This exploit is not compatible with all types of networks.

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

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

    Instructions

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

  5. Click the Generate & Export ONC button:

  6. When the ONC file has been exported, 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 networks.
