BEFORE you put the Chromebook into developer mode, the Read/Write screw AND Aluminum sticker must be removed from the motherboard. See pictures below.
Once the Read/Write sticker is removed placed the bottom plate on, but do not screw it down, it has a higher success rate without the screws of the bottom plate screwed in. Continue to the next page and follow the steps in order to change the Serial Number of the Device.
On this device, both the recovery button and the dev-switch have been ritualized. Our partners don't really like physical switches - they cost money, take up space on the motherboard, and require holes in the case.
To invoke Recovery mode:
Plug the DC Power in
Hold down the Esc + Refresh + Power until the display turns on then release.
At the screen that says the “Chrome OS is missing or damaged”, press Ctrl + D then Enter.
At the screen that says “Chrome OS verification is turned off”, press Ctrl + D, the device will restart and progress into developer mode.
Do not touch or do anything for 10-15 minutes until it progresses back to the “Chrome OS verification is turned off” screen, then press Ctrl + D
Wait until the device boots to the Chrome start screen, Press Ctrl + Alt + → (Ctrl-Alt-F2)
Once in the command prompt continue to the next page, if not in a command prompt retry the above steps.
