TSW202 upgrade to latest fw fail

I’m running 01.05.1 and when I try to upgrade to 01.06 I get errors. “An unexpected error Occurred”. I have tried with several units…

Hello,

Could you elaborate whether you’re upgrading via the “Server” option, or are you uploading the firmware manually (from File)?

If you are upgrading from the server, I’d suggest downloading the firmware manually: TSW202 Firmware Downloads - Teltonika Networks Wiki

And selecting Update from: File and then uploading the file.

Could you possibly send a screenshot of the error message that you’re receiving, if the issue persists?

Regards,
M.
