so I bought a chromebook from a garage sale while I was out of town just so I could have something to brows the interwebs with. But its auto enrolled in some school and whoever set up the precautions really knew what they were doing. So far I have tried power washing, but it auto enrolls, I have tried to install a new os on it, but developer mode says its disabled. So how can I get around it either by re enableing dev mode or anouther way.
