[Q] Flashing error - locked out

Hi

I have a X8 E15a (11W52) that has pattern lock. Since this device doesn't have a recovery mode and the usb debugging isn't enabled I haven't be able to remove the patter lock.

So I decided to flash it. Sony PC Companion says that there's no updates available and I get an error with Flashtool.

I get the same error with different firmwares.
