Easy Solution to Kingo Unrooting Found
I contacted Kingo about a week ago and gave them a decent donation along with my question. Unfortunately I never got any response back whatsoever. I’m thinking that they are really busy. So, I went ahead and took the leap and did the work successfully myself.
1. I uninstalled Xposed Installer through its own uninstaller. Then I removed it along with Titanium Backup, and the Pro version through CleanMaster with no problems.
2. I was able to uninstall SuperSU through it’s own “Uninstall” feature, then rebooted.
3. The first thing I noticed was the “Custom” and Padlock logo still on my screen at bootup, but the great thing was that I booted up without any problems.
4. I had discovered that the SuperSu Pro apk was still present through the phone’s Application Manager and was able to uninstall it from there.
5. Finally and fearfully, I rebooted one more time.
Everything booted normally again, and this time, the “Custom” logo and padlock were finally gone! I checked the Knox counter and both flags showed 0 x 0. Kingo had a problem with their servers in early February and I tried to root about 15 times over a period of about ten days or so. Suddenly one evening, I was able to successfully root within 3 or 4 minutes, and it really was a one click ordeal. Just be aware that you may not be able to unroot with their program. Don’t fear. Unrooting manually the way I did reveals absolutely no traces of a previous root or that the phone had been tampered with. I’m not sure that anyone who has flashed a custom ROM or recovery would have the same results though, so proceed with caution.
