Look in your garmindevice.xml and tell us what the HWID is
<PartNumber>006-BXXXX-00</PartNumber>
<SoftwareVersion>0</SoftwareVersion>
<Description>ForeRunner</Description>
Then I can download the Firmware to test.

Try changing the CP value

Hi, it’s 006-B4024-00
For reference my friend has a fenix 7 and also has no luck with v3 but v2 works. Only difference is he gets a screen loading then “enable to access file” is displayed
With regards Cp do I select all and change to 1252?
Out of interest what is it you are doing? Spoofing the ID on a different device to gain access to firmware?

No, using a clone device(on SD card) with HWID 4024 and firmware version to zero normally get the latest Firmware, unfortunately not this time which suggests its not Patchable.

Thanks GarminNuvi

I missed the “select all” part, but nevertheless I actually did select all and change to 1252 and abracadabra they worked! Thanks for all of your support guys . As others have mentioned the quality compared to V2 isn’t as good . But can’t complain
