Latest preview update gave my Xbox One X an E100 error.

This is seeming to be a popular problem with Fridays update. I have an Xbox One X that's having the same problem. Downloading the offline system update is no help either. It would appear the OSU1 file is outdated and won't help solve the problem. I tried
performing the OSU to a functioning Xbox One S, and that gave an E100 error. So my advice would be to wait for an announcement from Xbox before sending it in.

Have you tried doing a factory reset on the console? There should be an option to do this if you see the E100 error. Also, if you're in the preview program you should head over to this site https://www.reddit.com/r/xboxinsiders/
to see what others are saying about the latest update.

I hope this helps!

I've the latest preview update installed on my xbox one but if I try to access the preview forums I get also the group not found error page.

MattMainor what is the error appearing once the download finishes if this is what i think it is

(E100 Error)

On the update screen this is the xbox one equivalent to a ring of death i would suggest sending it in for a warranty or taking it to CEX for a cheaper repair that will however void your warranty.

this error plagued my xbox one x and it has been a brick since its due to a hard drive burn out but as the Blue Ray and the Hard drive come paired microsoft are the best option.
