Here's a way i have been spoofing my DEX CFW without using PSN patch or PSNinja. been using it for about 6 months now and haven't been banned.

1.) While signed out, make sure you have your internet connection disabled in your network settings, and also make sure that your auto sign-in box when you go to sign in is checked off.
Once you've done that, head into Rebug Toolbox and scroll over to Utilities. scroll down to the bottom on "Change Target ID" and switch to EID5: 84 (CEX).

2.) load up your game through webMAN or MultiMAN.

3.) Press triangle+R2 simultaneously to disable CFW syscalls and delete all history files.

4.) head back over to your network settings and enable your internet connection and then sign in.

I learned this off a friend of mine before when i kept having banned accounts every week lol. But hopefully this helps. Oh, and I've still been using the original CID.
