Continuous Restart and Optimizing Apps

[vif]

Officially updated to Android Lollipop 5.1.1 last week.

Been in good condition until I restarted the phone today.

Now, whenever it's powered up, it optimizes apps, and restarts after optimizing is finished, without reaching lockscreen. I leave it like that for 3 hours hoping it will solve itself, but it just keeps on restarting and optimizing repeatedly.

Have to switch off by the button beside the sim card slot.

Tried to fix it with SonyPC Companion but it's not detected when connected to laptop.

Your help is truly appreciated.

I am using xperia zl. When I was using it, it suddenly turned off and did not restarted again. On external power supply, it started and started doing optimising apps. I made factory reset and also tapped nova button situated near the sim. 

Now my phone has stopped optimising apps but a new problem has started.

It is starting only using external power. It remains swithed on if screen is of. If I turn on the dispay, it gets turn off in around 1-2 minutes of usage.

When I got to service centre for software repair, they told to do on my own risk that the phone can become dead.

Please help me what I can do. Your support will be highly appreciated.

Hi,

I have the same problem, tried everything listed here, even changed the battery and it's worse. Isn't there any "real solution"? In my opinion it's a software problem, cause the problem appeared right after a software update.

Any advice is more than welcome, this bug has been driving me crazy for some time now.

Thanks.
