Six tracks, one album, from my own SD card. Stored inside it, as if nothing had happened, were ten favourites I had never set.</p> <p>The player is a FiiO X1, bought used, and its 128 MB NAND flash chip holds both the firmware and the player's own files. <a href="https://tsvinc.dev/posts/fiio-x1-128mb-one-page-part-6/">Part 6</a> copied the whole chip over USB into one raw image; <a href="https://tsvinc.dev/posts/fiio-x1-nand-archaeology-part-7/">Part 7</a> mapped it and found thousands of file paths from the old owner's library in its user-data blocks. The X1 runs HiBy's firmware on the µC/OS-II real-time kernel, and this part finds out what keeps those paths: which database engine, which tables, and how much of it can be read back.</p>
