Oh, the first
Basically, since you can read and write all the flash through it, just create a full dump when it's working and restore it when you hardbrick or... uh, get no display in recovery and want to fix it quickly (for anything else flashing with Odin is probably quicker)

From what I've read RIFFBox is one of the most popular ones https://www.youtube.com/watch?v=5TTjZgQYRfw, it's probably a little overpriced for what it is but it's aimed at the "professional" market of those independent service shops...
