( this will NOT work with PSP's with TA-88v3 Motherboards PSP-3000's or PSP Go's )

We are going to do the like this:

1. Making the Magic Memory Stick
2. Make the Pandora Battery ( JigKick battery )
3. Custom Firmware the PSP to 4.01 M33-2

When this guide is done, you should have a PSP that is Custom Firmwared up to 4.01 M33-2, a Magic Memory Stick and a Pandora Battery ( if you hardmodded it that is. )

So lets get started =D

If you want to know if your slim PSP has a TA 88v3 motherboard or not, view this: ... ste-nieuws ( you will also need this: and the 3.90 Official Firmware and the 4.05 Firmware, which both can be downloaded here: )

If you want an EXACT reason why it can't be custom firmwared, go here: ... =44&t=1194

1. Making the Magic Memory Stick

This will guide you through the process of how to make a Magic Memory Stick for the PSP to boot off the Custom Firmware.

What the Magic memory Stick does is having the system files we want to replace the original PSP's system files with, which in this case is the Official Firmware with our Custom Firmware.

This is also why we need to have a Pandora Battery, because the Pandora Battery allows us to boot from the Memory Stick and depending on which 2 options we pick, it will replace the files and settings with its own.

So now since you have a basic understanding of how this works, lets get started =D

You will need a Memory Stick PRO Duo with at least 512mb of memory and a max of 4gb ( you can use your main Memory Stick, but make sure you have backed up your files on it first in case something goes wrong =D ) and a Cord to connect the PSP to the computer or a Card Reader if you don't have a chord for it or your PSP is bricked.

You Will Need:
● A Computer running Windows XP / Vista ( yes it works on that horrrid system =D yay! )
● An Internet Connection ( duh )
● winRAR ( if you don't have, download the trial here: ... 07677.html and install )

Now download these three ( 3 ) files:

4.01 Official Firmware here: ( mirror: )

Rain's Simple MMS Maker v.10 here: ... l.rar.html ( mirror: )

1.50 Official Firmware here: ( mirror: ) ( ONLY FOR PHAT PSP-1000'S )

When downloaded, extract the RainMMSFull.rar file to somewhere you will find it.


Now plug your Memory Stick ( via card reader ) or PSP ( via USB ) into your computer. Now, find the RainMMS.exe on your desktop, and double click it


When opened, it should look like this:


Now, make sure the top drop-down menu is "4.01 OFW/M33-2 (DCv7)" so this is done correctly.

When that is selected, press "Load EBOOT" then the bottom screen will open.


Now select your 401.PBP from the menu, and press "Open"


Now make sure "Format Memory Stick" box is selected, and make sure "USB Version Fake Plugin" and "1.50 Kernel addon Installer ( Once you press this, you need to load your 1.50 Official Firmware by pressing "1.50 EBOOT" and finding it from the list. ( Only for PHAT PSP! ( PSP-1000 ) )" is selected. The "Pandora Trigger Button" should be on L, if not, change it to it.

Under "Other Functions" from the drop-down menu, select "Format & Inject IPL & Create Folders" and now click "Make MMS"

Make sure, that when it is creating it, to NOT click the magic memory Stick creator.

If you click it, it will look like its frozen, and when its finished, you will have a corrupt Magic Memory Stick.

When finished, you have created your Magic Memory Stick.

2. Make the Pandora Battery ( JigKick battery )

Making a Pandora Battery allows the PSP to enter "Service Mode" which will let the PSP to boot off the Magic Memory Stick.

With booting from the Magic Memory Stick, we replace the system files that are the original PSP's firmware to the Custom Firmware.

This is also for, just say if your PSP is bricked. It replaces the stuffed up firmware with a new firmware. Using this method can also allow you do "fix" your PSP's original firmware and can also downgrade your PSP's firmware if needed.

When the PSP battery is inserted, the PSP reads from the battery's EEPROM which is in Binary Code ( 00101000101110010101001 ( not the actual code, just an example of binary ) ) Making a Pandora battery or 'JigKick' battery, sets that code to all 1's ( 1111111111111111111111 ) which makes the PSP enter 'Service Mode'

For this, I give you four ( 4 ) options.

1 is that you buy a Hybrid 2-in-1 Battery off the internet which can be used as both a Normal PSP Battery or a Pandora Battery. You can buy one here: ( when you receive it, please skip to step 3, simply because the rest of this part has noting to do with you, unless you are going to make a Pandora Battery for some stupid reason! )

The 2nd is buying a Tool Battery Converter that can convert any PSP Battery ( Phat or Slim & Lite ) into a service tool battery ( Pandora Battery ) and back again. You can buy one here: ... 00530.aspx ( when you receive it plug your battery in and press the button, now it's a Pandora Battery, now go to step 3, simply because the rest of this part has noting to do with you, unless you are going to make a Pandora Battery for some stupid reason! )

The 3rd is Softmodding the battery yourself.

Now, you will need these four ( 4 ) things

● A Phat PSP that is already custom firmwared to 4.01 M33-2 or below
● A Phat PSP battery ( one is fine, because we will be turning it back after this is done =D )
● A computer running Windows XP or Vista
● An Internet Connection ( any speed )
● winRAR ( if you don't have, download the trial here: ... 07677.html and install )

Now you need to download just one thing, that is:

LE Recovery Menu Plugin, which you can download here:

Now lets start =D

Plug your / your friends Phat PSP into your computer, and if there isnt a folder on the root of the memory stick called 'seplugins' make one. ( without the ' s )

Open it, and right click inside and go to New --> Text Document

name that text document 'vsh' ( without the ' s )

Open that newly created vsh text document.

Copy and Paste 'ms0:/seplugins/recovery.prx' into it and save it ( without the ' s )

Now, double click on the LE Recovery menu archive you downloaded, and double click the 'SEPLUGINS' folder. Now copy and paste the 'recovery.prx' file in there to the 'seplugins' folder on the PSP.

Exit USB Connection.

Now fully power off the custom firmwared Phat PSP by holding up the power button.

Now press the R shoulder button while turning back on.

You are now in the Recovery Menu.

Now navigate down to plugins. press X and then navigate down to 'recovery.prx [VSH]' and press X on it to enable on it.

Exit recovery menu.

Now on your PSP XMB ( cross media bar ), hold the R shoulder button and press the Music Note button.

When that menu comes up, go to Extends, and navigate down to 'Pandora' press X on it.

Now navigate down to Pandora Battery, and press X, then wait about 10 seconds and press X again.

Keep on pressing circle until you are out of the LE recovery menu.

Now, you have a softmodded pandora battery that works in a Phat PSP and a Slim & Lite PSP.

( you do basically the same to turn the battery back to normal )

Go to step 3.

And the 4th choice is making your own which involves opening up the case and soldering off a pin / cutting a cord, which is depending on what PSP Battery type you have.

You will need a spare battery because when you make it Pandora, there is no way of using it as a normal battery.

So lets start =D
( Please have caution with this, for if done wrongly with the Phat PSP battery, it could blow off your hand. So please caution at YOUR OWN RISK )


Making the Battery.

( Slim & Lite Battery below Phat Battery )

You Will Need:
For PSP Phat Battery
● Any PSP Phat Battery
● Guitar Pick
● Soldering Iron with a very fine conical tip
● Xacto-Knife with sharp tip / Steak knife / Scissors
● A VERY steady hand
● Crazy Glue / Super Glue / Tape

First off, you will need to crack into the case, this isn't too hard, just slide the guitar pick across the sides to crack it open


Now we need to remove the 5th pin from a chip that has the model number S93C56 printed on it. Here is a magnified view below:


The newer PSP Phat batteries have a different layout, but you will still need to remove that 5th pin from that same circuit.

Now we need to remove that pin, there are a lot of ways to do this, like snapping off the pin. But this is most likely the easiest way and less damaging to the circuit board in the battery.

Use the Xacto-Knife, and try and put it under the pin. Get someone to hold the Xacto-knife while you hold the soldering iron on the pin. When the solder melts, pop the pin up with the knife. Just make sure you don't hold it no for too long because it could make the battery too hot and the battery could blow up.

When you are done, it will look something like this:


And now your done, close the case and glue it together with some super glue or crazy glue.

Or you can tape it together, but that is not recommended because it will be very tight in the Battery Holder on the PSP and will take some effort to put it in and take it out.

And now this can be used just like a Pandora battery for either PSP Phat or Slim.

( original images links at bottom of this guide )

For PSP Slim & Lite Battery
● PSP Slim & Lite battery model PSP-S110 ( 3.6v 1200mAh ) ( original PSP Slim & Lite Battery )
● Guitar Pick
● Magnifying Glass (recommended but not needed)
● Sharp Utility Knife
● Crazy Glue / Super Glue / Packing Tape

Open the battery case using a guitar pick. Slide around the sides and bottom until the seals break.

Take a bit more care around the top breaking the seal since there is where the connectors for the circuit board connect to the top of the battery which connects to the PSP power connector.

Now that its open, there you should see a small circuit board connected to the lithium-ion battery by 2 small pieces of metallic foil. Genlty, and with a bit of time, unfold the circuit board away from the battery pack and lay out flat.


Now in the top-left corner of the circuit board, if your looking at it like I am, you should see the number 19.


Now, using the utility knife, and it being very sharp will make it easier ( this will be a lot easier if you have a magnifying glass ) cut on the '19' line.

The end product ( the cord cut ) should look something like this:


Now re fold the circuit board back into place, and put the battery back together. Now for the start here, use packing tape just to make sure it works. Once all sealed, let's test it to see if it works. Put it in your PSP. Once it touches the PSP's connectors, the PSP should turn on automatically.

( images original links at bottom of guide )

If it did, it worked and you can get rid of the packing tape and stick it together with super glue and then it is fully pandorized and cannot be turned back.

If it didn't turn back on, leave the battery in there and try turning the power on yourself. If it does, you need to make the cut deeper, if it didn't turn back on, either your battery was flat before you started, or you cut too deep and stuffed up the PSP battery entirely. If you have stuffed it, I recommend, not re-trying it, but buying a Hybrid 2-in-1 battery ( buy one here:" onclick=";return false; )

And now you have a Pandora Battery.

3. Custom Firmware the PSP to 4.01 M33-2

Now since you have a Pandora Battery ( Tool Battery / JigKick Battery ), its time to load the firmware from the Magic Memory Stick using the Newly Created Battery you just created / brought =D

You Will Need:
● PSP 1000 Phat or PSP 2000 Slim & Lite with any Official Firmware or bricked
● Your newly created Pandora Battery
● Your newly created Magic Memory Stick

Put your magic Memory Stick in the PSP but make sure the battery isn't in it.

Now hold the L Trigger Button on the PSP and insert the Pandora Battery. Your PSP's power should come on automatically and after a few seconds, it will enter 'Service Mode'

You should see something like this:


Now you should have seven ( 7 ) options ( like above ). They Are:
1. Install 4.01 M33
2. Install 4.01 OFW
3. NAND Operations
4. Hardware Info
5. Test M33
6. Shutdown
7. Reboot Device

We are going to do the first option, but first, ill explain what each option means.

The first option lets us install 4.01 M33-2 Custom Firmware on our PSP's system.

The second option updates the PSP to the Official Firmware, and in this case is 4.01

The third option copies all the files that is on the PSP system's memory to your memory card ( Approx 32mb for Phat PSP, and approx 64mb for Slim & Lite PSP )

The fourth option tells you your PSP Model, Motherboard, Tachyon, Baryon, Pommel, Nand Size and Fuse ID.

The fifth option lets you test the M33 firmware on the Magic Memory Stick ( 4.01 M33-2 )

The sixth option shutdowns the PSP

And the seventh option reboots the PSP.

So navigate up to the first option and pres X to install the Custom Firmware and when it prompts you to turn off your PSP using X, press it. Not doing so, could potentially damage your PSP beyond repair.

Now turn the PSP back on not holding any buttons. If done correctly, it should turn back on like your PSP did before any of this.

If not, redo the steps above until it did.

Now just to make sure you did the steps correctly, go into Settings --> System Settings --> System Information. The system software should read '4.01 M33-2' if not, redo the steps above =D.

If it does, you have done =D and you either un-bricked your PSP or downgraded to the newest Custom Firmware at the time of writing this =D

So put in your spare battery ( non pandorized ) and if this is your only memory stick, format the memory stick!! And now you are fully done with the Newest Custom Firmware at the time of writing this!!

While we are still here, let's take a look at the 'M33 Recovery Menu'
To get into the menu, hold your power switch up until the PSP is fully off.

And when turning back on, hold the R trigger Button

You are now in the 'M33 Recovery Menu'

Toggle USB is the same as USB Connection in the PSP's amin menu, but it is in the recovery menu.

Go down to 'Configurationâ' and press X
There you will see more stuff.
Skip Sony Logo. Well does what it says. It skips the SONY logo when turning on.
Hide corrupt icons. It hides any icons that are corrupt on the PSP menu.
Game Folder Homebrew. Has an kernel already in there, but you still need to install it on a Phat PSP! ( I think )
Autorun at '[lot more writing]' allows you to run the update EBOOTS when your PSP is turned on ( recommended to disable )
UMD Mode: Normal -UMD required-
M33 driver -NO UMD-
Sony NP9660 -NO UMD-
OE isofs legacy -NO UMD-
Fake Region. Allows you to choose which region to run UMD's on. ( not all UMD's are the same region, so id put it on Disabled )
Use VshMenu. The VshMenu is the menu for M33 on the main PSP's start screen. ( get into it by pressing select )
XMB USB Device. This lets you access your UMD from USb and others that you choose ( for normal use, leave as Memory Stick)
Charge Battery When USB Cable Plugged. Allows you to charge your PSP when the USB cable is plugged in, so you don't have to be in USB Connection while your charging with USB Cable in.
Use M33 Network Update. Allows you to update your Custom Firmware through the 'Network Update' in the PSP Menu under 'Settings'
Hide PIC0.PNG and PIC1.PNG in game menu. Hides the games picture icon and background.

Go to the top and press X on Back

( not sure what 'Run program at /PSP/GAME/RECOVERY/EBOOT.PBP' is! )

Navigate to 'Advanced' and press X
In here, you have your advanced options.
Advanced Configuration controls the Plain Nodules in UMD/ISO and Executing the BOOT.BIN in UMD/ISO
Toggle USB ( flash X ) ( where X is from 0-3 ). This allows you to enter the main system files.
Format Flash1 and reset settings. This formats the flash1 and resets the PSP's settings ( themes, wallpapers, name, etc. )

Go to the top and press X on Back

Now navigate down to 'CPU Speed' and press X
There is your speeds to change the XMB Speed ( PSP menu ) and the speed at which the UMD and ISO's run at.

Go to the top and press X on Back

Navigate down to Plugins.
In here are all your plugins that you have in that folder.

Go to the top and press X on back

Navigate down to Registry Hacks and press X
Here you have the main hacks that were built into the M33 Custom Firmware
Im not sure what Button Assign is
Activate WMA. Lets you play WMA Audio files on the PSP without a PSP internet Connection
Activate Flash Player. Lets you play .swf movies in the video menu.

To exit the recovery menu, go to the main menu by going to the top of the page and pressing back, and then go to Exit and press X

Your PSP will boot up and you should see the SONY logo booting the PSP.

Just quickly, when your PSP is on, press 'SELECT' on the PSP.

That is your VSH Menu. Go to EXIT on the bottom of it to exit.


Navigate to your Game menu and go to Memory Stick.

There is the Installer for 1.50 Kernel Addon for 4.01

Press X on it and go through the steps.
And do whatever it says.

And now you can play homebrew games on your PSP!!!

Sorry for the late reply...

Just try and remake the MMS. If your using Windows Vista/7, try running in compatibility mode with XP. But it shouldnt need it.

There have been reported problems when tyring to use memory sticks that are 4gb in size or over. try buing a smaller one (512mb is plenty).

If that doesnt work, try making the MMS on another computer.

If you still have problems, just ask.
