[Motorola Atrix 2] jimbridgman:
Ok, so you want to return to GB from ICS, right?

Well I have written a script for AT&T users to get back to GB 2.3.5 from ICS with the fxz patched with the same patch the Chinese forum had used.

It is very simple just download the correct file there is a version for windows users in a batch file, and a shell script for the Linux and Mac users.

This has been tested and will not brick your phone. We have several confirmed cases that this works Even one of our devs soft bricked on ICS today and was able to get back to 2.3.5 from this.

--UPDATE 10/18/2012--

Do NOT use this if you are on leak 2/the soak/the final OTA!!! You will hard brick!!!

This ONLY works for leak 1, that is dated early July in the build date.

--UPDATE 09/26/2012--

Here are the 2.3.6 fxz scripts as well, that alteredikeness put together when the 2nd leak came out, go thank alteredlikeness for these:

--END UPDATE--

2.3.5 Files:

Windows:

You will download the following zip file:

http://www.androidfilehost.com/main/Motorola_ATRIX_2_Developers/jimbridgman/a2_return_to_gb_win.zip

MD5sum: 85dd75fc711a723837d927c6de6ca1fa

Then unzip the whole thing, do not drag and drop the files, there is an A2_go_back_win directory with all the files in it... extract this directory to either your desktop or C:\ BE VERY CAREFUL YOU DO NOT DRAG JUST THE FILES TO C:\ but you extract the WHOLE directory there.

Then go to your command line (cmd) and cd to either your Desktop or C:\A2_go_back_win then run the restore-to-gb.bat file

C:\ > cd A2_go_back_win
C:\A2_go_back_win > restore-to-gb.bat

Linux and Mac:

You will download the following zip file:

http://www.androidfilehost.com/main/Motorola_ATRIX_2_Developers/jimbridgman/a2_return_to_gb_lm.zip

MD5sum: 58b4c47c02e9ad0a379ca8cc5734687a

Unzip the file and go to the command line and cd to where you unzipped the file to and cd into the A2_go_back directory. Then run the return_to_gb.sh shell script

The following is an example of how to run this. The directory I use is just and example, please cd to the correct directory you extracted the zip to on your machine.

$ cd ~/Downloads/A2_go_back
$ ./restore_to_gb.sh

This will ONLY work if you are on ICS, I will get something for 2.3.6 and 2.3.5 from, once you have been on ICS, those are "special" cases so PLEASE do not attempt that until further notice.

Thanks to the following users:

If I forgot you please PM me, all of those guys deserve for you to hit their thanks button for either testing, or getting the needed files, or other support.

One last thing, if you brick or soft brick I am not responsible, you hacked your phone and made the choice freely, to do so.

Now upward and onward to more android development.
