My Vega Iron suddenly restart and encountered this error "System Restart because of Application Error". The first time, it restarted just fine but on the second one it always stucked at L+ Logo. I already tried factory reset on the stock recovery but it didn't solved it. I also tried the Vega Self Upgrade but always have an error on USB Driver on 3 PCs I used. I can't find any help on the net on how to properly run it. Then I tried to flash a latest firmware but with sms fix using CWM Recovery but still encounter same error. I actually found a vietnamese forum with the error but I can't understand even if I translate it.

Can anyone please help me? Current firmware is S1235210.
