PSP Unbricking/Downgrading Guide for all current hardware revisions.
PSP Unbricking/Downgrading Guide for all current hardware revisions.
This guide will help you unbrick your PSP or downgrade your PSP from any version back down to 1.50
Requirements-
- A computer running Windows (XP is probably best) There is a guide that explains how to do this on linux here
- A homebrew enabled PSP in 100% working order.
- A bricked PSP or a PSP you wish to downgrade.
- A Memory stick Pro Duo that is 256Mb or Larger (Upto 2GB). Memory Stick Pros do not work
- A USB Cable.
- A little bit of knowledge with the command prompt. Not nessecary but it will help.
- Most importantly a PSP battery (Spare battery if you can)
What is going to happen?
- Firstly you will format your memory stick using your PSP, so backup up your data first.
- Then you will run a program that modifiys that format of the memory stick to help prevent errors.
- You will then modofiy the serial number stored inside a PSP battery so that it reads 0xFFFFFFFF.
- The PSP is programmed to launch the initial-program-load (IPL) from the memory stick if the battery reads 0xFFFFFFFF.
- Any other value and it will try to boot from Flash0, obviouslly failing if Flash0 is corrupt.
- This will launch a small program that can write to Flash0 restoring a PSPs firmware.
Things you should know-
- After you have finished downgrading/unbricking, you can change the serial number of the battery so it will boot the PSP normally.
- You can also format the memory stick again and use it normally.
- All software provided in the links contain no copyright material.
- Some people have been selling unbricking services on auction websites for £30, £40...
- Dont use them, they are profiting from a group of hackers work who want this software to be free for everyone.
- The Slim PSP isn't out yet, so its unknown if this unbricker/downgrader will work on a Slim PSP.
- But it does work on all hardware revisions of the current PSP. TA-082 etc...all work
This part of the guide requires a homebrew enabled PSP, such as 1.50, any of the Dark_ALex's CFW, any version of M33's CFW....
1. Download "Pandora's Battery" from here. This is the creators' website so you may want to donate a few pennies via paypal
2. Extract "Pandora's Battery" to C:\ (OR what ever drive letter your OS is installed on) so you end up with a folder in the root of your hard drive.
Your drive should look like this-
C:\pandora\readme.txt
C:\pandora\battery\pandora_battery\EBOOT.PBP
C:\pandora\battery\pandora_battery%\EBOOT.PBP
C:\pandora\installer\pbfirm_install\EBOOT.PBP
C:\pandora\installer\pbfirm_install%\EBOOT.PBP
C:\pandora\msinst\msinst.exe
C:\pandora\mspformat\mspformat.exe
4. Backup everything that you wish to keep on your memory stick to your PC. Then from within the PSP format the memory stick.
5. Know up up a command prompt. Start -> Run -> Type "CMD" and press enter.
6. Type "C:" without the quotes and press enter.
7. Type "CD Pandora\mspformat" without the quotes and press enter.
8. Now connect your PSP to your computer and still in the command prompt type "mspformat [PSPSDRIVELETTER]" and press enter

13. Manually create a "PSP" and inside of that a "GAME" folder on your memory stick. ("GAME150" if your using a CFW)
14. Copy the contents of the "battery" folder and the "installer" folder from the inside the folder you downloaded and extracted earlier.
15. Download the official 1.50 firmware update from here, extract it and rename it from EBOOT.PBP to UPDATE.PBP

X:\PSP\GAME\pandora_battery%\EBOOT.PBP
X:\PSP\GAME\pbfirm_install\EBOOT.PBP
X:\PSP\GAME\pbfirm_install%\EBOOT.PBP

28. Run the "Pandora's Battery Creator" program on the PSP again and press [X] to convert your battery into a service Mode Battery AKA Pandora Battery
29. After you have unbricked/downgraded your PSP, launch this program again and press square to write and non servce mode serial to your PSP or press L+R to restore the serial from the eeprom.bin if you made a back up earlier.
30. You have know created a "Magic Memory Stick" and a "Jigkick battery" AKA Pandoras Battery
This part of the guide requires a bricked PSP or the PSP you wish to downgrade.
1. Remove the UMD from the PSP if there is one and remove the charger from the PSP.
