Unroot R-Box (Android 4.2.2 device) I've bought an Android TV-Box from ebay - it's called R-BOX. I got the device with Android 4.2.2 and root access. However I don't want root. I tried to reset the system and remove root with SuperSU. None of it worked. The vendor software version is RK3066_R-BOX_ANDROID4.2.2-SDK_V1.0.0_130308.
You could install Titanium Backup and freeze the SuperSU app which provides root access on your device. I wouldn't recommend uninstalling it if you don't know how to get it back.
