[Xperia Z1 Q&A, Help & Troubleshooting] Lebkuchenmann:
Hello everybody,

I just tried to flash a stock firmware to my Xperia Z1, because I kinda got tired of Pacman and wanted to try out Android L.

I downloaded Flashtool, installed the drivers, downloaded the rom and hit the flash button. Everything seemed to workout just fine, but somehow the flashing process got stuck at "Processing fotakernel.sin".

I tried different versions of flashtool, but nothing helped. I tried another ROM but it got stuck a few more steps before at "Processing rpm.sin".

Atm I'm using the 0.9.14.0 version, which worked out for me ever since.

Here are the informations Flashtool has given me so far:
