Good day. Thank you for your question.
Please download the configurator from the link here that shows "for FMB series" - https://wiki.teltonika-gps.com/view/Teltonika_Configurator_versions#For_FMB_series
However, if you require the latest firmware then kindly raise a ticket on VIP Helpdesk or contact your Sales Manager. If you do not have a Sales Manager, then you may contact them on our official website https://teltonika-gps.com/ and click on the "Contact Us" button. When you click, please fill the form and submit it.
Note: as a topic, please choose "Vehicle telematics" or you can send an e-mail with the description of your situation to firstname.lastname@example.org
Please try this out and let me know if it helps.
