I did a Factory Reset after the JB OTA and lost root. Any easy known way to reroot de device?

How to root XT925 on Jelly Bean OTA (4.1.2) ?
- Thread starter steiger
- Start date
Just checked, the su binary is still there, but when I type su in the terminal emulator I get Permission denied.
None of the root apps are working.
Any way to fix this?

This doesn't work because you need root to change the file permissions.
After a lot of flashing and reflashing, bricking and unbricking the phone, I managed to get Jelly Bean with root.
What finally worked:
-> Used matt's tool to restore phone to ICS
-> Made factory reset and hard factory reset (from recovery menu)
-> Flashed Brazil Retail ROM
-> Used matt's tool to root
-> Installed OTA Rootkeeper, made su backup and unrooted.
-> Applied JB OTA
-> Restored backup in OTA Rootkeeper

You have use the utility droid from matt normally for the xt926 ? What phone you have the xt925 or 926
No! I have the XT925 (GSM version). I don't know if it would work on XT926.

Hi could you direct me to Matt's tool that allows to revert an xt925 to ics please, I can't seem to find a version that works for my xt925.
Thanks.
But do I need to unlock the boot loader? I have this situation, but my bootloader is locked... Can I use this method in my situation? Thanks in advance...
EDIT: I solved it. I could just flash ICS 4.0.4 back after the OTA upgrade! Nice!!!

Can you provide the link to Matt's tool? I'm not sure which one to get and some of them say not to be used with XT925. Also where did you get the Brazil Retail Rom?
Did you unlock your boot loader or were you able to flash without unlocking the boot loader? How did you flash back?
I didnt need to unlock bootloader. Mine is locked until today. I downloaded the firmware ics retail brazil and flashed using rsd. Very simple, indeed. To try another roms, you can install safestrap and then you dont need to unlock your bootloader. =)
Get Root on JB 4.1.2
I get it from another thread no credits to me.
IF You have CWM use the attached file to get ROOT access to JB 4.1.2

If the SU binary is still there...
I found that Matt's Root restore script finished the process and got back root. This is NOT Matt's utility, but a separate script, just for recovering root.
You can find a link to it in the post I made in a different thread. http://forum.xda-developers.com/showpost.php?p=37656547&postcount=136
I have not unlocked my boot loader and using the CWM method of rooting requires that. I wasn't ready to void my warranty nor was I willing to give up trying to get root back.
Give it a try and let me know if it works for you.
Some forum members tried to keep root through the OTA update and used the OTARootKeeper which didn't work all the time as intended. Some of use were sort of 1/2 re-rooted with the SU binary on the system but no root.

Yes - sort of, it will work
I have a 925 (UK) running 4.1.2, which had the tether issue.
So,
I unlocked bootloader
ran the Matts tool to revert back to ICS ( yes it is a verizon tool.)
this reinstalled ICS, however it also broke the modem, so I had no signal / red triangle
then used another tool, whilst in fastboot mode, to install a French Vodafone rom, and did the OTA
to 4.1.2
now my tether works -though no root.

Don't loose root after OTA 4.1.2 JB
To all of you who loose root and stay 'half' rooted after OTA, it's because you are missing a small detail.
1. Right after you root, go to play store and update tour super su APP.
2. After you update the super user APP, open it and update it's binaries. Only after these 2 updates you can install rootkeeper and backup the root and then unroot.
3. Finally, accept the OTA and after JB is installed you open rootkeeper and restore root.
Cheers!
