Install 6.31 Hen + Prometheus ISO loader on your PSP

PSP owners with 6.31 OFW can now have cfw installed courtesy of the 6.31 Hen, 6.31 hbl by wololo and the Prometheus ISO loader.  Note that if you’re on 6.20 OFW, follow this guide instead.

Requirements for 6.31 Hen and Prometheus ISO

Important Note: if you’re having problems with installing 6.31 Hen, try out the guide on installing the Signed 6.31 Hen PRO

Installing 6.31 Hen and Prometheus ISO loader on your PSP

  • Extract the Mina no Sukkiri Demo onto your PC
  • Copy the folder (NPJG90047) into x:\PSP\GAME (x is your memory stick or the PSP Go‘s storage)
  • Extract the 6.31 file onto your PC
  • Copy it’s contents directly onto your PSP. This contains both the homebrew loader and the exploited save data.
  • Extract the Prometheus ISO loader onto your PC
  • Copy the extracted folder to x:\PSP\GAME (x is your memory stick or the PSP Go‘s storage)
  • Extract the Light VSH menu file for your PSP model on your computer.
  • Copy the plugins folder directly onto your memory stick or the storage of your PSP Go.
  • On your XMB, Run the Mina no Sukkiri
  • Select the second option to load the save exploit.  This would automatically load Hen onto your PSP and it will revert back to XMB
  • Once you’re back on the XMB, press “select” to make sure the Hen menu displays correctly.
  • Follow this guide on how to install the Prometheus ISO loader on your PSP: Installing the Prometheus ISO loader on your PSP.
  • Enjoy your Free PSP Games :).

Update: Added installation of Light VSH Menu.  Why is it at the start of the installation process?  So you can immediately load it after installing the 6.31 Hen.

Important Note: Be sure to check the Prometheus ISO loader compatibility guide
Important Note: You need an ISO folder in your PSP’s memory. Simply create one and dump your PSP ISOs/CSOs there.

If you’re experiencing problems with loading HEN (symptoms include blue screen, freezes and turn off automatically), follow the tip below:

  • Just as HEN started to load you just ticked the power button .. your PSP will go to standby mode … then switch on the power button again Your PSP booted up hen.
  • Backup your savegames and PSN content, and reformat your card.
  • Turn off UMD-cache


If you’re not on 6.31 OFW, follow this guide on how to upgrade your PSP to 6.31 so you can install 6.31 Hen: HowTo: Upgrade your PSP to 6.31 OFW.

Have Something To Say ?

    got psp 1000

    wht shld i do

  3. SkiitZo January 5, 2011 Reply

    I just tried to use these files on my PSP 3001 OFW 6.31 and it doesn’t load the HEN.
    I tried pushing the Select button to see if the VSH menu would appear, but it didn’t.

    Is there something I did wrong by chance?

    • sylv3rblade January 5, 2011 Reply

      Hmm odd, I tried it with my friend’s PSP and it worked. Hang on, I’ll check the files.

    • sylv3rblade January 5, 2011 Reply

      retried installing on another PSP and it worked fine. What PSP do you have? Did it revert to the XMB after loading the save game exploit?

  4. dunno January 6, 2011 Reply

    can you send everthing i need to know to my email + download link abot downgrade version 6.31 and hen [email protected]

  5. Dboy January 6, 2011 Reply

    ok so tried the new hen and as it loads the save game it goes to a black screen where it brings up some information about the patch and then goes to another black screen where it says “WARNING MEMORY LEAK” and back to XMB yet when i press select still nothing.
    What could I be doing wrong?
    Any help?

    • sylv3rblade January 6, 2011 Reply

      Try checking your system settings to see if your psp has loaded 6.31 Hen.

  6. Dboy January 6, 2011 Reply

    Ok so it doesnt say 6.31 Hen it says 6.31 PRO which i dont think it did b4. now prometheus loads up and works fine. i tried to put some .iso and .cso on but it cant find them. so maybe i put them in the wrong folder?

    • sylv3rblade January 6, 2011 Reply

      place them in an ISO folder on your memory stick (if you don’t have one, create it)

  7. wikileaks January 7, 2011 Reply

    hello sylv3rblade, can plase make all in one pack (zip/rar) with the dame demo and everything done. i mean just format memory extract and load. then everything should run and fun. i guess. let me know what u think about it. btw same pack but for 6.35 cya.

    • sylv3rblade January 7, 2011 Reply

      Great idea. I’ll repack the files into a single download for each of the firmwares for HEN.

      • wikileaks January 7, 2011 Reply

        =] i let me know when its done. btw i try it, but i think i missing something, dunno what but i just tryed twice. no luck, it restart i press select and nothing changed. ummm rare i guess. well =] btw add prometeus iso loaded in repack.

        • sylv3rblade January 8, 2011

          uploaded and edited the guide.
          I’ll updated the trouble shooting guide as well

  8. Dboy January 7, 2011 Reply

    Ok so i put them into a created ISO folder. and moved it onto memory stick, but they still dont show up when i open prometheus. i put the ISO folder into a few different folders to see if that would work but they sitll dont show. The ISO’s i put in FF7 Crisis Core and Yu-gi-oh. I have multiple folders that show up on my PSP. I tried to put the ISO folder into PSP/GAME/ folder.

    • sylv3rblade January 7, 2011 Reply

      The ISO folder should be in X:\ISO where X is your memory stick.
      This means that if you have a game in there, it would read as X:\ISO\somegame.iso
      Also take note that the files in there should be in iso or cso format.

      • Dboy January 7, 2011 Reply

        Ok awesome. Found the games. Thanks. Problem is now when i go to load them nothing happens. screen goes black and I have to reset and start all over. Sorry to be such a pain but any ideas?

          If you can, take a screenshot (via a plugin) of your system software version 🙂

        • Nadine January 7, 2011

          i got 6.31 but sorry to say ive tried it but not all the games work why ? i have a game that crash and then the psp turn off why ? its ratchet and clank ? and whats iso mode ? m33 driver ? and the second one ? whats the difference?

        • sylv3rblade January 8, 2011

          m33 driver is used for older games. The prometheus ISO loader (and all the prometheus modules) are meant to decrypt newer games and seem to have problems with older ones. We can thank sony for that :/

        • Nadine January 8, 2011

          oh okay ratchet and clank crash when i open it all other 9 games work .. i aslo get a memory leak but it works like a charm will there be an update to iso loader to run and be compatible with all games ? hmm some of the pictures above is not the same for me i dont get a menu when i click select it says i have 6.31 pro , whats the difference between Install 6.35 Hen + Prometheus ISO loader on your PSP is it updated to fix issues like that ? such as crashes … black screens.. crash when i pause and continue game…

        • Nadine January 8, 2011

          have anybody tried it with ratchet and clank size matters ? it seems to not be working ive tried 12 more games and all they work except this ? also will there be an update for promethious iso loader ? where can i find promethious iso loader main page to see the updates ? is there 0.2 ? i have 0.1

        • sylv3rblade January 9, 2011

          No updates yet, I’ll update the post and do an announcement on the front page for the next release of prometheus.
          For starters however, I’ve listed games compatible and not with the Prometheus ISO loader:

        • Nadine January 9, 2011

          okay im waiting for the update sorry im stupid where is the front page ? do you mean that page ?

        • Nadine January 9, 2011

          oh hey mercury Confirmed not working with Prometheus ISO loader ?? it worked on my psp go

        • Nadine January 9, 2011

        • sylv3rblade January 9, 2011

          Front page is on just 🙂
          Think of it as news update

        • Nadine January 9, 2011

          hey i see under the promethious iso loader ratchet and clank ? how are you able to play it ? its not incomptatible with iso loader ?

        • Nadine January 9, 2011

          did you use some sort of patch on it ?

        • sylv3rblade January 9, 2011

          umm it’s under confirmed not working :/

        • Nadine January 9, 2011

          i found openidea-iso-loader-0-2 is it safe ? will it brick my psp ?

        • sylv3rblade January 9, 2011

          Open idea is still a WIP and quite behind Prometheus in terms of compatibility :/

        • nadine January 10, 2011

          hmm theres something wrong with you compatibility list please change mercury to working because its confirmed working on my psp go if you want i can make a video 😀 but please as soon as you update promethious iso loader send a message to my email [email protected] and give me the link ..

        • sylv3rblade January 10, 2011

          Yes. Just dl the 6.31 Hen pack or the 6.31 Hen Complete pack, extract and copy it over the existing files on your memory stick. You should see the PSloader on your XMB.

        • Adi January 10, 2011

          Not a prob. Just a reminder, development on the 6.31 seems to be dead so in the future, the likeliest course is to upgrade to 6.35 :). For now, have fun with your new cfw.

        • sylv3rblade January 24, 2011

          don’t worry, the guide I linked you to teaches you how to upgrade to 6.35 specifically. The only way you might update to 6.37 is by using the Network Update.

        • sylv3rblade January 24, 2011

          also, I’ve updated the guide on this post so you can update to 6.31 if you choose that over 6.35 🙂

      There is currently no public exploit that’ll allow you to downgrade from 6.38 or install Hen to run your games on it. However if your PSP is hackable, you can use a Pandora Battery to downgrade it. Check this guide here:

          the XMB is the menu of your PSP. As for the Pandora battery issue, I suggest subscribing to our feeds and wait for Total_Noob’s release of a Hen for 6.38.
