If anyone wants to talk to me about this that has any ideas or information to further my theory, please message me on AIM: scooterwebwiz30.
I am mainly doing this b/c I am lucky enough to have 3.41 FW (Not on PS3 much) and I like to hack games, so I am trying to get a bypass figured out.
The following is what it has come down to in the ps3-updatelist.txt from sony's servers
# US
Dest=84;CompatibleSystemSoftwareVersion=0.0000;
Dest=84;ImageVersion=0000b307;SystemSoftwareVersion=3.4200;CDN=https://dus01.ps3.update.playstation.net/update/ps3/image/us/2010_0907_6ba866514589155ab094099a9f358ffd/PS3PATCH.PUP;CDN_Timeout=30;The CDN used is referencing to 3.42 but I have hacked that to go to 3.41 via PS3 ProxyServer. Kinda on the iffy side to update doing that.
From my tinkering, it seems that their are 2 main things the PS3 checks. The ImageVersion setting and SystemSoftwareVersion. It will use the other in the instance one is missing or has a bad value.
My main question, is how in the world does it calculate the ImageVersion. If anyone knows what the ImageVersion is, it would defiantly help me out.
So as I said, if you think you can contribute to this information then contact me..
[UPDATE]: I am dropping my attempts. Here are is what I can tell you. Sony is not making it easy. Your PS3 checks the ps3-updatelist.txt . It uses any valid information to check for an update. Someone actually found the 3.41 information in a forum. It was in JP, but I converted it. Afterwards, any attempt to login or access the PSN store seem to result in a UPDATE request! So it appears they are using the login server too, to give out update "notices". Bad news there. That involves packet injection through SSL (encryption), so good luck on that...
Unless anyone has a way of sniffing and injecting on HTTP port 443, we are outta luck. BTW the login server appears to be: auth.np.ac.playstation.net:443 .. Have fun touching that CDN server.

Hmm well what I vote we should do is start backing up all versions of the update list. I have already backed up 3.42 incase of anything. Then just use that, since it is a real copy. If the image version depends on what accesses it, then giving out copies might not work.
So I recommend you download the update list asap and maybe even the update itself to make the PS3 happy. Think sony removes older updates from the server too, as I had a link to a older FW PUP and got a 404 Page error.
BACKUP YOUR PS3 UPDATE LISTS!!! If one of the open source jailbreaks rides on 3.42 and another patch comes out, those who copied it might have a bypass on their hands. Also I think that you would need to feed it the exact FW you have, as sony may have put in checks about the greater than or less than FW number as what was used in the past.
So in what I am thinking, is use PS3 Proxy server to feed the version you are on. When an update comes out, it wont know. You will just need to get copies of each version as they come and always stay a version behind to be homebrew...
