(Yes, I've read the stickies, and I've perused some of the posts in the forum.)
I just picked up a brand-new PSP Slim with 3.80 pre-installed. I'd just like to confirm a couple of things about custom firmware before I try and go through the installation process:
1. A Pandora's Battery is required to install custom firmware on this particular model/firmware PSP.
2. There's no way to install older custom firmware that didn't require a Pandora's Battery and just upgrade to the modern custom firmware.
My trouble is that I don't know anyone with an original PSP running custom firmware, thus I can't access the files that apparently are necessary to install custom firmware on the PSP Slim, so I guess I need the Pandora's Battery.
Any clarification or help is appreciated.
