I am currently trying to coax a Gen 1 Apple TV back to life. It has a graphics / logic glitch (white specks all over the screen, fails to boot 90% of the time and if it does boot it displays a very old firmware menu then as I try to move the cursor down the menus it crashes and gets stuck).I can’t get the unit to fully boot and / or remain functional long enough to update the Ethernet / Wifi connectivity for a firmware update, or even scroll down the menu to select the correct option to update firmware.
It’s clearly a logic board issue. The board is functional, but needs a firmware flash.
Does anyone know of any other way to force a firmware update on these units? I suspect it would come back to life.
