one sec
http://www.megaupload.com/?d=NCHYHPDF to get the dumped 1.0
this is the dumped firmware if i am correct put the flash0 into a flashA folder in the root of your memory stick and the flash1 into a flashB folder in your root
* this is the 1.00 dump could not find the 2.0 but if you find it follow my steps that were used for the 1.0 dump
edit: one change if you find the 2.0 dump instead of using the 1.0 you need to pu the 1.5 flash1 instead of the 2.0's for flashA
