Alpha — guess I need an OSU file of latest build...

There are no OSU files available for Insider builds. You have to wait for the public build to catch up with the build that is on the console.

John,

Good news! I reverted to the beta build and after the update I was able to go through the setup console instructions again. It prompted a code so I am back remote with the series x 😊. I guess it was the alpha build that was messing it up. Should I try to go back to the alpha build? 🤔

Hi, there is no offline update file for preview builds. As your OS version is newer than any of those OSU files you're a bit stuck. Maybe ask on the insider reddit ?

You cannot get the OSU for the alpha. You need to unregister the console using the Xbox Insider Hub on Windows 10, then you should be able to reset the console, and download the public release of the dashboard.

There is a alpha update available today, but since you want the public update, you need to unregister the console, so it will update to the latest public build. If you cannot access the console, then download the xbox insider app on windows 10, and if you can, unregister the console.
