How do i remove write-protection from MemoryStickPRODuo from psp?

I would contact sony about that unless someone else here can answer that. I personally have never herd of anything like that.

Go to us.playstation.com and download the latest PSP update. Connect your PSP to your computer using a USB cable. Wait for your computer to recognize that the PSP is connected (a bubble should appear that says "New hardware detected" or something similar).

Once you computer sees the PSP, go to "My Computer" and look for the PSP. It should be called "Removable Disk" and have an icon.

Open the removable disk icon, and look for a folder called "PSP." Open that folder, and then open the folder inside of it called "GAME." If either of those two folders don't exist, create them by right clicking, clicking "create new folder," and name the folder correctly in all caps with no spaces.

Once you have opened the "GAME" folder, create a new folder inside it using the method above, only this time name it "UPDATE." Open that folder, then drag and drop the file you downloaded for the Playstation website (should be called Eboot.pbp).

Disconnect your PSP. Fully charge it, then turn it on and select "Memory Stick" in the "Games" area. You PSP should then prompt you to press start to update your firmware version. Press start, and then just let it do it's thing.

first you need custom firmware to play iso files, second the psx2psp is to change playstation 1 games into psp eboots not psp games, the iso is all you need for psp games if you have custom firmware, you just need to create a folder called ISO in the root of your memory stick and put the iso files in there

on your psp press select whise on the home screen. the change the usb: flash 1 to memory stick

1. To get firmware upgrade data . you need to download a file form PSP official website http://us.playstation.com/psp/downloads/systemupdate . File name is EBOOT.PBP ..
2. connect your pc with psp . now move to the settings and the secound option from the top press X .
3. Now click the removable disk and there would be a foldr name PSP , inside it there is another folder GAME . inside it create another folder name it as update . now paste EBOOT.PBP in that folder
4. Remove your PSP
5. On your PSP press "X" on *.**, which means an update . just install it on your psp

You can save your music into Music folder - ms0:/PSP/MUSIC/ or ms0:/MUSIC/ (ms0: is your memory stick).

You can create a new folder named "PSP" directly on the Memory stick and then create a folder named "MUSIC" in the PSP folder..



Hopefully this help..

is it modded

You need an older model PSP with update 1.54 or below. Downloading PSP games onto your PSP will void your warranty with Sony, since it is illigal and same for downloading PSP games via torrent. The copy protection on newer PSP models, PSP slim and PSP 2000 have extensive copy protection included in their frameware updates so downloading games onto the PSP is near impossible

google the name of the game/megaupload

Connect your PSP to the Computer using USB Cable, create a folder named "PICTURE" within the Memory Stick, and then copy the file into that folder.
