First when pandora was released everyone was really happy , with their unbrickable PSP´s , then when the slim was released , many people just bought Slim and sold their PSP´s , now after 3.60 M33 was out many users realised their error of selling the PSP , and start making threads , asking for Pandora Bat creator on the Slim , after a few days Cory149 user of maxconsole wrote and app for the slim that do the job .... Many people might find this useful, here is the info :

Quote:Open Source Pandora Battery Tool 0.2 « for SE/OE/M33 homebrew enabled kernels
------------------------------------
Note: after the initial confirmation, there are _NO_ OTHERS!
DON'T SAY YOU WEREN'T WARNED: DO NOT USE ON A PSP-200x/SLIM BATTERY!

Thoroughly tested under 3.52 and 3.71 homebrew enabled PSP kernel. (should also work on 3.60 m33 slim PSP with the old style batteries ONLY)

DO NOT USE ON A SLIM BATTERY, this may result in an unusable battery.

Allows the same options as the original Pandora tool:
service mode

writes a serial 0xFFFFFFFF to the battery eeprom (inserting the battery will power on and wait for a proper MS)
auto boot mode

writes a serial 0x00000000 to the battery eeprom (inserting the battery will power on and boot the firmware)
dummy normal

writes a serial 0x12345678 to the battery eeprom (the battery will work normally)
backup eeprom

reads the battery eeprom to a file "eeprom.bin" in the root of a MS
restore eeprom

if a file "eeprom.bin" is present, it will attempt to write it to the batteries eeprom

May not work with all old style PSP-100x batteries, and should NOT be used with PSP-200x style batteries.

Installation:
-------------
Use whatever method you'd normally use to run homebrew under 3.xx or 2.xx OE/SE/M33 kernels on your PSP.

example:
-put the folder with eboot and pbp into /PSP/GAME371
-run it from the PSP MS menu.

known issues:
-------------
-when writing a battery eeprom.bin file to a battery, an error will occur at 0x14, and subsequent re-dump will show the last 2 bytes

are different than what is expected. These appear to be non-critical issues, though full eeprom re-writes should be avoided.
-when no eeprom.bin file is present on the MS, the option to write the file to a battery will be grayed out. This is done on purpose

and shouldn't be mistaken for a problem.
-only relevant options are listed and available with any given battery.
-after the intial confirmation, there are NO OTHERS!

No warranties expressed or implied. GPL is included with the source, source modifications should be published with rebuilds.
DO NOT USE ON A SLIM BATTERY, this may result in an unusable battery.

- nem for sharing the battery syscon prototypes on ps2dev (BIG thanks!)
- Everyone involved with Prometheus for creating and releasing the Pandora project (including but not limited to Noobz)
- M33 for enabling homebrew on the kernel I tested this on
- Dark_Alex for proving CFW was possible, then going 100 steps further
- Everyone behind the forums and toolchains at PS2dev.org « without them this stuff just... wouldn't be.
- anyone else I may have forgotten.......

version history:
-----------------
0.2 - updated to support 3.71 syscon NIDs, should work under every SE/OE/M33 version to date.
0.1 - initial release, confirmed working in 3.52m33 and 3.60m33(slim) with PSP-1000 type batteries

If anyone feels I have abused the privileges of their source releases, let me know and I will try to rectify it.
