bootloader: Locked and Signed Irrelevant
uboot: CRACKED BY BAUWKS
THANKS TO BAUWKS
Loglud said:
bauwks method uses the flashing_boot.img to his advantage, and since it is not checked by security, effectively he has made an insecure uboot. While this is not an unlocked bootloader, it is a way to get around the security, and enable custom recovery and higher level processes to be run.
I have been looking at this line of code for a long time, and as im sure hkvc and bauwks saw it is a large (but 100% necessary) flaw:
distro/u-boot/board/omap4430sdp/mmc.c: 559 : setenv ("bootcmd", "setenv setbootargs setenv bootargs ${sdbootargs}; run setbootargs; mmcinit 0; fatload mmc 0:1 0x81000000 flashing_boot.img; booti 0x81000000");
Without this line of code, it would be impossible for any one but the factory whom could JTAG flash (but since it is secured, most likely they also have to make a flashing_boot.img).

Keep in mind this is only an overlay verson but it is prof that one day we might be able to push roms and kernels over existing ones, then hijack then (next work) and then use them.
Please PM me or post if you know anything else, and or want to add anything.

Enableing adb Connection (eab1)
Install the andriod SDK that is required for your Operating system.
NOTE: This will requries the SDK, and JDK both of which can be downloaded by clicking the links, downloading and installing it.
Run the andriod SDK Manager and Install "Andriod SDK Platform-tools"
[*]Modify your adb_usb.ini file to read such as the following:
Code:
# ANDROID 3RD PARTY USB VENDOR ID LIST -- DO NOT EDIT.
# USE 'android update adb' TO GENERATE.
# 1 USB VENDOR ID PER LINE.
0x2080
This will be in your /home/{username}/.andriod/ folder for mac and linux
This will be in your C:/Users/{username}/.andriod folder for Windows.
ADB is now enabled for your device, however it is not ON your device. YOU MUST DO THIS EVERY TIME YOU WISH TO ADB INTO YOUR DEVICE.
[*]To do this you will need to download any app, and attempt to install it.
You can use this app if you need.
[*]Click on the Package Installer, and then a prompt will pop up asking if you want change the settings to allow 3rd party apps.
*DO NOT ENABLE IF YOU WISH TO ACCESS ADB*
I am working on a way to have it enabled by default.
[*]In the settings page you should see *2* USB Debuggin modes.
[*]Press them both and accept the prompt.
[*]PLUG IN YOUR DEVICE.
Note* You should see the Android Development icon on the bottom of the screen.
ADB will now be able to see your device. How ever you will need to restart the server before it sees it.
Rooting using zergRush (rug2)
This is for the poeople whom have access to adb. You will also need this file. Unzip the file.
Type in the following command (while in the folder with the zergRush Binary):
Code:
adb push ./zergRush /data/local
[*]Once thats installed run this:
Code:
adb shell chmod 777 /data/local/tmp
[*]And lastly:
Code:
adb shell /data/local/zergRush
[*]You are now rooted (only for this reboot)
Installing busyboxy (ibb3)
You will need root and the following busybox file.
Type in the following command while in the location where busy box was downloaded to:
Code:
adb push ./busybox /data/local
[*]Busybox works by calling binaries from a file outside of /system/bin/. We must make this file by issuing the following command:
Code:
adb shell mkdir /data/busybox
[*]Lets make sure we can install busybox without permission probles:
Code:
adb shell chmod 777 /data/local/busybox
[*]Next install busybox in the folder:
Code:
adb shell /data/local/busybox --install
[*]We now need to take the /system/folder, and mount it as a writeable folder:
Code:
adb shell mount -rw -o remount /dev/block/platform/mmci-omap-hs.1/by-name/system /system
[*]Link it into bin:
Code:
adb shell ln -s /data/local/busybox /system/bin/busybox
You now have busybox installed
Permanent root (pr4)
THANKS TO INDIRECT for Files and Scripts
We will need SU and Superuser.apk
First we need to install the Superuser.apk:
Code:
adb wait-for-device install Superuser.apk
adb remount
[*]Next lets go ahead and push the su application up to the /data/local/ folder
Code:
adb push su /data/local/
[*]Next we will need to change the permissions and cp su from the /data/local/ folder to the /system/bin/
Code:
adb shell chmod 4755 /data/local/su;mount -o remount,rw /dev/block/platform/mmci-omap-hs.1/by-name/system /system;busybox cp /data/local/su /system/bin
Installing GApps (eab1)
THANKS TO ANALOG and INDIRECT for Scripts
First things first we need to download the GAPPS. The most reacent one is this one or get the most recent one here.
[*] Unzip and navigate to the most root folder of that package in your shell.
[*]We need to verify that adb is booting into root. To do this we can issue the command:
Code:
adb shell id
If id doesn't return root then you will need to re-zergRush your device
[*]Now it is time for us to export the apps to the directories.
Code:
adb shell mount -o remount,rw /dev/block/platform/mmci-omap-hs.1/by-name/system /system
adb push system/app/CarHomeGoogle.apk /system/app/

Your nook will now restart and tell you it is resetting.
You now have a clean slate!
Got some links for howto's on the adb connection/root.
Yeah - if someone has details on how to adb connect and root, it'd be helpful to include links. I've yet to see specifics for either.

CURRENT PROGRESS
adb connection: COMPLETE
adb root: COMPLETE
busybox: COMPLETE
permanent root: IN PROGRESS
bootloader: Locked and Signed
By the bootloader being locked and signed it is very difficult to design anything that will boot besides nook roms. In order to solve this some of the Devs have suggested the following:
kexec: RESEARCHING
2nd init: RESEARCHING
CWM: NOT STARTED

hopefully it is cracked soon cause i dont want to buy this if i can't have a full custom rom, all of the verizon motorola phones run roms off of 2nd init and it just isnt the same to be honest. you can never run a full custom rom with second init(well you can but you have to build the rom to fit the kernel) and honestly i want my device to be mine
you should tweet cvpcs or someone who makes and maintains 2nd init roms to get more info on it though
Can't get busybox installed
I'm stuck... I get errors for #3 for busybox... errors like...
Code:
$ adb shell /data/local/busybox --install
busybox: /data/busybox/[: No such file or directory
busybox: /data/busybox/[[: No such file or directory
busybox: /data/busybox/addgroup: No such file or directory
.....
busybox: /data/busybox/yes: No such file or directory
busybox: /data/busybox/zcat: No such file or directory
busybox: /data/busybox/zcip: No such file or directory
So I logged into root via adb shell, set busybox permissions to execute and tried that but same messages?!
Also, adb won't let me 'remount' - (I thought i'd try to copy it direct to /system/bin)?
(I'm running from OSX, if that matters)
EDIT: and of course I'm getting...
Code:
$ adb shell ln -s /data/local/busybox /system/bin/busybox
link failed Read-only file system
$ adb remount
remount failed: Operation not permitted

Sorry it took me so long to get back to you. I have updatd my guide to help you out. First of you will need to make the busybox directory, then change the permissions of the binary file, then run the install. You will then have to mount -rw
Still some glitches installing busybox...

Thanks Loglud, but I still had trouble using adb. It's like I don't have root from adb? I get permission errors on mkdir and remounting etc?
Weird that the 'adb shell mkdir /data/busybox' gave me permission errors?! It did work fine with the interactive adb shell - weird!?
After the initial 'push' command, I could install via:
Code:
mac-osx$ adb shell
$ su root
# cd /data/local
# chmod 755 busybox
# ls -l
-rwxr-xr-x shell shell 1745016 2011-11-21 00:21 busybox
# mount -rw -o remount /dev/block/platform/mmci-omap-hs.1/by-name/system /system
# mkdir ../busybox
# ./busybox --install
Also, is the line:
Code:
# ln -s /data/local/busybox /system/bin/busybox
not supposed to be
Code:
# ln -s /data/busybox /system/bin/busybox
Things went weird on me in the final step, but I did manage to get all the hard linked busybox files to show up in /system/bin eventually, so I'm a happy camper.
EDIT: PS my mount on data is as follows..
Code:
# mount|grep /data
/dev/block/platform/mmci-omap-hs.1/by-name/userdata /data ext4 rw,nosuid,nodev,noatime,errors=panic,barrier=1,data=ordered 0 0
EDIT2:
Hmmm... seems like maybe my /data folder has weird permissions - if so not sure why?...
Code:
# cd /
# ls -l | grep '\<data\>'
drwxrwx--x system system 2011-11-21 18:25 data
# chmod 777 data

ok so whats happening? i modified the guides and i was hopping that would help you. The command is
Code:
# ln -s /data/local/busybox /system/bin/busybox
and as for your permissions it seems as though your root since your in the # shell but, you have to change the permissions on your /system folder not the /data folder the permsisions on the data file should be fine since i think shell is a member of system, so you can put all your data in there.

Yeah, I'm root in the 'adb shell' because I 'su root' but adb commands fail from the Mac shell. I'll reboot my NT and give you the script. My /data permissions get reset when I reboot...
Here you are as it happens
MBAir$ ls busybox

MBAir$ adb push ./busybox /data/local
2881 KB/s (1745016 bytes in 0.591s)
MBAir$ adb shell mkdir /data/busybox
mkdir failed for /data/busybox, Permission denied
Of course there is no point continuing until I do the following...
MBAir$ adb shell
$ su root
# chmod 777 /data
# exit
$ exit
MBAir$ adb shell mkdir /data/busybox
MBAir$ adb shell chmod 777 /data/local/busybox
MBAir$ adb shell /data/local/busybox --install
MBAir$ adb shell mount -rw -o remount /dev/block/platform/mmci-omap-hs.1/by-name/system /system
mount: Operation not permitted
To get around the last error, I had to do another 'adb shell', 'su root' and do 'ln' commands manually.
(I actually ran a shell 'for loop' on the tablet, using all files found in /data/busybox as a list and issued ln commands for each against a copy of busybox in /system/bin)

re run zergRush exploit. your adb shell is defaulting to the shell username. by rerunning the zergy you will allow for yourself to use the adb shell as root. make sure you dont run it as the root user though. you are also more then welcome to hop in irc and ask questions.
Any one having difficulty rooting or see anything that needs to be updated?
hi
i need to push a file with adb
but adb push give me permision deny
how can fix this?

In some rom adb permission isn't root by default. I think it's a line in default.prop that enable root in adb. Something like
ro.adb.secure = 0
if you don't want to edit that file just push file to sdcard or temporary folder then use adb shell (with root) to copy that file to proper location.
but 2 days ago adb work like acharm in this rom!

That's strange. Maybe in your rom adb push works only when file doesn't exist.
no. i push framework-res.apk 5 days ago & it work! framework-res.apk is exist already
but i test this file again & permision deny!
How about su before the command? Or adb remount, to get write access?

I have the same problem too and remounting the adb doesn't solve it.
I'm still searching for a fix. I can only pull but not push.
If y'all are on a stock rom, then you can't push anything directly into the system (unless your bootloader is unlocked & you modify the boot.img). I use the following mount command
mount -o remount /system
First push the file to the sdcard
adb push blablabla /sdcard
then adb shell it to the correct location.
It's a lot of bs but it's the only way I got it to work with stock.
Here's an example of a batch script I made
Code:
adb push LGSystemUI.apk /sdcard/
adb shell su -c "mount -o remount /system"
adb shell su -c "cp /sdcard/LGSystemUI.apk /system/app/"
adb shell su -c "chmod 644 /system/app/LGSystemUI.apk"
adb shell su -c "killall com.android.systemui"

I have a non-rooted Android device with stock ROM 4.4.2 and I have the following test shell script:
Code:
adb push test.sh /data/local/tmp
adb shell "cd /data/local/tmp; chmod 755 test.sh"
adb.exe shell "sh /data/local/tmp/test.sh > /dev/null 2>&1 &"
If I run this over ADB from PC to my device, it simply works.
Now convert this to:
Code:
cp test.sh /data/local/tmp
cd /data/local/tmp; chmod 755 test.sh
/system/bin/sh /data/local/tmp/test.sh > /dev/null 2>&1 &"
and it doesn't work. It says permission denied on /data/local/tmp.
Is there any other EXT4 place on a non-rooted device that I can do this?
Well, I cd to /data/local/tmp and even submitting a 'ls' command inside Terminal Emulator doesn't work, it says permission denied, but when doing it from PC to Android using ADB it's fine. Is there any workaround for this? I want to be able to do this on the device itself.
Thanks

No there isnt, not if you try using /data partition. ADB can read this partition (and that too was added around android kitkat itself for purpose of adb backup
etc). So ADB can read this partition, but terminal emulator and such cannot.
Assuming that you have a great reason to simply not copy the sh file to user-usable internal memory, /system partition is the one place where you can copy things without actually having root (and even access them with terminal emulator, but not manipulate them), and this isn't that simple either. Rather, the method will be device dependent. For instance, if you have a phone like Nexus phones, simply download stock firmware, open/extract it depending on what format it is (img or tar), add your sh file and repack the firmware, then flash it into the phone. The firmware should be same as your current installed so your applications dont mess up. But this method is not only long (and messy if your device has integrity checks on firmware files), but also not possible on some phones (as far as I know).
You can also try copying the sh file with adb to /data/data/com.android.terminal. Then you should be able to access this with terminal emulator (since an app has permissions inside its own data folder). However I have not tested this method and I am not sure it will work.
Besides this, every app (including terminal emulator) runs in a sandbox and does not have access to anything except /system (read-only access), emulated user-storage and its own data inside /data/data/. So in phone itself, you cannot read the file unless you copy it to /system or user-memory. And this finally implies that except above two methods, there is no other way to copy file to some other place except user-memory and be able to read it using some app inside phone itself without rooting.
Thanks for your comprehensive reply. I resolved the problem. Yes, it's right, I can simply run the shell script without even moving it to /data/local/tmp... so now I can conveniently running it directly from my phone without having to turn a computer on and do it over ADB.
thankx
Does anyone has a copy of the original build.proc of version 4.0.3 tablet s? Can you share?
I might have screw up mine...and it's not loading.
After adb is successful, does anyone know the command to push the build.proc into /system?
I have a back up in system/build.prop.bak
I have an adb access and device recognised. can anyone help me and provide the steps (one by one) to get it renamed?
I tried to push one copy from my pc but it fail because it is read-only file system. How can i make it R/W?
Here is the commands 2do:
Code:
adb devices - check if u device is recognized
adb pull /system/build.prop C:\...\ - get build.prop file
edit how u want
Code:
adb shell
su
mount -o rw,remount /system
//Come back to ADB
adb push C:\...\build.prop /system/build.prop - repush build.prop file
adb shell chmod 644 /system/build.prop - fix permission
adb reboot
Hope this can be helpful
Thanks! Let me try...
