Outdated Testing Software
If you are getting an error message that your testing software is outdated or not functioning, you may need to power wash your chromebook. Follow the steps below:
Sign out of the chromebook
Once signed out, Hold down CTRL, ALT, SHIFT, R at the same time.
It will ask you if you want to reset , then choose yes
It will ask you if you want to reset (again), then choose powerwash and continue to confirm
It will begin the process.
When it pops up to connect to a network, choose GCSD GUEST for this part (it will kick itself over to the real GCSD once it finishes)
Once you sign back in, you need to re-authenticate your chromebook
Please note that your chromebook may be slow for a couple of minutes after it power washes since it's catching itself up with new updates.
