[The Three Firmware Update?]

I finally got it to update the firmware, I tried 4 different USB flash drives. The last one that worked was a newer one that I never had anything on before. Hope that helps.

There's a wifi setup button on the back, press down for 4 seconds until you hear a beep, there's a green light that will flash, you should be able to connect to the MyPlayDevice in your phone WiFi Settings then open the app to connect it to your wifi network.
