(adsbygoogle = window.adsbygoogle || []).push({}); I FINALLY figured out the problem for me and so many users having this problem if you have a hacked or jalibroken PS3 and your on a PS3 firmware lower then 4.76 firmware such as I (was on Rogero Rebug 4.46 CFW and used 4.76 ARCH spoof to get online) then that's why you get this error 10012 immediately when you try to sign on because spoofing your ps3 to 4.76 only lets bypass the psn log in system check but mgs server still reads that your not on the correct updated ps3 firmware. I Figured this out because the GTA5 ONLINE server does the same check and they give you a timed out error code when you try to sign on there server but hackers have found a way pass the GTA5 ONLINE server check by signing in and out psn at least 3 times.

To Fix this MGS5 10012 ERROR Code:

Step 1 - Delete Game Data and remove any mods from the PS3 (If you need to delete save game data because you used mods on it then Id Recommend you delete it and start over just to be safe so you wont get banned for real.) Also if you used multiman to fix your game eboot to work on a lower firmware then change it back using the original game eboot.

Step 2 - Update your PS3 to Rebug CFW 4.76 lite (which I did) or any custom firmware on 4.76.

Step 3 - Install everything back, update the game and enjoy

YOUR WELCOME!!!!

Well it looks like pretty much every cfw under 4.66 cannot connect to MGS5TPP online at all regardless if using a spoof. I have tested and tried again to connect online to MGS5TPP using the sen enabler spoof on every 4.46cfw but it stills gives me the error code 10012 when trying to connect to MGS5TPP servers and according to "undergroundhavn" in the above text he states that "it keeps loading at "Logging into server" screen when using Habib 4.75cfw Starbuck using a spoof. But if using mostly any cfw 4.66 and above using the latest spoof (Except for Habib 4.75cfw Starbuck) or installing the latest cfw will get you ONLINE FOR SURE! Hope this was helpful! :-)

I'm on Rebug 4.75 and never have any issues.
