I Used the battery and MMS on a PSP slim But am sure it will work on Phat PSP




Materials:
----------
A psp (1)
A psp battery (1)
A memory stick pro duo with 512MB or more, NO LESS (1)
A mini USB or Memory Card Reader (1)
A computer with an internet connection (1)
A knife/exacto knife (1)
A needle, safety pin, tooth pick, etc (1)



Process #1: Creating the Magic Memory Stick
--------------------------------------------
(NOTE: this is for working psp's. so if your psp is bricked, you dont have to do this one. just go to the next process)
1)Turn on the psp and go into USB mode
2)When your computer detects the psp, go to "My Computer"
3)Right-click on your psp's drive and select "Format"
4)Format the memory stick
5)Next download the "universal unbricker"6)Place all the files inside of it onto your psp's drive. These files should include:
==three folders called "PSP", "kd", and "registry"
==three eboots called "150.pbp", "340.pbp", and "371.pbp"
==one bin file called "msipl.bin"

once done with that, move to "Process #3: Moving the Partitions"

Process #2: Creating the Magic Memory Stick with a bricked psp:
---------------------------------------------------------------
In order to do this, we are going to need a Memory card Reader/Writer.
1)Plug your Memory Stick in via Card Reader
2)Follow the above tutorial from step 2-7



Process #3: Moving the Partitions:
---------------------------------
(NOTE: Keep your memory stick in through USB or card reader)
1)Download the partition mover2)Extract the folder "msinst" to your hard drive (C:\)
3)Go to "My Computer" and find your PSP drive letter (Removable Disk ?)
4)Go to "Start"
5)Go to "Run"
6)Type in "cmd" and press OK
7)Type this in: "cd C:\msinst"
8)Next, type in "msinst ? msipl.bin" (remember No quotes) (also, replace ? with your removable disk letter)(also, use a capital letter to represent your drive. example: C:\msinst>msinst J msipl.bin)
9)It will show some stuff and give you 2 options. 1)Y=Yes 2)N=No........of course, press Y and then enter
10)You should receive a confirmation that the partitions were successfully moved( Its Not going to give you a conformation, its going to say Enter Boot Code or something like that and when you see that just exit CMD and thats it you have a Magic Memory Stick)



Process #4: Hardmodding the battery:
------------------------------------
1)Take your battery and open it using a knife or exacto knife
2)look on the main board for the display "ICO4" or "CO4" (depending on your battery)
3)Now, take a needle or something like that and remove pin #5
here is a diagram: (NOTE: you can find pin #5 easily when the ICO4 or CO4 display is facing you!!!!)
__ (pin 4) __ (pin 8)
__ (pin 3) __ (pin 7)
__ (pin 2) __ (pin 6)
__ (pin 1) __ (pin 5) <------REMOVE THIS ONE ONLY
After that close the battery back, you can tape it back up if you want



Testing your battery:
---------------------
Your will know if you successfully made your battery when:
You insert the battery and the green power LED comes on automatically.



Running the files:
-----------------
Once your battery and your memory stick are being used at the same time, you will now have a "Pandora's Battery"
so.........................
1)put in your magic Memory Stick
2)Put in your softmodded battery
*if you see your wifi LED and memory stick LED blink, you have it working!!!!!!! as though in most occasions your screen wont light up but if it does, thats always good too*
3)When your LED's are don flashing, press "[]" (square) to dump your nand flash (just in case you brick. be warned, the file is anywhere from 32MB-64MB depending on your psp)
4)After that is done, you will be required reboot, so press X (cross) when your LED's are done flashing or when instructed to)
5)Re-put in your battery and the pandora menu will load
6)Press X (cross) to install 3.71M33
7)After thats done, you will need to reboot again (press X (cross) when instructed to or when the LED's are done flashing)
