Hi everybody,

I have a unlocked Bootloader with the latest Poison FW.
No I need to send the device back to sony because my back camera don't work anymore.
What have I to do to get a "clean" device with a locked bootloader and a stock fw?
I have relock my Bootloader with the flashtool but now I get the Message "your device has failed verification and will not work probably"
Then the device shut down.

I try to flash the Sony Xperia X(F5121). FW release : 34.3.A.0.252 with the flashtool but it didn't do anything,

solved
I found the solution.
I use the Flashtool emma and flash the new Firmware. After that I relock the bootloader with the Flashtool
Then I use the Xperia companion to install a clean firmware.
