Pandora's Battery

NOTES AND RESTRICTIONS

• The firmware in the Memory Stick is not a full 1.50, but a minimal subset. Therefore, not all applications (such as flashers, or recovery apps) will load.
• Only Memory Stick Pro Duo are compatible. Memory Stick Duo (e.g. 32MB sticks) are not supported.
• The IDStorage cannot be totally restored, as there is no known way to regenerate it properly.
• It is strongly RECOMMENDED to make a flash dump of the PSP before any downgrading operation.
• There might be a BSOD at the end of the downgrade. This is normal, and happens on the standard downgraders.
• All hardware revisions known at this day are supported.
• This release contains no Sony-copyrighted material. All required Sony data is generated from the v1.50 update files.

Files / Items needed:

• Pandora's Battery
• 1.50 Update
• A spare PSP Battery. - Any make will do. Using a spare is best, as it will not be possible to boot the PSP in its normal state with the modified battery.
• A spare Memory Stick - Pro Duo of less than 4Gb. (256Mb should be enough for all applications).
• A PSP with a Custom Firmware - such as OE, M33 or WC, or a PSP with the 1.5 original kernel. (This means you need YOUR psp and ANOTHER homebrew capable psp)

Installation procedure (this is for the homebrew psp)

1. Connect the PSP to the PC with the Memory Stick inside via the USB Connection.
2. Format the Memory Stick using any utility (mspformat is included in the download)
3. Remove the Memory Stick and disable the USB connection.
4. Connect the Memory Stick again via the USB connection of the PSP.
5. Manually create a PSP folder in the root of the memory stick (no folders should be visible), then, if the psp is 1.5, create a GAME folder inside of the PSP folder. Otherwise, if the psp has custom firmware, create a GAME150 folder inside the PSP folder.
6. Copy the "battery" and "installer" programs to the PSP/GAME (optionally PSP/GAME150) folder. (These were included in the rar folder that was downloaded) Inside the GAME/GAME150 folder should have the following folders... pandora_battery, pandora_battery%, pbfirm_install & pbfirm_install%.
7. Copy the 1.50 official updater as UPDATE.PBP to the root of the Memory Stick. (So now you should see UPDATE.PBP and the PSP folder)
8. Remove the Memory Stick and disable the USB connection.
9. Run "installer" through the firmware on the PSP. (found under game section of your psp) This application will create the firmware files on the root of the Memory Stick, as well as msipl.bin

11. Execute "msipl" application on the PC with the msipl.bin to write the IPL to memory stick.
12. Remove the Memory Stick and disable the USB connection.
