So after rooting my phone and it worked fine, i went to do a back up. I turnd off the phone got to the white screen, went to back up and clicked that, it went through sucessfully. i went to reboot and it went to a black screen and nothing happened. It is stuck at a black screen with a green light blinking on the top. I waited a while then took the battery out. It seemed to boot up fine, i got to where i could interact on my front screen then suddenly shut down and went back to the blinking green light on the top...any help would be great thanks
