FWIW, I started digging around in the UFI file format from Ruckus, specifically because I wanted to extract the packages
The first 84 bytes of a Ruckus Firmware image are some kind of header. From this header you can reconstruct another table, which has a number of packages with a specific size each and an offset where this table is located.
For SPR08095mufi.bin for example, this is
Code:
size_per_package: 42
num_packages: 13
pkg_table_start_offset: 512
pkg_table_size: size_per_package * num_packages = 546
Although it doesn't make sense to read size_per_package from the header, as it's hardcoded as 42 in the rest of the Ruckus code...
size_per_package is the size of each entry in the package table in bytes.
Each entry has:
2 bytes of whatever - maybe a version? (acc 2)
32 bytes for the package file name, should be zero terminated, so 31 characters + '0' byte (acc 34)
4 bytes for the offset of the package in the file after the table - this is a BIG ENDIAN coded uint32 (don't ask me why it's big endian) (acc 38)
4 bytes for the filesize of the package - - this is a BIG ENDIAN coded uint32 (don't ask me why it's big endian) (acc 42)
For SPR08095mufi.bin, this gives:

size_per_package: 42
num_packages: 13

I can share the code which directly extracts the files if you want. Allows you to extract current, most up to date bootloaders and stuff like that.
Just tested the extractor - Successfully extracts spz10118.bin from SPR08090mcufi.bin (tested by comparing MD5 hash of extracted file and known good file from archive)
