Creative Zen Vision:M
mcuelenaere:
So I tried extracting nk.bin out of the .exe, but didn't came far..
If you split the .exe into the PE-format (there's a template for 010 Editor here), you get:
* .text
* .rdata
* .data
* .rsrcsections. The raw ZLIB compressed data is in the .data section; maybe some of the Huffman trees are in the .rdata section, I couldn't extract them cause I don't really know how they look like.
I ran the data from the .data section through WinRAR, PHP's gzinflate() function ( & others) and some universal unpacker program; but they didn't find anything useful.
Now if anyone has some experience with this, could they take a look at it?

This is somewhat unrelated to the Zen Vision M, but you may enjoy reading this. It's a patent from Creative for "controlling distribution of protected content." (see http://www.freepatentsonline.com/20070014403.html) I was looking on google for "creative hash algorithm" and various other searches (who knows, I figured it was worth a try).

Oh no :( its encrypted and hashed many times by reading that. Best way now it seems is literally to dig through the code of the firmware updater (as it says its encrypted when transferring to the device), and/or the code of the bootloader.

I don't think that patent has anything to do with the Zen Vision M.
