You don't have to do this, but I suggest you read the 16197 NAND.
As long as you have the CPU key, you can use it along with the NAND dump to build new glitch images (I expect a new version of XeBuild/J-Runner will be along soon with support for the new dashboard).
To anybody that reads into "support for the new dashboard", this does NOT necessarily mean a hack for it, just a new file set for building the latest JTAG/glitch image if you have the CPU key for any given console.
