Google tests new Chrome OS revert feature for rolling back to the previous version

Google is testing a new revert feature in Chrome OS. In case the latest version isn’t working well on your device, the option lets you return to the previous Chrome OS release.

The addition was first spotted by developer and Google open-source Chromium evangelist François Beaufort in the Chromium Code Reviews for the latest Chrome OS test build. To access the feature, open the Chrome OS Settings, scroll to the bottom, click on the “Powerwash” button, and then on the reset screen simultaneously press Ctrl + Shift + Alt + R.

A new “Powerwash and Revert” button will appear. Here’s how it looks:

After you click on “Powerwash and Revert,” your device will be returned to the previously installed version of Chrome OS. Beaufort notes that all user accounts and local data will be removed, as this still wipes your device first.

The only difference is that the previous Chrome OS version is loaded instead of the current one. Without this addition, you either had to wait for the next update or go through the recovery process.

This can be a very useful feature, especially given the pace at which Google updates its Web-based operating system. The update system that both Chrome and Chrome OS use works very well to get users on the latest version. This is a great way to give back a little control to the consumer while still ensuring that most aren’t left behind because they can’t be bothered (or don’t know how) to update regularly.

It’s not clear whether Google wants to offer this feature only in its beta and development channels or if it hopes to bring the tool to the stable channel as well. In case you’re not familiar with the different “channels” Google uses for Chrome OS (as well as Chrome), it’s basically the company’s system for letting users test the latest features and fixes that aren’t quite ready.

All Chromebooks ship with the stable channel enabled, but if you don’t mind dealing with bugs, you can try the latest and greatest by switching to the less-stable beta channel or the least-stable development channel. The revert feature has been added to the development channel, and it will likely soon arrive in the beta channel.

If and when Google deems it worthy, it may also show up for all Chrome OS users as well.
