ok one more time.
I HAVE TRIED IT WITHOUT THE JB. I formatted the HDD already and did a system restore, tried fresh system and did a Backup Restore from a pre-JB system and a post-JB. I tried to reinstall 3.41 already. I did not tell Sony about the jb (what am i stupid? no offense intended but its kinda given).
The system got corrupted when i changed from Hermes v1 to Hermes v2 and i accedently started the system with the jb connected but not activated (i did not Switch,Power,Eject). It said Unknown USB Device Connected so i unplugged it and the system froze, after restart it didnt load up and blah blah blah here we are.
its a original 60gb model (made March 07). there is no way im sending this to Sony as they will send me back a Slim model and tell me tough.
