Model: Apple TV 4K (3rd generation) Wi-Fi & Ethernet 128GB I am an Apple Systems Admin for a school district. A contractor working on new buildings/upgrades for us purchased Apple TVs outside of our Apple account. When attempting to add these Apple TVs to Apple School Manager and enroll them into our MDM (via Apple Configurator 2 version 2.17), i'm running into a few problems. When inputting the Pair Code: -Says “Pairing Failed (-402653161)”--this error code only takes me to Apple Forums that end up answerless -But device still shows up under Paired Devices and in Configurator On Step 3 of 4 when “Preparing Apple TV—Activating TVOS” -An unexpected error has occurred with “Apple TV”. The device is not connected. [ConfigurationUtilityKit.error – 0x25B (603)]--this error code also only points me to Apple Forums for Configurator problems regarding iPads -only option is “Stop” -Appears that Configurator is still working in the background Click Stop (as it is my only option), then Apple TV then disappears from Configurator. Devices appear to be wiping OS/reinstalling OS and then going back to factory default settings. They are not being added to our ASM account. Any ideas?
