This exploit is not compatible with all types of internet networks.

Chrome Automatic Update Blocker

Bypass automatic updates on selected networks. This is used to keep Chrome OS downgraded or on the currently installed version of it.

ONC files can be used to convince the operating system that the device is connected to a metered internet network such as a hotspot using data, which keeps it from checking for system updates automatically.

    Instructions

  1. Navigate to chrome://network#state.
  2. In the "Favorite Networks" section, expand each network that you want to set as a metered network.
  3. Press Ctrl + A to select all, then press Ctrl + C to copy the entire network state page.
  4. Paste the copied text into the textbox input field below this line.

  5. Click the Generate & Export ONC File button below this line.

  6. When the ONC file has been exported and generated, navigate to chrome://network#general.
  7. Import the ONC file in the file upload under Import ONC File.
Your Chromebook should no longer update automatically while connected to your chosen internet networks while using this exploit.

Be careful to not stay on an unmetered internet network for too long without using CAUB on it.
