[Sony Cross-Device General] Linkinsoldier:
but how is this possible? I used the very same file for my old z3 compact without problems and this is a replacement unit (also z3compact!). BTW: Same issue on Win7 PC, so it doesnt seem to be driver or Win related :(

good and bad news.. I now was able to flash the device with the ftf file with the newest flashtool - however I am now stuck in a bootloop!

why does it say ": Writing TA unit 00002774. Value : [01]". I did not set to write anything to TA unit. How do I fix this?

edit: Device was restored with PC Companion. How do I keep this from happening the next time? what did I do wrong?
