lol I don't know if you were looking for the technical explanation, if not its basically how you first program a computer chip in most modern consumer electronics, after that you can still use JTAG or switch to using a bootloader. In the case of some people they mess up the bootloader(the device is considered "bricked), and then you have to use JTAG to recover... hope this helps...
@ivanjt, I'll try not to, but I don't even have a proper cable for it lol, I'm just using female-female jumpers... I usually check connections 3-4 times before ever hooking up power though.
