New OSU1 Update

Exactly the same situation.

There will never be a OSU1 file available to consoles enrolled in any Xbox Insider previews. The console has to be unenrolled from the preview before attempting an Offline System Update (OSU).

Normally, when the console is unenrolled the latest General Availability (GA) OS will be installed via the internet so a OSU is not required if your network connection is stable.

If you have unsuccessfully attempted to use a OSU1 file without unenrolling from Insiders, you need to factory reset the console.

The factory reset will install a base OS and if you have a stable network connection the console will download and install the latest OS available.

Reset console to factory defaults

System Update Solution .. Take note of the Insider section of this link

"Last Alpha Skip Ahead Update was early March 2023"

This is not true. There have been several ASA Insider updates since March 2023. There was one yesterday 20th April 2023. I suggest you visit the Xbox Insiders Reddit site regularly and /or check the Insider app everyday if you want to stay in the ASA Insider preview.

You would need a window 10 or 11 pc to do it from pc

Download the insiders hub from the ms store

However did you do a osu update before removing it? If you did you bricked your system

You are going to have to wait for Reddit support

Insiders told you not to use os always head to reddit before doing any troubleshooting when you signed up

There is a way to unbrick after osu attempt but better practice now with Reddit then sorry by skipping steps

Hello, first it's a pleasure to be able to help you today.
My name is Georges C. Welcome to the community.

Hello Roger, the OSU that is available on the site is the base system, as you are part of the Insider the ideal would be to get in touch with him through their site on Reddit.

Hi Georges,

Thanks for the speedy reply!

You mentioned that "...the ideal would be to get in touch with him through their iste on Reddit"

Who is that person on Reddit that I need to get in touch with?

OR did you mean just generate a Post on Reddit on their XboxInsider site?

Thanks,

Roger
