Update to 47..2.A.4.45 killed my phone

[EmilFuncke]

(I also posted this in the forum for the XZ1)

I got a notification to download the latest system update to my phone (XZ1 compact). I did so and the download and installation continued as usual. 

Now when the installation is complete it seems Android isn't responding. 

When I start my phone and unlock it I can se a part of the homescreen where I usually see a couple of apps and widgets. And a text with a rolling bar that says Mobile starting (its in swedish so I do not know what it would say in another language). 

I can swipe down on the screen and get to the settings menu. And I can recieve calls. But I cant get to any of my apps and when I recieve calls I can see the number that is calling but not the contact. 

I have tried to restart in safe mode, I have tried to restart the usual way several times. 

What can I do? Its been rolling for hours and nothing have happended. Can I somehow reset to the previous version? I am a total n00b when it comes to these kind of things. Please help.

I would suggest downloading the Xperia Companion- software to your computer and trying its "software repair" option.

I'm sorry to hear you have these troubles, but it seems that something went wrong with the update. The system files might be damaged and the best way to repair it is with a software repair via Xperia Companion.
Ask your neighbor or a friend if you can please use his computer, install Xperia PC Companion and use the internet connection to repair your phone.

You could also try to remove the SD card and go to SETTINGS --> SYSTEM --> RESET to Factory Reset and see if this helps. Your data on the phone will be lost, however...but I assume it already is after the failed update.

I did a hard reset. So now it works (with the new android). Most of my personal information was saved on the cloud so I didn't loose that much. Thank you for the quick help.
