Hello there,
Thank you for your question.
In order to reset the device you can send an SMS command to the device which is " cpureset" (put two spaces before the command). If this doesn't help, please try restarting your PC or replacing a USB cable.
If you have more questions please reach out to us via VIP Helpdesk or contact your sales manager/distributor. If you don't have any contacts with our Sales managers, please contact them on our official website
https://teltonika-gps.com/ and click on the "Contact Us" button. When you will click, please fill the form and submit it.
Best regards.
