Hello @RUFAA ,

It’s possible that the issue you’re experiencing could be related to the firmware version of your device. I recommend trying to install a different firmware version to see if that resolves the problem and rules out any potential hardware malfunctions.

Hello,

If you’ve attempted all the steps you mentioned and none of them have resolved the issue, it appears that there may be a hardware problem. If your device is still under warranty, please reach out to your Teltonika reseller or contact Teltonika directly, especially if you made the purchase directly from us. We will then initiate the RMA process.

Best regards,

Marijus
