Huawei Ideos Super FAQ

This is an FAQ for the Huawei Ideos as there have been many questions on how to do the same things. Hopefully this should help. There are other FAQs but this one tries to compile as many as it can into one FAQ.
Feel free to reply to this if there are any questions or if you want me to make any additions. The FAQ won't be complete to begin with but I will add as I get time.
One thing I will say is that I WON'T TAKE RESPONSIBITY IF YOU DAMAGE YOUR PHONE. I AM PROVIDING THE INFORMATION AND WILL TRY TO HELP YOU IF SOMETHING BAD HAPPENS BUT I CAN'T TAKE ANY RESPONSIBILITY
1. How to root the IDEOS
This can be done quite simply by adapting what quail wrote:
There is a couple away you can go about gaining root access with this phone I have tested all 3 ways but only had success with 2 of them.
a) You can download 'z4root' from here (WORKS)
b) Search the XDA forums for 'SuperOneClick' which requires mono to work on Linux. I have read people that have had success with 'SuperOneClick' but that was not the case for me. (HAVEN'T CHECKED)
c) My preferred method: (HAVEN'T CHECKED)
Prerequisite:
knowledge of Linux and Terminal
knowledge of ADB (guide available in forums)
I did all this using Debian (testing) 64bit, Android SDK.
Creating correct permissions to access the phone via USB:
i) create
Code:
/etc/udev/rules.d/51-android.rules
ii) in the file put
Code:
SUBSYSTEM=="usb", ATTR{idVendor}=="12d1", MODE="0666"
iii) then
Code:
chmod a+r /etc/udev/rules.d/51-android.rules
iv) restart udev or reboot
Downloading and/or Installing required software:
1) Downloading and installing the android-sdk from: developer.android.com/sdk/index.html
2) Downloading and extracting 'SuperOneClick' (you will only need these 5 files: rageagainstthecage, sqlite3, su, busybox and superuser.apk)
3) Copy rageagainstthecage, sqlite3, su, busybox and superuser.apk into the platform-tools directory of android-sdk. Put phone in debug mode.
4) From a terminal (command line) change to the android/platform-tools directory and carefully do these steps.
Check to see if adb can see your phone properly:
Code:
./adb devices
You should see the serial number of you device, if you see bunch of '?' you have done something wrong.
Now for the fun part rooting the phone: <= no phun intended hehe
Code:
./adb push rageagainstthecage /data/local/tmp/rageagainstthecage
Code:
./adb shell
Code:
cd /data/local/tmp
Code:
chmod 0755 rageagainstthecage
Code:
./rageagainstthecage
5) Now wait until you get kicked out from adb before you do the following:
Code:
./adb shell
If everything worked now you should see a "#" instead of the "$" you saw previously in the adb shell which means you shouldn't get "permission denied" in the following steps:
Code:
mount -o rw,remount /dev/block/mdtblock4 /system
Code:
exit
Code:
./adb push su /system/bin/su
Code:
./adb push busybox /system/bin/busybox
Code:
./adb push sqlite3 /system/bin/sqlite3
Code:
./adb push Superuser.apk /system/app/Superuser.apk
Code:
./adb shell
Code:
cd /system/bin
Code:
chmod 4755 su
Code:
chmod 4755 busybox
Code:
chmod 4755 sqlite3
Code:
./adb reboot
Now you should be able to use apps like 'Cache Cleaner NG', 'Root Explorer', 'SetCPU' etc that require root access to work correctly.
Enjoy​
2. How to flash the Ultrakiller Recovery Image
Now this has been covered many times but there have been a lot of problems with the BSOD on the IDEOS. A few days ago Ultrakiller came up with a solution that works regardless of the LCD type. Now this was distributed as an IMG file so many people were confused so here is a link to one with everything you need included. All I did was remove the amon'ra image and copied the Ultrakiller recovery IMG to the folder and edited the scripts to point to the new file.
After you download the file:
* Put your device in bootloader mode - turn it off, then press the power button while holding the 'Volume Down' and 'End (Red)' keys (Yes, bootloader is just the IDEOS logo) WHILE YOUR DEVICE IS PLUGGED IN
* WINDOWS - double click 'install-recovery-windows.bat'
* MAC - Open a terminal window to the directory containing the files, and type 'chmod +x install-recovery-mac.sh' followed by './install-recovery-mac.sh'
* LINUX - Open a terminal window to the directory containing the files, and type 'chmod +x install-recovery-linux.sh' followed by './install-recovery-linux.sh'​
See Q3 if you have Windows and the prompt hangs on "Waiting for Device"
3. How to solve problems with drivers on Windows in bootloader mode?
1. Unplug your phone
2. Download and install PDANet from here - at the end of the setup it will tell you to plug in your phone - do that
3. Put the phone into bootloader (See Q2 above)
4. Go to device manager and right click on "Android 1.0" and click "Update drivers"
5. Click "No, not this time" and Next
6. When it asks you where to look for drivers point it to PDANet's install location
7. Hopefully it should find the driver and prompt you to install it - it will take some time
8. You can now access your device in bootloader!​
Thanks to the following people:
Quail for the base of the guide and the ROM I'm using - it's amazing BTW
Ultrakiller for the recovery image
Changelog:
21/01/2010: Initial writeup

i unfortunately deleted a system app and upon restarting my phone it wont boot.....it keeps hanging at the startup and reboots.. help me how to system restore...

Hi - the Ultrakiller recovery IMG in the ZIP from the Link above is "Ultrakiller.img.img". Dunno if it didnt work cause of this - sry didnt test, just downloaded new Ultrakillers "UltraJack-Recovery_v4.6.2.img", saved into that folder and changed the .bat to "fastboot-windows.exe flash recovery UltraJack-Recovery_v4.6.2.img" and it worked for me Even superuser.apk didnt work for usb-root but z4root does it perfect and DroidExplorer showing files now .
Thanks so far to all investing their time here
P.S.: the HUAWEI background of Ultrakillers recovery is very delicious

Dear have u find out the solution of this problem?? COZ im also suffering from this if u find it then plz tell me [email protected]

I have downloaded a rom from xda-developers wiki from this link
http://forum.xda-developers.com/wiki/index.php?title=Huawei_U8150_IDEOS
then updated my device software by going in to update mode(press vol up + end key + power button) .
This step returned me my original recovery.
But I am not going to recommend it bcoz i am facing problems like my cd drive which is automatically displayed has become inaccessible.
I am having problem to copy files to sd card.
My upgrade mode is not working now.
all these things were working immediately after the above mentioned process but I am now stuck with these things.
I think it is because i have flashed lower version number of rom on phone.
If you want to recover recovery mode only then I have successfully flashed UltraJack-Recovery 5.2.1 from this link
http://forum.xda-developers.com/showthread.php?t=860189&page=24
Inform about your progress

Thanx. Very useful

Hi guys. I am in a lot of trouble with my ideos.
Tried installing a custom ROm using ROM manager and it failed, although the original ROM is still there and its booting up and working perfectly.
However, when i try to boot into recovery, only the lit blackscreen shows.
I have tried everything from running ULTRAjack recovery on windows(which only shows 'waiting for device' on cmd, with the pdanet drivers installed) to ubuntu(which shows 'waiting for device' on Amon-ra recovery and permission denied on ULTRAjack).
Could it be i didnt root the device properly since i used z4 root?
Any more ideas?

900/2100 or 850/1700/1900/2100
Hello, How do I tell which sub-model my U8150 is please? Either HSDPA 900 / 2100 / AWS or HSDPA 850 / 1900 / 2100 / 1700. baseband = 22201003; build no.= U8150V100R001C183B825; IMEC = 355093040562676; IMEC-SV = 39.

Check out your fcc id suffix. I have heard there is a b version and a d version.

This guide is successfully tested by me.
1. You need a 32 bit OS. (I have used 7 Pro x86).
2. Turn USB debugging ‘ON’ in settings of the tablet.
3. Download Superuser. Then extract the zip file to desktop :\ & you will see 2 folders as “System” and “Meta-INF”.
4. Download the drivers from here. Then connect the tablet & install the drivers using device manager.
5. Download SuperOneClick!. Extract the archive, go to the folder named ADB. Open an elevated command prompt there using this.
6. Continue with the following commands:
Code:
>adb root (you will see a message “adb is already running as a root”)
>adb devices (you should see your device number)
>adb shell (adb shell will run and daemon tool will also run) 7. Now restart the tablet & wait till the home screen appears. Now continue with the following commands:
Code:
>adb shell getprop ro.secure (output should be 0)
>adb shell mount -oremount,rw /dev/block/system /system
>adb push d:\system/bin/su /system/bin/
>adb push d:\system/bin/su /system/_install/bin/
>adb shell chmod 4777 /system/bin/su
>adb shell mount -oremount,ro /dev/block/system /system 8. Exit adb, disconnect the tab, restart it again.
9. Open the new Superuser app just once.
10. Download apks of BusyBox, Google Play & Titanium Backup (Google is your friend!!).
11. Install BusyBox first, then check the rooting status with Titanium Backup. After that, install Google Play.

Karbonn A9 adb root (FINAL HOPE)

​
Requirements and rooting process
1 > Your pitiable unrooted Karbonn A9 Android device
2 > ADB drivers for your device installed on your pc (I used WinXP. You may use Win 7/Vista or the Linux distro of your choice)
3 > su , busybox , Superuser.apk
4 > A working linux distro with Nautilus (use a live usb stick of Ubuntu 11.04)
5 > Strength, courage and whatever makes you a man !!!!!
Rooting Process
To start, you must have adb installed on the OS of your choice.
I used my trusty WinXP system .
To confirm your device is properly detected, in the command prompt , run -
CODE -
adb devices
Now copy busybox, su, superuser.apk to /data/local/tmp/ using adb.
CODE -
adb push busybox /data/local/tmp
adb push su /data/local/tmp
adb push Superuser.apk /data/local/tmp
Now run adb shell .
CODE -
adb shell
Note that you see a "$" sign in the command prompt. That means you are not rooted . Next run the following commands in the shell to change permissions and get some limited privileges for the Superuser files:
CODE -
chmod 6755 /data/local/tmp/su
chmod 755 /data/local/tmp/busybox
chmod 644 /data/local/tmp/Superuser.apk
Note that the names of the files are case sensitive.
Done?
Turn off your Android device using the power button.
Now you need to reboot your system into a Linux distro which has Nautilus.
Android and Linux, having a similar heritage, makes it possible for us to get root access over the Android phone if you are running with root privileges within Linux. I used an Ubuntu 11.04 Live USB disk to save the hassle of installing another os.
When you have booted into Linux, open up terminal and type:
CODE -
sudo nautilus
This would open up the Nautilus file browser with root privileges.
Now put your Android device into Download mode . for the karbonn A9 the method is to hold down the Volume up button and simultaneously turn on the phone using the power on switch.
Once in download mode, connect the Android device using the microusb cable to the computer.
Now using the open Nautilus window, navigate to /UserData/local/tmp/ folder and verify that you have the files you sent to the device viz. su, busybox and Superuser.apk
Move/cut-paste su and busybox to /system/bin/ using Nautilus.
Move/cut-paste Superuser.apk to /system/app/ using Nautilus.
Now pull out the battery from your Android device.
Now simply turn on your device.
You must now have root.
Verify by running:
CODE -
adb shell
su
You'll note that the "$" prompt will turn into a "#" and you'll be prompted by a Superuser permission notification on your
device
WOOHOO !!!! YOU NOW HAVE ROOT ON YOUR PHONE !!!!
​

Important -
​1 > For all purposes, consider that your warranty will be void if you follow these steps
2 > I am not responsible for any loss, monetary or otherwise arising as a result of this article.
If you don't feel up to it, quit now and close this web page .
3 > I must assert that although I am aware of no reason why this should not work on *any* Android device, phone or tablet, I have only tested this on my GALAXY s3 .
4 > I have tried to explain it in the easiest way I can, but I must state here that this is by no means an easy task and you must persevere. If you can't follow the steps to the letter, its better you don't follow them at all and wait for a single click app for this or a custom rooted firmware.

[GUIDE] Make your android device True Root! - by Napalm

[GUIDE] Make your android device True Root! - by Napalm​
I did this on my Nexus 7 but it should all still apply to most devices. You might need to follow different driver advice for other devices.
Pre-requirements:
Installation of the SDK platform-tools.
Have platform-tools directory of the SDK in your PATH environment variable (Google this if your unsure).
This was all done a Windows installation, but access to Linux will be required later on. Mac users might be able to get away with doing the Linux portions directly on there computer. Please let me know if your a Mac user and have had success with this and I will update the guide with details.
Step 1: Driver Installation (READ THIS, do not skip)
First I needed to update to the usb_driver from SDK and then modify the installation inf with the IDs for Nexus 7.
Browse to your SDK directory and futher into <SDK>\extras\google\usb_driver
Open android_winusb.inf in your favorite text editor.
Find the appropriate section Google.NTx86 if your on 32bit or Google.NTamd64 if your on 64bit (doesnt matter that your using intel chip). Now find the ";Google Nexus 7" line inside that section and you'll see a series of settings below. Add the following lines at the end of that block.
Code:
%CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_4E44&MI_01
%CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_D001
These are the identifiers for the Nexus 7 recovery and bootloader usb connections.
Step 2: Standard Root
Next you'll need access to the bootloader and recovery mode so follow this guide to unlock and "root" your device. http://forum.xda-developers.com/showthread.php?t=1741395
Here I've laid out the steps I did instead of the above. Remember this wipes your device and its internal memory completely, so backup your data.
All local work is done from the desktop, so when you first open a command prompt or if you close it and reopen it enter the following.
Code:
cd Desktop
Download CWM recovery image to Desktop. http://goo.im/devs/birdman/CWM-grouper-recovery.img
Download SuperSU CWM update zip to Desktop. http://forum.xda-developers.com/showthread.php?t=1538053
Go to Start or Start>Run and type in: cmd
Code:
cd Desktop
fastboot oem unlock
fastboot flash recovery CWM-grouper-recovery.img
adb reboot recovery
Now the device will reboot into recovery mode. If windows asks for drivers for the "new" usb connection direct the wizard to your <SDK>\extras\google\usb_driver. And the earlier modifications made in Step 1 should mean it installs the device and adb link.
Once drivers are installed and every is good go back to the command prompt, and type
Code:
adb devices
It should list your device with the word "recovery" next to it. If it doesn't then your device is not in recovery mode. Now enter in the following commands into the command prompt and it will make your devices CWM installation permanent.
Code:
adb shell
mount /system
cd /system
mv recovery-from-boot.p recovery-from-boot.bak
umount /system
exit
Now to install SuperSU. Tap "reboot system now" on the screen (if you dont see CWM, press the power button to show/hide it). Wait for the reboot. And then enter the following into the command prompt.
Code:
adb push CWM-SuperSU-v0.94.zip /sdcard
adb reboot recovery
Wait for reboot. You should see an image in the center of the screen. You might have to press the power button to toggle the visibility of the CWM menu. If you miss-tap on the screen, the power button acts like a back button and will return you to the previous menu screen.
Tap "install zip from sdcard" and then "choose zip from sdcard". Then select the CWM-SuperSU-v0.94.zip file (You may have to use the vol-up/down keys to highlight this if the file is listed off the bottom of the screen)
Let that install and then go back on the menus and choose "reboot system now".
Now if all is well after the reboot, if you run the following commands in command prompt.
Code:
adb shell
su
SuperSU might now prompt you on your devices screen to accept the root access, and then hopefully your command prompt should end in a # (this means you are root user 0). Now type exit twice to get back to the windows command prompt.
Now if you were to type "adb root" you will notice it tells you adbd is not able to go "full root". This will be solved in the next step. This is going to get complicated. You have been warned.
Step 3: True Rooting!
Now your device is "rooted". This is true, you now have a "su" binary installed and a visible app in the OS to manage super user privileges, but as a developer I want to be able to use things like "hierarchy viewer" on my live device. And have the room to do what I need to debug complex situations. So this is where True Root comes in. This essentially turns the device into a debug device that you would get direct from the manufacturer.
You may be able to get away with doing the following in a different way and you may not need to compile anything since fastboot has a boot flash option, but since I've never used this I've done it this way. If you prefer you can explore things in that direction, but be warned I've not tried it and so I have no idea if it would work.
Now for this step you will need access to a Linux installation. If you've never used Linux before don't be too afraid. But I am going to have to gloss over a few things. If you need further help on this step you will need to post in the topic and allow the community to advise on best pratices.
If you dont have access to a Linux installation or your newb to Linux then go here and follow the steps. It will add Linux to your PCs boot options and then you can go in and out of Linux when you need it. http://www.ubuntu.com/download/help/install-ubuntu-with-windows
Remember if your working on this step from a fresh Linux install like the above then you will probably want to install the android sdk for linux, at least enough to use adb from linux. This topic might help with this: http://forum.xda-developers.com/showthread.php?t=537508
Ok now from Linux follow along. You'll need git installed for this "apt-get install git".
We now need to compile the apps needed to modify our boot image. Details can be found here https://gist.github.com/1087757 but you might just want to follow my specific instructions.
Open a console window and type.
Code:
git clone https://android.googlesource.com/platform/system/core
cd core/libmincrypt
gcc -c *.c -I../include
ar rcs libmincrypt.a *.o
cd ../mkbootimg
gcc mkbootimg.c -o mkbootimg -I../include ../libmincrypt/libmincrypt.a
cd ../cpio
gcc mkbootfs.c -o mkbootfs -I../include
cd ../..
git clone https://github.com/beide/Bootimg-scripts.git
cd Bootimg-scripts
cp ../core/mkbootimg/mkbootimg ./
cp ../core/cpio/mkbootfs ./
Ok that has prapared the a Bootimg-scripts directory with the perl scripts we need and compiled binaries they use. Now make sure you have perl installed "apt-get install perl".
This is where things are going to split and it becomes your best guess as to how to proceed. I will show you the method I used from Windows. But if you have a installation of the SDK in Linux then you should be able to just open a new console and continue from here and ignore the bits I used to transfer files between Linux and Windows.
Back to the command console on Windows. We use adb to identify our boot partition and extract it.
Code:
adb shell cat /proc/partitions
You will now be presented with a list of paritions on your Nexus 7. Each block here for my device is 1K. So I'm looking down the list and I see one thats 8192 blocks, called "mmcblk0p2". Thats 8MB and I'm taking a educated guess that this is the boot partition, and for my Nexus 7 it is. (Note: if anyone has a better way of determining the boot parition please let me know).
Now we need to take a image of the partition. From here on out replace my partition device name in the commands below with yours if it differs.
Code:
adb shell
cat /dev/block/mmcblk0p2 > /sdcard/boot.img
exit
adb pull /sdcard/boot.img
Now if you want to confirm that this is the boot partition you will need to open the image file in your favorite hex editor and confirm the first bytes of the file are "ANDROID!" in ascii.
Now I FTP'd this image file over to my Linux box and into the Bootimg-scripts directory we created previously. If your following these steps from Linux then you should be able to open up the file manager and move the file into the folder.
Now back to Linux. We'll need to modify repack-bootimg.pl with a text editor of your choice. I leave this up to the reader. We need to modify line 19 the system call so that it starts with "./mkbootimg" rather than "mkbootimg". This is so perl fines mkbootimg in the local directory rather than anywhere else.
Now type in the linux console we had open in the Bootimg-scripts directory the following command.
Code:
perl ./unpack-bootimg.pl boot.img
ls -l
You should see boot.img-kernel.gz and boot.img-ramdisk.cpio.gz and a directory boot.img-ramdisk.
Open boot.img-ramdisk/default.prop in your favorite text editor and make the following adjustments.
ro.secure=1 should be edited to ro.secure=0 and ro.debuggable=0 should be ro.debuggable=1 and if you want ro.allow.mock.location can also be changed to 1 if you like.
Now we've made the required changes to our initrd (initial ramdisk) files we need to repack them to put back on the device.
Code:
perl ./repack-bootimg.pl boot.img-kernel.gz boot.img-ramdisk boot-debug.img
You will now have a new file called boot-debug.img. This contains our modified initial ramdisk. It will probably be smaller than the original. This is no concern as the original we copied was an image of the entire disk including the unused areas, where as the new image is only the data we need.
I now FTP'd this file back to my Windows machine, but as before if your doing this from Linux then you can just carry on.
We now need to flash this image file back onto the Nexus 7 replacing our current boot image. To do this we need to put the device into bootloader mode.
Back to your console/command window, and enter in.
Code:
adb reboot bootloader
Windows might want to install drivers and as before direct the wizard to <SDK>\extras\google\usb_driver.
Once your device is in bootloader mode. Go back to the console/command and enter in.
Code:
fastboot flash boot boot-debug.img
fastboot reboot
Now cross your fingers and hopefully you will get the boot loading animation and your device will get back to the Android launcher.
Now finally from your console/command window type in:
Code:
adb root
Hopefully if all is well it should reply with "adbd is already running as root". Now if you type in:
Code:
adb shell getprop ro.debuggable
It should tell you that its set to 1, meaning it is switched on.
Congratulations!! You have now True Rooted your device!.
You can now debug even system level apps, see log messages from all processes and logcat will now resolve all app names. Use Hierarchy Viewer on a live device instead of the horrible emulator. Do absolutely everything with your device that you want.
Happy hacking,

better late than never.....a thorough quide

umount /system
exit
Now to install SuperSU. Tap "reboot system now" on the screen (if you dont see CWM, press the power button to show/hide it). Wait for the reboot. And then enter the following into the command prompt.
Code:
adb push CWM-SuperSU-v0.94.zip /sdcard
adb reboot recovery
Wait for reboot. You should see an image in the center of the screen. You might have to press the power button to toggle the visibility of the CWM menu. If you miss-tap on the screen, the power button acts like a back button and will return you to the previous menu screen.
Tap "install zip from sdcard" and then "choose zip from sdcard". Then select the CWM-SuperSU-v0.94.zip file (You may have to use the vol-up/down keys to highlight this if the file is listed off the bottom of the screen)
Let that install and then go back on the menus and choose "reboot system now".
Now if all is well after the reboot, if you run the following commands in command prompt.
Code:
adb shell
su
SuperSU might now prompt you on your devices screen to accept the root access, and then hopefully your command prompt should end in a # (this means you are root user 0). Now type exit twice to get back to the windows command prompt.
Now if you were to type "adb root" you will notice it tells you adbd is not able to go "full root". This will be solved in the next step. This is going to get complicated. You have been warned.
Step 3: True Rooting!
Now your device is "rooted". This is true, you now have a "su" binary installed and a visible app in the OS to manage super user privileges, but as a developer I want to be able to use things like "hierarchy viewer" on my live device. And have the room to do what I need to debug complex situations. So this is where True Root comes in. This essentially turns the device into a debug device that you would get direct from the manufacturer.
You may be able to get away with doing the following in a different way and you may not need to compile anything since fastboot has a boot flash option, but since I've never used this I've done it this way. If you prefer you can explore things in that direction, but be warned I've not tried it and so I have no idea if it would work.
Now for this step you will need access to a Linux installation. If you've never used Linux before don't be too afraid. But I am going to have to gloss over a few things. If you need further help on this step you will need to post in the topic and allow the community to advise on best pratices.
If you dont have access to a Linux installation or your newb to Linux then go here and follow the steps. It will add Linux to your PCs boot options and then you can go in and out of Linux when you need it. http://www.ubuntu.com/download/help/install-ubuntu-with-windows
Remember if your working on this step from a fresh Linux install like the above then you will probably want to install the android sdk for linux, at least enough to use adb from linux. This topic might help with this: http://forum.xda-developers.com/showthread.php?t=537508
Ok now from Linux follow along. You'll need git installed for this "apt-get install git".
We now need to compile the apps needed to modify our boot image. Details can be found here https://gist.github.com/1087757 but you might just want to follow my specific instructions.
Open a console window and type.
Code:
git clone https://android.googlesource.com/platform/system/core
cd core/libmincrypt
gcc -c *.c -I../include
ar rcs libmincrypt.a *.o
cd ../mkbootimg
gcc mkbootimg.c -o mkbootimg -I../include ../libmincrypt/libmincrypt.a
cd ../cpio
gcc mkbootfs.c -o mkbootfs -I../include
cd ../..
git clone https://github.com/beide/Bootimg-scripts.git
cd Bootimg-scripts
cp ../core/mkbootimg/mkbootimg ./
cp ../core/cpio/mkbootfs ./
Ok that has prapared the a Bootimg-scripts directory with the perl scripts we need and compiled binaries they use. Now make sure you have perl installed "apt-get install perl".
This is where things are going to split and it becomes your best guess as to how to proceed. I will show you the method I used from Windows. But if you have a installation of the SDK in Linux then you should be able to just open a new console and continue from here and ignore the bits I used to transfer files between Linux and Windows.
Back to the command console on Windows. We use adb to identify our boot partition and extract it.
Code:
adb shell cat /proc/partitions
You will now be presented with a list of paritions on your Nexus 7. Each block here for my device is 1K. So I'm looking down the list and I see one thats 8192 blocks, called "mmcblk0p2". Thats 8MB and I'm taking a educated guess that this is the boot partition, and for my Nexus 7 it is. (Note: if anyone has a better way of determining the boot parition please let me know).
Now we need to take a image of the partition. From here on out replace my partition device name in the commands below with yours if it differs.
Code:
adb shell
cat /dev/block/mmcblk0p2 > /sdcard/boot.img
exit
adb pull /sdcard/boot.img
Now if you want to confirm that this is the boot partition you will need to open the image file in your favorite hex editor and confirm the first bytes of the file are "ANDROID!" in ascii.
Now I FTP'd this image file over to my Linux box and into the Bootimg-scripts directory we created previously. If your following these steps from Linux then you should be able to open up the file manager and move the file into the folder.
Now back to Linux. We'll need to modify repack-bootimg.pl with a text editor of your choice. I leave this up to the reader. We need to modify line 19 the system call so that it starts with "./mkbootimg" rather than "mkbootimg". This is so perl fines mkbootimg in the local directory rather than anywhere else.
Now type in the linux console we had open in the Bootimg-scripts directory the following command.
Code:
perl ./unpack-bootimg.pl boot.img
ls -l
You should see boot.img-kernel.gz and boot.img-ramdisk.cpio.gz and a directory boot.img-ramdisk.
Open boot.img-ramdisk/default.prop in your favorite text editor and make the following adjustments.
ro.secure=1 should be edited to ro.secure=0 and ro.debuggable=0 should be ro.debuggable=1 and if you want ro.allow.mock.location can also be changed to 1 if you like.
Now we've made the required changes to our initrd (initial ramdisk) files we need to repack them to put back on the device.
Code:
perl ./repack-bootimg.pl boot.img-kernel.gz boot.img-ramdisk boot-debug.img
You will now have a new file called boot-debug.img. This contains our modified initial ramdisk. It will probably be smaller than the original. This is no concern as the original we copied was an image of the entire disk including the unused areas, where as the new image is only the data we need.
I now FTP'd this file back to my Windows machine, but as before if your doing this from Linux then you can just carry on.
We now need to flash this image file back onto the Nexus 7 replacing our current boot image. To do this we need to put the device into bootloader mode.
Back to your console/command window, and enter in.
Code:
adb reboot bootloader
Windows might want to install drivers and as before direct the wizard to <SDK>\extras\google\usb_driver.
Once your device is in bootloader mode. Go back to the console/command and enter in.
Code:
fastboot flash boot boot-debug.img
fastboot reboot
Now cross your fingers and hopefully you will get the boot loading animation and your device will get back to the Android launcher.
Now finally from your console/command window type in:
Code:
adb root
Hopefully if all is well it should reply with "adbd is already running as root". Now if you type in:
Code:
adb shell getprop ro.debuggable
It should tell you that its set to 1, meaning it is switched on.
Congratulations!! You have now True Rooted your device!.
You can now debug even system level apps, see log messages from all processes and logcat will now resolve all app names. Use Hierarchy Viewer on a live device instead of the horrible emulator. Do absolutely everything with your device that you want.
Happy hacking,
Napalm :good:

That part is only for the Nexus 7, and if you are using a Nexus 7 with custom ROM then this file may not exist. If you are using stock on a Nexus 7 then the only other question is whether you have renamed/moved/deleted it before. Once you
Code:
cd /system
type
Code:
ls -l recovery*
and see if anything is listed.

Where did you find the info for step one?

I worked it out. You can find your VID and PID from your unknown device in Device Manager. You have to right click the device > Properties > Details > Choose Hardware Ids from the list. Since the driver from Google supports the same interfaces for other devices we can assume it works with the Nexus 7. I made the modifications and it works. Below is a full list of IDs if anyone wants them.

Great guide, but why not just post up the new initrd for people that don't want to do this? It looks as if its the same for all devices.

As requested. Attached are the compiled tools and modified scripts used and the original and modified boot partition image files for the Nexus 7 running Android 4.1.2.

If I'm not mistaken, they are the same for wifi and 3g versions?

Same as before.. just an update for Android 4.2.2... as per the previous posts.. no idea if the non-GSM variant has the same boot partition. If anyone can test please post.

Getting a No_Command error
Hi, I am trying to true root Android M on my Nexus 7 2012 Wifi edition. I followed the steps here and was able to create the boot.img with the ro.debuggable=1 and ro.secure=0. however if i flash this boot.img the device boots and gets stuck in a android bot with a Red ! (bang) triangle. and says No command.
Any idea how to get ro.debuggable on for Android M?

Quantum7+/tabtronics (jb 4.1.1) – root

QUANTUM7+/TABTRONICS ( RK3066/JB 4.1.1) – ROOT
Just to share the experience. This is what worked for me...
All the CREDITS and THANKS go to the “digitalhigh” – for the post below (and the guys in the chain..):
http://forum.xda-developers.com/showthread.php?t=2102600
1. Android SDK Manager (used the following versions)
Android SDK Tools - Rev. 21.1
Android SDK Platform Tools - Rev. 16.0.2
2. Modify File (as explained in the original post):
C:\Users\<YOUR-PC-USER>\.android\adb_usb.ini
- add a line:
0x2207​
3. Install USB driver Win 32/64 respectively - they are attached in the original post above.
!Note: ignore PushThese.zip, attached in the original post – not required – as the “adb shell” gets the root on device straight away. Also, the “Superuser.apk” and the “su” in this attached .zip are not compatible with JB 4.1.1, that is installed on the device. The “Busybox” is also already installed on this device. You can download and update this later from “Google Play”... Hence, just do not use this .zip related step.
4. Download “Superuser-3.2-RC3-arm-signed”
Download the following “Superuser-3.2-RC3-arm-signed” package from location:
http://downloads.noshufou.netdna-cdn.com/superuser/Superuser-3.2-RC3-arm-signed.zip
Unzip and copy “Superuser.apk” and “su” to the“adb” directory:
C:\Program Files\Android\android-sdk\platform-tools\
5. Tablet to PC:
“Developer options” → “USB debugging” → [v]
Connect Tablet to PC. Kick off the USB driver installation (if not yet done in Step 3).
From the Win command line:
Code:
cd C:\Program Files\Android\android-sdk\platform-tools\
adb devices
The device should respond as 0123456789ABCDEF, or something similar to this.
6. This is the “Step 15” of the original post with the "busybox" push skipped, just the small changes specific to the device:
Code:
adb shell
# mount -o remount,rw -t rfs /dev/block/st19 /system
# exit
adb push su /system/bin
adb install Superuser.apk
adb shell
[B]# chmod 4755 /system/bin/su[/B]
# mount -o remount,ro -t rfs /dev/block/st19 /system
# exit
adb reboot
7. Once your QUANTUM7+ rebooted you should have the “Superuser” app installed.
8. Install “Terminal Emulator” app from the “Google Play” and try to $ su. You should see the “Superuser” app permissions request etc., etc...
9. Update “Busybox” from the “Google Play” to the latest version.
10. I would suggest you to do the full nandroid backup as soon as you have rooted your device. You can look at this link or details (if interested in):
http://tips4droid.com/make-nandroid-backups-on-android-without-booting-into-recovery/
11. Just one more thing to say – by coupling 2 CPU cores, switching Governors to “interactive”, the I/O Scheduler to “noop” and extending the SD cache buffer to 4096, you device should easily outplay TF201 on the “Quadrant Standard” benchmark test.

Good luck!
