How to remove management from school chromebook

First, powerwash the chromebook. Sign into the internet and when you get to the screen where it says “Getting device configuration” click the notification center in the bottom right corner and get ready to turn off the wi-fi. When the screen turns to “Enrolling device” Turn off the internet. It will say “Enrollment Failed” Then click the button “Enroll manually” This should pull up a screen saying “no internet”. Turn the internet back on and click the back button. Eventually, in the bottom left corner, buttons will start to appear. First, Apps (If your district has apps). Second, Browse as Guest. When Browse as guest appears, go back and forth clicking the back button and the Browse as Guest button. Eventually, the chromebook should crash when you click browse as guest. Finally, press esc + refresh + power and it will take you to a screen where it says “Chrome OS is missing or Damaged” Press Ctrl + Search (Ctrl +Shift on older models) and then press enter to go into developer mode. Then, the screen will say “OS Verification is off. Press space to enable” Press space to enable then press enter. Finally, the chromebook will reboot and the enrollment should go away. If it doesnt work, then try it again.

Sorry to break this to you but it’s pretty much impossible the chromebook is most likely managed by you’re school, and there’s only 2 solutions. 1:Contact you’re districts IT department and ask them to untie the enrollment. 2: or if you’re really tech savvy then you can change the device’s serial number breaking the admin's control which you probably cannot accomplish.

Try making a Ubuntu USB stick with another PC and make it bootable with something like Rufus. After that, plug it in to the Asus and shut the chrome book down. Now, press POWER and start pressing F12 right away.

It should boot to the Ubuntu boot loader.

If this is a Chromebook you bought: Install Ubuntu and erase the HDD

If this is a school issued device: Use the Try Ubuntu option.

If they somehow locked the boot Menu, I don’t know what else you can do other than replace the OS

First of all, it's not a good idea to use the school computer, but you're looking for a way to unlock it, not the answer, right? Let me tell you. This is a fairly easy method, so you can do it in no time. First, press the three dots on the top left. Then, press "More Tools" and press "Task Manager" from among them, and an extended function will appear in the middle of the screen. After pressing "End Process" below, you are now free.

May be late, but a kid at my school found a way a while back. In case all other methods fail, you can buy a new motherboard and replace it through the back. Make sure to get the right model. In case you have to return your Chromebook around the end of the school year (if you don't own it). When times come, switch out the motherboards again and pretend like nothing ever happened. It worked for him multiple times and it will most likely work for you too. May be pricey, but there will be little to no permanent damage.
