antony, in order to get anything out of the NAND memory, you will require to either purchase a NAND reader $$$ or build your own. for that you will require the data sheet etc. Here is the link for a site where you can get an idea how to build it, here is more of a background information about it, and some more good information on here. There is a good reason why companies charge extensivle yfor data recovery :-) Hope this helps to get you in the right direction. Good Luck.
