If by "post an image", you mean "paste an image", that is not supported by the forum. You can paste it, but it isn't saved.
And different models require different ways of making backups.
If I look into the script, I don't see any support for the HD51 at all, and detection seems to fail. Problem is that the maintainer hasn't been online for a long time.
I see it does support the Zgemma H7, which is hardware identical, so you could try changing
elif [ $SEARCH = "h7" ] ; then
to
elif [ $SEARCH = "h7" -o $SEARCH = "hd51" ] ; then
in backupsuite.sh and see if that fixes things.
Currently in use: VU+ Duo 4K (2xFBC S2), VU+ Solo 4K (1xFBC S2), uClan Usytm 4K Ultimate (S2+T2), Octagon SF8008 (S2+T2), Zgemma H9.2H (S2+T2)
Due to my bad health, I will not be very active at times and may be slow to respond. I will not read the forum or PM on a regular basis.
