Hey i flashed the CM-13 on my GT-N5100. At first, it worked well. I can even installed GApps package and changed the theme. Then i tried to install SuperSU and it asked to install the SU binary. So i installed it using flash recovery. It succeed, but when i tried to reboot the phone, it stucked on the "marshmallow" animation boot. I have tried to wipe data and cache, but those didn't work. Then i tried to re-install the CM-13 package (using flash recovery ofc) but it just showed an error message. What should i do? I'm planning to downgrade the phone back to Kitkat. Would it do? Or is there any other way? Please help. Thanks!
