Apple TV 4K fails to update tvOS from 14 to 26

How to Update 4K Apple TV from tvOS 14 to tvOS 26?


I just received a gen one 4k Apple TV from eBay and it is still on tvOS 14. When I try to update the os it just fails. Does anyone know how to slowly update tvOS maybe by using a Mac?


Thank you for any help you can provide.


Sincerely,

Brett

Not possible to connect to a computer. See if you can do a restore, that will force it to install the latest OS. If that fails or anything else happens it may signal that there is an issue with the device. You would have to take it to Apple so they can run diagnostics and see if they can restore it there.
