Sony Xperia Z will not turn on after 2015 update

[Ned1115]

Hi.

So i recently installed the latest 2015 software update onto my Sony Xperia Z and at one stage, it asked for me to unplug the phone, open the case and remove the battery and put it back on. I tried my best to open it but since it is a waterproof model, it is really hard to open the back of the phone. MY PHONE SOMEHOW GOT MESSED UP AND WOULD NOT TURN BACK ON. No matter what i tried, the phone would not charge or turn on. Please help!

You need to perform a software repair using PC Companion.

Thanks for that. But this will require erasing all photos and videos on my phone. Which i do not want. Is there any other way to repair the phone without deleting my photos and videos?

If you were to use a flashtool, it might still not work properly unless you flash with data removal.

Try the following: power button and volume up at the same time. After this, connect to wall socket, charge for 2 hours and turn it on.

@abdoukiller04 it should turn off. Then you should be able to turn it back on by pressing longer on power button.
