Hello,

While I m updating my Experia Z Ultra by PC companion, I don't really know what happened but now the device don't start at all I always get a black screen says the software update failed make sure that your phone is connected to the computer & try again. When I connect it to the computer the PC companion doesn't recognize the device. If any one knows how fix this?

Regards

First force a shutdown by holding on/off and vol+ at the same time for 10 seconds and then try charging the phone for a few hours (but don't try starting the phone). Then try performing the software repair.
If that doesn't help, also try another computer/cable.

Sorry to hear that you have issues updating your phone.

First try clearing data for the app called Update Centre under Settings -> Apps -> All and then restart the phone. If this doesn't help, have you tried downloading the update using WiFi?

The same thing happened to my phone, except that I did not connect it to my lapto when i updated it. I used wifi on my mobile phone.

I followed the instructions, and stopped until the fact that if I do it, all the files in the internal memory will be gone. I had not removed my memories and all are placed in the internal memory, it will be a shame to lose every data. Is there any other way to do this?
