That time came for a few of us at JSOF these past few months.
There comes a time when every person will need to reverse engineer an HP firmware update. Part 4 – memory map leads us to our destination.Part 3 – From NAND to RAM through sliding windows.The next parts of the series will be uploaded week by week as we write them.
This post is the first of a four-part blog series documenting the different structures and stages of the firmware update.
