What is the Reset Glitch Hack (RGH)

Reset Glitch Hack (RGH) is a hardware modification which allows you to run unsigned code, mods, game backups, and homebrew. The hack relies on a vulnerability in the hardware found by GliGli that is triggered by sending a reset pulse to the processor at a specific moment, resulting in a power glitch that causes a bootloader hash check to return "valid" no matter what you have flashed in place of the stock bootloader. The timing of when and how long the pulse should be sent is dependent on the console and it may take some tweaking until it "glitches" and boots.
