Hacking Can't downgrade from 6.60 to 6.20

[Sandwich]

Hello, every time I go on chronoswitch downgrader it works but then before the actual downgrade starts it pops up a msg saying "A later version of the system software is already installed. There is no need to update. (CAAFFFFFCF7). I am using a PSP-3001. What should I do? http://imgur.com/JQRpBIW

If your intent is to hack it, just run Infinity.

Do not downgrade.
It's dangerous and not worth the risk when there are better CFW installers out there.

Make sure you double check you've got everything done before flashing Infinity to your 3k PSP.
I've got it on me Go and it works perfectly.
