Hi,I had to go into recovery and reformat my phone when I tried undoing my root. I'm on CPH2647_15.0.0.701(EX01) and went to system update to CPH2647_15.0.0.822(EX01), but I keep getting an installation problem:Could my previous root be causing this issue? I thought a reformatting of my phone would get rid of my root.Thanks for any help.
