Dead Z5 after full partition restore - Is bootloader bricked?

Hello, I sent my phone to warranty so I could get it repaired. So I backed up with twrp all my partitions (I'm BL Unlocked also). I got it back, flashed twrp, unlocked BL, and restored the full backup. Now I have a phone who won't boot up, even to the Sony logo, to fastboot, recovery or even flashmode. A 2-min reboot didn't helped. If I plug it in any power source, the red led blinks one time for half a second every 5-10 seconds.

Any way to reset the bootloader to default, as a wrong partitioning / restore damaged it ?

Is this a good question?

Also, while flashing the backup, I flashed TA. As the serial numbers are different between the unit I had before warranty and after.

Yeah. Sent it back to Sony. In fact, the serial n° changed from before the repair, and after. They should have told it to me, if I knew it, I would not flash my own backup as a nandroid
