PS3 hacker blazie151 has made available PS3 Rebug 3.55 and 3.41 Stealth Custom Firmware versions for PlayStation 3 CFW users, which has been rumored to be the initial cause of the recent PSN outage.
To quote: I (blazie151) made a stealthed version of Rebug 3.55 and 3.41. These versions include ce24 and ce27 for Console ID spoofing.
Keep in mind at this time FckPSN and ce27 are useless since FckPSN doesn't blank your Console ID on SP-INT. For that reason I included ce24 as well, so that you can blank your console id with charles.
This also has a stealthed version of rebug selector tested working. Its stealthed as the tetris demo, so if you have that game already, use my homebrew stealthing application and stealth it as something else.
The 3.41 version has a stealthed rebug selector and the h4c payload stealthed too, both tested working.
To use it, place rebug's 3.55v1 or 3.41v2 pup in the same folder with the files provided in this post, and double click patch.bat. MD5 hashes included.
For the worrying ones, I didn't modify anything in coreos, so the brick risk is the same as rebugs cfw. It is tested as well. All this does is add in my stealth measures to the pup before flashing it. All credit still goes to rebug.
You can using the Stealthed Rebug PS3 CFW and the apps posted HERE. Brief guide from pcfreak30.com/2011/04/dns-trick-to-map-retail-game-servers/
Install Rebug CFW 3.55.1 and enable "SP-Int" mode by going to Debug Settings -> NP Environment and change that to "sp-int". Then for the primary DNS -- under [Settings] -> [Network settings] -> [Internet connection settings] - enter one of these IPs:
United Kingdom: 46.166.128.101
United States: 67.159.31.149
Run Cex Dex Rebug selector (under Package Manager) and set it to REBUG MODE
Note: You may need to set "sp-int" again
Create a new account on dev. PSN using the same PSN ID as your original/regular/retail/production one
Set the Primary DNS to the IP address of your Windows PC and use 8.8.8.8 as a secondary server
Then on your PC load up Server Mapper and enter the dev. addresses mapping them to production addresses (some below).
Call of Duty: World at War
cod5-ps3-dev.lsg.mmp3.demonware.net --> cod5-ps3-live.lsg.mmp3.demonware.net
cod5-ps3-dev.lsg.mmp3.demonware.net --> cod5-ps3.auth.mmp3.demonware.net
And it's only a few games that work etc but it's fairly complicated for very little gain and given very few (in comparison to before 3.60) CFW users will be connecting to PSN I'll be staying away from it.
Although modding a PS3 to run any software is completely legal (in my eyes) I'm sure Sony would love to jail somebody over this. With all the personal information floating around on PSN, not to mention financial info too, it'd be very easy for Sony to gain support to prosecute a case like this. Just stay off PSN.
Definitely possible, as barrybarryk said it really isn't worth the risk of using a modded PS3 or one with CFW on PSN. The only safe way is to get a second PS3 for PSN use while keeping the hacked one for homebrew and offline use really.
Thanks for the firmware. But I'm not going to play such a game online. It's too risky and doesn't worth with that games. If we find a way to sync our earned trophies, I would really appreciate it.
