Released August 22, 2007 was a method for turning damn near any PSP battery into a homemade unbricking device. Here's the video :)
Updated June 13, 2008 with annotations.
Got myself the new PSP 3000 today.
The almighty Pandora's Battery, the ultimate PSP hacking tool, *does not work* with this system.
It doesn't even turn the PSP on, like it does with the two older models.
Back to the drawing board...
I was messing around with some friends on Skype and we decided to have some fun with 1-800-4MYXBOX.
I apologize in advance for the wind noises and the echo... I have no clue where they came from.
Up until now, if you upgraded a slim PSP from the original 3.60 firmware, there was no way to get back down.
I didn't like that, so I decided to make my own installer.
It works like a charm :)
Yeah, you can customize it... if you have a Pandora and a properly-set-up memory stick. No, I'm not going to tell you EXACTLY how, because the software to do it is still a little dangerous.
The m33 whiz kids have done it again; this time, they've built upon the work of the Prometheus project's Pandora unbricker to develop a custom firmware for the new PSP Slim!
The hack requires a Pandora battery/memory stick, which means you'll need access to a PSP that can run homebrew. Also, it's *only* for the PSP Slim.
Sony, you just got knocked down a peg or two!
Though it's not clear yet whether this is just because of the Slim having twice as much memory, the web browser can now open Flash animations and web pages that were previously too big to open on the original PSP. Here we see an original PSP and a PSP "Slim+Lite" loading up the same Flash animation. The new Slim loads and plays it just fine, while the original PSP refuses to even display it.
This is just more of me tinkering with the flash on official firmware; nothing really special. I converted the "-Hex-" theme by -lilfibz- to 3.90 format and flashed it, and also flashed a gameboot.
(You do this with a Pandora battery and jas0nuk's flash-over-USB menu for Pandora. It works on any firmware, custom or official.)
