Standard factory reset:
Connect to AmbiScreenWiFiLED network and click on Settings tab. Now you can change all settings in all pages as desired. Alternatively, you can open page Security & Update setup, tick “Factory reset” and click n Save & Reboot button.
Just if you forgot your password to AmbiScreenWiFiLED network (hard reset):
Turn off device from power (IMPORTANT: when turning off/unplugging device from power always remove from device jack at connector side of device – that is the side where led connector is located).
Plug power and after 2-3 seconds unplug power (repeat this 3 times). On the next boot factory defaults will be recovered. Use hard reset with caution! It can brick your device if done in wrong manner.
