Then today I wanted to experiment with xposed framework but realized that I didn't have a recovery when I tried to make a backup. So first I tried installing TWRP through Goomanager but for some reason it would fail after the download. So I decided to install CWM touch trough fastboot. So I installed it and then did a backup. The problem came when I tried to exit. A message appeared and it said "ROM may flash stock recovery on boot. Fix?". I pressed yes, and then it told me something like "Root may have been lost. Try to get it back?" and pressed yes again. I rebooted and thats when supersu dissapear.
I panicked and tried to do the same procedure fro the guide again to get root. I repeated every single step but it wasn't succesful. I thought that maybe CWM was causing the problem so I installed TWRP trough fastboot and did the root process one more time. But again supersu just wouldn't appear back.
I really don't know what else to do. Everything in the stock ROM works fine but I just can't root my phone again. Does anyone know what I can do?
