FMB020 (FW 03.27.12) "Not Supported" — likely needs intermediate firmware + internal updater tool, not standard Configurator

Telematics Issue
1

Hi all,

I have a brandnew FMB020, bought from an authorized retailer (Digitec, Switzerland). The device is detected correctly over USB — IMEI, firmware and COM port all show up — but the Configurator displays “Not supported”, so I can’t open the configuration view or reach any firmware-update option.

Device details:

  • Model: FMB020
  • IMEI: 35061207****0227 (full IMEI available on request via DM)
  • Firmware: 03.27.12 Rev:93

What I’ve already tried:

  • Latest Configurator (1.8.10) → “Not supported”
  • Older Configurator (1.7.72) → “Not supported”
  • “Create new configuration” only offers 03.28.x firmware lines — there’s no 03.27.x option in either Configurator version.
  • I obtained the official FMB.Ver.04.00.00.rev.550_and_configurator.zip bundle from the Teltonika wiki and tried the Configurator bundled inside it → still “Not supported,” no menu to load the .e.xim firmware file.

My diagnosis (please correct me if wrong):
This looks like the same pattern as other “Not Supported / no config menu” threads I found here (e.g. the FMB920-on-01.03.13 case), where staff explained that very old/special firmware can’t be bridged to a new base firmware line directly — it needs a step-by-step upgrade through intermediate firmware files, delivered via a specialized internal firmware updater application, rather than the public Configurator. If that’s the case here too, I’d rather get the right tool/files from you than keep trying combinations of public Configurator versions.

My questions:

  1. Is 03.27.12 a special/customer firmware, and is that why no public Configurator (old, new, or the one bundled with 04.00.00/Rev.550) can open it?
  2. Can you provide the intermediate firmware file(s) and the firmware updater application needed to step this device up to a supported version?
  3. Alternatively, can this be done via FOTA WEB — and if so, how do I get the device linked to a FOTA account? The device has a working SIM with mobile data, so an over-the-air update should be possible.

I’m holding off on further manual flashing attempts, since I’ve seen reports of Configurator 1.8.10 putting devices into an unrecoverable “boot mode” on failed updates — don’t want to risk that on a brand-new unit.

I’m happy to provide proof of purchase or my full IMEI / FOTA WEB account email privately if needed.

Thanks a lot for any help!

Dear @yaron,

Thank you for providing such detailed information and for the troubleshooting steps you have already performed.

We understand that the device is detected correctly by the PC, but the Configurator is showing the device as “Not supported” and preventing access to the configuration options. To properly verify the firmware compatibility and determine the appropriate update path, further technical investigation is required.

The required firmware files, specialized update tools, and firmware-related procedures cannot be provided through the Community.

Kindly create a ticket through the Partner Portal (VIP Helpdesk) or coordinate with your Teltonika Sales Manager to obtain access. Our technical support team will review the device details and provide the appropriate guidance regarding the available update options.

If you do not have access to the Partner Portal, please contact our team through the Teltonika GPS Contact Us page:

Thank you for your understanding and cooperation.

Kind regards,
Amalnath
