To reset all Settings on your Player, you need to delete a file from its SD card. This will force the system to apply the default settings.
⚠️IMPORTANT
Remember that if your Player requires some special network configuration to get online, you will lose Internet connectivity. This might render the Player unreachable, and you might go on-site and perform manual configuration.
For Regular Users
Power off your Player (by removing the power cable).
Remove the microSD card from your Player.
You can access the microSD card with your PC. You might need a microSD-to-SD card adapter or a USB memory card reader.
You will see one or more storage filesystems. The first one (the smallest, with around 100MB of space) contains a file called "SETTINGS.txt."
Delete the "SETTINGS.txt" file.
Remove the microSD card from your PC.
Place the microSD card into your Player.
Power on your Player.
Upon start-up, the Player will apply all default settings to the system. This may take up to 10 minutes, and a reboot might occur.
For Advanced Users
If you have remote (SSH) or local shell access, issue these two commands:
In order to SSH your player follow this guide here.
sudo rm -f /boot/SETTINGS.*
sudo reboot
Upon start-up, the Player will apply all default settings to the system. This may take up to 10 minutes, and a reboot might occur.
