Here is what I did;
1. I used Triangle Away to reset binary counter.
2. Went on SuperSU to full unroot.
3. Tried to software update ( I know this is stupid.. )
I know the only way to go back to stock rom is by downloading from SamMobile / Samsung-Updates but the download host they're using doesn't allow me to download from it. It will always say "Wrong IP". So I tried finding a way around it but I couldn't. Can anyone download from it for me then reupload it somewhere else or is there a way out from here?
