Excuse me for the dumb question! :-[ I'm wondering if CW checks the correspondence between the checksum and the checksum stored in the NULL block and, if the check fails, doesn't go on with uploading the firmware... I think it could be a useful check but I don't know if you've included it: that's why I'm just guessing.
Maybe even the hacked updater makes that check... I don't know.

FRESC is the code which contains Rescue Mode (this is all documented on the wiki page).
CreativeWizard doesn't do any checksum verification whilst uploading; nor does the original/hacked firmware updater.

If so, I don't know why I can't upload the 1.30.02 firmware...

Well, the player itself does...
Have you tried updating the checksum to what CW reports it should be?

It was my first tought but CW doesn't let me modify the checksum value in the NULL block...
---EDIT---
I've extracted the firmware files from the updater packages v1.30.02, v1.41.01 and v1.51.01 downloadable at the address that you also know.
The extraction process went fine but the checksum check between the one calculated by CW and the one in the NULL block fails for all of them and I can't upload them by CW nor the hacked updater. All the other firmwares (which passed the checksum check) can be uploaded with no issues.
It seems to me that there is some kind of connection between the checksum issue and the upload issue...
Transience:
010 editor will open the device if i put it into removable disk mode, but it will only show the removable disk partition. The device is capable of formatting itself into FAT32. Perhaps the creative firmware could be modified to begin formatting at the root of the drive instead of the default location? just a thought...
