Shutdown loop

Romaha — Tue, 25 Mar 2014 04:11:18 GMT

I upgrade my Z1 to 4.4.2 and get the next issue.

When I switch off my phone with long press power button -> "swich off phone", its successfully shutting down but after 5-10 sec. show startup SONY logo then swich off display then show logo again and so on endlessly...

It was very unexpectedly, when I swich off Z1 and put it into pocket, after cuple of days I found it totally discharged. I cant make phone alive with wall charger and only 2-3 hours on USB charger can reanimate Z1.

Is there software problem with shutdown loop or problem with battery controller or something else? How can I fix it? Any considerations?

P.S. Small "force shutdown" button or Power+VolUp combination sometimes help to shutdown phone.

I find the solution!

After villions of reflashing, rebooting and so on....

1. Enable "Developer options"

2. Check "don't keep activities" menu item

2. Normal turn off phone with hardware Power button

Tadam!! Its shuted down normally.

3. Torn on and uncheck "don't keep activities"

I have no ideas why that was help me, maybe its srteet magic
