Rock the mac address back and forth. I've read in two different posts about it stalling on the loading screen and that should resolve it (suppose it's the same thing as a channel not loaded error in pvr stalker)
You must re-link the mac address in your donation to go from kodi to emulator and check serial number
how did you get the emulator on the fire stick please tell me i must know!!ive installed stb on my fire stick and entered my mac , but its not loading anything .. dont know if its to do because i was useing it in the pvr ... its all on the same device
