Chrome os beta 74 is now out but my Chromebook beta version is still on 73. How is this rolled out?

Question

I have been using the Dev channel so i could try version 74 but found the browser to be a bit buggy. However, since i found out 74 had been rolled out to beta i thought I could roll back to beta to receive 74 through the beta channel instead. Unfortunately beta for my chromebook is still stuck on 73.
I have an HP chromebook 11 G6 non-touch screen version

The problem was caused by an error in the update files. It appears to be a one-time thing.

We get many posts from users who are confused about Chrome OS updates. 
 
Please read this Help page to learn more about how updates are handled.

I heard that ChromeOS is now on version _____, but I am on version ____

Chrome OS devices update a few days, or even weeks after Windows, Android, and Linux. Check this website for announcements and make sure that a Chrome OS update has actually been released.

Each Chromebook model can be on a different version, due to bugs or testing issues. Before you do anything else, check this web page for your device
		https://cros-updates-serving.appspot.com/
		
Not sure about which model you have? Check the label on the bottom, or go to chrome://version and look for your device codename that will match the names in the first column of the web page.

I checked the page and my model is listed as version  _____, but I am still on ____

If Chrome OS has recently updated, you will have to be patient. The updates are rolled out in stages where a small number are updated, and then more. That is done to watch for unexpected problems.
		
If you are really impatient, you can go into Settings and manually check for updates, but that might expose you to those unexpected bugs, so it really pays to be patient.
		
If you are trying to change Chrome OS channel, there may be a problem if the version numbers are out of the normal sequence. Typically, Stable is the oldest version number, with beta and dev on newer versions. If the version numbers are the same, or a dev channel version is older than beta channel, you will have problems changing to the less stable channel.

I waited patiently. It's been a couple weeks. But I still haven't seen the update.

Are you on a managed device, such as one in a school or business environment? If so, the administrator can delay updates to ensure that there are no problems in your environment. Talk to your administrator.
		
Are you using a cellular internet connection, such as a tethered phone, or WiFi hotspot? If so, you should find a public WiFi network, and check there.  There are ways to bypass that restriction, but it will use  a large amount of data.

I'm still having a problem

If you are on a very old version of Chrome OS, the automatic process may not work. Do a Recovery, as noted in the Help page.

If you have installed, or attempted to install, Linux, you may need to do a Recovery and start over in Protected mode.
		
If you have a device where the BIOS has been modified, you are on your own. Go back to the site where you found instructions about changing the BIOS, and seek help there.
