8.1 "can't update phone"

[diapers]

I've had dev preview for 8.1 since it began, I don't have any weird things installed on my phone (I'm an actual dev). It keeps telling me there is a phone update, when I press install, it restarts the phone, shows the gears for a while then restarts and shows me this...



The version I currently have..

Joe is looking into this. See if he's got anything new on his Twitter feed.

I too had this problem. I had to downgrade back to wp8.0 and then reinstall the dev preview app and update again. This process takes a few hours but this seems like the only fix at the moment.
