Install PSP Custom Firmware 5.50 GEN-C

PSPGen and GENyUS has just released 5.50 GEN-C. If you’re thinking *yawn*, not another incremental update then you’re sadly mistaken as 5.50 GEN-C will let you play 5.55 and 6.00 games straight from the ISO :D. Sounds like quite a deal doesn’t it?

No more decrypting, no more patching and no more rebuilding. Well that is the only case IF you have a HACKABLE PSP (Is my PSP hackable?). For PSP-3000 / PSP-2000 TA088v3, it’s still the Game Decrypter method for you.

Important: GEN-C is still buggy and is causing a lot of problems. I recommend installing 5.50 GEN-D3 instead.

Important: DO NOT attempt to install this on PSP-3000 / PSP-2000 TA088v3. YOU WILL BRICK YOUR PSP IF YOU DO.


  • Any PSP with custom firmware installed 3.71 M33 or above. 5.00 M33-6 is the best bet for the XGEN Updater to work.
  • PSP battery that’s at least 78% full
  • Download: XGen Updater
  • Disable ALL plugins.
  • Back up your save files (so that if they get corrupted, you still have backups)

How to install 5.50 GEN-C using XGen Updater

  • Connect your PSP to your computer
  • Extract the XGen Updater to your PC
  • Copy the PSP folder and the 550.pbp file to the root of your memory stick
  • On your XMB, go to Game > Memory Stick to start XGen Updater
  • Select Flash install CFW 5.50 GEN-C
  • After all process is complete, press X. Your PSP will reboot.
  • Congratulations, you’ve just installed 5.50 GEN-C

Update: PSPGen and Yoshiro’s explaination for 5.50 GEN-C’s issues: (Translated from French)

First we present our apologies for this release that posed more problems than we expected. To be very frank, in our tests made in the same manner as other times, we had satisfactory results, but several factors intervened between the announcement of the online one. We will try to explain the why of how this release cursed.

Firstly, the original version that was being posted was well prepared for this announcement and we had given 24 hours of additional testing to verify that everything worked well. This first release does not launch the protected games but all games 5.55 +. In the process, Yoshihiro out how to counter the protections we have decided to announce and release in the edit function. So this is where we fished for if everything worked in our tests, it is found that certain protections of our CFW have come to panic under certain conditions and also depending on the model of PSP. Moreover, to avoid (too much) delay the release, we dropped the baby without giving her a test period of time. Accept our apologies for this.

In our defense, there are several types of errors, some of which we are not attributable to:

* You have a black screen by launching the updater
You are in Custom Firmware 5.50GEN-B and not in B2. It was enough to qse B2 therefore to resolve the concern.
* You have a semi brick ( “I have the clock …”)
You had left a personalized theme and therefore it was enough to format the flash1 via Recovery menu. Do not have a personal theme during a flash console is part of b and ba and we had forgot to report it. Nothing serious, however, because the Recovery remained accessible and / or restart without his MS usually enough to break the deadlock.
* You bricked your console
The installer of 5.50GEN has no CFW our bug and can not be directly responsible for that. Everything is working 200%, you can be sure Clearly, note that if you have bricked is probably due to a failure of your nand that would have occurred at any other attempt to flash your console including an official.

Note that GENyUS and Yoshihiro currently working to ensure that these mistakes are forgotten as quickly as possible and we will post the Custom Firmware 5.50GEN-D when everything will be validated and verified. A priori, this should not be long and, again, be assured that we are sorry for any panic.

If you still want to proceed to installing 5.50 GEN-C, continue reading below.

I’ve also updated the post for the XGEN Updater with this information.

    • dllhost October 19, 2009 Reply

      Don’t write such things since you are not have every PSP in the world 😉
      For most ppl this FW is headache and you have just been lucky that everything is work ok.

    • sylv3rblade October 19, 2009 Reply

      Wait… so you got it working properly?

      • thinkpad October 19, 2009 Reply

        yes, it needs to install and after that, go in biod and reset flash or something of that ( it is there). After thar is works, and all games are working( but thut is my case, i don`t now if it will work n your psp)

      • thinkpad October 19, 2009 Reply

        anyway if tou know to reflash the psp you can try my sugestion 😉 and one question for me.. how do I reflash my psp if i need it?

        • sylv3rblade October 19, 2009

          If your PSP is working properly with CFW you can use tools like the XGEN Updater or the Hellcat’s recovery tool.
          If your PSP is semi-bricked, just pop an EBOOT.PBP of the firmware you want to reflash in PSP/GAME/RECOVERY/ and boot with the pandora battery.

    p.s: software=firmware.. i`m not british :))

  11. keiji October 20, 2009 Reply

    i just found out that if after the installation psp starts but the XMB doesn’t appear and then shuts down, all you have to do is go to the RECOVERY menu, go to ADVANCED, and select the option that says FORMAT FLASH1 AND RESET SETTINGS…

    everything will be back to normal, and you’re SYSTEM INFORMATION will say 5.50 GEN-C

    GEN-C is very buggy…i recommend waiting for 5.50 GEN-D

    • sylv3rblade October 20, 2009 Reply

      I’d recommend it too. I was running a custom theme so poof! Anyway I’ve added the disclaimer.

  12. Rick October 20, 2009 Reply

    So i tried this so i could play SC4, no luck, for some reason when loading the battle where it shows the 2 characters it loads for a few seconds then completely freezes and shuts off. Any Ideas??

    • sylv3rblade October 20, 2009 Reply

      There’s a hacked version of SC4.

      • Rick October 21, 2009 Reply

        I have tried both the hacked and unhacked, and even took the unhacked and did it myself. No Luck

  13. zetagear October 21, 2009 Reply

    shutdown ur psp then go to Recovery Mode (Hold R+switch on) go to advance menu then Reformat Flash Memory.

    • Rick October 21, 2009 Reply

      I had to do that when I upgraded anyhow cause I had a custom theme and it didn’t let the game run right after.

      • sylv3rblade October 21, 2009 Reply

        Hmm that’s odd. Have you tried switching ISO mode?

  14. MegasBahamutAlchemist October 21, 2009 Reply

    Or, in the case for semi-bricked PSP, instead of doing all that, just go do Recovery Menu -> Advanced -> Format Flash1 and Settings.

    That’s what thinkpad tried to say. No one may have every PSP in the world, but the code for the firmware is only one, and shouldn’t have problems with any supported PSP.

    Just tried it and it works, now I jsut need to reconfigure the settings and Wallpaper

    • sylv3rblade October 21, 2009 Reply

      Looks like formatting the flash is really the solution for most semi bricks. I’ll add it up to the disclaimer.

  15. guy October 25, 2009 Reply

    Hey, when you’re updating to GEN-D from B2, do you have to update to C then D? or can i just go straight to D from B2?

    • sylv3rblade October 25, 2009 Reply

      you can jump from B2 to D. You can ignore GEN-C.

    pls. help. i have a psp-2000 hacked psp with 5.00 M33-6 firmware. thanks…. ive gt the file 550.PBP from XGEN but were do i put it??? thank you

    • sylv3rblade November 1, 2009 Reply

      on the root of your memory stick (i.e. if your memory stick is read as E: copy it so that the path of the file is E:550.pbp)

  17. mike January 10, 2010 Reply

    it very misleading when they say root you think MP root but really it just the main area of memory stick IE if you click on drive before you enter any folders that is were you leave 550.php not in any folders

    • sylv3rblade January 10, 2010 Reply

      That’s actually the correct term when you’re referring to the just the drive letter. If your computer detects your PSP as drive E: then the root folder is driver E:.

  18. ajak February 23, 2010 Reply

    what the meaning of this —
    Copy the PSP folder and the 550.pbp file to the root of your memory stick??
