So could it be that some code is located in Jboxcrl.crl ? Cause I think no-one has looked into it, as it seemed to be non-used..

toffe82 thought that file was some kind of loader, some people on google have various ideas.
I disassembled it, and its win32 dll (freeware of IDA works great). Theres a lot of utility functions in there, malloc, string.h stuff, etc. Also a dozen or so functions IDA doesn't recognize.
aaronwi:
Yes code is located in that, It looks like it might check the current Zen firmware, if anything, it contains a bunch of possible error messages, here are really the readable chunks, formatted for easiest read.
I notice hex code that shows up twice, I wonder if its a checksum or encryption key? in between each group of 4 digits was 4 0s

I know it's hardly a useful statement at this point, but if anyone needs a guinea pig I'd be more than happy to help out with that later. I've got a ZenVM 30GB.
I'm not exactly skilled, nor trained for that matter. I fooled around a bit with the MTP porting kit from microsoft. I did a firmware upgrade and an album transfer while running the WPD monitor. I attatched a text readout of what it said.
I'm still figuring out how to use the direct MTP software supplied with the kit :-\
It does recognize the following in MtpMon:
"Creative Zen Vision:M" "Zen Vision:M" "Flashdrive303B" "Flash Reader"
Again, I'm not particularly skilled, but this seemed like it had some promising pointers to it. Even if it only helps us figure out how to get past the checksum.

LOL turns out that was the simplified version. (Told ya I wasn't very skilled)
I have two more text files for you all on what exactly went into the firmware upgrade. One is just what happened when I started the upgrade program. The second is what actually happened during, and a little after the reboot. The WPDmon seems useful, then again, I have little clue what I'm doing :P
I'll post just starting in this comment, and then I'll post the full process in another. (Attatchment size limit)
