Well, so far the only thing I can upload is modified strings; I can't add data to the firmware.

If I add some data (i.e. I replace HSplash.jbm with some other file) I have to update it's Size in the block, the total size of CIFF and the NULL block. Even if I do so, the ZVM still gives me an 'SendObject: Operation failed, response = MTP_RESPONSECODE_ACCESSDENIED'

Although this has nothing to do with the algorithm, this still is an obstruction in getting code on it.

edit:
I used this program to calculate the hash.
To calculate a hash: calculate it only of the CIFF block (so excluding the NULL block), use SHA1 and as HMAC: "CTL:N0MAD|PDE0.DPMP."

UPDATE:
You got to add some padding (I added 4 extra bytes and that did the job), then it will accept your firmware.

Awesome work there mcuelenaere and zook :D

Once zooks firmware utilities are up and running whats next?

err if creative has modified nano-x  dramatically we should be able to get their original source http://www.microwindows.org/faq.html

mitch04:
everytime I open device it says OpenDevice: Operation failed, details: The system cannot find the file specified. (Exception from HRESULT: 0x80070002)

I got Windows vista and im pritty sure I did the device manager right. but when i ran mtpinfup.exe it comes up then goes back down and looks like i can see an error in that 1sec. any help would be great
thanks

This thread is about porting Rockbox and Rockbox certainly doesn't use nano-x...

If you have UAC enabled, run the program elevated i.e. run it with administrative rights (as stated in the manual)
