Connecting to PSN on CFW 3.55 Kmeaw *Updated*Posted by greg
Personally I haven’t tried this yet, but it seems promising… This comes from an anonymous fellow who is reporting success on connecting to PSN using PS3 Custom Firmware 3.55 by Kmeaw. So install that first and then follow these steps.
The following assumes you’re technically inclined and/or very resourceful, i.e. you know how to use Google. You’ll likely need to reference Google when it comes to generating/signing a certificate and creating a CA (certification authority). That said lets get started; here we’re using a combination of two tactics:
DNS server trick: Set Primary DNS to 67.202.81.137 under Network Settings
Simple SSL proxy that basically modifies the headers for outgoing packets to auth.np.ac.playstation.net’s to change “PS3 03.55″ to “PS3 03.56″ — this makes PSN believe the PS3 is using the proper firmware version
Got it? Now here is how we accomplish tactic #2:
Replacing a SSL cert in the CFW (in /dev_flash/data/cert) with your own CA SSL certificate
Creating an SSL certificate for “auth.np.ac.playstation.net” signed with your CA certificate
Run a DNS server on your machine that resolves auth.np.ac.playstation.net to your PC’s internal IP
Create a Java SSL proxy (basically PS3 <-> PC <-> PSN). The PC claims (to the PS3) that it is “auth.np.ac.playstation.net” and is successfully accepted because a CA signed the SSL certificate
Replace the headers sent PS3 -> PSN to specify “PS3 03.56″
ChrisTechTV (if it works) they’ll need you for this one man!
Good luck! Let us know how it goes.
Update: Looks like it works… Here is video proof:
And no, this isn’t a video tutorial. Wait for that.
