The following is a description of how I went about reverse-engineering the on-flash format, and of the conclusions that I came to. My efforts over the course of about a month and a half of solid work – and a “long tail” of another five months or so – resulted in a full recovery of all pictures and videos that were stored on the SD card.

  1. Why didn’t you just unsolder the chip
    and swap it with one on a new SD card?
    Maybe that would have saved you 2 months of work!
