[Xperia Z Q&A, Help & Troubleshooting] schastang:
Hi!

I have a big problem with my phone. I tried to restore a TWRP backup but it failed to complete.

Error occured few seconds after restoring (can't tell what part of the backup was successfuly restored, TA, SYSTEM, KERNEL...).

Now I cannot flash any FTF file. My phone starts with SONY logo but doesn't go further. Screen goes black (backlight) during few seconds and then automatically reboots.

I tried to flash different FTF with different Flashtool but no luck, always got the same error in flashtool :

Notice that debug mode is off (I guess) and my phone is locked (probably during the restore of my uncomplete backup)

Please advise me on how to make my phone start again (find a way to flash stock FTF or TWRP so I can restore another backup, ...)

Thanks a lot.
