Recently we ordered roughly 75 C710’s for our high school. All but one of the devices came pre-enrolled and every time we tried to enroll it we got an error that it could not be completed. We tried power washing the Chromebook and still had no luck. The only option we had was to restore the device and re-install the Chrome OS. Here is how we did it!
Warning: This process will delete everything on the device! Make sure you backup all of your information!!!
To get started head over and download the Chrome OS Image Creator. This is the tool that creates a bootable SD or USB drive for you to restore from. You can find that here: https://support.google.com/chromebook/answer/1080595?hl=en
Unlike other models I could not find a physical restart button. For all other models you can find the location of the button in the above link.
After lots of Googling I found that you can hold Escape + F3 and then hit the power button. When the screen goes black let go of the power button but continue to hold the Escape & F3 buttons. This will bring up the recovery Console.
Now we will open Chrome OS Image Creator and enter the model number displayed at the bottom of the recovery page:
After you enter the model and click next. Plug in your USB drive or SD card.
After this process is done plug in your newly made usb drive into the Chromebook. The recovery process will take over and you will be all set!
As always if you have questions feel free to let me know!
