Error updating firmware

[thxtex]

I'm trying to update the firmware on my TECH3-EU. I use the firmware called hdhomerun3_tech_dvbc_firmware_20260313.bin.
But I get the following message:

ERROR: Error attempting to upgrade HDHomeRun.

Any suggestions to what to do?
Current firmware is 20230505

The latest TECH3-EU firmware is hdhomerun3_tech_dvbtc_firmware_20230505 which you are already running.

The firmware hdhomerun3_tech_dvbc_firmware_20260313.bin is for a different model - the TECH3-DC.

Thanks.

Then everything is OK.
