Well, flashing the phone was succesfull. But now I have no chance to unlock the bootloader after *#*#7378423#*#* it says "Bootloader Unlock: No" on the other hand he donīt accept the USB drivers on the Build 18.3.C.0.37, installed over Android SDK Manager and Sony PC Companion. I become two unknown devices and a connection via MTP so i canīt try it a second time ?? any ideas.

Update: After some trys ... after *#*#7378423#*#* I donīt become information, I only can "Reset Customizacion", so I give it a nother try and Xperia Flashing Tool says

02/038/2014 22:38:54 - INFO - Root Access Allowed
02/040/2014 22:40:29 - INFO - Cannot open bundle. Flash operation canceled

After I have exclude:
