PSP Custom Firmware 5.00 M33 is Released

Custom Firmware 5.00 M33 has just been released.  Dark Alex completely skipped 4.02 and released 5.00 M33.  Interested in the changes?  Read the PSP 5.00 OFW changes.  The most welcome change to 5.00 is the full QUERTY keyboard.  No more cellphone like input for us ^_^.

Note: If you’ve already install 5.00 M33, you can skip to it’s patches on the next page.  The latest patch is 5.00 M33-6.

Important UPDATE: If you are having trouble playing the latest PSP Games, you may want to install the Prometheus-4 module or use the ISO Tool Patching guide. OR you may want to update to 5.50 GEN-D3 🙂


How to install 5.00 M33 CFW on your PSP:

  • Extract the 5.00 M33 installer files to your computer.
  • Copy the Update folder to X:/PSP/GAME/ on your PSP’s memory stick.
  • Download the official 500.PBP.  Rename the EBOOT.PBP to 500.PBP before proceeding.
  • Copy the 500.PBP to the directory; X:/PSP/GAME/UPDATE on your PSP’s memory stick.
  • Disconnect your PSP
  • Run 5.00 UPDATE from under Game on your PSP’s XMB
  • Press X if asked to correct idstorage keys
  • Continue to install the official 5.00 SONY when prompted
  • After all process is complete, press X. Your PSP will reboot.
  • Congratulations, you’ve just installed 5.00 M33


If you haven’t successfully installed the 5.00 M33 firmware then you can’t proceed here since these are just subsequent patches.  Read the guide on How to install 5.00 M33 on your PSP above or if you have official firmware, post a comment and let’s see if I can help you out.

If you want to upgrade your 5.00 M33-6 then turn to the next page.

    you don’t need to reinstall custom firmware on your PSP just because you’ve bought a new memory card. Just copy over ALL files and folders from your old memory card into the new one.

    you really need your cfw to be at least 4.00 m33 or 4.01 m33 otherwise you risk bricking your PSP

    hey im on 4.01 m33-2

    i want to update to normal, Sony firmware, not hacked

    can i just click network update and it will work? or will that crash my psp?

    • sylv3rblade December 26, 2008 Reply

      You can manually update to the official firmware. If you use network update on 4.01 M33, it’ll update you to the latest CFW not OFW.

      Are you sure it’s a PSP-2000 model, not a 3000?

    • sylv3rblade December 26, 2008 Reply

      you need to use a Magic MS to install custom firmware on it.
      I’ll try to create a guide for that in a few days but for now, it’s best if you can ask a friend to help you out.

    What do I need to do first before I can upgrade the OFW? Thanks in advance.

    • sylv3rblade December 31, 2008 Reply

      first off, what model of PSP do you have.
      Is it a PSP-3000 or a PSP-2000?
      If it’s the latter, do a check on what model your motherboard is.

    • sylv3rblade December 31, 2008 Reply

      yep it’ll work regardless of your PSP’s localization. And yes, you need to install M33 before proceeding to M33-4 since M33-4 is just a patch.

  37. AndreX December 31, 2008 Reply

    PS before I can upgrade my psp with the m33-4 i MUST install the m33 or I can skip this step? ^^

      5.00 M33-4 is the latest release of custom firmware.
      There’s a 5.01 version for the official firmware though and I’m not sure if that 5.01m33-4 is a legit version of the CFW

    • sylv3rblade January 4, 2009 Reply

      Network update only works for 3.90 M33 and above. If you do use Network Update on your 3.71 m33, it will install the official firmware and you’ll loose access to free games. Update to 3.90 M33 first or go directly to 5.00 M33

    Yeah, nice! But, if you have original software (no customs software like 5.00 m33) yours PSP never Brick!! With hacked versions PSP can stop working after some time! I know what im talking about… You are not SONY that can creates software that never stop working… There always is RISK, isn’t it sylv3rblade???!

  62. sylv3rblade January 26, 2009 Reply


    actually, even just upgrading original firmware there’s a possibility that your PSP will get bricked since you’re still rewriting the firmware.

  63. ishralene09 January 27, 2009 Reply


    sylv3rblade is right. There’s still possibility that the PSP will brick even when upgrading your original firmware. The “brick” thing doesn’t have anything to do with what firmware you have, but on how you do the upgrade. Since upgrading requires flashing the ROM, any wrong move(like running out of power or accidentally turning off the PSP) will cause the flash process to be interrupted, leaving you with I don’t know, a BRICKED device. So yeah, and it also works that way for other devices, unless you can device a method to flash the ROM again, then things are fixed.

    “You are not SONY that can creates software that never stop working”

    WTF? Even the X360 has the “Red Ring of Death”. It’s not the software man, it’s the hardware. So apparently you DON’T know what you’re talking about. Software will work as long as there is a hardware that it is compatible with.

    Just sharing my two cents.

    I admit though, that moving from OFW to CFW is quite risky, but with technological advancements such as the Pandora battery, the risk is manageable.

      What model of PSP do you have? If you have a PSP-1000 you need a Pandora Battery to install Custom Firmware.

      If you have a PSP-2000, what motherboard do you have? A shop can check it out for you and install the custom firmware or you can look it up yourself (you need to peek through the UMD door and read the model number on your PSP’s motherboard). You still need a Magic Memory Stick before proceeding.

    hi, jst a few days ago i upgraded my sister’s silver psp to an official sony updater version 5.03 with d EBOOT.pbp

    unfortunately i ddnt know it wld wipe out the modification dat it alrdy had last year to play downloaded games.

    i found a website and tried to ask for help this was my post..

    “hi, my sister’s silver psp was modified last year and that it was working fine with downloaded games.

    unknowingly i tried to update d version by downloading a higher version update from sony official psp update software website and it successfully updated to version 5.03

    it ddnt mess the usual capabilities of the silver psp to display pics, play music & videos, and PLAY UMD games.

    but wen i tried looking for the downloaded games in the memstick it doesnt display the games i have saved in the memstick.

    how can i modify it to play downloaded games again?

    i ddnt know dat if i updated the version with an official updater that it wld wipe out the modified features it had last year to play donwloaded games.

    its expensive to have it modified again thru a guy who does it at the mall.

    can i install ur custom firmware to fix the new sony version 5.03 update without messing things up?

    i alrdy felt bad for messing it wen i updated with a new official sony update by overwriting the old modified state that she paid for to have it done at the guy at the mall who sells psp accessories..

    so before she left this morning i let her borrow my blue psp (which i had paid a guy at the mall to modify it) jst for the meantime until i get her silver psp back to playing downloaded games.

    i want to modify this silver psp but im afraid i might kill d damn thing!

    please help me =(

    Posted on April 4, 2009 5:43 AM ”

    you know wat hako replied?!?!?


    that was so disappointing really.

    i went back 2d mall and asked for d guy der 2modify it again and he tried to use d pandora battery & his memstick but the thing is it wont start d modifying thing, jst a BLANK BLACK SCREEN.

    he said he needs to open it up must b somthng wrong w/ memory or something. he said dat wld take longer to fix and wld cost me Php800!!!

    can i still do the modifying on my own with d help of ur instructions? or shld i let the guy at the mall try to fix it and spend Php800?!?!

    HELP!!!! :'(

    and it came with d box of DAXTER limited version, my mom bought it there in cali and shipped it to us last year.

    is there any hope i cld downgrade it again? or shld i jst let d guy at the mall attempt to fix it?


    • sylv3rblade April 9, 2009 Reply

      If it already had custom firmware installed (and since the Daxter Pack is a PSP Slim) you just need a magic memory stick to install custom firmware.

      Although since you mentioned that you have little idea of what’s going in, it’s better to cough up the 800 pesos than brick the PSP.

    • sylv3rblade April 18, 2009 Reply

      Try entering the recovery menu and do a hard reset on your PSP. If it doesn’t work, you may need a universal unbricker and reinstall custom firmware again.

      It’s important that you remember that you shouldn’t, under any circumstance, turn off your PSP when patching firmware. Otherwise you’ll brick it.

    • sylv3rblade May 4, 2009 Reply

      It’s incorrect because you need to install 5.00 M33 before patching to 5.00 M33-6. Didn’t read the instructions *sigh*

    Do we have to install these patches in order or can we just start with 5.00 M33-6 after I install 5.00.

  104. sylv3rblade May 6, 2009 Reply

    After installing 5.00, you can jump to 5.00 M33-6. The other patches are there since I’ve updated the page whenever there’s a new release.

    thanks for your post it really helps a lot.

    have not used my phat psp for a while now but was looking to install custom firmware onto it. my intention is to play the Final Fantasy Series on the psp.

    i am currently running official firmware 2.5. just wanted to make sure i go about the right way in installing custom firmware.

    – my understanding so far is that i need to acquire a Pandora battery and then use it in combination with a magic memory stick which will then install custom firmware to my psp.

    – in a next step i would theen need to install the latest M33 firmware

    Could you confirm if this is the best approach coming from official firmware 2.5?
    Do I definitely need a Pandora battery to install custom firmware (don’t have one at hand)?

    thanks a lot

      Yes. If you get an error that you can’t delete the files then it’s probably a problem with the memory stick. Backup your files (save, music, games, themes, plugins) and reformat your memory stick.

    If you’ve already installed 5.00 M33, you can jump to 5.00M33-6. The rest is for archiving purposes (hence the reverse order)

      In your case, I’m thinking your PSP is already a permanent brick. If you can still access the recovery menu (turn off your PSP then turn on while holding the R button) then you can still try to recover it using a Pandora battery. If you can’t however then you need to buy a new PSP.

    The directions told me to go to the recovery menu, go to advance, go to flash0, the open the VSH folder, open the resorce folder, drag and drop files to folder and yes to overwrite. I should have backed up the files but i thought the directions where very simple. the files it added where : background, gameboot, system plug in.rco, system plugin fg.rco, coldboot.vag, topmenu plugin.rco and itno.pgf Can i copy these files from somewhere and reinstall? They are not on the memory card they are on the psp i belive.

      You don’t mess with anything in flash0. I’m sorry to say that you have a semi-brick (You can enter flash0 but not the XMB) If you have a pandora battery, you can flash your PSP back to cfw.

    I did everything as it was written on the guide, and installation was sucessful. I got 5.00 M33, but then a screen appeared saying in various languages that the settings were corrupted. It didn’t seem anything serious because after that I inputed the settings again and everything seemed fine. I didn’t checked if the games were working at the time.
    Then I installed the 5.00 M33-6 patch.
    I deleted everything in the UPDATE folder after the major update, and only then pasted the patch eboot along with the 500.pbp, thinking it would be necessary. It installed fine again. I deleted the entire Update folder after this.
    Then I checked the games. Everything seemed fine again. I chose one and started. Then the problems start: I can’t start any game! It returns me to the XMB with the error 80020321. Only the emulators work!
    How can I solve this? i’m kind of scared it won’t work again. I’m positive it worked, in System Settings it says 5.00 M33-6
    Thanks in advance!!!

    PS: I disabled the plugins too.

      Sorry for double post.
      – I had 4.01 M33-2 before this.
      – The sound that some games present when your are choosing a game in XMB don’t play.

    • sylv3rblade August 29, 2009 Reply

      Press select on the XMB and check what option for UMD ISO Mode you have selected:

      Also, are you sure you’re putting the games in the right folder? The ISO/CSO files should be placed on an ISO folder inside the memory card.

      But thank you anyway for answering and for the guide, too.
      You seem a really cool guy, replying to all the questions. I wish there were more like you!

      Just one more question: Is this m33 version still the newest?

      Thanks again.

        geez I post a lot but I have another problem…
        After all this I tried to play Rock Band but the save is corrupted!!
        I backed them up before updating. I tried to play once but the load failed. Then I replaced the saves in the memory stick by the ones that were backed up just before the update, but it says they are also corrupted!
        What’s happening?
        Thanks in advance!!

        • sylv3rblade August 29, 2009

          Hmm… I think it’s because Rock Band was released AFTER the official 5.00 firmware was released. Although I’m not sure why your saves are still corrupted even if you copied the saves from before the update. I’ll look into it.

      • sylv3rblade August 29, 2009 Reply

        Well I do what I can to help out. 😀 I try to answer everyone but I end up getting tired of people asking the very same question by the guy before them >_>.

        Anyway, to answer your question. 5.00 M33-6 is the latest release by dark alex. The latest custom firmware version (the one with the highest official firmware equivalent) is 5.50 GEN-B

    • Tomas August 29, 2009 Reply

      do you think that it’s worth upgrading to
      5.50 GEN-B?
      how hard it is to upgrade, relatively to upgrading 5.00 M33?

      • sylv3rblade August 29, 2009 Reply

        Well, the only feasible reason for me to install GEN-B is if I want to access the PSN. Personally though, I’d stick to 5.00 M33 since it’s more stable.

        Upgrading to 5.50 GEN-A then GEN-B is simple as pie :D.

    • Tomas August 30, 2009 Reply

      ok thanks.

    Alright I have a PSP-1007 and I’ve gotten the chickHEN 5.03 R2 firmware running just fine, it’s the steps after that I’m having trouble with. I’ve tried doing the chickHEN > CFWE 3.50 (nothing happens, PSP just restarts and the firmware is still chickHEN), chickHEN > 5.03 GEN-A (same as previous), and chickHEN > 5.00 M33 (screen just hangs at the ‘Please wait’ step).

    What am I doing wrong?

      That’s because your installing the cfw for PSP-3000s. Read this guide instead

        Thanks for replying. I actually discovered my mistake soon after I posted and used Hellcat’s recovery but ended up bricking my PSP (lol), so I just created a Pandora battery and MMS and I got 5.00 M33-6 working fine. The only downside is a I need a new battery now =\, lol.

    # Copy the Update folder to X:/PSP/GAME/ on your PSP’s memory stick.
    # Download the official 500.PBP. Rename the EBOOT.PBP to 500.PBP before proceeding.
    # Copy the 500.PBP to the directory; X:/PSP/GAME/UPDATE on your PSP’s memory stick.

    This doesn’t make sense are we effectivley renaming the eboot file that is already in the update folder or are we replacing it – as renaming it and then copying an identically named filie over it is replacing it…..don’t get this bit as it seems to contradict and may explain why I just get corrupt data message – which file do we actually need in the update folder or are we having 2 named 500.pbp and 500(2).pbp?

    • sylv3rblade November 11, 2009 Reply

      No, you’re getting the wrong context of the instructions.
      You’re not going to touch the EBOOT.pbp in the UPDATE folder. The only file you’re going to rename is the EBOOT.pbp from the official 500.PBP zip (the one with 25.8 MB filesize).

    ah man… I just tried to do all of this and I followed the instructions exactly and then after the psp updated I got this blue screen it says this in many languages: “setting information is corrupted. Press the O button to repair and restore default settings.”

    Does anyone know what I should do. Should i press the O button?

      You’re not going to touch the EBOOT.pbp that’s already in the folder.

      The only file you need to rename is the EBOOT.pbp that’s INSIDE the zip file named

    • sylv3rblade December 27, 2009 Reply

      Tekken 6 requires that you have 5.50 GEN-B2 or 5.50 GEN-D3 installed. As for Dissidia, your copy is probably corrupted as it only requires 5.00 M33 so just redownload it again.

      If you’ve already installed 5.00 M33-6, then there’s no need to install the other patches.

      Also, unless your compy of the game is patched, Disgaea 2 only works on 5.50 GEN-D2.

    • sylv3rblade January 3, 2010 Reply

      What’s your current firmware version? The issue might be that you’re installing 5.00 M33 on a PSP with firmware below 3.71 M33. If you are then installation really takes a long time (and will most likely fail). The solution is to install an incremental update, jump to 4.01 M33 before 5.00 M33.

    Hey, I managed t upgrade my psp custom firware which was 3.71 M33 to 5.00 M33 with your help, and for that I’m very grateful. Even so because it seems I can still play my games without a UMD ^^ sweet stuff!!

    But now, when I decided to upgrade this patch, I did everything like you told me to, except that before putting the patch on the GAME folder, I decided to delete all of the files that already were on the GAMES folder. So, when I finally pasted the patch on an empty GAMES folder and tried to run it through the pc, something happened:

    – At first it wasn’t showing anything when I checked on my PSP on my memory card. So I started getting worried.

    – Then I decided to change the name of the patch to 500.PBP instead. It came up on my PSP when I checked it out, but as corrupted data.

    So now, I don’t know what to do. I managed to upgrade the psp to 5.00 M33 but I can’t upgrade it to 5.00 M33-6 meaning I can’t upgrade it to 5.50 GEN-D3 which is what I wanted in the first place…I mean, I’ve got Tekken 6 and I can’t play it, it sucks bad :/

    • sylv3rblade February 5, 2010 Reply

      If you’re already on 5.00 M33, you can readily upgrade to 5.50 GEN-D3 without installing 5.00 M33-6. 5.00 M33-6 only patches the bugs that 5.00 M33 contained.

    I’ve tried the other steps on various forums links, and keep ending up with “corrupt data” when I rename eboot to 500.pbp.

      How did you install 5.50 GEN-D3 in the first place? By using ChickHen? Either way, you’ll be needing a Pandora Battery to reinstall CFW.
      The reason you can’t install 5.00 M33 on your PSP is that it’s a lower version (5.00 is lower than 5.50) and you can’t downgrade a PSP without a pandora battery.

    Initially one of my friend had did that. But now i want to do by myself. So, I downloaded 5.50 GEN-D3 and try to reinstall in my PSP. But mistakenly I have installed “Flash Install OFW 5.50”. After that again i tried to run the 5.50 GEN-D3 then the message pop up saying that his game cannot be started. The data is corrupted.
    Right now i have got 5.50 Version System Software in my PSP. But I need to reinstall 5.50 GEN-D3. Is this possible without Pandora Battery? Please help me.

    Do I need to reinstall the Custom Firmware in my PSP in every format of my memory card??

    • sylv3rblade April 27, 2010 Reply

      Well you basically installed the official firmware so the only way to get past that is to downgrade using a Pandora battery. Using a Pandora Battery is the ONLY way to install CFW on a PSP once it exceeds 5.03 OFW :(. Also, no, you don’t need to reinstall your cfw when you’re just going to reformat your memory stick.

    guys, a little help please..? i’m getting error message everytime i run the 5.00 update under Game. it says:

    “This game cannot be started. The data is corrupted.”

    i downloaded everything (5.00 M33 & 500.PBP) and followed all those instructions above, but everytime i run the 5.00 updater, i’m getting the same error message..

    i got the installers from the links provided above so i’m pretty sure it’s not the files i downloaded.. i’ve done uninstalling and reinstalling everything for about 10x now, but to no avail..

    i have a Pandora PSP Slim 2006, current FW is 5.51 (before it was at 4.31 i think). i have no idea what happened.. please guys, i need your help..

      You have updated to the official firmware 5.51, you need a Pandora battery to downgrade and install CFW.

    Is this too long to unpack? I followed all the instructions above and started the update but it takes too long for it to unpack. what do you think is the problem?

    3.90M33 – 5.00 M33

      Shouldn’t take more than 5 minutes for the whole process. Looks like something went wrong.

    umm, I did end up downloading the official firmware 🙁 That’s what I had asked. So does this mean I have to make another magic memory stick and borrow my buddy’s Pandora battery in order to download the custom firmware?

    I want to go back to OFW. How would I go about doing this? I am currently on Gen-d.

    • OtisTheTownDrunk June 9, 2010 Reply

      when I try I get error reading 500.pbp at root. I have tried for different time, each with the eboot file from a different site, (thinking that I got a corrupt version), no luck.

    • sylv3rblade June 10, 2010 Reply

      You need a Pandora Battery to downgrade as your PSP won’t allow you to install an update that’s lower in version that your current firmware.

    Errrmm…. Why does it say that 500PBP is a incorrect file when i run the thing?

    • Darkelemrnt June 15, 2010 Reply

      do u have a pandora battery?

    • Anthony August 5, 2010 Reply

      Dude If you follow the directions nothing goes wrong. It says incorrect file maybe because you put the cfw and changed it to 500.pbp you have to change the FW to 500.pbp and leave the cfw as eboot.pbp

    hi. i have firmware 3.90 M33-3 on a psp fat can i upgrade to this fw directly???

    by doing this will i be able to play metal gear solid peace walker??

    thanx in advance 😀

    • sylv3rblade August 11, 2010 Reply

      Yes, you can upgrade to this firmware directly. To be able to play Peace Walker though, you need to install the prometheus module for this firmware.

    I had cfw 3.71 m33 installed but then I accidently updated to ofw 5.00 instead of cfw 5.00 m33.

    Do I still need a Pandora battery to install cfw 5.00 m33?

      yes but seeing as you have a hackable psp (based on your firmware), consider upgrading to 5.50 GEN-D3

    • sylv3rblade January 6, 2011 Reply

      You’re already running 5.00 M33-6? You can’t downgrade to 5.00 M33 without a pandora battery. Err why downgrade?

  321. Calvin January 6, 2011 Reply

    Never Mind 😛

  322. Calvin January 6, 2011 Reply

    Well the real reason is because i applied this patch so i could use the new psp camera, and i need 5.00 m33 for it to work

    Help…When I try to start the CFW it says that the data is corrupted. What should I do?

  331. Dubb July 13, 2012 Reply

    Thank you so much! I had 4.01 m33-2 installed because I dropped my psp and the UMD drive stopped working, I could only play certain games, and after a while my PSP sat neglected, collecting dust, because updating the fw seemed really complicated at the time. Your guide made it extremely easy, and now I only wish I had done it sooner. Tons of props for you 🙂
