Hey guys, I've searched the internet for all possible solutions but couldnt find a specific solution that could help me with my problem. My problem is the following: I rooted my phone a while a go in order to recover some deleted pictures. Now I tried to unroot it again and followed this guide http://www.androidauthority.com/how-to-unroot-android-phone-tablet-652905/. So I downloaded ES file explorer and deleted su and superuser (didnt delete busybox since i couldnt find it) I restarted the phone and it got stuck on the rebooting black and white Samsung screen. I tried to set it back to factory settings but didnt help. Also delted cache and tried to boot it in safe mode, nothing helped. So does anyone know how to fix this problem?
