Good and bad news!
I was able to meet with the vendor that sold me my PMP. They were not helpful and had no clue about anything.
I resorted to opening up PMP to see if I could find any clues on the circuit board. It read, TX2418C V0.6
I did a google search and found a number of results in chinese. Here is one page that may help:

It describes using the nandflash exe utility. The password, when prompted, is "anyka".
I haven't been able to get the nand burner software to work because, unfortunately, I can't read chinese, but I will get a translation shortly.
I think we are very close to resolving this.
