previous PL3 WIP, here is what should be the final Hermes v4b PSN Payload to spoof PS3 Firmware 3.41 to 3.50.

Cyberskunk over at psx-scene has barely slept in the last 4 days getting PL3 and hermes updated along with myself, and then out of nowhere
xeoe ported Hermes v4b to spoof 3.50 and beat us to it by a matter of hours =)
Once xoeo released his hermes mod Cyberskunk and I were able to get our hands on it and start to clean it up and port it for 3.41 use.
This is pretty much a FINAL release for hermes v4b unless something else useful comes along that needs to be ported in but hermes v4b is not our main focus because we are moving onto something that xoeo has come up with and are currently porting it to work with 3.41, this will most likely be the most stable port of PSGroove yet!
So please Thank Cyberskunk, xoeo, and ecosystem_mod as well as anyone else that has contributed to PSGroove for all of their insanely hard work they deserve it!
As you all know github crashed the other day, I have since fixed everything and made all the pushes so everything is good now. I also had a nightmare of a time getting the build_hex.sh to work with the latest hermes port so I have retested it about 100 times and its working perfectly.
Just to give a brief explanation of what this payload has:
• xoeo - PSN Support
• ecosystem_mod - 3.50 Spoof
• math - corrected offset
• 0x82 - debug console
• 0x09 - CECH20A / CECH20B (120GB/250GB Slim) - DYN-001
hope to find something usefull here .. hello 
...
1: Decrypt 3.50 PUP
2: Have access to eeprom
3: Control (non necessary) the lv1
one of them is done, the other 2 are in work.
Forget about the current payloads. To achieve this goal one needs a custom 350 Firmware. It should be farely clear how to make one.
1. Get a lv2 dump of the 350.
2. Apply the necessary patches for your hardware.
1. Store this custom FW on the harddrive.
2. Have a payload that pokes this custom firmware on bootup into the memory.
That's the way to go.
Curse you Sony.
