LEGEND
WPSP - ur working psp
BPSP - ur bricked psp
MC - Memory Card
USB - USB Connection/Cable
Batt. - Battery
CMD - Command Prompt

Ok, now ur done, lets get on to it

Step 1:Formatting of MC

BACKUP UR FILES INSIDE!!Prevent yourself from starting games and etc ALL OVER again.

Connect the WPSP under the 1.50Kernal to your Computor Via USB.
Once done, Go to Start>Run>CMD
Extract the files of the Pandora's Battery to your C:\
Next,
Go to your CMD and type:

cd C:\

after that,type,

cd mspformat

next,

mspformat.exe <drive letter ur psp is connected from>

e.g,my psp is connected to J:\ , so i will type:
mspformat.exe J [you can exclude the ' :\ '

Hit Enter,[I'll replace the drive letter as ' * '] you'll get something similar;

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

hit ' Y ' [If your wondering where is that ' Y ', its found on your keyboard, between 'T' and 'U' diagonally below '6']

after hitting Y, you'll get something similar;

Drive successfully formatted, and partition moved.

After formatting, disconnect the connection, take out the MC and re-insert into ur WPSP. Connect again to your Computer Via USB Cable.

Step 2:Making of Pandora's Battery
As your MC is formatted, its clean inside.

Create your PSP folder at the root of the MC,
Inside the PSP folder, a GAME/GAME150 folder(depending on which FW ur using)

Once Finished, Place the Battery and Battery% into the GAME/GAME150 Folder.

Start the program under games, ' Pandora's Battery Creator '

**If you have only ONE Battery, make sure to press the '/\' to backup the battery serial, so you can convert it back to a normal battery afterwards**

the backup file will be 'eeprom'

If you did a backup, the program will exit itself.Hence,start the program again.

This time, press X to make your battery,the program will exit itself again.

Your battery is now a 'Pandora's Battery'

Step 3:Making of Magic MC
You are Halfway there already..bear with it!!

Go back to USB Mode(Connect to the Computer Via USB Cable)

Rename your downloaded Original FW EBOOT FILE and not the whole folder, 1.50 to ' UPDATE.PBP '[If you havent download it earlier, the link is at the top of this thread]

Place the Installer and Installer% folders into the GAME/GAME150 Folder.
Once all are at the right places, exit the USB Mode.

Go to Games, and run the 'Pandora's Battery Firm. Installer'

In the program, press X to unpack the 1.50 FW files and the program will exit itself.[If it fails, rename your UPDATE.PBP to just UPDATE]

Once exited, go to USB Mode again, and copy the newly created file you can find inside ur MC, 'msipl.bin' or 'msipl' it does not matter.

Copy that file into your C:\msinst [one the extracted files in C:\ mentioned earlier]

Go to your CMD again,

type these respectively,after each line, press the ENTER key...

cd C:\

cd msinst

msinst * msipl.bin [Note- Remember the ' * ' represents the drive letter excluding the ' :\ ']

once these are done; u should see these following sentences.

>>> C:\msinst>msinst * msipl.bin
>>> PSP MS IPL Installer
>>> Load IPL code msipl.bin
>>> 241664 bytes(59 block) readed
>>>
>>> Target DRIVE is 7 [the drive number MAY differ, it does not matter anyway]
>>> 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]

Press ' Y ' to start the making of Magic MC.

**If you do not get the Confirmation, most possibly you did not format using the mspformat, if thats the case, do that now before continuing.**

Step 4: Unbricking your PSP
Finally the Final Step =D

Insert the Magic MC(MMC) to your BPSP, and after that insert your Pandora's Battery(PB) into your BPSP as well.

If the WLAN,MC and POWER LED Lights are lit up automatically, you have successfully created the pandora's system.

A recovery menu will appear on ur BPSP, press X to continue, once the UPDATE.PBP/UPDATE file is detected in ur MMC, it will bring u to another menu which will flash the 1.50FW to ur PSP,Unbricking it by other means.

Once completed, you have successfully UNBRICKED Your PSP!! =D[For single battery/MC users continue reading]

**For Steps to upgrade to 3.52M33-4, download the files and read the readme yourself =D**

Optional Step:

For Single Battery:
MAKE SURE UR BATTERY HAS BEEN BACK-UP USING ' Pandora's Battery Creator '!!
if you deleted it or so, ' eeprom ' dun worry, continue reading..

This can help for only those whose PSP, has complete set, meaning to say an extra MC and Batt. if not get ur fren's battery.

Run the ' Pandora's Battery Creator ' program again, and backup the NON-PB!! if the program does not load, make sure ur WPSP is running on the 1.50kernel.

once that is done, start USB Mode, using ur WPSP w/ the Batt. Backup file inside the MC, and extract it.
Put in ur MMC to ur WPSP and copy the ' eeprom ' file into your root of ur MMC, next connect it back to your Unbricked PSP(UPSP).

Start your UPSP using the AC Adapter(Charger) and insert the PB into it, Make sure you have the ' Pandora's Battery Creator ' inside the MMC.

Run the program and select ' convert memory card to normal '

once completed, ur battery is back to normal.

Single MC
This one is simple, just re-format it by using the PSP Utility, meaning to say, format ur MC using the Function available at your PSP. Settings>System Settings>Format Memory Stick

Replace your previously backed up files to be back on track =D
