Xperia Z2 Start-up Problem. I'm desperate - need help!

[AndersJ]

My phone randomly shut down today with full power on, just lying on my table. I had troubles turning it on, did the restart-thingy and finally i got some power in it. The problem is, that after it says ''Sony'' Then ''Xperia'' The purple/blue animated background comes on (as it always does when its starting up) but its stucked in that animation. Have tried literally ANYTHING i could come up with, and what I'v read on the internet.

I couldn't find anything specific about the problem, since I don't know if I'm the only one ever tried so. I'v been waiting for an hour, the animation is still just there, aint turning on completly, waited 5 hours, tried again - same story. holded the powerbutton + volume button etc. nothing works.

I can turn the phone ''off'' when the animation is on, and when i start it again it's still stucked in the purple animation.

Anyone got any suggestion for this?

My thought is, that its some kind of software bug or so. 

I'm REALLY desperate for help

(The phone haven't been dropped or anything, just suddently happend)

Try to perform a system repair and if that fails contact Xperia care http://www.sonymobile.com/global-en/support/contact-us/

Switch off your phone and unplug from Pc (Hold volume up and power for around 10 seconds)

Start PC Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the onscreen instructions - When prompted connect your phone still switched off holding volume down or back button - This should start the repair or reformat process

If you are using Windows 8/8.1 or a 64bit operating system then adjust the settings for PC Companion and run in compatibility mode and chose Windows 7 or XP
