Install PSP Custom Firmware 5.50 Prometheus add-on

Even with 5.50 GEN-D3 installed on your PSP, you won’t be able to play some of the newer games without proper patching or plugin to help bypass Sony’s new DRM which requires 6.20 OFW. Luckily, Liquidzigong created Prometheus Module so that users with 5.50 GEN-D3 firmware (meaning COMPLETELY hackable PSPs) can still enjoy the latest game releases without any patching involved. With this guide, I’ll be showing you how to install the 5.50 Prometheus firmware add-on.

For ease of identification, Liquidzigong says you can also call this release as 5.50 GEN-D4.  For the purposes of this post I’ll be referring to this release as both 5.50 Prometheus and 5.50 GEN-D4.

Important: This only for hackable PSPs. Not sure? Read: Is my PSP hackable?

Update: The Prometheus-3 add-on is now available.
Requirements:

  • A PSP with custom firmware 5.50 GEN-D3 installed. If your firmware version is below this, please update to 5.50 GEN-D3.
  • PSP battery that’s at least 78% full
  • Download: 5.50_Prometheus.zip
  • Disable ALL plugins.
  • Back up your save files (so that if they get corrupted, you still have backups)

How to install 5.50 Prometheus GEN-D4 add-on

  • Connect your PSP to your computer
  • Extract the 5.50_Prometheus.zip to your PC
  • Copy the 5.50_Prometheus folder to X:/PSP/GAME/ on your PSP’s memory stick. (Where X is the drive that your PC recognizes your memory stick)
  • On your XMB, go to Game > Memory Stick to start 5.50 Prometheus Updater
  • Continue to install the official 5.50 Prometheus CFW when prompted
  • After all process is complete, press X. Your PSP will reboot.
  • Congratulations, you’ve just installed 5.50 Prometheus add-on on your 5.50 GEN-D3 or simply 5.50 GEN-D4.

Important: This release is currently 5.50 Prometheus v4.  Stay updated by subscribing to our feeds.
Update: The Prometheus-3 add-on is now available.
After installing 5.50 GEN-D4, How about some Free PSP Games?

Troubleshooting

In case of problems you can go back to 5.50-GEN-D3, just simply the proper XGen updater again. If all else fails, you will need a Pandora Battery to revive your PSP.

You can post problems you’ve encountered here.

Have Something To Say ?

  1. Slimy June 29, 2010 Reply

    Ay yo atma. I know this might not be the best place to ask this but i have two questions…

    1. Is there a way to play a video that is in .avi Format in my PSP??
    2. Is there a way to open a .pdf file in my PSP??

    • Z3TR0C July 4, 2010 Reply

      I know that you can convert .avi to PSP to watch it. The program is called “XviD4PSP”. So technically it DOESN’T allow .avi files to play, but rather it converts them to a playable format. As for the .pdf functionality I am yet unaware. But if you do find out please let me know…I been looking for the same thing!

      • Slimy July 6, 2010 Reply

        I’ve found a software named “Bookr” tht opens up .pdf files…
        I’ve tested it and it works…though im still looking for tht .avi one

      Try formattng your memory stick on a computer. Looks like a bad memory stick.

  4. Forte August 4, 2010 Reply

    So 5.50 Prometheus is like an update to 5.50 Gen-D3? If I update mine to Gen-D4, it should be able to play the newer games and old games right?

    • Forte August 4, 2010 Reply

      And thanks for posting this.

    • sylv3rblade August 4, 2010 Reply

      Yep. But some of the much older games (like those that came out in 3.xx era) seem to have problem with 5.50 GEN in general. At that point the only option is to juggle your firmware version (upgrade and downgrade).

    is the PSN and PS store still still blocked on this firmware?

    Hi… Uhm… 5.50 Prometheus seems to have a problem when I play YS seven. The problem is it has no sound when I play the game… Does this mean do I have to upgrade my firmware?

  7. arkminds! August 24, 2010 Reply

    yo! i have a psp 2006 and its newer version is 5.03 GEN C. it is the blue madden edition. i use chick hen whenever i restart it. can it be upgraded to gen d3 and then to 5.5 prometheus? thanks.

  8. Rance September 3, 2010 Reply

    Ah yes, this means that you have to have GEN-D3 Final installed before you can add Prometheus right? Okay, this is my real question…

    How would you know if you have D3 Final? There was another release in the Gen line saying that there was a ‘Final’ version of Gen D3. I installed D3 a few months ago, but I forgot exactly when, hence not knowing if I downloaded the Final version or the initial release.

    Is there any way of knowing? Coz D3 Final has reports of not being able to play God Eater (not specified if this includes even the KH-something plugin fix). Is there a difference in the System Info stating I have the Final version?

    • sylv3rblade September 4, 2010 Reply

      There are 2 versions of the 5.50 GEN-D3 installer, one is the xgen v5 and the other is xgen v5b. The latter installs 5.50 GEN-D3 final. If you want to make sure, just run the installer again and it will install or reinstall the final version of 5.50 GEN-D3 for you.
      Yep, God Eater works only with the prometheus module or the khbbs plugin.

      • Rance September 4, 2010 Reply

        Prometheus would’ve been a near perfect update if the older games weren’t affected. I have a couple of old games I love playing and I heard they would become incompatible with the Pro update. Also, I read that my current save games in D3 would be corrupted in Pro.

        I’ve been debating whether to sacrifice old game compatibility as well as saved games non corruptivity with updating to Pro and losing all these.

        Can you bring an end to my dilemma here? I mean, it would be of great help if I end my dilemma. Would Prometheus be able to play Phantasy Star Portable games as well as they did in D3? Would I be able to play Super Robot Wars Portable games as well in Prometheus? Monster Hunter Freedom United? Mana Khemia 1 and 2?

        I wished there’s a compatibility list somewhere on this…

    Help Please!!

    I had 5.50 GEN-D3, never had any prbs except I couldnt play MGS PW.

    So I installed this prometheus update. Now everything is great, except for my XMB menu. It is very slow. Any ideas on how to fix it so it is normal speed again?

    • sylv3rblade September 13, 2010 Reply

      Try checking the speed on your XMB, press select and check to see if it’s set to default

        Thanks man! Took me like 3 seconds to fix, now my XMB is at full speed again. I thought I was going to have to go back to GEN-D3, but its fixed thanks to your help

        • sylv3rblade September 13, 2010

          No prob :). It’s a common problem but not everyone realizes that the XMB has the fix for it :)

      You might have downloaded a “patched” copy of the games you want to play. Look for an unpatched copy instead.

    This is a great guide. Unlike many other guides this one is quite descriptive and has steps and requirements listed. Many other guides for prometheus v6 are made to “build upon” previous version guides and it ends up being very confusing if you have not been up to date with the scene for a while. Thanks a lot, keep up the good work!

      If you are then you probably downloaded a copy that’s patched for a different firmware version.

    I have a PSP Fat and just upgraded from 5.00 m336 to 5.50 GEN-D3, then installed Prometheus. I tried a downloaded demo of Undead Knights, firmware version 5.50, and after loading the PSP screen, the PSP went back to the Home screen with the message “the game could not be started.” Does Prometheus even play newer demos, or does it only work on UMD’s? I don’t have any new ones to try at the moment. I tried WWE 2008 (firmware 3.52) and WWE 2007 (firmware 2.82) and both would freeze the PSP when I tried to play them. The PSP screen would appear, the initial in game loading screen would pop up quickly, then the screen would go black and freeze, no disc activity at all. I had to pull the battery to turn it off. GTA Vice City Stories, Sega Genesis Collection, and Thrillville (all firmware 2.81) all played fine, but my game save data was corrupt and could not be used. I have games 2.60 and under and those games and their save data all work fine. So is there something I can do, or some kind of GEN update coming soon?

      Try increasing your PSP’s clock speed or try a different copy of the game file.

      • Agent 'Orange Crush' November 29, 2010 Reply

        My system info says I’m running 5.50 Prome-3. I did replace my corrupted game saves with backups and that worked, but copying didn’t work, I had to erase the files off of my PSP first. But it worked and thank you for the hint, that helped a lot. Undead Knights still won’t play, and my 2.82 and 3.52 firmware games still freeze the PSP. I don’t really care about these issues so much personally, I just wanted to see if I could find some newer firmware than the 3.52 I had been using. And maybe my info will help someone iron out the kinks for the next update for GEN.

    Hey buddy, am playin a fifa 10 since last year. But now today, when am playing it, it lags/hangs for maybe half a second or so. It making the game boring. I tried formating the flash memory, the memory stick, and then reinstalled gen-d3 and copied my saves and iso file from backup. It doesn’t solve it. I also tried deleting the saves and then opening the game, but it still lags. What do u suggest?

    • sylv3rblade January 4, 2011 Reply

      What speed is your PSP running (check the XMB menu)? Also, is this symptom present in all other games or just fifa 10?

      • Kachmen January 4, 2011 Reply

        Is XMB MENU THE SAME AS VSH MENU? If yes, Then speed is at DEFAULT. its always there! And i only have fifa 10. Music is playing fine (fifa music), and when am playing in practice mode, there is no problem. Only when i play kickoff or manager mode. Il try and diferent memory card, and the original iso backup which i put on dvd. Il update you! Thanks

        • sylv3rblade January 4, 2011

          yep that’s it. Which speed? There’s a Game Speed and VSH Speed. Try setting Game speed to 333Mhz (overclock your psp). Don’t worry though, it’ll only drain more battery.

        • Kachmen January 4, 2011

          Both speeds are set at “default”.
          Anyway, my memory card is the culprit. Its a chinese knockoff. 4gb stick. I tried a difrent one, it works ok.

          You probably have a “patched” copy of both games, try looking for an untouched copy and try patching them yourself using this guide

    Hello. I have installed ver 5.50 Gen-D3 and the file name was xgen-550gen-final. After that I tried installing pormetheus but I couldn’t launch the installation because nothing happens when I press the ‘X’ button. I press it several times repeatedly and nothing happened. After that I tried installing the firmware again but when it comes to pormetheus, I can’t install it at all. Please help. Thank you.

      Check your PSP’s current firmware version, does it say 5.50 GEN-D3?

      • Bong Kern Yih June 3, 2011 Reply

        Yup. My current firmware is 5.50 GEN-D3.

    i have now the 5.50 Gen-d4 but still when i played the monster hunter portable 3 in my psp it said “The game could not be started” plse. HELP!!!

      You likely have a patched version of the game. Get a copy that’s untouched or has been patched for 5.50 GEN-D3/GEN-D4

      • ANgelscaliber36 June 18, 2011 Reply

        The MHP3 that i downloaded is compatible with the 5.50 Gen-D3 and D4. By the way, what do you mean by untouched??

        I would really appriciate if you give me the link where you downloaded your Monster Hunter Portable 3, may be it would for me :)

        • sylv3rblade June 18, 2011

          Untouched means it’s the original dump of the UMD, no modifications etc.
          Currently uploading :)

        • ANgelscaliber36 June 18, 2011

          Uploading the MHP3??? if so THANK YOU VERY MUCH!!!!

        • ANgelscaliber36 June 18, 2011

          If you’re finish uploading it just post the link and i’ll download it :)

    I have a PSP, 1000 fat and i started at 5.00 m33-6, i then went to 5.50 GEN-d(full), and finally 5.50 Prome-4. When i start an iso it loads the boot screen and the psp turns off. Help please im going on holiday and i need itt!!

    • sylv3rblade August 4, 2011 Reply

      Does this happen to all your isos? Regardless, just the prometheus module with the newer version here.

    my psp just says 5.50 Prometheus just that no GEN-X, is it safe to update straight to 5.50 prometheus-4? and is prometheus-4 the same as prometheus gen-d???

    • sylv3rblade October 21, 2011 Reply

      Promethues-4 is the latest version of the prometheus module, you have the first release. Yes you can upgrade to prome-4

      • iKey October 21, 2011 Reply

        which do i download? for 5.00 m33, for 5.03 GEN-C, or 5.50 GEN-D3??

      • iKey October 21, 2011 Reply

        so you mean i can just go to 5.50 prome-4 straight? i dont have to go from 5.50 prome –> diff. version –> 5.50 prome-4?

        • sylv3rblade October 21, 2011

          Yes but if you want the more careful route, reinstall 5.50 GEN-D3 using this post then install prometheus-4 for 5.50 GEN-D3.

    dude i have 5.50 GEN-3 and i disabled all plugins and then i successfully installed that 5.50_Prometheus.zip.

    i was trying that WWE all star. i got stuck on the option of saving data for the game so i turned it off.

    the problem is that it just wont start up anymore as in nothing on the screen just the green light power is on.

    i tried to turn it on again and go to hard settings by pressing the right top button and holding the power button up. Still nothing.

    HELP.
