I try to root my htc one m7, when i install supersu, my phone works fine, it will boot normally, but i cant open the supersu, it will close immediately when i open it. So i found a newer version of the supersu and install it. After i installed it and reboot, my phone went to htc logo screen, after a few seconds, it went black, but it seems the phone is running. I went back to the teamwin recovery project, I forgot what I did which deleted my os, and now when i switch on my phone, i goes to the teamwin recovery project. Is my phone totally dead? help! Sorry im just curious to try to root, but now i dont know what to do...
