If your original LabQuest is displaying a plain blue-green screen with “Vernier” on the far right, then try the following:

1. Connect LabQuest to a computer using the USB cable.
2. Start Logger Pro on your computer. Logger Pro should see the LabQuest, and the LabQuest screen should change to the double-arrow screen.
3. Once the double-arrow screen is showing, disconnect LabQuest from the computer. LabQuest will return to the plain screen displaying ‘Vernier’ text.
4. Hold the power button down for 3 seconds to turn the unit off, wait 5 seconds, and then turn the unit back on. It may take longer than usual for the system to fully boot.
5. Once LabQuest displays the LabQuest App (i.e., the Meter screen displaying the File and Sensors menus), reboot the LabQuest by tapping Home > Control Panel > Reboot. Tap OK to reboot the LabQuest.

After rebooting, the LabQuest should display the LabQuest App again and work properly.
If LabQuest still displays the plain screen or if you don’t have easy access to a computer or Logger Pro, continue on.

6. Do a hard reset of the unit, see How do I perform a hard reset on my original LabQuest unit?.
7. Once LabQuest displays the LabQuest App (i.e., the Meter screen displaying the File and Sensors menus), reboot the LabQuest by tapping Home > Control Panel > Reboot. Tap OK to reboot the LabQuest.

After rebooting, the LabQuest should display the LabQuest App again and work properly.
If LabQuest still displays the plain screen, continue on.

8. Update the LabQuest following the “Recovery instructions” section of My original LabQuest is stuck on the LabQuest logo screen..
