Upgrade Your PlayStation Portable Firmware
Games, software, or simply being up to date. Getting the new firmware for any device is great for you. And its of extreme importance for the PlayStation Portable , or simply, the PSP, as it is the world’s most widely used portable gaming console. Here’s what you need:
1] A PlayStation Portable (obviously), which should be fully charged.
2] A USB Cable/MemoryStick Duo reader to transfer the update data
3] Internet
Here are the steps:
1] Download the latest PlayStation Portable firmware from here. You may charge your PlayStation Portable while the download is on.
2] After the download is complete, connect you PlayStation Portable to your computer via the USB cable, or simply insert the MemoryStick Duo in the memory card reader.
3] Now, create a folder by the name of PSP. Open it, and create another folder GAME. Open that too and create another folder UPDATE. Take care that the folder names should be in CAPITAL LETTERS. Else, the update will not work and I will receive unnecessary curses for writing this absurd post and wasting your time, when you could be doing some takedowns.
4] Once you’ve downloaded the file, makes sure it’s called EBOOT.PBP . Transfer it to the UPDATE folder you created in the previous step.
5] Now, after you’ve made sure that your PlayStation Portable is fully charged, and yet it is plugged in to the socket with the charged ON, insert the MemoryStick Duo into your PlayStation Portable.
6] Make sure the MemoryStick Duo is detected. If not, restart your PlayStation Portable. Running the update is as simple as running a game. From the Home screen, select the Game icon, under which you select the MemoryStick Duo icon, and press X on your Update file. It should look like PSP™ Update Ver. X.XX, where X.XX stands for the latest version you downloaded.
MAKE SURE YOU DO NOT SWITCH OFF YOUR PLAYSTATION PORTABLE OR REMOVE THE MEMORYSTICK DUO WHILE THE UPDATE IS RUNNING. THIS MAY CAUSE IRREPARABLE HARM TO YOUR PSP.




Which firmware version is it? I use 3.71. I think the latest is 5.02. I would want to upgrade my psp not downgrade it.
Actually you need not get the latest firmware after 3.96. All the titles can be played using it. The only advantage you get is codecs and new visualizations in Music.
@Shikhar: I don’t know which version it is. I don’t have a PSP to try it out. Looking for
someonehim to gift it to me.I did hear that the new firmwares do not affect games, but they cause bug fixes, prevent frequent crashes, give lots of battery life. And, extra codecs are great for those who bought a PSP and an 8GB Memory Card.
the latest version is 5.something (m33) version
if you dont upgrade to a m33 version u would no longer be able to play pirated games
the original firmware by sony is 5.03(not a b33 version -no free games)
moreover upgrading on our own will not be safe because if any mis-hap happens
u will no more have a working psp only a dummy which will curse u for trying to show extradoniary intelligence and skills on it
ha
so i preffer do not upgrade it urself and leave it to the professionals
but still good post
