sony Xperia z keeps shutting down

some1one1 — Sat, 02 Apr 2016 16:47:00 GMT

so my phone is having a pretty unusual problem..
it was suddenly shutting down from time to time when opening apps etc.

yesterday, doing an update, when it finished optimizing applications , it shut down after some seconds
I opened it up again , did the updates again ,got the welcome screen and shut down again after a few seconds

I did this again and again with no luck, then i did hard reset through pc companion

Now when it opens it goes on with the same optimizing android applications and when it finishes it shuts down problem

ANY advice , greatly appreciated

@some1one1

Do you experience the same without the SIM and SD cards?

if you do, repair the phone with PCC

PC Companion (PCC)

Bridge (for Mac)

Xperia Companion (XC)

sony Xperia z5 keeps shutting down

My Xperia z5 keep shutting down after a few seconds. At first i tought the battery was too low to turn on. And i charged the phone for a few hours. Then the phone got into a loop after the screen of Sony / Xperia. I tried to press power button along with volume up. And it alowed the phone to start. But after a few seconds and when the phone looked like it will work it shut down and vibrates 3 times.

I already tried a repair with Xperia Companion and while i tought it might work after the process completed it failed again. What should i do?

Thep phone is still in warranty!

Hi, my Sony Xperia Z c6603 began to turn itself off about 3 days yet. At first I could always just put it on again, but than it started to happen more and more and now I'm not able of turning it on again unless it's charging. When I remove the charger it turns off again. Can someone please help? .......
