There are two firmware resources and they can be extracted by Resource
Hacker 3.2.3 (

One is 179284 bytes long, the other is 16652 bytes long.  This is
consistent with the sizes of the secondary and primary firmware
respectively.  For instance, sf010506.hex (secondary firmware 1.5.6) is
167545 bytes long and pk010101.hex (primary firmware 1.1.1) is 16299 bytes

However, both data files seem to be encrypted.  There are no strings
inside.  gzip and bzip2 make those files longer.

I put those files here if anybody wants to decrypt them:
