RAX10 - AX1800 #8

FWIW, I tried this on a RAX10, although it is not supported, but still a NETGEAR.

Got the following error message: decrypt config: invalid checksum

Using the command: ./orbicfg -decrypt NETGEAR_RAX10.cfg -out decrypt-RAX10.json

Using hexdump, it appears to me the magic number is not decoded in the file.

From my attached file: 0000000 0425 2020 8e4c 0000 674d 0d61 a2ec 5c55 would imply the magic number is 20200425.

Not asking you to revise the program, but providing you additional information on different models and configs if this would be any use to you.

I used information provided in Closed Issue #6 to gather this information.

Hi, can you share your firmware version?

This was another case of an off-by-one magic value, so I added an override for it. It should work now if you pull 66bca7d.

At this rate, I might as well add some code to retry with stated magic + 1 whenever checksum validation fails :)

Thanks. Tested and works fine.
