Sudden death aftermath issues.

[SamDevro]

Sooooooo i experienced the sudden death issue with my Xperia Z, managed to get my phone on again only to have it constanty in safe mode, and my volume down button failing. Presumebly because vol down and power on = safe mode. I ran updates on SUS and PC, the did software repair via PC companion and booted back up. Now nto only am I STILL in safe mode, and my volume down button doesnt work, but my POWER button doesnt fully function either. I can use it as one click to power the screen to unloc my phone but held down it no longer functions to power off the phone and Ive not a clue if it will work to power it on again if It dies from battery drain. I have it charging constantly to ensure it doesnt drain at the moment but I really need some answers. Has anyone else had these problems and how did you fix them?

Did reset vie power on + volume up and has reset, power button fully functional again but still no down volume and constant Safe mode. So in all, software reapir was pretty useless and software updates have made no difference.

most likely there's something stuck on the volume key or perhaps you need to replace them, you should take it to a Sony repair center.

And again turned off and on to re try repair, booting up in normal mode, clicking vol down button acts as if im holding it down, then doesnt work, and power button again unresponsive to hold down.
