linksys WRT54G2V1.5_1.5.02.005_US_20120221.bin won't extract #91

Closed GoogleCodeExporter closed 9 years ago

When trying to extract files from the latest version of the linksys WRT54GV1.5 
router's stock firmware image the following error message is returned and no 
files are extracted: 
"

Extracting 1360144 bytes of  header image at offset 0
Extracting gzip file system at offset 1360144
Extracting 160 byte footer from offset 1699672
Unsupported file system 'gzip'! Quitting...

"
It seems to recognize that it is a gziped firmware image but can't seem to 
unpack it. Any ideas as to how to get around this?

gzip is not a file system, it's a block of compressed (gzip'd) data. Extract 
the block and see what's inside. It's unlikely its a *supported* file system 
that's inside, since squashfs, jffs2, and cramfs all have compression built in, 
so running them back through gzip would decrease the compression ratio. 
Regardless, this image isn't going to be one that the FMK will support at this 
time. Advice using Binwalk manually for further analysis and extraction.
