Applying the Update to Your LabQuest 2

How much available memory is needed on my USB drive or Micro SD card?
A minimum of 173 MB available memory is required.
Can I have other files on my USB drive or Micro SD card?
As long as there is enough available space, you can have other files. We strongly recommend that you only have one update file on your USB drive.
What is an LQA file?
An LQA file is an automatic update file used for updates of LabQuest 2.
Why is the update faster when using a Micro SD card?
The internal communication speed is significantly faster for the Micro SD port on a LabQuest 2.
Do I need to close or quit any applications before starting an update?
You are not required to close any LabQuest program prior to applying the update. For the best experience, we recommend that you stop active data collection and save any unsaved data before starting the update.
Will I lose any files I have stored on my LabQuest when I update?
The update will not affect any files you have stored on your LabQuest.
How do I use the update file to reset the LabQuest defaults?

During the early part of the update, while the screen is displaying the “Checking Files…” message, press the Collect key until you see an asterisk added after the ”This may take a few minutes.” message. Once the file check is complete, you will need to confirm that you want to reset defaults.

Why do I have to put the update file in the root directory of my USB Drive or Micro SD card?
In order for the update to start automatically, the file must be in the root directory of the USB drive or Micro SD card. If the file is in a folder, the software will not find the update file, as only the root directory is scanned.
Can I manually launch an LQA update file?
The functionality to manually launch an LQA file was introduced in version 2.1 of LabQuest app. If your LabQuest is running version 2.1 or newer, you can manually launch an update. To do this:
  1. Tap System on the Home screen, then tap System Information.
  2. Tap Update LabQuest.
  3. Tap the USB drive or SD card icon and then browse to the update file.
  4. Tap Update to manually launch the update.
Why is it necessary to use the AC adapter when updating a LabQuest 2?
Losing power during a critical step in the update could leave your LabQuest in a non-working condition. While the chance of this is small, using a power adapter will eliminate this possibility.
Note: The Battery Calibration update cannot happen if the unit is not powered by AC.
Can I update my LabQuest 2 using the LabQuest Charging Station instead of an AC adapter?
Yes, however when using a Micro SD card, you must first insert the Micro SD card before you put the LabQuest into the Charging Station.
Can I remove the USB drive or Micro SD card during the update?
No. The update will fail if the USB drive or Micro SD card are removed while the update is in progress and can leave your LabQuest 2 in an unrecoverable state.
What changes in the LabQuest System Information should I look for to indicate the update was successful?

See the screenshots below:

Troubleshooting

I have applied the update to fix the battery issue but still seem to have problems, what should I do?
If, after applying the update, your battery still does not hold a charge or recharge as expected, try the following:
  1. Shut down the LabQuest. Tap System from the Home screen, then tap Shut Down.
  2. Disconnect your LabQuest from AC power and remove the battery.
  3. After waiting at least 1 minute, replace the battery and reconnect the AC adapter.
  4. With LabQuest powered on, charge for 12 hours.
  5. If you are still having trouble, contact Vernier for additional technical support.
I have applied the update, but the version number still does not show the correct version. What should I do?
It is likely that the update failed. Try applying the update again. If this does not work, try using a different USB drive or Micro SD card. If you still are having trouble, contact Vernier for additional technical support.
I have applied the update, but the update did not end in a screen calibration. What should I do?
It is likely that the update failed. Try applying the update again. If this does not work, try using a different USB drive or Micro SD card. If you still are having trouble, contact Vernier for additional technical support.
What do I do if the LQA update file does not launch automatically?

The update should automatically start within 30 seconds of inserting the USB drive or Micro SD card. If the update does not start automatically, check the following:

  • Be sure your LabQuest is on when you connect the USB drive or Micro SD card.
  • Verify the update file is located in the root directory of the USB drive or Micro SD card.
  • Ensure there is only one LQA file in the root directory of the USB drive or Micro SD card.
  • Try applying the update using a different USB drive or Micro SD card.
  • Delete the file from the USB drive or Micro SD card and download the file again.
  • Attempt to launch the update manually (you must already be running LabQuest software v2.1 or newer):
    1. Tap System on the Home screen, then tap System Information.
    2. Tap Update LabQuest.
    3. Tap the USB drive or SD card icon and then browse to the update file.
    4. Tap Update to manually launch the update.

If none of the above resolves the issue, contact Vernier for additional technical support.

Why does the update take so long to Check Files?
Checking Files takes approximately two minutes when using a USB drive. This is because there are several large files that must be checked to ensure they were copied properly. Checking Files is only 15 seconds when using a Micro SD card as the internal communication speed is significantly faster.
What do I do if I get a message that my LabQuest update failed?
In most cases, if the update has failed, attempting to update again will succeed. If not, try downloading the files from the Vernier website again and start the process over. If this does not work, try using a different USB drive or Micro SD card. If you still are having trouble, contact Vernier for additional technical support.
Why do I have an Auto Recovery File after updating my LabQuest 2?
If the update is applied when you have unsaved LabQuest app data, the data is stored in an Auto Recovery file as part of the update process. Access the Auto Recovery file to recover the unsaved data.

Error Messages

The update file is corrupt.
The file fails a check sum test. This can happen if the file is not fully downloaded to the USB drive or Micro SD card. Download the update file again and retry the update.
LabQuest memory is too full to proceed with the update.
This can happen if there is not enough internal memory (over 90% full). Delete some user data such as LabQuest App or Sound Recorder data files, then retry the update.
The Media (USB drive or micro SD card) is not configured correctly.
Verify that the media is not write protected. Download the file again and retry the update.
Unable to shutdown the LabQuest App.
In order for the update process to proceed, the LabQuest App must shut down. Manually shutdown the LabQuest app (File – Quit), then apply the update again.
The update was canceled because of a problem installing the Admin FS software or while preparing to reboot.
Failure in either of these steps can prevent your LabQuest from operating after a update. To resolve this issue, retry the update. If you continue to have problems, contact Vernier for additional technical support.
The update encountered a problem installing the DAQ software.
During the reprogramming process, the software detected an error in writing the changes, which could prevent the LabQuest unit from operating as expected. To resolve the issue, manually quit the LabQuest App (File > Quit) then retry the update. If you continue to have problems, contact Vernier for additional technical support.
The update encountered a problem installing the U-boot or Kernel software.
During the reprogramming process, the software detected an error in writing the changes, which could prevent the LabQuest unit from operating as expected. To resolve the issue, retry the update. If you continue to have problems, contact Vernier for additional technical support.
The update encountered a problem and was canceled.
An error occurred during the update that is likely the result of an issue with the update file. Download the update file again and retry the update. If you continue to have problems applying the update, contact Vernier for additional technical support.
The update encountered a problem reprogramming the Fuel Gauge
During the reprogramming process, the software detected an error in writing or verifying the changes, which could prevent the LabQuest unit from operating as expected. This error is likely caused by the state of the fuel gauge when the update is applied. Apply the update again. If the second update fails, reboot the LabQuest (Home > System > Reboot), then apply the update one last time. If you continue to have problems reprogramming the fuel gauge, contact Vernier for additional technical support.
The update detected an invalid MAC address on this unit.
This error is unique to the LabQuest 2.6.2 updater. Some LabQuest 2 units will fail to update because the update file cannot find the MAC address of the unit. To resolve the issue, run a newer version of the LabQuest 2 update (v2.6.3 or newer). If you continue to have problems running an update, contact Vernier for additional technical support.
