I am actually looking for this answer, as well. However, I more interested to know if I could just read and dump the data from a NAND flash chip. I have began to collect information on this subject, and would be very happy if anyone could share their knowledge.
Here is a small web journal I just started for this project. I plan to add important information as I gather it. Not sure if this can be done, but it will be fun learning as i go.
