Answer to: Won't turn on or charge, recognises on pc.Hi, My phone did the exact same thing. Was working perfectly and then nothing. I tried the volume button, home button, power button thing and it did not work. I took it to a T Mobile corporate store and they pronounced it old, outdated and in need of replacement. I had no choice, I have no other phone so I was going to buy a phone. She took my drivers licenses and I was getting ready to buy. As I was waiting, I kept holding the buttons and amazingly it came back to life. Works fine. A different forum suggested holding them for 15 seconds, another 30 seconds. I held mine for more like 2 minutes so don't give up and perhaps it just needs a car ride to a cellular store.
