You get a black screen after starting KODI, and you have tried to unplug the box and restarting it but the problem is still there. To resolve this please try this. Go to the settings of your device, then go to Apps and find KODI. Click KODI and then try to Clear Cache (Note: Please do not hit Clear Data, as this will remove all KODI Data). Click OK to Clear Cache, if prompted. After clearing cache, just restart your device and start KODI. You should have a working Kodi now. If you still have any issues you can send us an email.
