Thanks for the reply.
Yes, I deleted the pairings with other phones through Bluetooth settings. Did not mess around with anything else on the unit. I tried the testmode.key just how you mentioned but it still boots to splash screen, screen seems to flicker a little bit than the screen goes black, and 10 sec later the buttons go black. Eject button is the only button functioning.
I haven’t installed anything on it other than pairing up my iphone.
Thanks
