Can't decompress LGOG (E975) rom

[guilhem]

Hi @thecubed and thank you very much for this tool and your work.

I try to use this tool to extract modem.img from latest rom.
I'm using a CM rom and for the moment, I must erase all my phone to install KDZ then extract modem (via CWM) and then re-install CM...

I fail to decompress KDZ with you tool (but work with another).
But more important, it fail with DZ.

Here is a link to latest rom

Can you help me?

PS: and JFYI if you want to know why I update my modem, it's because I have to if I want 4G in my country :)

Hopefully this isn't a comment so late as to be worthless (I fear this is, since 2 years have past), but the one quick hack that may get you something is to get the scripts, then modify the line 'kdz_header = "\x28\x05\x00\x00\x34\x31\x25\x80"' to 'kdz_header = "\x18\x05\x00\x00\x32\x79\x44\x50"'. This is simply forcing the tool to recognize the file and the results may be unpredictable.

This is an interesting KDZ file. Seems like this one might have been created in a transition between two versions of LG's tools. Most earlier and later devices use different signatures. Alternatively I'm left wondering if the differing signature is significant somehow...
