Root 2.3.6 Roms

---

Good news everyone!
Here is the rooting method for 2.3.6 ROM's, that I decided to call PreinstalameEsta (roughly translated to PreinstallThis)

This method doesn't change any user data. The sbf that is flashed during the procedure only modifies the /preinstall partition (CG66), in which exists a security problem that I exploited to get the root access.

Files needed:

PreinstalameEsta's Files: https://github.com/downloads/nicofff...4-gce4da6b.zip

ADB, RSD lite, drivers, etc.

Procedure:

1) Unzip the PreinstalameEsta's Files
2) Plug your phone, and switch on USB debugging
3) Run the rootMM2_en.bat file (or runme_en.sh on linux)
3) When asked to flash the new sbf file, reboot the phone into bootloader mode (turn on while pressing the up arrow on the keyboard)
4) Open RSD lite, select the fixed.sbf file and flash it into the phone. (if on linux, use the sbf_flash app included)
5) When it finishes flashing, and reboots, continue executing the rootMM2.bat file.
6) After a few reboots more, the batch file will finish and the phone should be rooted.

Happy Rooting

Update 05/08/2012:

I got my phone stolen last night (In San Telmo, Buenos Aires). Just in case it ends in the hands of a good soul and they happen to come here, i humbly ask them to return it.
The way to identify it: Under the battery, there is a sticker from AFIP that is slightly burnt.
Thanks

Yes it does! 300 Downloads from GrupoAndroid and counting!

I flashed fixed.sbf with rsdlite, everything was fine... after that when I tried to use the root_mm2_en, it was saying that couldn't change, like other roots (doomlord v4, superoneclick,...)

What can I do ? Later I'll post my error


Thanks a lot !

gb vivo 2.3.6 & windows 7

when i run rootMM2-en.bat it opens a window where there is written " press a button to continue" when i press it, it start to work and appers this message :

0 KB/s (105 bytes in 1.000s)
Without closing this window, shutdown the phone
and restart it in bootloader mode (power + UP key in the keyboard)
Once inside the bootloader mode, flash the fixed.sbf from rsdlite
after it restarts, enable USB debugging and press enter to continue...
Premere un tasto per continuare . . .
Waiting for Phone
Syntax error: Unterminated quoted string

than the phone switch off by itself and i had turn it on in bootloader mode, i have flashed the fixed sbf and than the it show me this message

It's a bug because of the translation... I've found it:

adb shell "echo 'doing something on adb, otherwise it doesn't work'"

Should change to

adb shell "echo 'doing something on adb, otherwise it does not work'"

@nicofff the ' in "don't" caused a syntax error

do this:
adb shell "rm /data/preinstall_md5/*"
and then run the script again, but when instead of rebooting into bootloader mode and flashing, just reboot it normally
