How to force a factory reset or hard reset on Tengda devices

Force restore, also called “hard reset” of an Tengda brand device is necessary when the device does not turn on, shows an error or does not respond and it is not possible to reset it from the device settings.

Keep in mind that force restoring an Tengda device will erase everything on it and you need to know the passkey to be able to turn it back on even after force restoring.
