Hi,
I need help for my M4 stuck at sony logo and i have tried to repair but in flashmode nothing happen or freeze, it only show the green light all the time when i try to enter the flashmode, same way in flashboot. i can't repair my phone anymore after 5 times repair because my phone always stuck in purple wave. i have tried with flashtool too but nothing happened. I guess this happened because my bluetooth always on and always connect with my smartwatch. I need you guys help me T_T
Thanks
