Due to incompatibilities with some apps, I need to roll back Android 7.0 on my new RCA Voyager Pro tablet to the original version shipped with the tablet, Android 6. When I first started the tablet, it automatically upgraded the firmware to Android 7.0. Will the Android version roll back from Ver 7 to Ver 6 with a full factory reset, i.e. "Power off, hold vol up, hit power key, select from menu", etc
