Post [Q] I have some question about backup TA on Z1 locked bootloader 4.3

Hello to everyone on Xda! I'm a C6903 user with 4.3 on 14.2.A.1.136,
I have a problem, i want to backup TA before Unlock bootloader, but for backup i need root, there is a possible way to backup without rooting and after unlocking bootloader?

I need this for a trusted unlock! Thank's to all!!

You can't Backup TA without Root and you can't Backup TA after unlock bootloader because after Unlock you will lost your DRM Keys forever with warranty.

You can Root without Unlock Bootloader so there is no problem at all. Use NUT method.

This is the NUT method, you have to downgrade with Flashtool to .534 provided by NUT to not lose IMEI, Root with Bin4ry Applicartion, then follow the instruction to update to .290. When you will have the .290 Rooted then you are ready to Update to .136 with the same method HERE

Watch the Tutorial Video How To.

This is all for Locked Bootlader.

DONATE TO ME
Downgrade to 534. Root & backup ta. Flash stock 136 and unlock bootloader. Then flash stock adv kernel by doomlord. Install Update superSU and busybox. You will have root 136. That's it.
