I didn't like it so I restored my backup. Everything was working fine.
I got a notification that there was an update, so I installed that and after it was going to reboot, my phone booted into recovery(TWRP v.18.104.22.168)
I tried to install the backup again, but it also rebooted into recovery. Same thing happend if I wanted to install CM11 again.
I want to install the stock firmare using Flashtools but my phone doesn't boot into DOWNLOAD mode
If someone could help me out, that would be awesome!
