Im going to explain this as easy as possible for you There are 2 very different types of keys at work here... and there are multiple different values of these 2 keys for different parts of the system.
First of all, the riv/erk keys are used to symmetrically encrypt executables using a AES-CTR cipher, and the key for this on the metldr is what is referred to as the "root key", because every other key can be discovered by following down this chain and decrypting each level firmware and its loader (lv0, lv1, etc).
Secondly, the public/private keypair is used only to digitally sign the hash of the executable. Each loader effectively checks the signature of the "loader" (lv1, lv2, game, etc) to ensure that it is officially authorized by Sony. The current private components of these keys were compromised during Sony's failure to understand "randomness" allowing us to digitally sign new firmware, executables, etc.
So to answer your question We already have the metldr key, the thing is that they don’t use metldr anymore, at all.Sony removed all the loaders, no more isoldr/lv1ldr/lv2ldr/appldr they added lv0.2 which seems to have secured the ps3 for now

Lol this is an awsome explanation. I couldn't have said it better myself. Im still kinda noob as far as understanding certain processes and i was actually just recently looking into understanding of all the stuff thats been released so far starting with the 3.55 keys. Do you have any references to point me towards in understanding everything else a bit more?... Im reading through Graf's documents also. As well as im about to take another attempt at a few simple solders on the circuit board. I've not a steady enough hand to attempt the nand chip right now on this ps3... it was the first thing I attempted for my first solder... didn't turn out well once I got to the points in the middle... but you gotta start somewhere. Im really good with hardware and software as far as a pc is concerned but only recently started getting into circuit level mechanics, codes, and operations. Any help or references you could point me toward would be very helpful as it appears you already have some extent of knowledge on the ps3. Thanks again PS3Prodigy.
