Download PSP 5.51 Update: How to Update PSP to Firmware Ver 5.51


It’s easy to update/upgrade the Playstation Portable (PSP) 3000 system software to firmware version 5.51. There are two ways to do a PSP 5.51 update – regular file download and network update. We did an update on our pink PSP 3000 using the network update procedure since our place has wifi.

Why did we choose network update in updating our PSP firmware to ver 5.51? It’s much simpler. Here is a quick tutorial on how to carry out PSP 5.51 update using Network Update (Method 1):

  1. Go to Network Settings to configure your PSP WLAN by setting up an access point.
  2. Under Network Settings, it would be best to choose Automatic to simplify the process. Your PSP console will search for any wireless network available nearby.
  3. To Update System Software to the latest 5.51 firmware version, Go to Network Update. Be sure your battery is full because the update will fail if you turn off you PSP console or if the unit shuts down due to lack of battery power.

Method 2: Download File To Update PSP 5.51 Firmware Using a PC. If you prefer to update your console using the download method, here are the simple steps in doing this:

PSP 5.51 Update: Network Update and File Download Method

PSP 5.51 Update: Network Update and File Download Method

  1. Create a folder in your Memory Stick Duo named “PSP“, under this folder, create a sub-folder named “GAME“, under this sub-folder, create another sub-folder named “UPDATE” (Note: all folders name must be CAPITALIZED)
  2. Download the PSP 5.51 update file via this link: http://du01.psp.update.playstation.org/update/psp/image/us/2009_0611_148d2a024741df54eacabbc79d9f3014/EBOOT.PBP
  3. Save the file as “EBOOT.PBP” to your desktop then inside the UPDATE folder mentioned above.
  4. To start the Update process, Go to Game -> Memory Stick and hit the Enter Button (symbolized by the Cycle symbol). Always remember, during the update process, your battery should be full in order to avoid any problems. The udpate process will take about 10 minutes.
  5. Verify that your PSP 5.5.1 update is successful by going to the Settings -> System Settings -> System Information menu. From there you will be shown if your PSP version. If it shows System Software Version 5.51, then your PSP update is successful! However, don’t expect too much from 5.51. We have seen no significant changes except for some “system software stability” issue with previous versions.

      @ace, This might help.. go to system setting, and then restore default settings.. after that go to photo, and select memory stick, press it… ur psp should be able to read ur download games. update me if these steps work on ur psp.

  11. bagoong says:

    to all u guys having problem with 5.5xx firware, never update with urself, this will just lock ur psp’s on playing umd’s and totally not for iso’s… i advice that take ur psp’s to some electronic shops that cater psp upgrading coz they know how to jailbreak those firmwares and ur psp just to make it in latest version and running those iso or downloaded game files. just a little complement of paying 200-300 PHP with ur psp in full function rather than it becomes useless at all.

    After I updated to the software version 5.51, my saved games in the psp are not shown, it says” There are no games”, but it is still saved in the memory stick. Therefore, I can’t play the games in the psp. Why is this happening and how do I solve this problem? we have the same problem as Enen!
    pls help me my psp is useless w/o any games…

  68. Tyrone says:

    Hi I have been having issues updating to the new firmware when I go to network update on my psp I am able to download the new firmware just fine but when I run it on my psp the psp starts over as it should and goes to a black screen for about 10 sec and then I get an error message that states “the data can not start data is corrupt”

    • Sid says:

      Try formatting your memory stick and then running the network update to download the update file. You should then have the option of running the update file when downloading is complete by pressing X or running it later from the games menu.

  69. Enen says:

    • Murio says:

      Did you already solve your problem?? Well, I just upgrade my psp to 5.51 but I have the same problem as yours, it says “there are no games”?? Do you already know why??? pls help, thanks much..

      • CAMERON CRUZ says:

        @Murio, the reason your psp is not showing the games is that ISO or CSO games are not compatible with the update the highest the games will be able to be played is 5.00 VERSION software. i hope this answers your question.

    • Farayola says:

      when you save your games make sure it is saved in the second folder of the game, course you have something like iso you open it, you see another folder named GAME save them their and you will be able to play your saved games, try it if it works then you can send it to another person that is having the same problem, but if it dosent work, mail me the steps you took, and i will know how to help you. thank you very much it’s my pleasyer helping you

      • Coco says:

        Hi Farayola,

        We did everything you wrote on the post and still not working with the downloaded games!!! please, help us!

      • Lhangskie says:

        Hey Farayola,
        what you said is just a couple of cramp. psp 5.51 firmware update totally doesn’t work. if anyone if you wishes to update your psp using this file, i’ll advice you not to. coz’ after updating your psp using this file, your psp will become totally useless. i suggest updating your psp using the Custom Firmware version 5.5 GEN-A. then update it using the Custom Firmware version 5.5 GEN-B

      • shivam says:

        @Farayola, i have 5.00 version and 1001 psp series,and my memory stick is mem stick pro hg duo and when i put my games (fifastreet 2) in iso and try to play it says their is an error.i am downloading this 5.51 upgrade and hope then i can play (fifastreet 2)
        pls reply, thanks

    • Lhangskie says:

      have you had any luck yet? im having the same problem like yours. this psp 5.51 version really suxx. if you have any fix please do email me how to troubleshoot or downgrade my psp version.

      • Fahmii says:

        guys,i have the same problem, and i’m fixing it soon,simply go to a psp store or whatever,tell him to downgrade PSP firmware, or you can buy a pandora battery

    • Rejay says:

      @Enen, Because 5.51 SUCKS!!! it doesn’t have a CFW.. if there is no CFW you can’t play games!!

    • Khrisna says:
