I have the same issue with mine. Battery went flat but since charging it for hours its now stuck in some sort of boot loop, getting to the logo and then shutting down before starting up again, etc.

I tried the software fix, which said it worked but its still in the same loop. I have removed the SD card also to check its not that and still no luck.

Did you get your issue resolved?

Hi @Tarquind, I'm very sorry to hear this.

If the software repair didn't help I'm afraid your device is in need of repair. You can contact your Local support team for information on how you can proceed with this.

I'm sorry for the inconvenience this causes.

Hello

What would be suggestion about 6 months ago i changed battery in sony service center, was asked 198 € for it - and it now has started randomly charging- sometimes picks up charger and lights tun from red - orange - green sometimes, it is just red. sometimes , when phone is off i try charge - it charges with battery logo appearing, sometimes, it just boot-loops?

Any resolve from Sony side - it's definitely related to phone hardware/battery/software which can not co-excist properly (improperly picked device parts).

After last update 30.2.A.2.1 it wount be picking up charger at all. Only Red light. 

Question is i payd to Sony quite amount of money, but whatfor - no oportunity anymore to downgrade phone to where it somehow worked for me. No opportunity even to try lower version 5.1.1 base stock to see IF it works. Sonycenter masters told me there is no way to rollback Sony phones.
