Solution: please check if the device is getting enough power. Some
TV’s USB ports do not
provide enough power for the device to function correctly. You should try using the included
USB mains power supply.
Also if an external HDD is connected this can cause excessive power drain. Please plug the
additional power supply for external HDD or use a powered USB hub.
Problem: Cannot start device.
Solution: Please download the FW Recovery file from the Rikomagic official website:
www.rikomagic.com to refresh the device FW. Make sure any important data has been
backed up before you proceed with the recovery. If the issue cannot be solved by performing
a recovery then please contact the distributor which you bought the device from and they will
be able to advise the next steps to take.

There may come a time when you need to recover the original firmware supplied on the

experimental nature of these mini ARM computers we have tried to make it as easy as
possible to perform a firmware recovery/installation.
