[LG Optimus 2x] frikou:
It all went alright but then at 6% the phone turned on itself to the lockscreen and the program asked me to unplug it, remove the battery, put it back on and turn on the phone, I did what the instructions said, I went to Software Update mode by power on pressing vol-, as a result, everything was fine until 80% when it gave me back the same error, so now my phone is kinda of bricked, it just shows a LG logo and then an opened dead android, lol. I'm downloading NVflash, gonna use it for the first time, hopefully everything goes well so I can try the update again.

This is the whole update log:
