Chromebook help

Someone gave me a Lenovo 100e Chromebook 2nd gen and i was gonna put Windows or Linux on it but he didnt tell me it was reset and it wont go past enrollment and it keeps getting enrolled in a school system i know nothing about so how do i unmanage it (dev mode doesn’t work)

You might need to get a programmer and a Linux machine with flashrom to get past the enrollment. For more information, please refer to this article on the Mr.Chromebox website Unbricking/Flashing with a ch341a USB Programmer | MrChromebox.tech
