Great news! Interesting, is it the same model as 1210-52 but with the
extra ports as non combo? Or are SFP+ still combo ports with 45-48
ports? Currently 49-52 they are disabled in -52 variant but they might
introduce a problem if someone gets that fixed and they are missing in
your device. Ports are statically defined in the DTS file and they
might brick the device if missing.

Did you try the image1 firmware? It should work from the web interface
but you need to write it to the image1, not image2 slot. If it is that
close to F1 series, might be able to dual boot the device back to the
original firmware. If that doesn't work, we might need to change some
flags in the dlink image generator. Is the original firmware shared
between -f1 and -g1 series?

I would include a new DTS file/firmware generation, even if it only
includes/copies -52 variant. It would make the lives of newcomers much
easier.
