Problem
Description
HWID mismatch
A set of valid hardware identities (HWIDs) is provided by Google. Google logs

HWID is used for the following purposes:
• Auto-update new patches and software for the lifetime of the Chromebook
• Reset the Chromebook to factory settings
HWID mismatch can be caused by using unauthorized or missing parts. If the
write-protect function is not turned off before recovering the Chromebook with
the USB repair shim, it can also cause HWID mismatch.
