Odin3 v3.09 UNROOT Fail! (Auth)
Hey guys. I got my S5 less than a month ago and promptly rooted it. Today I've been having issues with the phone. It starts up but the screen doesn't turn on. I have to take out the battery and restart many times before it works and then any pressure put on the phone causes it to shut off. It hasn't been damaged physically in any way but I have to take it back to the store, so I believe I need to unroot to keep my warranty intact.
I've been using a S5 firmware I found on this forum and trying to unroot the phone, but I get this string of errors. What can I do? I'm really in over my head here. Any suggestions are welcome.
