How to Create Magic Stick and Unbrick Your Psp Using Pandora Battery

Step 1: Extract the .ZIP file. Download it here.
Step 2: Insert the memory stick that you want to turn into a "magic
memory stick." Back up the contents of the stick to your computer.
Step 3: Use the built-in format tool (in the PSP System Settings
menu) to reformat your memory stick.
Step 4: Connect your PSP in USB mode.
Step 5: Open a command prompt (Start -> Run -> cmd)

Step 6: In the command prompt, switch into the 'mspformat' folder
you extracted in step 1... wherever you put it.
Step 7: Type "mspformat X" where X is the drive of your PSP. Do not
include the colon. For example, my PSP is connected at O:, so I type
"mspformat O".

You should see a prompt like this:

>>> C:psppandoramspformat>mspformat.exe O
>>> You are about to format the drive O.
>>> All data will be lost. Do you want to continue? [Y]

Type 'y'.

>>> y

and you should see

>>> Drive succesfully formatted, and partition moved.

Step 8: Disconnect from USB mode, then remove and re-insert your
memory stick. Reconnect in USB mode.
Step 9: On your memory stick, make sure that you have folders
named GAME and GAME150 in a folder named PSP. If you don't have
them, make them.
Step 10: Copy the two folders from 'battery' into GAME (for 1.50) or
GAME150 (for custom firmware). The folders should be named "pandora_battery" and "pandora_battery%", so they should be
PSPGAMEpandora_battery and PSPGAMEpandora_battery% (or
PSPGAME150pandora_battery and PSPGAME150pandora_battery%).
Step 11: Disconnect from USB mode, insert the battery you wish to
use as your unbricker, and run "Pandora's Battery Creator" from the
Memory Stick section of the GAME menu.
Step 12: ***OPTIONAL - SEE NOTE *** Press Triangle to back up the
contents of your battery's flash into a file on you memory stick. The
program will automatically exit. Run "Pandora's Battery Creator" one
more time. *Note:* This step is REQUIRED if you want to make this a
normal battery again; otherwise it's optional.
Step 13: Press X to turn your battery into an unbricking battery (a
Service Mode battery). The program will automatically exit.
Step 14: Connect in USB mode.
Step 15: Copy the Firmware 1.50 update file onto the root of your
memory stick; it should be the same place as your "PSP" folder.
Rename it to "UPDATE.PBP".
Step 16: The extracted folder "installer" contains two folders. Copy
both of these into the same place you copied "pandora_battery".
Step 17: Disconnect from USB mode and run "Pandora's Battery Firm.
Installer" from the Memory Stick section of the GAME menu.
Step 18: Press X to unpack the 1.50 firmware files into their proper
place on your memory stick. The program will automatically exit. If
this step fails, go back into USB mode and rename "UPDATE.PBP" to
just "UPDATE", then try again.
Step 19: Connect in USB mode. Look in the root of your memory stick
(where you have the PSP folder and the UPDATE.PBP file). There
should be a file named "msipl.bin".
Step 20: Copy "msipl.bin" into the folder called "msinst" that was
extracted from the ZIP file.
Step 21: In the Command Prompt, switch into the "msinst" folder...
wherever you put it.
Step 22: Type "msinst X msipl.bin" where X is the drive of your PSP.
Do not include the colon. For example, my PSP is connected at O:, so I
type "msinst O msipl.bin".
You should see a prompt like this. I guarantee that your stuff will be
slightly different; it depends on how your computer is set up, what
sort of memory stick you have, and so on. As long as you get the "Are
You Sure? [Y]" prompt, you know that the msipl.bin file is OK.

>>> C:psppandoramsinst>msinst O msipl.bin
>>> PSP MS IPL Installer
>>> Load IPL code msipl.bin
>>> 241664 bytes(59 block) readed
>>>
>>> Target DRIVE is 7
>>> Check partation Sector
>>> boot status 0x80
>>> start head 0x05
>>> start sec/cyl 0x0004
>>> partation type 0x06
>>> last head 0x0F
>>> last sec/cyl 0xB7E0
>>> abs sector 0x00000810
>>> ttl sector 0x000767F0
>>> signature 0xAA55
>>> Check BPB Sector
>>> signature AA55
>>> Check free reserved sector:OK
>>> Write ABS Sector 0x10 to 0x1E7
>>> Are You Sure ?[Y]

Type 'y'.

>>> y

and you should see

>>> Write MS BOOT CODE

That means that you now have a "magic" memory stick.
You're all set!

To unbrick a bricked PSP:

update file into the root of the "magic" memory stick, namd
UPDATE.PBP, just like in step 15 above.
