/classes-full-debug.jar'. Stop.
make: *** Waiting for unfinished jobs....
im not sure why because as far as i know, ubuntu-touch shouldnt be building java parts and that is the first part of building the java stuff in a regular android build. ive never ported ubuntu-touch before. so someone let me know if ive messed something up. i dont think there is something in the device makefiles that starts the java build.
any help
just in case, are you using opensources java or oracle one? I am pretty sure it doesn't work with opensource java. But i would expect that you get the error earlier...
I'm not sure if you already have this or not but Oneplus has aosp kernel sources at https://github.com/OnePlusTech/android_kernel_oneplus_one .

im using oracle, but that isnt the problem. Ubuntu-touch takes the java out so its not there for a reason but something is causeing it to want to build the java parts..
i think im going to go ahead and fork hammerhead which i know builds, and give it 1+1 parts.

Good Idea! Let us know
I met @ciwrl at devcon, he'll come here and tell you how to squash that problem.
Great to see someone working on it.

News?
This is exciting to see, I'd love to try Ubuntu touch on the OPO. I have Ubuntu, but I'm mainly in Linux Mint, or Kali. Let me know if there is anyway I can assist with testing, Web storage/hosting, etc.
@konnorrigby, as @ciwrl suggested at devcon, you should disable the whole java part from the build. Ubuntu doesn't need any of it to build and run.
Wow! I really want to see Ubuntu on my OnePlus one. really Excited. Good luck guys
This has been started for people interested in porting other ROM's for the Nubia Z7 Mini (NX507J). If you are interested in seeing/using/asking questions about ROM's that currently exist, please use the thread created by @Seyron here. I previously posted the following information on that thread, but feel a new thread will be better so the other can be used for people with questions about existing ones.
I'm not sure what you mean by a good background for going at it; however, I think having a good understanding of computers and even some basic programming is very helpful. As for myself, everything is self-taught. I'm pretty familiar with mac, PC, and linux. Even if you are completely new at it, there is lots of good information out there - I would just encourage you to start by learning from credible and well established sources. I have only tried porting for nubia Z7 mini - no other android. I previously used the iphone (and am frankly glad I now have android).
It really depends on whether you want to do a simple port (that's how I call it - don't know if there's an official way of calling it) or port from source. If you are doing a simple port, you can use any computer (mac, pc, linux); however, if you want to port/build from source it is by far the easiest to do it from Linux. There are many resources out there for building/porting from linux - most of which are using Ubuntu. I personally use Debian (which incidentally Ubuntu was created from; however, they are now each distinct and different), but you could use most any linux distro as long as you are comfortable using the command line. Also, if you are using linux, make sure you have enough hard drive space available (most recommended is at least 30GB) and have enough RAM (I have 16GB - minimum recommended is 8GB). It's also very helpful if you have a large swap set up as it makes building go faster. Once you have everything put together, compiling/building takes 3-5 hours depending on the specs of your computer. I have a 1.7ghz i5 in my computer and it is slow - 4-5 hour range for me.
For the sources list below, please note I have no affiliation with them and do not know them. Use at your own risk, I assume no responsibility for what may happen to your computer or phone.
I think some of the best (and frankly most detailed) information comes from the android source code website and from XDA-University.
https://source.android.com/index.html
XDA-University
For what I call simple porting, can be done on any computer - this was the site I started with and it seemed to work except that I kept getting boot loop issues. There are many other sites out there with nearly identical information. This person uses a PC, but you can adjust it quite simply for doing this on mac or linux too:
http://seekandroid.info/2014/05/porting-android-roms-for-your-phone.html
The following site/instructions are very interesting as they are different than any other site I found out there with porting instructions. I have not done it this way - primarily because I am concerned about "bricking" my phone. The method this person uses is the same; however, the files that they transfer are opposite to most any other site I've found. I have not used these instruction - be very cautious until someone else can confirm.
http://anythingsyouneed.blogspot.com/2014/06/how-to-port-custom-rom-rom-porting.html
This one seems interesting; however, I have not used anything on this website and have not used one of the Kitchen programs.
http://www.littlegreenrobot.co.uk/tutorials/how-to-cook-your-own-android-rom/
Android - excellent and very detailed. Personally I think most helpful to those with intermediate to advanced programming knowledge. Or at least have the ambition and time to learn.
https://source.android.com/source/building-devices.html
XDA-University - Truly amazing wealth of information, approachable for anyone from absolute beginners to advanced programers.
http://xda-university.com/as-a-developer
http://xda-university.com/as-a-developer/porting-aosp-roms-using-source-code
I've been busy and haven't had a chance to use these pages yet, but it's what I'm going to do next to try and solve the boot loop errors.
http://xda-university.com/as-a-user/zip-based-rom-tweaking
http://xda-university.com/as-a-user/how-to-recover-from-a-bootloop
If anyone has anything to add, please do. I'd be interested in seeing what else people use.
I haven't found the required sources to port from source, so I don't know if that's possible. Neither am I experienced in any of that.
In basic porting I do, however so far it has been unsuccesful for the Z7 Mini.
I have tried to port CM11S from the OPO, but it didn't work out, the phone became stuck in a bootloop, and logcat wasn't working to find out what's the problem of not booting. Might be dual-sim related but that should more likely run into a non-working sim/ril or a lot of crashes, not making it not booting at all.
I do wonder how they got the CM11 / Mokee with eng/ch languages to work. Tried using those as base too but that didn't do the trick.
To build completely from source you need to have the kernel source.
ZTE has not yet released it, but I'm hoping it will be released soon.
You can check here.
On Github there's a repo but it's apparently broken.
Anyway you can build cyanogenmod without having the kernel source (http://wiki.cyanogenmod.org/w/Doc:_porting_intro)
As soon as I get my own device I'll try that.
Nice, will follow this thread
I was trying to port the Z7 Max CM11 to the Z7 Mini, still work in progress because i'm new at this...
So, do you have any idea how the existing ROM's were ported then? If they weren't from source, we should be able to port others without getting the boot loop error - in theory. Not finding the kernel source is the main reason (besides finding the time) why I haven't worked on porting others. I also cannot find the vendor tree for the phone - which incidentally, may well be part of the kernel source. If you can port CM without source the others should be equally possible. Personally, I'm not interested in a CM based ROM (although a couple I listed in the other thread that I tried porting were CM based); I'm more interested in an AOSP based ROM. I wonder why ZTE has been so slow to release the kernel? Especially since they've released all the others (albeit not the other Z7's) and they have been so popular.
Also, as I stated in the other thread, I was able to get a couple to boot, but they were stuck in boot loop issues. I forgot to use logcat to see what the issue was.
@voetbalremco I agree with you, how did they get MoKee and MIUI to work? I tried using MoKee as base too - though didn't try MIUI. Does anyone know if it's possible to extract the kernel from the current stock ROM?

There are different ways to port a Rom...or you build it from scratch, so you compile everything. And for that you need source for every component.
Or you can use the various kitchens (this one for example) to repack and tweak an existent rom.

You can do it with the kitchen above or using one of the tools available (like this one for example.
Probably everything can be done with dd (as mentioned in the cyanogenmod guide).
Hopefully my device will be her soon, so I can also try these as well

Thanks for the resources! I think combining those two, plus the info on the CM website, and what's on XDA-University; I should be able to get this figured out. Now all I need to do is find the time.
Today my phone arrived! Tomorrow I'll pick it up and start to do some tests.

I thought that was the kernel that was either incomplete or broken. Do you know otherwise? I had seen it previously, but had read there were errors with it. If not, that's great! I also wonder if it has the "fixes" that ZTE has made for wifi, BT, etc in the recent updates.

Thanks. Although, one person commented on the thread that it is nubia development and isn't open source yet. Won't know for sure and I'm not totally sure how to tell from looking at it. May have to keep waiting - or at least dig a little deeper. Thanks again.
So I started to try to build something with CM-11.
I thought I could put my steps here, in case someone else needs them (or has a better way to do it):
1) Get the repo uility:
Code:
mkdir ~/bin
PATH=~/bin:$PATH
curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo
2) Initialize the repository:
Code:
repo init -u git://github.com/CyanogenMod/android.git -b cm-11.0
3) Sync the repository:
Code:
repo sync
This will take a while (the repo is pretty big).
I've taken some infos from the phone (build.prop, partitioning, kernel, boot.img).
I'll continue as soon as the repo is sync'ed.
Repo sync'ed, now build the environment:
Code:
. build/envsetup.sh
At this point we have to build the structure as explained here
Make sure you have the boot.img extracted (see previous posts about a tool).
Make sure you have the utility "unpackbootimg" installed.
I downloaded from https://github.com/osm0sis/mkbootimg/blob/master/unpackbootimg.c and compiled with:
Code:
gcc -o unpackbootimg unpackbootimg.c
Put it in your $PATH.
Then run the commands to create the directory structure:
Code:
./build/tools/device/mkvendor.sh nubia NX507J ../original/boot.img
"nubia" and "NX507J" come from the build.prop, respectively
Code:
ro.product.manufacturer=nubia
ro.product.device=NX507J
The result from the mkvendor.sh is:
Code:
[...]
Use the following command to set up your build environment:
lunch cm_NX507J-eng
And use the follwowing command to build a recovery:
. build/tools/device/makerecoveries.sh cm_NX507J-eng
...to be continued

Did you see the post by yiphoming on the other thread that CM11 already exists? Any other ROM's you're interested in?
Hey guys...hoping someone here who is wiser than I can offer some information on how I might complete the task I am after. I've got limited knowledge in the rom-building department, but would really like to learn at least enough to "get my feet wet" so to speak, and so I'm trying hard to do just that. I would like to build a version of SlimKat based on the latest code available, and have it be compatible with our device (the VS985). I've gotten so far as to set up the Ubuntu build environment and everything, installing repo and initializing the directory with the SlimKat 4.4.4 caf (by doing repo init -u git://github.com/SlimRoms/platform_manifest.git -b kk4.4-caf), and finally repo sync'ing the whole thing.
I'm pretty sure that I need to eventually use the ". build/envsetup.sh" and then "brunch vs985" commands to begin the actual build process itself, but my main question now even after all the tutorials I've read is whether or not there are additional "device-specific" commands I need to run or things need to do or sync in order to make the final product compatible with our VS985. I found a tutorial on building CM11 for our device, and it talked about having to create a local_manifest.xml file and then repo sync'ing again, but this is pretty much where I got lost and where I'm still quite confused. Can anyone with prior AOSP building experience help me out with some idiot-friendly () pointers/instructions and explanations on where to go after repo sync'ing? I would seriously appreciate any help anyone can offer. Thanks!!

I'm pretty sure that I need to eventually use the ". build/envsetup.sh" and then "brunch vs985" commands to begin the actual build process itself, but my main question now even after all the tutorials I've read is whether or not there are additional "device-specific" commands I need to run or things need to do or sync in order to make the final product compatible with our VS985. I found a tutorial on building CM11 for our device, and it talked about having to create a local_manifest.xml file and then repo sync'ing again, but this is pretty much where I got lost and where I'm still quite confused. Can anyone with prior AOSP building experience help me out with some idiot-friendly () pointers/instructions and explanations on where to go after repo sync'ing? I would seriously appreciate any help anyone can offer. Thanks!!

It all depends. If the source you grabbed does not have anything specific for the vs985, then the build command itself won't work. The build scripts and configuration has to be modified to add that build command and even then, it means going into the source and making whatever changes you need to make it specific to the VS985.
Since it's AOSP, it should work no matter what, but that means anything that requires vs985 specific calls to make it work aren't there.
It's not just a magic command that makes it work. You have to go in and figure out what isn't and is working and make the necessary changes.
I'm assuming you are a programmer? If not, better learn.

I see. I have had some very basic programming exposure, but I wouldn't consider myself anywhere near skilled and it's been a while haha. Well I do appreciate the info and I'll probably be best off leaving this to those much smarter than I Thanks!

I don't want to scare you off. If you feel like you want to learn something new, then don't hold back. I just wanted to let you know that it's not just a simple "grab the source from another phone and compile it for the G3". That's why you'll see different ROMs for each of the different phones. But, in the case of this phone, you all have to add the bump to the ROM in order for it to work and that is specific to each version of the G3. You can't take a bumped D850 (AT&T) ROM and just flash it onto a Verizon G3 (VS985). It won't work.
Now, bumping is not that hard as one of the posts on how to compile a ROM for the G3 gives you the instructions to "bump" your ROM, which is done after you've compiled it. Where it gets more difficult and requires some more tech savy and programming knowledge, is how to modify the ROM to take advantage of the hardware specific to the G3. The AOSP code pulled down for say CM11/CM2 is just that - AOSP. What you were doing was taking a completely different ROM's base source and trying to make that work on the G3. Not impossible by any means, but would require more than just a basic understanding of programming. You also need to understand how the Android OS works, etc. Again, not a trivial task by any means, but also, could end up being something that challenges you to learn more and eventually become a contributor to the G3 dev forums.
I myself am a programmer. I've been learning Android app development but I also wanted to delve into ROM building and was grateful to see the post on how to do so, so I'll be looking into that when I can, but I know it's not an trivial thing to master, but I'm a persistent person and most of my computer programming I learned was self taught when I was in high school on an Apple ][+ and //e. Those were the days when Apple wasn't so closed. Woz had a hand in wanting to keep it open - Jobs didn't. We all know who won on that count.
Any ways, if you are up to a challenge and like solving problems, programming is definitely the way to go.
I've been trying to build my own just for fun as well, but after I brunch, it doesn't create a zip.
I've been following this guide: http://forum.xda-developers.com/lg-g3/general/guide-how-to-build-cyanogenmod-11-d850-t2971538
I feel like it has something to do with my local_manifest.xml, but it's probably because I tried building CM12 and it's not as easy as just changing the branch...
Probably just going to start over from scratch with CM11 and see how it goes.
