this method (originally found by Catakang#0987) will help you keep your
chromebook downgraded (or on the current version) without automatic updates
screwing you over using onc files, you can convince your chromebook that the
wifi that you're connected to is pay-to-use (like a hotspot using data), and
thus it will not check for updates
i cannot guarantee that this will work on every wifito start:
- go to chrome://network#state (on your school chromebook of course; if this
is blocked then ur kinda screwed lol) - scroll to the bottom of the page;
you should see a list of "favorite" wifis that you've connected to in the
past
repeat the following steps for each network that you commonly connect
your chromebook to: (yes, this works for managed school wifis too)
- click the + sign next to the wifi name - copy all the data that appears -
go back to this page (caub.glitch.me) - using the menu below, create
textboxes and paste data for one network in each box - press the "generate
onc" button below the textboxes
- once you have downloaded the file, go to chrome://network#general - click
on the "import onc" button - import the newly downloaded file
your chromebook will no longer automatically update (as long as you are
on a wifi that you used caub on) be careful not to stay on a wifi for too
long without using caub on it
