Re: My Sony Xperia Z won't start /turn on after failed update attempt

A similar problem to the other posters, my Sony Xperia Z won't start after a failed update attempt.

 

Following the support suggestions on the Sony website (http://www.sonymobile.com/sg/support/faq/w8-walkman-phone/update-software/software-update-failed-ps1... failed.

 

Solutions posted on this forum thread (http://talk.sonymobile.com/t5/Xperia-Z-ZL-ZR/My-Sony-Xperia-Z-won-t-start-turn-on-after-failed-updat... have also failed.

 

When I plug the phone into the wall charger, the LED comes on red, the SONY logo appears on my screen, followed by a message indicating that "The Software update failed. Make sure that your phone is connected to the computer and try again.", and then the phone turns itself off. The cycle repeats itself with no indication that my phone's actually being charged.

 

Since it is unable to charge, plugging the phone into my computer does not trigger the update process to start, so I can't "try again", as the message so helpfully suggests.

 

The computer also does not recognise my phone as being connected despite following the PC Companion's instructions to 1) unplug the device, 2) remove and replace the battery (which I can't do, because the battery is built in), and 3) turn it back on (which, again, I can't do, because the phone won't charge in the first place), before 4) plugging it back into the computer.

 

Please help... Thank you.

Re: My Sony Xperia Z won't start /turn on, reboots, freezing and screen is not responsive

Because of some reason, my Sony Z started to rebooting until the battery died. I've tried to reset it by pressing power and vol up. no use..

Power button+vol up until the phone vibrates 3 times.It should turn it off.Try to remove the SIM also.
