Pandora Battery - Unbrick & Downgrade any PSP!

I'm curious if you were to "Upgrade" a 3.51 PSP to 3.52 and pull the battery out in-between the upgrade would you essentially be able to downgrade your bricked PSP to say 1.5? Or better yet does it load on a 3.5+ PSPs? I see real potential in this..

man i'm just so hyped. I have two homebrew capable psp's so if one bricks, BAM i'm alive!!!!!!!!!!!!!!!!!:thumbup: Thanks you C+D, Noobz!!
Edit: I think it works wether you bricked it or not V3N0M. So if you load it on a nonbricked one you can dg. I hope

1) Follow the readme to the letter, using a homebrew capeable psp. This will set up you magic memory stick, AND set up your battery.

2) Once you have those 2, you put them in ANY PSP (this means broken or not, whatever firmware you can think of) and it will work.

Now... 2 things that haven't been answered yet.

1) Has anyone installed 3.52 m33 after using this? IT was mentioned that it is a minimal 1.50 that's installed and some things may not work.

2) Exactly how was this done? Please I'm just dying to know because it absolutely blowes my mind. I'm referring to the battery. What exactly is done to the battery, and how the heck is it done with software? My brain is having a complete meltdown here!!!

I'm wondering the same thing.

How can a battery be changed through software? There must be something in the battery or on the connections.

And, I'm guessing that the IDStorage doesn't need to be corrupted for the IPL to load. Incredible. :eek:

N00bz, DA, C+D, others devs... even u r not gods, I still give u my bow.
The impossible now is possible. Now I just hope the slim can be done too.

if it can only run minimal things then y not run an official sony updater to version 2.71 then use the downgrader to have the full 1.50 version then u can install custom firmware. that should work.

damn, i bircked my psp 3 weeks ago, and i was gonna send it to a shop to get it restored, 70 bucks!! but now i can do it for free? thank you team C+D!! this is just to good to be true!!

The Battery has an on-board chip that tells the PSP how much power it has, etc. My guess is that this applet just adds some instructions to a part of the chip that was placed there by SONY to unbrick PSPs in-house.

EDIT: If this is the case, then it's quite likely 3rd-party batteries wouldn't work. Has anyone tested this yet?

another question... I have 2 PSPs (because I bricked one a couple of years ago, then replaced the motherboard myself) so anyway, I have 2 32MB memory sticks I don't really use. is a 32MB stick too small for this?

yeah i jokingly said people with 3.52 should just brick and use this but then someone said something back about not having flash access in 3.52.. irrelevant.. anywho i bet you can ;)
