I can get to the recovery menu without any problems, but when I close it, screen just turns black and nothing happens. If I try simulated batery pull it just boots up SONY logo from where I can get back to recovery menu. I also tried to get my phone to fastboot or flashmode but my PC doesn't regoionize it.
I have no idea what is wrong. Installation was smooth and I was already doing the same thing but with Android version 4.1.
Is there any posibility to restore karnel from recovery or any other solution.
