The battery of my SP was totally empty and the phone was shut down, so I charged it. But while charging, when its got enough power, it turns on automatically, only to shut down again at the moment its on. What to do??
I would try if have the chance, with another battery as suggested above. If this doesn´t help, contact your Local Sony support for information about how to proceed with this in the best possible way:
Ok, please try first run a backup of the device information as explained here. Then perform a system repair using PC Companion or Bridge for MAC. This will factory reset your phone and erase all data. You might need to charge your device for about 1-2 hours before so the device has at least 80% battery. Make sure the device is not connected to computer or laptop and turned off until you are prompted (sometimes you have to press power button and volume up until the device vibrates 3 times or on some devices you have to press the small button near the SIM tray or on the back of the device). Start PC Companion -> Support zone -> Update my phone/tablet -> Blue Repair my phone/tablet -> follow instructions. When prompted connect your phone still switched off holding volume down or back button. The repair or reformat process will start. If you are using Windows 8/8.1 or a 64 bit operating system adjust settings for PC Companion and run in compatibility mode -> chose Windows 7 or XP. Please, keep us updated.
The problem is that it is not charging, because at any moment that is has enough battery, it will turn on automatically, and then turns off again due to a low battery...
