But as in process , I saw strange stripes and black screen so I pressed per button to reboot.
After it booted , it was like normal and I didn't see any super user app or any android update , and various apps are telling me that I m not rooted.
Also phone has become so slow (internet) that 1mb app took 10 minutes. Can I root it again ? (Boot loader shows phone unlocked) can phone get bricked if I repeat process again ? And why am I nor rooted?
