Upgrading Over the Air (OTA)

If your device has access to the internet you can update UnofficialOS directly from EmulationStation.

1. In EmulationStation open the main menu by pressing the "Start" button on your controller.

Upgrading Manually

If you device does not have access to the internet you can still update manually

   • If you have any questions you can check the Device Support section to confirm which .tar you should download for your specific device.
2. Copy the update to your device's update share.
   • via SCP to /storage/.update
   • via Samba to "update"
3. Reboot the device, and the update will begin automatically.

IMPORTANT Known Bugs/Issues

Clone Devices With Single Sticks

Right now there are issues with single stick units, we are working to fix this while we wait for our development units to arrive.

Powkiddy RGB20 Pro and Clones

Currently there are no leds working when uOS is running. Charging led works if the unit is powered off. We are working to fix this.

Powkiddy X55

This device has a few known issues.

1. Charge the unit while its turned on, not while its powered off or sleeping.
2. Plugging the power cable in with the unit off causes it to boot. This is normal right now for the unit to charge.
3. Powering down fully for more then a few minutes at a time resets the battery meter. This IS NOT drain, its a bad meter reading.
4. And last, sleeping the unit breaks sound.

What I have been doing currently is charging the unit to 100%, sleeping the unit when not in use, then I'll wake it and reboot when I want to use it. It still has very good battery life when sleeping, as I only lose between 5% and 10% battery daily. Not ideal I know, I'm working towards a fix.

Odroid Go Advance

There is currently hotkey issues with this unit, specifically with PortMaster. Ports require a hard shutdown (not recommended).

Working for fixes on all mentioned issues and bugs. Please report bugs/issues to the uOS discord here.
