Just tried this with the x86 binary just because and ran into extraction
issues as expected. I could not find other architecture options from
Broadcom's download page, but I may not have been looking well enough...
❯ b43-fwcutter ./wlc_hybrid.o_shipped
Sorry, the input file is either wrong or not supported by b43-fwcutter.
This file has an unknown MD5sum 6889dbd24abf8006de5cc6eddd138518.
https://www.broadcom.com/support/download-search?pg=Wireless+Embedded+Solutions+and+RF+Components&pf=Legacy+Wireless&pn=&pa=Driver&po=&dk=BCM4331&pl=&l=true
I guess, for now, we can keep the exception for bcm4331 and see if
future firmware extractions help.
