Firstly when you sign into PSN on True Blue using the Certificate & FuckPSN combo you can't go online on MW2 as it will say you need to update your game to 1.13. Then when you update your game to 1.13 you get the error 80010017. Then if try and remove your IP address as the Primary/Secondary DNS and use the patchblocker and it will ask you to update. So what do you do?
Well here's my tutorial, I will explain every step so noobs have no problem getting this to work, it will be a long tutorial.
1. Install Dev_Blind and mount your flash.
2. Start up a FTP app on your PS3 and a FTP Client on your PC (Use Multiman)
3. Connect to your PS3 via the FTP client.
4. Find the Dev_Blind folder in the root, open it and find the Cer Folder
5. Rename your CA27.cer on your HDD to CA27.Bak
6. Drag and drop the download CA27.cer into the folder.
7. Go to your network settings and click custom.
8. Change your Primary/Secondary DNS to your PC/Laptop IP. (Use type ipconfig in command prompt to find it).
9. Turn of your PS3 via the power button and turn it back on.
10. Don't sign in or if signing in cancel.
11. Run FuckPSN and sign in.
12. Find the 1.11 PKG update and install it via install packages.
13. Run FTP app on PS3 and FTP client on PC
14. Find the folder for the MW2 Patch and drag and drop the Eboot.bin and Patch_mp.ff to your desktop.
15. Exit the FTP app and run MW2.
16. Install the 1.13 patch and then exit the game.
17. Load up the FTP app and FTP client.
18. Find MW2 folder and replace the eboot.bin and patch_mp.ff with your desktop version. (patch_mp.ff can be a custom patch).
19. Delete default.self and default_mp.self.
20. Now run MW2 and host bitch.
This tricks the game, making it think its on 1.13 when in fact your bypassed.
This is only for True Blue Users who can't get their MW2 running on bypass.
surely its easier to change the param.sfo version to 1.13 in the 1.11 param.sfo and then delete the default_mp.self?
