Chromebook Tips&Problems

• If a students can't see the school Chrome Webstore,
  Students need to login email account.
• Examview Flash error; Flash was blocked for Examview, it says an extension is blocking it.
  On G Suite Admin Console; *Flash* in "Enable Plug-In", then it works.
• Problem: When you do a soft wipe and log back on a Chromebook, the extensions are not loading up right away and sometimes you have to wait for a half an hour for them to show up. The filter extension also show up late.
  Solution: All forced extensions are being installed on the chromebooks. The installation time depends according to the speed of chromebook and internet connection. The best way, do not put all extension as "Force to Install", only put iBOSS extension. Put the useful extension in your domain chrome store, so students can install any extension, if it is needed. There is no priorty rank for installing extension right now!(2/10/2017) If the priority feature will be in the future. You can put iBOSS at the first place, then you can choose "Force to install" for all extensions. But it makes the chromebook slow... More extension, more memory and more time. So, I think it is the best way. 
• What needs to block on Google Admin Console? (Do it under URL Blocking)

  chrome://settings-frame
  chrome://flags/
  chrome://extensions/

• Recover your Chromebook: If you have “Chrome OS is missing or damaged.” error.
  First reboot your Chromebook. If you still have same error.
  Visit https://support.google.com/chromebook/answer/1080595?hl=en If it doesn’t work visit https://cros-updates-serving.appspot.com/ and download the iso file. Then use a software to create bootable USB. ( I prefer Rufus. ) Then, press esc+refresh+power button together.Then, it might give you error message again. Just shut it down and turn it on back. You will be fine.
  Then update your Chromebook. https://support.google.com/chromebook/answer/177889?hl=en
