OK. Finally I flashed prerooted rom by Thibou.
I boot into recovery through Xperia Xposed only. No other option was working.
It was safe or not, I dont know.
Anyway working perfect as of now. Future dont know.
I dare to do this, because you devs are there for any big problem.
Thanks to you and Thibou for hard work & such a fantastic prerooted rom.
Mate. Can you guide me?
I'm currently on CM11 and I want to flash and see if stock ROM works better for me than CM11, for testing sake and also 'cuz I miss the camera terribly.
Should I follow the instructions in the OP, or is there another long method? I don't want to brick my phone so a li'l guidance could do me.
Thanks en avance.
