Sleep of Death -Power button Display Issues

Support,

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.

please help!

Jay

Did you try to reset it with the red button on micro SIM card slot?

by

Yes, I tried the Hard reset button (inside SIM card tray). but that doesn't work!! even sony service centre stopped answering me!

Hi,

It is the battery.

A friend told me to recharge the phablet plugged into on my computer. That fixed the problem for me.

This is like playing the piano.

We connect the charger (USB)

pressed the button on / off simultaneously with VOL +, the mobile phone after 8 sec. will vibrate once and spent another 5 sec. vibrating three times.

Quickly we dropped just the on / off button and turned off the usb cable, the red LED turns off and the device restarts.

Once the Sony logo appears we dropped the VOL + button and turn off the phone by pressing the on / off button.

Now is the unit off completely.

Now just connect ... and good luck

I experienced similar issue. all I do is just pressing the tiny red button near sim tray and all is done. I use my point butterfly knife (balisong) btw, and I press it for like 8 seconds and voila.

I think you should try to press and hold it.

Hi there, i had the same, phone did not turn on and power led was blinking every 3 secs when i connect charger and didnt turn on :( checked the following:

-pushed mini "hard reset button" beneath the sim card cover didnt work

-pushed vol down and connected usb cable didnt work (should start with android system menu)

Pls do below on your own risk.

-took a heat gun (a hair dryer will work also but more time is consumed). Heat back cover till your palm feels quite hot (but not so hot to prevent touching, dont go that hot). Took a very thin "-" screw driver or guitar pick and opened back cover. Found battery connection and removed connection (not the battery) and waited 10 secs. Replugged battery and connected charger. Phone turned on :) :) :) :) :) pls watch "how to replace sony xperia z ultra battery" video on youtube. It is really easy than expected.

Thanx

I used a small screwdriver to remove the back, removed the water inside and disconnected and reconnected the battery connector and now its charging and fully fixed. THANK YOU SOOOOO MUCH, I was so worried I would have to buy a new one but it now works perfectly!

My friend and I had the same issue as well. I just pressed the rest button near the SIM card slot and the phone vibrated thrice. After that, I pressed the power button and it worked.

good day,

i didnt do below particularly on sony devices but on samsung which i hope helps. (i had killed my samsung because of PC app "samsung kies" while trying to update OS)

-google for sony ROM burning program.

-download ROM from sony forum websites

-install the program and select downloaded ROM on it. It will say "OK" (otherwise you must download another ROM) ROM is abt 600mb

-hold vol up hen connect USB cable.

-program will detect the phone and go ahead burning new rom

it will take about 15 minutes and DONT PLUG USB OUT and dont touch yourphone untill it turn on an home screen comes.

even samsung service they said "your phoneis dead" but i saved my device this way :) :) haha :)

i have no links to thoseprograms and roms :(
