Hoping someone can help. I bought a second hand Z2 as a backup phone and it kept turning off. Tried the 2 minute reset with the red button and it won't turn back on. when I plug it in to charge, it only charges for a split second, over and over again. when I use the magnetic charger, the sony logo flashes for the split second over and over again, but when I use USB charger the red light goes on and then off again over and over. I tried using the PC companion and it recognises the phone but says it's locked (indicating that it's turned on - which I don't think it is). I tried the software repair method through PC companion but that doesn't work because you have to turn the phone off. I did the volume up and power button thing but nothing happens when it's not on the charger. When it is on the charger though, it vibrates 3 times like it's supposed to. So, I plug it back in to the PC companion - same thing - it keeps turning on and off over and over again, so it's not "turned off". finally, tried the volume down and plug in - same problem, so nothing works to be able to check for errors. It's only a spare phone, but so annoying. I think I have to put it in to get looked at, but before I do, I thought I'd see if anyone else had any thoughts. I've searched and searched and no-one seems to have had my exact problem - only various parts of it, so no luck finding a solution thus far. thanks in advance
