So I made a mistake when I returned to OFW, help me get back to CFW?

A couple of hours ago, I had a PSP 2000 with OFW 6.60. A year or so ago, I decided to return my 5.00 M33 CFW to OFW. Now I realize that was maybe not such a good idea after all. Anyway, I managed to downgrade the OFW t o 5.03 which I seem to remember was where I started out the last time I installed CFW on it.
When I re-installed OFW on my PSP, the official battery that I got with with the machine wouldn't work properly anymore. It wouldn't, and still won't boot, and only shows a green light (probably pandora'd it), and it only works if I boot up the PSP with the AC adapter, and then inserts the battery. Either way, I still have that battery. And I have another one as well, but it doesn't say who made it on it. It's a 2400mAh V3,6 PSP-S360 Battery Pack, but that's about all I know about it. It works flawlessly with OFW.

So what I have:

PSP-2000 OFW 5.03
Original battery, probably turned into a Pandora battery (softmodded)
New batter, unmodified.

And Vista

Any quick and easy ways to get it back to CFW?

Ah, nevermind, I figured it out. Seems I had to manually activate my PSP again.

I'm looking to install CFW on OFW 6.60 but I'm finding resources either for upgrading on pre-existing CFW or on older versions of OFW. Any pointer in this regard dont mean to hijack but as solved...
