Solved Finally - I ahve been using my Sony Xperia Z for more that a Year or more and suddenly two days back it stopped after I left it at zero percent battery one night. and then on it was not turning on, no matter how long I was having my phone on charge. I saw many blogs and posts for suggestions. But none worked and finally I thpought to try out the docking station port for charging. But I didnt have a dock station for my phone. 1. So I took an old USB cable I had and cut it open. 2. Took the red and back wire. 3. Connected the red(+) to the upper point and black(-) to the lower charge point just with an insulation tape. 4. After 5-10 mins boom, sony logo came on and the device was back on. 5. Then after 2% conencted my normal charger. 6. All works fine then on. For me hard reset, hard reboot , boot loader mode nothing worked. But this one did. Cheers!!!
