ADMVP

Activating Developer Mode Via Powerwash

What is ADMVP?

ADMVP is an exploit capable of completely activating developer mode on enterprise-managed Chromebooks. It was found by the Titanium Network and me (kokichi) and was released on November, Monday the 18th, 2024. If you don't know what is developer mode then go to this information page

What you will need


IMPORTANT: ALL YOUR DATA WILL BE DELETED WHEN POWERWASHING VIA DEVELOPER MODE

Executing on Chromebook

enter recovery mode on your Chromebook. This is done by pressing the power button (⏻), reload key (↻), and ESC key at the same time. Your screen should look one of the images below:

Recovery mode (groot UI) Recovery mode (old UI)

Press CTRL + D on this screen, then press enter.

It will now say something about "returning to secure mode" or that "OS verification is off". You will not actually be in developer mode, but the exploit will work regardless. Your screen should look like one of the images below:

TONORM (groot UI) TONORM+FWMP (old UI)

or if it isn't blocked by system policy skip down a little On this screen, press enter again. This will disable developer mode and powerwash the device

Once it powerwashes just try that again until you get a screen without any sort of system policy block

press CTRL + D once you get on a "os verification is off" screen without system policy
