Identifying Hardware Write-Protect

Prerequisites​

  • A screwdriver, small enough to take off the back of your Chromebook

Section I - Identifying Your Hardware WP Type​

First, we have to figure out what kind of hardware WP you have on your device, so we can properly disable it.

If you have a early model (from 2012-2013), your device has a jumper/switch WP.

If you have a pre-CR50 model (from 2014-2017), your device has a WP screw.

If you have a CR50 model (2017+), your device could fall into multiple categories:

  • Battery-tied (from up to mid-2021) - your WP is tied to whether or not the battery is connected - This is most likely your board if you used one of the publicly leaked shims
  • Jumper-based (from 2021 and onward) - your WP is controlled by an unpopulated jumper on the board

A quick google-search will tell you what category your device falls into, based on its release date. You can also check MrChromebox's Page for more information.
