[Q] Lenovo P780 Powerbutton does not work

myscht · Feb 4, 2014

I flashed my Lenovo P780 with the new ROM. On reboot in teh bottom left corner it said something about about dll not found. After I shut it down again I could not start it up any more (just blank screen).

But when I plug the phone on USB it does start charging (LED is lighting up) and the PC makes the sound associated with an external harddrive being plugged in.

Is my phone bricked? Or is there any chance I can revive it?

Press the red reset button underneath the phone, connect your phone to PC, wait a while and your PC should be able to detect it. As soon as it has connected, start flash back official stock ROM via SP Flash Tool.

This happens to me also in STOCK rom :/

I CAN NEVER RESTART MY PHONE WITHOUT DOING THIS NEXT PART

Anyway here's how to handle it

Press the reset button for 3-5 seconds
wait around 2-5 minutes - DO NOT POWER ON!
now power on, everything should be working, crappy lenovo software (but really good HW :/ ) , Certainly, I'll know now to stay away from them.
