I'm recieving an error, "cannot open PyInstaller archive from executable" while trying to update my device's firmware. What should I do?

It is possible that when attempting to update your device while using a weak cellular connection, you may encounter an error that prevents your device from updating correctly. This is due to the upgrade files in the zen_temp folder being corrupted because of the weak signal interfering with the download.

In this case, to restart the update, delete zen_temp folder in the update folder and try again over strong, broadband connection. It is recommended to not attempt updating in an area with a weak cellular connection, and if necessary, take the device to an indoor area with a strong wifi or wired internet connection. 

If you still are having trouble updating, please contact Zenseio Support by making a ticket via our Support Portal.
