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.
