So I have read multiple articles on how to unroot and have tried 2 of them with no avail. Can anyone explain to me or point me in the right direction on to a "How to unroot for dummies" or something!? I tried getting a nandroid backup and putting in in TWRP/backups/ but for some reason when I boot into recovery and select "Internal Storage" it doesnt show anything! Then I tried to flash the stock recovery from the toolkit and I get an error. Any help would be appreciated.
