Some times, things don't go as planned and a factory reset needs to be done. Unfortunately, Vilfo does not have a physical factory reset button - and as such the factory reset is a bit more cumbersome than most people are used to.
Method 1 - Vilfo interface

If you still have access to the Vilfo admin interface, you can factory reset Vilfo by going to System and clicking on Factory reset.
Method 2 - Power button
If you use version 1.0.7 and later, you can factory reset using the power button on the front. Simply press the power button three times in quick succession and your Vilfo will factory reset automatically and then reboot.
Method 3 - SSH
SSH is a possibility if you can connect to Vilfo by using an ethernet cable or by connecting to the wireless network.
Windows
Windows users should download Putty. After launching the program, enter 192.168.0.1 as the IP address.
Click on connect
Enter username: root
Enter the password for your admin account to the Vilfo user interface.
Type: reset.sh
Press enter
Type: reboot
Press enter
macOS and Linux
macOS and Linux users need to open a terminal window
Write: ssh root@192.168.0.1
Press enter
Enter username: root
Enter the password for your admin account to the Vilfo user interface.
Type: reset.sh
Press enter
Type: reboot
Press enter
Method 4 - Physical reset
If none of the above work, you'll need to plug in a screen (HDMI) and a keyboard to perform a factory reset.
Type: reset.sh
Press enter
Type: reboot
Press enter
