mobile

Alright so here we go. Yesterday I was in math class and I turned off my Galaxy S5 before I took a test. That turned out to be the worst decision ever. I turned my phone back on and the wi-fi just continued to say "turning on".

I attempted to unroot my phone using odin thinking that the root was the source of the problem. Whenever I go to a root checker app it says that my phone is not rooted, but SuperSU is still installed and I can't even get the app itself open to check it out.

I am a noob, please use english and I appreciate any attempt of help. Thanks!
