Only root is required. You don't have to unlock the bootloader.

You can't if you don't have a backup of YOUR TA partition.

And how are you trying to transfer them? I swapped sd and Internal. Link2sd doesn't work for me.

Mount each of the folders in Internal/Android/obb to the sdcard. The large files are saved there.
You can also try unlocking your bootloader or applying the definite reboot-remount fix to get link2sd to work.

Someone just confirmed link2sd works with ext3. Gl2sd works fine for obb, like foldermount.

Of all people Motorola who have been so far most developer unfriendly have now announced that they shall honor warranty for developer unlocked BL phones as well as for folks who had done earlier unlocked their BL.

Can anyone advise what is the timeline for receiving the BL unlock code from Sony? Also since it is my Dad's phone I am not gonna be unlocking the bootloader until warranty expires however to be safe I was thinking of getting and keeping in record the code from Sony in case they decide in near future to stop issuing unlock codes. My question is (if anyone can advise), is the warranty void only if I actually execute the unlock process using the received code or is it void even if I merely request and get the unlock code from Sony??

what do u mean timeline?
they will give the code in a instant u give them ur imei number,..it will be sent to ur email account..
i think warranty only voids after u unlock the bootloader of phone...[receiving code wont void]

Hi, thank you it works, now how about CWM recovery for new firmware?
i can't find it.
thanks before:laugh:
