All is not lost.
If you use your SD card as a clone of your device you should be able to download all the update files.
Make a copy of your garmindevice.xml from your device ,create a folder on the SD card called Garmin and paste it into it.
Disconnect your device from your PC and plug in the SD card.
Use Garmin Express to update the SD card clone and you should end up with a .system folder with the update.
You can then copy/replace the files in the system folder on your device from the SD card

From you file list below it looks like the UK & ROI map update happened and the FW was also updated ,most properly a corruption occurred of the gmapprom.img,gmapprom.unl or gmapprom.gma
What you are seeing/describing is the base map gmapbmap.img without any detailed map.

I tried that with an SD card just containing garmindevice.xml. Garmin Express saw it and wrote the files you listed above to it. I then copied all those files to my device (making a full backup first) overwriting those already present. I also removed some extra files in some of those folders.
Unfortunately when I power it up the same happens as before. Says no detailed maps present and can't unlock maps.
