Yes. Just tried it. Does not work either.
Looks like there is currently no documented way to restore Apple TV 4K to the latest official release 😟.
We'll see what procedure Apple describes for those stuck in tvOS 11.2 beta 1 without the tvOS beta profile.
Fortunately, there is a way to install the beta provisioning profile on your Apple TV 4K. This could be used to install the beta frofile on a 4th gen Apple TV without the need for a USB C cable:
- download the tvOS 11 beta provisioning profile,
- put it in a Dropbox and copy the Dropbox link to it,
- on your Apple TV 4K, go to Settings/General/Privacy and highlight "Share Apple TV Analytics",
- press the Play/Pause button on the Siri remote,
- "Add Profile" appears ,🙂
- choose it,
- use your iPhone or iPad's Apple TV remote (I use the one in the control center) topaste the Dropbox link you previously copied (if you copied it on your Mac, you can only paste it on your iOS device after a short period, therefore you might have to copy it again before you can paste it)
- replace the 0 at the end of the pasted URL by a 1 (dl=1 provides a direct link to the file instead of a link to a download page)
- click on "Done",
- install the profile,
- there is no step 11.
