WAG320N . Request Support for. #44

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
The .bin image is lzma-something...  Tried to mount it with a loop sentence, 
but no luck so far. 
This router is quite expensive (100€) .. it would be nice if supported..

Well, extraction is supported anyway. I can't guarantee that it will re-build a 
valid firmware image - let us know if it works or not. :P

I suppose we must start listing more supported formats, or telling people to 
'try' first, then submit a ticket. Gotta love these new binwalk based scripts 
of Craig's, work on so many unknown formats.

Of course, there is a bit more risk since it means more untested devices might 
have their firmwares seemingly correctly extracted and built, but could be 
bricked on flash.

What about a page with a table of firmware that has been used with fmk , 
something like http://betaftp.co.uk/ , would then be easy to search , maybe on 
the wiki here ?

Yes, bricking is possible, but in *most* cases if the firmware isn't built 
properly the header/footer checksums won't match and the devices *should* 
reject the firmware. Not always the case though, so still be cautious.

A list of supported and tested firmware would probably be a good idea, but to 
be honest I wouldn't hold my breath. Testing takes a bit of time (and money to 
get the routers), and Jeremy and I are usually pretty busy with everything else 
we have going on. Maybe a wiki/submission page where users can report 
successes/failures would be a good idea.

I'll get my Gentoo Machine next week ... Debricking is perfectly feasible by 
software (kudos to Mr. Eko :) ) and Linksys WAG320N source tar does include 
image builder (whilst source code is another story) .. I will report feedback 
next week .. thank you so much ;)

yep... header is not supported..
'http://www.filehosting.org/file/details/285071/WAG320N_v1.00.12-A_GPL.tar.gz, 
wag320n source code is crap.. Ages ago I had managed to compile an image.. Now, 
kernel doesn't even compile... 
So I am trying to rebuild image using  the Linksys image builder, which need 
rootfs (I have it) and the kernel_fs (I don't know where to find It)

rootfs.img is 8M ... that's impossible, because 8M is the size of flash... I am 
trying vmlinuz extracted by old extract tool .. wish me luck..
this is standard build command :

/root/WAG320N_v1.00.12-A_GPL/image/cfe6358.bin --rootfsfile 
/root/WAG320N_v1.00.12-A_GPL/image/fsa.bin --kernelfile

OK.. So.. my initial need is fulfilled... the extracted fs (rootfs folder) can 
be used to rebuild a working image (using Linksys source code) by just being 
compressed and named as target.tgz .
Case closed :) .. Thanks a lot..
PD: I mean, router is still unsopported.. but at least fs can be extracted :D
