Fault from customer:network problem
Customer reason:when slide down network falls.
My prediction for fault:flex cable damage

Present status:when pressing power switch blank white screen
appears for 30 sec then phone switches off.
Tried solution :1.already three flex
2.removed the flex and flashed the phone now getting
error when at the beging of erasing in griffin.
