Im surprised to find that my S2 I9100 cant be turned on suddenly. Its running ICS and I didnt do any rooting stuff on it.
I have tried each of the following:
-tried holding the power button normally to get the phone on
-took out the battery and switch another battery, it turns out that its not the battery's problem
-tried the hold "power+home" thing
-tried the hold "vol up+power+home" thing
-removed sim card and try turn on again
But I still cant get it to turn on and the screen is black of course. Also, I hear no sound from it and there is no vibration.
Finally I try to plug it to my PC(win8 x64) with the original USB connection cable supplied when I buy my phone, and I get this instantly(though I still cant turn it on):
Thats all it can do. I still cant turn it on...
I also tried to see if the Kies software can detect my phone, it turns out it cant...
PS.: My phone has been running fine for nearly 1 year since I bought it
Any help will be greatly appreciated
