Hello Everyone! I have to send my phone back and get a replacement because my back light is out. I literally cannot see anything unless I hold it up to a lamp. I dont know if they will ask for my old one back but I assume they will and I dont want my root to complicate things. I have managed to figure out that I can get too fastboot but nothing else. I haven't been following for a while so what would be the best way for me to restore my phone too stock?
