Warning
while i intend to make it stop phoning home to Google Admin Console (GAC), AS OF NOW IT STILL WILL PHONE HOME ON INITIAL ENROLLMENT, AND SHOW AS POWERED OFF WHEN POLICYEDIT IS APPLIED. please DO NOT use this unless you're confident you won't get caught. excercise your best judgement.
murkmod is a continuation of fakemurk and mush that includes additional useful utilities, with the most prominent being a policy manager. the original can be found here progress on integrating policyedit is very good, howver, i am waiting for vk6 to respond on how i should handle licensing though seeing as rainestorme put an MIT license while policyedit uses gpl-3
Note
You should have unblocked developer mode in some capacity before following the instructions below, most likely by setting your GBB flags to 0x80b1 (recommended), 0x8000, 0x8090, or 0x8091.
Warning
murkmod is not officially tested on any release milestone past v118 (pheonix). It will likely continue to work on future versions, but use caution with anything >v122.
with integrated policyedit, it should be possible to modify user policies by simply changing the scope from user to machine; this also negates the need for pollen entirely. this'll ideally allow you to boot modern (132+) versions while still having control over policies!!
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/al-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
helperfolder and place it in your Downloads folder on your Chromebook. Do not rename it. - Go to
chrome://extensionsand enable developer mode, then select "Load unpacked" and select thehelperfolder.
