A universal PSP unbricker/downgrader by the Prometheus project, also known as Team C+D.
REQUIREMENTS
- 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.
INSTALLATION PROCEDURE
- Connect the PSP to the PC with the Memory Stick inside via the USB Connection.
- Format the Memory Stick using any utility.
- Use mspformat to format the Memory Stick logically.
- Remove the Memory Stick and disable the USB connection.
- Connect the Memory Stick again via the USB connection of the PSP.
- Manually create the PSP/GAME (optionally PSP/GAME150) folders on the Memory Stick.
- Copy the "battery" and "installer" programs to the PSP/GAME (optionally PSP/GAME150) folder.
- Copy the 1.50 official updater as UPDATE.PBP to the root of the Memory Stick.
- Remove the Memory Stick and disable the USB connection.
- Run "installer" through the firmware on the PSP. This application will create the firmware files on the root of the Memory Stick, as well as msipl.bin.
- Connect the Memory Stick again via the USB connection of the PSP.
- Execute "msipl" application on the PC with the msipl.bin to write the IPL to memory stick.
- Remove the Memory Stick and disable the USB connection.
- Execute "battery" application on the PSP to modify the battery.
- Congratulation, you are now in posession of a "Magic Memory Stick" and a "JigKick Battery".
USAGE
- Insert Memory Stick into the PSP
- Remove power cord and insert the JigKick Battery into the PSP.
- A menu appears when the PSP boots. Follow the onscreen information and instructions.
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.
Instructions are in the readme. Use at your own risk
