Hi, i have cyanogenmod installed on my xperia z with bootloader unlocked.
before unlocking the bootloader i have used the tool BACKUP TA to save DRM keys
If i want to restore my device to stock rom and restore also the warranty is this the right procedure?
- Relock the bootloader with falshtool
- Flash a sony stock firmware FTF with flashtool and full wipe
- Restore DRM keys with BACKUP TA
Skip first one,flash stock rom and restore TA.
Bootloader will be locked again once you restore TA.

How did you backup your TA ?
The same tool should also have a restore option.
Whatever rooted firmware you are in...you can always restore TA. But once if you restore a TA of locked bootloader. You cant boot into CM based roms. Or any other stock based ROMS with different kernel. As locked bootloader = Stock Sony Kernel ONLY!
So once if you restored the TA and rebooted and your phone doesnt boot but gives a orange/red LED blink. Dont worry. Flash your FTF and then boot to the official stock rom.
P.S : You can also flash a FTF on unlocked Bootloader.
So now first off all I will flash a .ftf file say eg .757 and once the phone boot up I will restore my TA partition and now BT is locked ryt? Any video how to restore TA backup??
Sorry for so much trouble...
