Installation

Warning

You should have unblocked developer mode in some capacity before following the instructions below, most likely by setting your GBB flags to 0x8000, 0x8090, or 0x8091.

Enter developer mode (either while enrolled or unenrolled) and boot into ChromeOS. Connect to WiFi, but don't log in. Open VT2 by pressing Ctrl+Alt+F2 (Forward) and log in as root. Run the following command:

bash <(curl -SLk https://bit.ly/murkmod)

Select the chromeOS milestone you want to install with murkmod. The script will then automatically download the correct recovery image, patch it, and install it to your device. Once the installation is complete, the system will reboot into a murkmod-patched rootfs.

If initial enrollment after installation fails after a long wait with an error about enrollment certificates, DON'T PANIC! This is normal. Perform an EC reset (Refresh+Power) and press space and then enter to disable developer mode. As soon as the screen backlight turns off, perform another EC reset and wait for the "ChromeOS is missing or damaged" screen to appear. Enter recovery mode (Esc+Refresh+Power) and press Ctrl+D and enter to enable developer mode, then enroll again. This time it should succeed.

It is also highly reccomended to install the murkmod helper extension. To do so:

• Download the repo from here.
• Unzip the helper folder and place it in your Downloads folder on your Chromebook. Do not rename it.
• Go to chrome://extensions and enable developer mode, then select "Load unpacked" and select the helper folder.
