Sleep of Death -Power button Display Issues
I bought a Sony Xperia Z Ultra phone on 9th August through Flipkart (online stores) In India, and upgraded to build number- 14.1.B.1.510 on 30th August. After this upgrade the phone display started going on and off every 10 seconds. Then I power it off, since then I could not restart the phone. The phone is dead!
I have pressed the power botton many times, but it was not fruitful.
The battery was 100%, still I put it on charging, but it is not showing any charge light. I tried to connect to my computer, that too doesnt work.
Is there any way I can power this phone ON again?
I m in Lagos, Nigeria. I have contacted Sony centre, but they confirmed there is no Xperia service centre here.
