A bad update of Chrome OS, version 91.0.4472.165, has prevented some users from logging in to their accounts, or allegedly using start-loop computers (via Android Central). If you’ve found yourself locked out of your Chromebook, help is on the way: Google posted on its system status page that they’re working on a solution, which it expects to release on Wednesday. It has also pulled the update, which should prevent more users from experiencing the issue.
According to Google, the only options to immediately regain access to your Chrome OS device (if it unfortunately downloaded and installed the update) will cause the local data on the device to be deleted. If you can wait for the new solution, the issue is released, but your device should also download the update automatically. Or you can trigger the update manually using the guest account. If your computer has downloaded the bad update but has not installed it, you may want to avoid shutting it down or restarting it until the repair is out.
If you can not wait for the permanent update, Google recommends either “Powerwashing” your factory-made Chrome OS device, rolling back the update with a USB recovery key, or removing your account and adding it again. Again, all of these solutions will erase local data on your device, so be careful. Google’s status page also does not address boot looping issues – Android Central says that if you experience these issues, you will need to use the USB recovery key method to reinstall Chrome OS.
The corrupted 91.0.4472.165 update is actually the second bad Chrome OS update we’ve seen this month: Google had to pull out an update around July 7th after users discovered that some Chromebooks had their performance seriously.
