So the rumors ive heard before was false? There are some people in xda told me that unlocking the bootloader will lose be2 and drm keys? I dont know which thread.. I cant remember it anymore. But im sure its was on xda's forum.

Seems that i'm not lucky today.
I tried to relock my bootloader, process goes ok but now my phone is bricked.
i hope to find a solution but everything i tried until now failed: SUS, PC companion, flashing a new one, ...

Edit: After several attempts, i successfuly flashed a stock ROM and the phone is working again... :good:

can anyone confirm that the Bravia Engine stops working after an unlock, and if it does, does this method makes it work again?
