You technically could do that but no. You just prep before signing on to psn so you don't get flagged and banned. Hide cfw syscalls, erase/write history, disable cobra/webmod...things like that

Oh, so it's just getting your CFW to emulate OFW as close as possible. How would I would all these things if you dont mind answering? Is PSNPatch used for all that, or is PSNinja still around?

I personally use sen enabler, you can use psnpatch and yes psninja is still around and still works

There is dualboot fw like Ferrox, that supposedly allows you to mimic OFW firmware nearly 100%, and can be reset to cfw upon reboot, or something like that. I would imagine it to be useless if the og cid for the PS3 is banned.
