Steps to reproduce the problem:
1. From a full clean install built with recovery tool, force the automatic update in "about chromeOS" to the latest version
2. After installation done and restart, the chromebook is stuck in white ChromeOS first page with ChromeOS logo
3. Nothing happen and only a esc+refresh+power button with recovery card is working for reinstalling the system

What is the expected behavior?
have a up and running chromebook ;-)

What went wrong?
Hang on white first page with chromeOS logo

Did this work before? N/A
