Having a custom firmware enabled PSP is great. You open your PSP to a whole new world of opportunities, and if you’re an upstart software developer, the PSP can be a great starting platform. Sometimes however, there may be something, be it a new game demo or on and off PSN access, or a new game that is unavailable for use on custom firmware, that may prompt you to return to official firmware. Well, you’re in luck, if you own a PSP 1000 or one of the first editions of the PSP 2000, you can easily switch between custom firmware and any official firmware you please without flashing your nand.
What You Will Need:
1) PSP 1000 or one of the first editions of the PSP 2000
2) Rain’s Ultra Lite MMS Maker (Download Here)
3) Hellcat’s Recovery Flasher v1.60 (Download Here)
3) Magic Memory Stick (No bigger than 8 gigabytes)
4) Pandora Battery
Note* If you already own a pandora battery and a magic memory stick you may skip ahead to: How To Dual Boot. If not then read on.
How To Create A Magic Memory Stick
First you need to find out if your memory stick is MagicGate Supported. If it isn’t then you were most likely duped into purchasing a counterfeit memory stick and this method will not work.
How To Find Out If Your Memory Stick Is MagicGate Supported:
1) Turn your PSP on
2) Go to Video but do not click on it
3) Press the triangle button
4) Go to information and click on it.
5) At the end it should read MagicGate: Supported. If it reads Unknown or Not Supported then you have purchased a counterfeit. If it reads MagicGate: Supported then read on.
Creating The Magic Memory Stick
1) Download Rain’s Ultra Lite MMS Maker from the link above.
2) Install it on your computer and open it.
3) Now connect your PSP to your computer using the USB cable (Rain’s MMS Maker will automatically detect and load your memory stick drive).
4) Put the 500.pbp that came with Rain’s Ultra Lite MMS Maker into a folder you can easily find.
5) Select Make MMS
6) Congratulations, you have just created a magic memory stick.
Injecting the IPL
Turning your battery into a pandora will render it useless as a battery if you skip this step. So pay attention. It’s probably the easiest step anyway. This will allow your pandora to boot the PSP normally.
1) Open up Rain’s Ultra Lite MMS Maker once again.
2) Plug your PSP to your computer using the USB cable.
3) Now select Inject TM IPL Only
How To Create A Pandora Battery
1) Download Hellcat’s Recovery Flasher v1.60 from the link above.
2) Put it in your GAME folder
3) Exit out of USB Mode
4) In your PSP go to Game under the controller icon and click on Memory stick which is right below Saved Data Utility.
5) Find Hellcat’s Recovery Flasher and run it
6) Select “I agree now take me to the program”.
7) Go to the very bottom right above Exit where it says, ‘Make battery into a pandora one’ and click on it.
8) It should only take about a second and then you’re done. Your battery is now a pandora.
Great, now you’re done and ready to start dual booting Official Firmware and Custom Firmware.
Test Your New Pandora and MMS
Before you update to the latest official firmware, let’s test your newly acquired Pandora and Magic Memory Stick.
1) If your PSP is on, do a hard shut down. Hold the power switch up for about 2 seconds until the PSP shuts down completely. This is important. If you don’t shut it down completely, the pandora will not boot into service mode.
2) Once your PSP is completely shut down, hold the Left shoulder button and turn the PSP back on.
3) You should now be in service mode.
The menu should say the following:
Install 5.00 M33
Install 5.00 OFW
4) You see the Test M33 option? Click on it.
5) Now wait while it boots. Once the XMB appears go to System Settings and then to System Software. Your System Software should now read ‘5.00 M33-4’
Right now you are dual booting whatever your current custom firmware is, and 5.00 M33-4
6) Okay, now that you have confirmed that your magic memory stick and pandora battery are fully operational, exit out. The only way to exit out of Test M33 mode and return to your main firmware is to do a hard shut down. Once again, push the power button up and hold it for two seconds until the system shuts down. When you turn your PSP back on you will be back on your main firmware.
How To Dual Boot Official Firmware and Custom Firmware
1) Download whatever new Official Firmware you require and install it.
2) Run it from the Game directory and wait while it’s flashing the firmware. Make sure your battery is fully charged before doing this.
3) Now you are running official firmware :)
When you tire of official firmware, you can play all your homebrew using the TestM33 option in the Pandora service mode.
Here’s another quick run through to get back on Test M33:
1) Do a hard shut down
2) Hold L button while turning the PSP back on
3) In the menu click on Test M33
Congratulations, now you are dual booting official firmware and custom firmware.
Word to the wise: You should never try to run a firmware update while in Test M33. If you do this your PSP will brick. Of course now that you have a pandora battery you can quickly fix this, but it is still not recommended.
5.00 M33-4 too out of date for you? It may be old but it’s really no different than m33-5 or m33-6. Actually, the changelog’s list of changes in both m33-5 and m33-6 combined can be counted in one hand with the only major change being a memory stick reading speedup.
Here’s a tip: To play the newest PSP titles while in Test M33, download and install m33_620.prx and stargate.prx. M33_620 will allow you to play any game requiring firmware 6.20 and stargate will automatically decrypt most of the newest games.
Happy Dual Booting!
