If you encounter the "Setup Wizard has stopped" error after a factory reset on your RCA Viking Pro tablet, try the following steps to resolve the issue:
1. Restart the tablet: Power off the tablet and then turn it back on. Sometimes, a simple restart can fix minor software glitches.
2. Clear cache and data: Go to Settings > Apps > All Apps > Setup Wizard. Select "Clear cache" and "Clear data" to reset the Setup Wizard settings.
3. Check for software updates: Ensure your tablet has the latest software updates installed. Go to Settings > System > System updates and check for any available updates.
4. Perform a hard reset: If the issue persists, perform a hard reset by holding down the power button and the volume up button simultaneously until the tablet restarts.
If none of these steps work, consider contacting RCA support or seeking help from a professional technician.
