Unable to get the last insider preview HoloLens OS version

Occasional Contributor

Hello everyone,


Happy new year, I wish you all the best for 2021.


With the release of the last insider preview (20279.1006 ?) , who added Edge chromium for example, I was looking for getting my hand on this update but the HoloLens dosn't get any new Update.

I already subscribed my device to the insider program in the dev channel.


Does anyone know a solution about this issue?


Thank you

Quick sanity check I guess, have you seen this page over here and followed everything on it?

The FFU method listed over there is a little extreme, but is a solid option if you're in a rush and nothing else works.


So, as you said, I eventually went with the FFU installation, it works well.
It's very unfortunate to do it that way, hope the OS Update method is gonna be fix!

Thank you Nick,

Hello @Kent1LG , unfortantely there's a known issue on some users not being able to update.

Update error 0x80070490 work-around

If you encounter an update error 0x80070490 when updating on the Dev or Beta channel, try the following short-term work around. It involves moving your insider channel, picking up the update and then moving your Insider channel back.


Stage one - Release Preview

  1. Settings, Update & Security, Windows Insider Program, select Release Preview Channel.
  2. Settings, Update & Security, Windows Update, Check for updates. After the update, continue on to Stage two.

Stage two - Dev Channel

  1. Settings, Update & Security, Windows Insider Program, select Dev Channel.
  2. Settings, Update & Security, Windows Update, Check for updates.

Hello @evmill ,


Really sorry for the (very) late response.
I had the opportunity today to try again getting the last Insider version, and I didn't do anything and that was working.

Thank you for your time,

@Kent1LG Your device probably took the update that went out on 2/9 yesterday before you tried again. The update should have had a fix to no longer require you to use a work around. Glad everything is working for you and you're able to try out all the latest features!
