Default Problem with boot loop

Hello.


I got stuk on the firmware update screen after a factory reset that never rebooted (Maybe it's because I'm having a problem with the USB port. Anyway I tried this guide http://forum.xda-developers.com/show....php?t=2663369 for flashing stock jelly bean (I was already in there before the softbrick) and everything went perfect, it rebooted to android, powered back of and got a PASS message at the end, but after I unplugged the phone and powered ON I got the Firmware Update screen again.


Tried another time but I decided to stop the process once it reboot to android, the phone it worked fine as long as I keep it on, if I power it off I will get the damn Firmware Update screen again after I power it ON. Also if I try a factory reset it will reboot to that screen.


Thanks in advance.
