HOWTO: Upgrade PSP firmware 1.50 to 3.03 OE-B

Caution! – This may brick your PSP if the steps are not followed properly! Please follow all of the instructions carefully, and if it doesn’t work and you brick your PSP, I didnt twist your arm, or hold a gun to your head, so don’t come crying to me.

Step 1:

You will first have to upgrade to 3.02 OE-A then to OE-B before you upgrade to 3.03 OE-B. So the first thing you have to do is download 1 of the following files:

For 1.50 firmware download 3.02 Basic Installer for 1.50
For 2.71SE firmware download 3.02 Basic Installer for 2.71SE

You will not need both files, so download 1 of them. Once you have the installer downloaded to your computer, plug your PSP in and activate USB file transfer mode.

*NOTE* I backed up and formatted my memory card before installing the firmware updates, you may want to do this aswell. You will also have to have atleast 75% of the battery remaining or you will not be able to upgrade.

After activating USB file transfer mode, run the installer, choose the drive your PSP is setup as, and hit next. The installer will do everything for you. You may notice the installer stop at 37%, but let it copy all files, so sit back and relax. Once all the files are copied, exit USB file transfer mode, goto the game menu, access the memory card and you will see the Launcher for the 3.02 updater. Execute this.

You will have to agree to the agreement, do this by pressing X and the update will now start. Once the update is running DO NOT turn off your PSP, or remove the memory card! When the update is complete, it will advise you to restart your PSP manually, you can now do so.

When you restart your PSP you will get a message saying the configuration is corrupt and has to be rebuilt, dont worry, press O and re-configure your PSP.

Congratulations you have no updated too 3.02 OE-A!

Step 2:

You will now have to upgrade 3.02 OE-A to 3.02 OE-B, which is easy, just download oeb.rar which is the upgrade file. Again, reactivate USB file transfer mode on your PSP and extract the contents of oeb.rar to GAME\GAME150 on your PSP memory stick.

*NOTE* You may have to create the GAME150 folder in the GAME folder.

Once everything is copied, run the updater from the Game menu on your PSP.

Easy enough, you are now upgraded to 3.02 OE-B!

Step 3:

Now to actually upgrade to 3.03 OE-A.

First you will have to download 3.03OE-A.rar Once the files are downloaded, initiate USB File Transfer mode on your PSP and extract 3.03OE-A.rar to GAME150 in the GAME folder on your memory stick. Once all the files are copied, close down the USB File Transfer Mode, and goto the Game Menu, and run the 3.03 OE-A Updater.

Again, you will have to agree to the agreement by pressing X and the update will now start. Once the update is running DO NOT turn off your PSP, or remove the memory card! When the update is complete, it will advise you to restart your PSP manually, you can now do so.

This time I didnt receive an error stating that anything was corrupt, and everything booted up just fine.

You are now running firmware 3.03 OE-A!

Step 4:

Now you are good to update to 3.03 OE-B. Download OEB_UPDATE.RAR. Once the files are downloaded, once again initiate USB File Transfer mode, and uncompress the contents of MS_ROOT to the root folder of your PSP.

Once this is complete, exit USB File Transfer mode, and execute the 3.03 OE-B updater from the Game menu. As soon as this is complete you will be fully updated to the 3.03 OE-B Firmware. You can confirm this by going to the settings menu on your PSP and looking inside of the System Information menu.

Step 5: (Optional)

You may want to now format your memory stick again before copying any of your old files back. If you do this step, you must then initiate USB File Transfer mode once more, then go into the GAME folder, and create GAME271 and GAME150.

All of your old homebrew software can now be placed inside of the GAME150 folder and will still run. Ultimately GAME271 is for stuff that runs on the 2.71 firmware.

If you have any questions/concerns or comments. Feel free to comment below!

Howto: Downgrade PSP firmware 2.71 to 1.50

The easiest way to download your 2.71 firmware PSP would be to download the downgrader, plug your PSP into the computer using the USB cable, and run the executable you just downloaded. It will transfer all the proper files to your PSP in order to downgrade it to 1.50 firmware and also give audio commentary and some pictures of what to do while it is going through the whole process.

Why?

Why would you want to downgrade your PSP firmware you may ask? There are lots of reasons someone would want to upgrade their firmware. Homebrew software probably being the largest reason to upgrade. 1.5 firmware seems to be essential if you plan on doing development with the PSP, or running software developed and/or ported to the PSP platform.

Emulation is another reason. Sure alot of the stuff being emulated is technically illegal, there is legitimate uses for some of the emulators out there. Bochs for example runs linux, windows 95, and attempts to boot a couple of the bsds. Is there a use for this? absolutely not. Is it cool? Of course. Also, emulators play a large roll in development for other consoles. Most people cant afford the expensive development hardware that is needed to get their game on a console, so emulation is the best way of playing their work.

How?

Its easy really. Goto this url, and download the full version of the downgrader. I read you get the best results when you format your memory card pre-downgrade, and even better results when you use the default 32 meg card. So I did both and the downgrade started on the second attempt.

After you have your PSP setup, plug in the USB cable, and enable USB transfer in the Settings menu.

Go into my computer and find out which drive letter has been assigned to your PSP, then run the downgrader. Follow the onscreen directions. You will be asked which drive letter your PSP is, select the appropriate drive and continue on. All the files will be copied to your memory stick.

Once this is complete, goto the photo section and load up whats on the memory card. You will get 1 of 2 results, either a red screen which is good, or your PSP will lock up, which simply means you turn it off, and restart. Continue this process until you get the red screen. When you get the red screen let the PSP do its thing until it turns itself off.

Turn your PSP back on, you will be prompted with an error. Don’t worry about this error, just hit the circle button and continue on. You will have to reconfigure all of your settings, but once you are in, voila. 1.5 firmware.

Who?

Anyone running the 2.71 firmware can downlgrade their PSP, except for the people with version TA-082 PSPs. To check if you have one of these open up the UMD drive and look along the top, if you have a version TA-082 you will see writing along the top of the exposed motherboard. It may say ic10003. Do not attempt a downgrade if you have this version. All other versions will have no text and are good to downgrade.

Caution!

Proceed with caution. I may have succeeded with my downgrade, and so has many other people. However I am not responsible if you brick your PSP.
