zAxis, of PSX-Scene, brings some exciting news today. He's been diligently working on an open source downgrade method, entitled PSGrade. Today he's shared his work with the public. However, it still requires some work before it is fully functional. Right now, his code still requires the dongle master key, one that is buried within the PS3 console. The good news, is zAxis feels this key can be retrieved via a 3.15 fw console.

To anyone who wants to help, here is what you have to do:
1- run the PSGrade I posted (just like jp)
2- reboot into linux (no power cycling!!)
3- dump HV (and post it)
if you dont know how to dump HV in linux, then google it (you will need to open your ps3 and solder it DONT DO IT IF YOU ARE NOT AN EXPERT!!!)
Good Luck

once you get the key, post it in key.h and try it.
Please remember, this is a work in progress, nothing is working yet (so dont ask for hexes), and nothing is for sure.
Good Luck
oh, and thanks to graf_chokolo for ... everything, Hansi for the dump, and mathieulh for PSGroove (PSGrade is a derivative of PSGroove) and everyone else.

accorking to graf_chokolo, to get the ps3 to decrypte the master key, then you have to call "Verify Response" and the master key will saved in plain text. it is called when plugin a jig, and that is what PSGrade is.
once we have the key, we will have a working jig :-)
And no 3.41 is no good even if you have dump the HV
here is my discussion with graf_chokolo:

UPDATE:
Thanks to d0zs and Tripleblacklac, PSGrade is know confirmed to initiate the challenge/response protocol on 3.50.
What that means? it means that once we have the right key, 3.50 will be in service mode using PSGrade
REMEBER we dont have a working key yet, so no service mode
