Installing Pro CFW on a PSP 2000 (slim)

Translations for this article:

Installing a Custom Firmware on your PSP 2000 has never been so easy. In this page I’m describing the easiest possible way for you to install the most reliable Custom Firmware on your PSP: Pro CFW.

As a PSP 2000 owner, depending on your motherboard type, there’s a chance you can use other techniques such as the Pandora Battery to install a Custom Firmware. If you are interested in the “advanced” Pandora Battery method, please go check that guide, or the “Power users” section below. If, on the other hand, you want to follow the easy method (which for now I recommend), please keep reading.

Installing Pro CFW on your PSP2000 is simple, free, and is not much risky than installing a Firmware update on your device. It does not require any advanced hack technique or hardware modification. There’s basically 3 easy steps (you were expecting more? Sorry to disappoint):

1. Download the necessary files

2. Update your PSP To firmware 6.60

Skip this step if you already have Firmware 6.60 installed on your PSP.

In order to install Pro CFW on your PSP, you will need to first update your PSP to the 6.60 Sony firmware (which, at the time of this writing, is the latest firmware released by Sony), if that’s not already the case. There are versions of Pro CFW that will run on older firmwares, but updating to 6.60 will guarantee the best compatibility for your official games.

To install the 6.60 Firmware, just unzip the archive on your PSP’s memory stick, in the “PSP” folder (you should end up with an “UPDATE” folder in the PSP folder, if you do things correctly), then run the update from your PSP menu.

3. Install Pro CFW

The Pro CFW archive provides several subfolders in the “PSP/GAME” folder. Two of them are interesting for us: the FastRecovery and the PROUPDATE folders. Those two need to be extracted to the PSP/GAME folder on your memory stick.

Assuming you extracted the files correctly, you will see a few new applications in your PSP’s Game menu. The one you will want to run in order to install Pro CFW is “Pro Update”. Just run it.

That’s it. You can erase the “ProUpdate” folder from your PSP, but keep the “FastRecovery” one.


That’s it, I said 3 steps :) Welcome to the world of Custom Firmwares. There’s no additional step required to install the Pro CFW. However, every time you reboot your console, you will have to reactivate ProCFW, which is done by running the Fast Recovery tool from your PSP’s Game menu, and takes literally 5 seconds.

5. Power user

In this section you will find additional tricks/steps if you want to improve or customize your experience with a Custom Firmware on your PSP 2000

Some people think that it is a burden to reactivate the CFW every time they reboot their console. It is important to note that this is needed only if you reboot the console, not if you put it into sleep mode. Most people use the sleep mode 90% of the time without ever realizing it. Trust me, I’ve used several PSPs for years now, running the Fast Recovery tool is not a problem in your daily usage. That being said, since you’re running on a PSP 2000, you have a possibility to install the CFW permanently, assuming that your motherboard is hackable. This is done by running the tool CIPL FLasher from the Pro CFW (included in the archive). I won’t dig into the details for that (just run the tool will do the trick), just know that I personally think this is a feature you won’t need (and there is an additional risk of bricking your PSP) unless you use your PSP for dev purposes.

    This is probably a stupid question but, if I run CFW Pro and then hard reset my PSP, will it run the OFW as if the CFW had never been used? Or will it require a Fast Recovery to ever work again?

    • wololo says:

      If you hard reset your PSP, your PSP will run the OFW as if the CFW had never been used. However, some files used by the CFW are still on your console’s flash memory, this is why you don’t have to install the CFW every time you reboot the console, and instead you just have to run the Fast Recovery.
      Does it answer your question?

  2. carpish says:

    Is…is it really that easy? I just bought a refurbished 2003 PSP Slim (came without the box) so I have no idea if it’s the unhackable motherboard type. So, basically, you’re saying that it doesn’t matter for the partial CFW? I know there’s still bound to be some inherent risks.

    • wololo says:

      Yes, nowadays it’s that easy. the “partial” CFW has all the features of the permanent CFW, with much less risk. There *are* risks, but as far as I know, given the installation process, it is more risky to install an official sony update than it is to install pro CFW (unlike the Sony update, Pro CFW does not delete important system files while it installs).
      Note that with a PSP 2000 you may have a possibility to install a permanent CFW, but that’s personally something I decided to live without :)

      • carpish says:

        Great, thanks very much. I spent the last 3 or so days looking for information about CFW and much of it is out of date or rather complicated for newcomers. And yes, I won’t need permanent as I only need it to play English patched MHp3rd.

        Again – thanks alot.

  3. Shadow X says:

    Done my psp is hacked it was so easy to do it i got a slim by the way.

  4. sawdawsdsdasdasdsa says:

    it just says that it doesn’t support the program on mine.

  5. Deepak says:

    Hi i just wanted to ask a question.
    Will my ISOs which are patched to work for 5.00 m33-6 work for proB10

  6. LittleOne says:

    So what your saying is that I don’t need a pandora battery to put CFW on my psp?

  7. frank jaeger says:

    Ive been out of the cfw scene for quite a while. I have a psp 2004 ta88v3 and im on cfw 5.03 prometheus 3. should i upgrade to ofw 6.60 and pro cfw? and does this firmware have a noDRM setting in vhs?

    • wololo says:

      yes, 6.60 is the way to go nowadays in my opinion. You don’t have to care about prometheus anymore, it is directly integrated into the code of the 6.60 Pro CFW.

  8. frank jaeger says:

    shoot! i didnt know there was info on the pro cfw link. sorry.

  9. Mikatchu says:

    I’m already having thouble doing the very first step.
    I put the FW in the PSP folder, and disconnected it from the PC. Went to ‘System Update’ on the PSP, ‘Storage medium’, and it says there aren’t any usable updatedata found..

    Did I do something wrong here?
    I have a PSP 2004, OFW 6.37
    and zero experience with CFW.

    • wololo says:

      your proble, is not with CFW here, but with the OFW, it seems. Make sure you have the OFW file in PSP/GAME/UPDATE. You should have a file named EBOOT.PBP in PSP/GAME/UPDATE/EBOOT.PBP on your memory stick. Then go to the “game” section of your PSP, and the update icon should appear among your games.

  10. Mikatchu says:

    Worked :)

    Thanks alot.

  11. cheapshot says:

    help please. I’m having trouble with 6.35 PRO Hen. The screen freezes when I’m choosing the game I’m going to load at the Prometheus ISO loader screen. Every I run Sukkiri, it says, “kernel memory dumped into ms0:/kmem.bin”. It doesn’t say this before I copied an Assassins Creed iso into it. Then everything went downhill.

    please help.

  12. pspnub says:

    will this work on a ta-088v3 motherboard? can i upgrade it to ofw 6.60 and then install latest pro cfw (i think pro bd10)?

  13. liam295 says:

    i’m new at this, but it worked no problem ( i did have to use diffrennt usb cable though). had to create an iso folder though

  14. abd says:

    was using m33-6 was last 3-4 years. just now updated to this version. it was a breeze. thanks for this wonderful sw.

    installing cfw is so easy………..

  15. P69 says:

    Thank You!
    Its wWorkin’ fine on my slim!
    I’ve been searching for this at about a year and now im find it thank you again:)

  16. jacq says:


    I just rekindled my interest in my dusty psp, hope you’ll render some help to this noob here.

    I just checked my firmware, it says 3.71 M33-2, the last time I touched it was in 2008. Can I follow this guide to install the Pro CFW here?

    Also, whats the use of this Pro CFW? Does it mean that after following through this guide, I will be able to run recent games downloaded online on my psp?

    Much thanks!

    • wololo says:

      Hi jacq, yes, this guide should work for your 3.71 psp. The idea is to go first “back” to official Firmware 6.60, and then install Pro CFW. One problem you might run into is that some custom firmwares, in some conditions, prevent you from installing official firmware. If that happens to you the best I can tell you is to ask for help on our forums, there are solutions if that happens, but it’s too long to describe here.

      Pro CFW is basically the continuity of M33: the creators of Pro CFW reversed the M33 firmware completely, and updated it to work with more recent firmwares.
      As far as being able to play online.. if you mean through the PSN, to be honest I am not sure, as I myself never play online. For that you’d have better luck staying on 6.60 Official Firmware.

      • jacq says:

        For the online part…

        I meant, recently released games. For example, I downloaded GTA Chinatown Wars but the games wouldn’t start on my psp. Could it be my psp firmware is too old, hence incompatible. By installing Pro CFW, it might be able to solve the prob?

        Thanks in advance!

  17. rhaj109 says:

    If i did your guide will my PSP have a chance to get bricked?
    I also downloaded many games/ISOs from the internet, If i do the things in your guide like going 6.60 then to PRO CFW, can I just copy+paste the games in my psp then it will run the games automatically? Plz i need your help

    • wololo says:

      The risk of brick is lower than if you installed an official firmware.
      Don’t ask questions about warez here, I won’t answer.

      • rhaj109 says:

        ok thank you. BTW, if i did the CIPL flasher..does it mean that i don’t need to use the Fast Recovery tool anymore?

        tnx anyway

  18. gurps says:

    Thank you very much for this wonderfull and simplified page.
    i succesfully hacked my psp 2004 ..thanks again for making this page.

  19. John says:

    Can I delete all the files if I was able to run the permanent install?

  20. John says:

    To be more detailed, I am talking about the sdk and seplugins folders on the root. Also the cipl updater, fast recovery, and proupdater folders under game.

    • toBsucht says:

      fro example if you delete plugins floder you cann´t use them as long as they aren´t at flash (brick risk). Just restart you psp without the files you don´t like and you know

  21. N6v7d8 says:

    I tried this on my 5.03 TA88V3 and it’s working :)
    Thank you so much…

    I have a question and request….

    Is there a way for 5.00 M33-6 to make it 6.60 PRO B10?

    can anyone please give me a step by step guide?

    Thank you very much :)

  24. lav says:

    hi im having trouble updating my psp to 6.60 i followed the guid exactly and i cant update it any reason y?? plez help

    • wololo says:

      What type of error do you get? There are two typical reasons for not being able to update to 6.60:
      1) You were using a CFW which is preventing you from updating (I think the Gen CFW has issues like that)
      2) You are trying to update a psp go with a firmware for UMD models, or vice versa

  25. Sind says:

    Does PopsLoader work on this?

  26. Agentman says:

    Well, my PSP 2001 board is a TA-88V3 and updating to OFW 6.60 was fine, but proceding to CFW PRO B10 stops after press “X” to reboot and my PSP crashs and power off. Fortunately it works normally after crash, but in OFW 6.60.

    Please, can you help me? Did I do anything wrong?

  27. UltimagaWeapon says:

    Hello, I’ve been having problems upgrading my CFW.

    PSP2000 model. I currently have 5.50 GEN-D3, I went to the PRO site to upgrade, but it mentions something about upgrading to OFW first (6.20~6.60) before trying to install PRO.

    I don’t really know how to approach this. Since I currently have a really old CFW, there’s a chance I might brick my PSP? Is there any safe way to install OFW and then PRO if I already have old CFW?

    • toBsucht says:

      Disable all plugin
      writte a 5.xx version text to flash if it´s a higher version as 6.39 to use a ofw update. Done!
      Now it should be possible to follow Wololos guide without brick risk.
      [I´m not 100% sure if you may can use a signed 5.50 gen.]
      Pro hen/cfw is the only one with online server.

  28. Kabugi says:

    Heya heya. I’ve been out of the modding scene a longggggggggggggggg time and have become noob all over again.

    The last CFW I installed on my psp a couple years ago was the 5.00 m33-6 update to the 3.71 m33-4.

    What’s the best way to update without bricking? Do I need a pandora battery to reset the firmware to 1.5 if switching from m33 to Pro?

    Thank you very much!

  29. The guy on the corner says:

    Ok i haven’t even looked at my psp for a year and I have 6.39 ME-9.5 exh and I have no idea how to update it

    • falanx says:

      You have to update first to 6.60 OFW, put the downloaded files from 6.60 PRO CFW to your game folder, launch Pro Update, if your psp is fully hackable run the Cipl flasher. Otherwise just run the pro update and there you go, you are on Pro LCFW.

  30. ikwest says:

    Hi. i am definitely a total noob, never done cfw before and have problems following the simple steps above. can’t even get past step 2 – install ofw 6.60. i have a second hand psp 2001, running on cfw 4.01 M33, it was modded by the previous owner. I had followed step 2, and copied the EBOOT.PBP file to the memory stick at PSP/UPDATE. But when i go to the PSP menu and the Game selection, i just see the ISOs i have, but see no PSP Updater. Am i missing something? Tried rebooting the psp, but still on 4.01 M33 and still no updater. Please help?

    • ikwest says:

      i figured it out – EBOOT.PBP should go to /PSP/GAME/UPDATE instead of /PSP/UPDATE. the steps above assumed i knew that, but i didn’t, as i am total noob. have updated to 6.60 PRO-C. Thanks vm for the guide!

  31. Sultan says:

    I followed the guide, I have a PSP 2004, it told me i was already on 6.60 so no need to upgrade, i went to step 2, and then in the game menu, the update appeared but along with that there were 2 other options saying “corupted data”

    what did i do wrong ?

  32. asdfa says:

    I installed the update but cw cheat wont work. I’ve looked at the recovery menu and it does not show cw cheat in the plugins. I don’t know what I am doing wrong.

  33. chip says:

    i put both pro update and fast recovery on psp/game, like the instructions said, but, unlike the instructions said, the game menu on my psp had no additional applications. Did i do something wrong?

  34. babymoses says:

    Greetings, I have a 2001 model on 5.50 GEN-D3. I say this as I don’t know if that is one of the firmwares that won’t allow installation of OFW. I guess I donb’t have the bitchy motherboard.

    I just want to make sure all is well before I attempt to update the firmware (I am a sissy). If plugins must be disabled, please tell me how to do so.

    Thanks! You’re awesome!

  38. format says:

    cheers for guide ! quick question – can i use PSN/online games/etc. with the OFFICIAL firmware ? this method seems to leave CFW in flash memory, i’d be upgrading from ancient gen-C that gives me trouble with a number of games and it’d be handy to hard reboot so i could use psn/ps3 features if i wanted to. ta for any answers !

  39. salad says:

    The letter or ‘letters’ in my case say ‘NP’ on my original psp box it is a psp 2000, is it hackable? :)

  40. peacewalker says:

    Hi,Wololo. I have installed 6.60 pro-c (CIPL installed)on my psp 2000 (non v3 motherboard). I got few questions listed below:

    1- In my pro-c, I turn off my psp and turn it on with pressed the home button key then it will booted to 6.60 ofw. Is this consider normal? (Or due to file left by 6.60 ME 1.8 that I previously install?)

    2- Everytime, I on my psp the UMD slot will running automatically even with no dics inside and quit game screen occur during gameplay… This doens’t happen after I upgrade to 6.60 firmware.Do you have any solution?

  41. JOSH says:

    Hi wololo,

    This is seems a very reliable article so I might as well ask here… I have been out in the loop on the latest CFW and I was stuck on my old 5.00 M33-6 (with Prometheus patch). I’ve been thinking if I should finally change my CFW. But I wanna know some things before doing it…

    1. What is the latest (and stable) Pro CFW so far?
    2. Is it safe to update it coming from 5.00 M33-6?
    3. Will my save data’s, plugins or even PSX EBOOT can run on the latest CFW?

    Hope you could answer it. Thank you very much!

    • wololo says:

      1. Pro C fix4 is the latest version. Lots of people stick to Pro B
      2. Yes
      3. Some plugins might stop working. Not sure about PSX Eboots. Some save data might stop working, but this is not a problem with the CFW, it is a problem with Sony’s firmwares breaking *some* save files with the update (making them incompatible). This is rare AFAIK

  42. Shaeno says:

    Hi! I got PSP 2000 and I got it customized. It was working fine until it frozed and stopped working. Everytime I reset it and start Fast Recovery my PSP is frozen. My psp’s version is 6.60 and I’m using Fast recovery PRO 6.60.

    How can I fix this? Please help.

  43. carlo says:

    i just wonder why my 5.50 prome-4 can not update to 6.60….

    I have a PSP2006 with 5.00 M33-6 (dont know if its Prometheus patch or not)but I had this long before. I have been doubting of changing it to latest CFW. If u could clarify some of my questions it would be much appreciated.

    1. Upgrading my 5.00 to 6.60 is the procedure and file above applies or would need a pre requirement before it can be upgraded?
    2. Will this upgrade to Pro can i still use my old games like MHF Unite and its save files??? it my fave game… and i want to simply use it for portable 3rd??
    3. Can u revert the changes or upgrade like from Pro CFW to 5.00 again if in case i find it not working on my old games???

  46. ha7ak3 says:

    I updated My PSP 2000 from 6.31 Hen to to System Firmware 6.60 and my Everybody Sukkiri along with Prometheus loader stopped working.

    Guess what, the Pro- Recovery and Pro Update helped me get my PSP to look like a new device to play now All my ISO can be played without the ISO loader..

    Thanks to all you Geeks.

    Luv & Respect,

  49. Ilitsa says:

    I’m currently using 5.50 Prome-4 cfw, and want to update to 6.60 pro c. I used a pandora battery at first to get my original cfw (it was some m33 version, I forget which) but I no longer have the pandora battery. If I update to OFW, will I be sc***? Trying to install from my 5.50 to the 6.60 pro c says “Sorry. This program doesn’t support your FW(0x05050010).” Is it ok for me to update to OFW? Will I still be able to put the CFW on? Even if it’s where I have to re-do the CFW any time it powers off, thats fine with me. I just don’t want to put the OFW back on and then be sc*** and unable to use my psp since I got rid of my UMDs

  50. kner says:

    all done withthe installations…
    it may seem like a newbie question but can i play iso games now on my psp?
    because i downloaded a game created a folder in games named “ISO” copied the game there and in my psp it recognizes it as corrupted data.
    any help?

    • DatSikBoyz says:

      Ok create a new file name ISO (exactly like that), and you can put your games in there.
      Next go to the home screen on your PSP
      Press Select
      Choose UMD ISO MODE => SONY NP9660
      Mine works like a BAWS

      • toBsucht says:

        umd iso mode = iso driver Sony NP is the orginal which isn´t as fast as m33 (from old gen)or the new pro driver which should be the best^
        “Ok create a new file name ISO”
        btw i got to ISO floder 1 at the root (close to PSP floder)
        and 2nd inside PSP/GAME to show isos in xmb. Not sure if 2 floders are still needed.

        • HT says:

          Just a note guys, the ISO folder goes in the root folder, not in PSP. So you should be able to see both ISO and PSP from the main folder.

    • toBsucht says:

      Maybe you use a faked version text, than change it to 5.50. Yes, disable plugins and reboot into ofw than you can go one with Wololos tut. Search such questions at www. …´s answered often at this blog^

    Just performed this procedure on my 2004. No problems in running the procedure. However now i have problems with my joystick. It seems to continously go up (eg when playing games or the internet browser). I have tried a spare stick and contact rubber with no result.

    Can this be due to the ofw upgrade and cfw installation?
    Is there a way to go back to an older ofw to check?
    Any ideas?


    • Div says:

      Try using joysens, you can change the sensitivity of the analog stick. The stick sensor is probably damaged.

      • cb says:

        Hi Div,
        I have installed joysense and checked the stick.
        The y axis remains on -128 continously, no matter if I move the joystick up or down.

        Could it be that something on the motherboard is not ok?


    • DJ McMahon says:

      I had the same problem but I doubt that it’s the CFW. Take apart your PSP and remove your joystick. Then unscrew the mount that it is on and take a Q-tip and gently clean the golden plates and also where the black square thing that the joystick sits on, try to swab the inside aswell. and put everything back together and you’re done. ^.^

  55. Div says:

    I’d like to play a backup of a Japanese game which I bought in Japan on 5.00 m33, instead of updating to the PRO or GEN systems. I’ve tried patching the ISO that I made of the disc using ISO tool, but the game always crashes ( it doesn’t even boot me back into the XMB ). It’s the same whether I patch it or not. What could be the problem? This seems to be the case for all the recent 6.60 games released in Japan. ( I have a few )

    My PSP is a fully hackable 2000 running 5.00 m33-6 and I use the prometheus patch ( installed using RedSquirrel’s prometheus installer, and I installed all to flash ). I have the original UMD and the update included on the disc is for 6.60. Any pointers? Thanks in advance!

      Yes, this should work. Be sure to install 6.60 OFW first. The risk of brick is minimal, it is basically the same risk as when you install an official firmware from Sony. So basically, no risk unless you unplug the device while the CFW is installing

  65. mattlikestoplay says:

    my cfw is 5.50 prome-4 as well, but when i update it says that my version is 9.90 and does not need to update T_T what do i do?

  66. kemala says:

    Hi, I can’t extract then Firmware 6.60 file :(

  67. Rafael says:

    Hello, my PSP is a 2001 model on 5.50 GEN-D3.

    First I got the 9.90 problem, then i changed the version in the txt file on the flash… now when i try to run the OFW 6.60 it’s says “This Game Cannot be Started”.

    Tryed to download it again, extracted it again on the right folder, but it keeps giving me the same messege… :(

    I don’t know what to do anymore. Anyone got this problem?


    • toBsucht says:

      You can get the update (ofw)from Sony with the use of wifi..
      Then you get the correct update file in the correct floder
      as long as Sony release no update.

  68. Kevin says:

    Hello, I have a PSP Slim 2000, I have it on OFW 6.60, I have downloaded the PRO B10 CFW, and I extracted the appropriate files to the “GAME” folder. When I run the update, my screen is black (or blank what have you) it sits for about 15-30 seconds, and then just turns off. The option to install the CFW never appears. Any help you can provide would be amazing.

    • Kevin says:

      My Apologies, it’s a 2001 Model, I think that still classifies, but I wanted to be as technical as possible. I ran the Module Checker, and the motherboard is a 02G, the FW Build is 5445,0,3,1,0

  69. hanna sheree says:

    the hack worked fine, but when i go to system settings to check, my psp hangs and it would turn off.. why is it like that??

  70. hanna sheree says:

  72. Cyril says:

    I’ve tried following the steps as closely as I can and I manage to upgrade to ver 6.60 but I keep getting a bunch of corrupt data in my PSP Games menu. Please help

  78. Domtorreto says:

    I have done everything as per the procedure but when i run the cipl flasher it says that this is not supported by your model. Please suggest me some help soon.

  79. rak says:

    useless. didn’t help whatsoever. very nondescriptive and far too vague to help at all.

    • wololo says:

      Lol, it’s because the process is so simple a 5 year old kid could do it. No need for useless descriptions when the process is that simple. Of course if you don’t know how to decompress a file or plug your psp to your computer, then what you are looking for is “computers for dummies” instead of this guide :)

  80. sahd says:

    Ok i install the cfw pro on my 6.60 ver but some game dosn’t start became black screen the the psp turn off ,, can any one help …

  86. L jones says:

    Quick question: I have installed cfw 6.60 (not the permanent one) on my psP 2003 and want to transfer everything to a bigger memory stick. Do I have to re-hack it so to speak or do I just need the quick recovery from the existing memory stick, if that makes sense.

    Any help would be appreciated 😉

  87. mojo says:

    hey i have cfw promethues 4 and i wanna update it to 6.60 cfw , and that pro cfw is okay but there is one thing that annoys me which is that i have to activate it every time i open my psp , it seems that its the same as those simi cfw’s on the unhackable psp’s and my psp is fully hackable so is there any other 6.60 cfw that doesn’t need me to activate it every time i open my psp? please say yes :( and thnx in advance

    • mojo says:

      alright sorry 😀 i didn’t read the whole thing okay i got it, i installed it permenantly and all done thanx great job

  88. Adonai says:

    I don’t get this, i downloaded the CW thing and i get 2 maps PSP and seplugins and this guide only sais to put 2 of the three folders in the PSP map to my psp>game directory, what do i do with the other stuff?

  89. Adonai says:

    Oops, i now see in only downloaded the update, there are actually 5 main maps in the download there’s PROUDUPDATE, fastrecovery, sdk, CIPL_Flasher and seplugins.. where do i leave all this besides PROUDUPDATE and fastrecovery? And how exactly do i ”run” the thing in the proudupdate folder?

  90. neilbano says:

    hello, I followed everything as the step goes, and made the program work. However, there was this accident that I dropped my psp and as soon as I tried playing it I noticed that the hack doesn’t work anymore. neither does the fast recovery. everytime I start the FastRecov my PSP shuts down(turns off). What do I do? It only did this after I dropped my PSP. Prior to that it works perfectly fine.

  91. Alfonso Villareal says:

    I tried following your guide but I’m having trouble updating my PSP 2000 to 6.60. Every time I try to extract the OFW winRAR says “! C:\Users\Hp\Downloads\ The archive is either in unknown format or damaged”. I don’t know how to proceed. Can anyone please help me out?

  92. Nick says:

    Hi, does this CFW requires a genuine memory stick pro to use? I haven’t touch my PSP in years and I remember that 5.00m33 requires a genuine memory stick pro to activate.

  93. Alfonso Villareal says:

    Hi, I successfully updated my PSP 2000 to 6.60 using Sony’s OFW, I also managed to install CFW on it. Problem is, now my PSP gets stuck with the wallpaper and a circle(the one that indicates that it is loading). I shut it off and turn it on again and it works sometimes, but sometimes it doesn’t. I don’t think I’ve managed to brick my PSP because it still does work. Also, when it does work there isn’t any ISOs visible anymore, even if I know that they worked before. Is there a way to fix this, if so how? Thanks.

    • toBsucht says:

      Do you use plugins (do not enable to much of them at the same time) maybe set cpu speed higher. Also i believe it can be a bad connectors of your MS sometimes cleaning works.

  94. Ahabit says:

    Hi, I’ve updated my psp to 6.60 and doenload the CFW, but when I go to the game option in my psp, it keeps saying “corrupted data.” I’ve downloaded the software and have extracted the files to that part of the folder, but i keep getting this message…

  95. Mimi says:

    I put it in the game folder on my memory stick, but the update didn`t show up

  96. Kreed says:

    Okay. I have 5.00 m33-4 on my psp. Is there any way to update to 6.60 without the sony update cause I don’t have the pandora battery or the magic stick. Don’t even know if you need that it’s been a while for me. Someone please help me

  100. Dash says:

    Received a console that had 5.50 prome 4. Followed instructions and have updated to 6.60. When I go to load Pro C2 the console closes and then quickly display CFW install options with ‘exiting’ at the end. There is no way I can press a button in time to install. Have not had this issue on any other console. MB TA 085

    Can I get around this? Have tried different memory cards with no success.

    • alevineman says:

      Install 6.60 ME-1.8 while in Test M33. That should fix your problem. It flashes a cIPL, which appears to be your problem. If not, use your pandora and MMS.

  102. Bryan says:

    how many mb’s does this 6.60 update have?

  103. nfjd says:

  106. Sudo_Made says:

    I have a PSP Slim 2002 zy (Yellow Simpson’s Release) with Dark Alex’s M33-6 CFW and followed these instructions starting with upgrading to Sony OFW 6.60 and then ran the Pro CFW 6.60-C fix 3 update and everything worked great. A lot easier than how it used to be to get CFW running, lol.
    Thanks Uploader!

  109. Polymar says:

    After upgrading to 6.60 ofw and installing pro-c2, my iso won’t boot. They got stuck with a black screen. All of them worked with 5.00 m33!

  110. marriedman says:

    I found my PSP2001 the other day and thought I would update it. I had 5.50 GEN-D3 installed. I downloaded the official firmware per the instructions and went about installing it. I got the issue that I am currently running 9.90 blah blah blah…. so I mount flash0 and change the version.txt to 5.50.

    Now I can apply the update. As soon as I did, I got the red screen of death. ” A serious error has occurred…” I tried installing Hellcat’s Recovery and the got me nowhere. And the newest thing is that my memory card is now wiped clean. I still have GEN Recovery, but now I have no Helcat Recovery. If I create the PSP folder, then GAME, then RECOVERY and add the Hellcat recovery to it, it won’t load.

    Is my PSP completely bricked now?

  111. Vilcker says:

    on my psp 2000 / 5:50 Prome -4 is giving this error [ Sorry. This program doesnt’t support yout FW ( 0x05050010 ) . if someone can help me thank you

  112. Cyntiii says:

    What if update 6.61 is availble.. does it stil work then?? or should i stay at 6.60 to make sure itwill work?

    My psp has version 3.60

  114. Ulip says:

  115. toBsucht says:

    you don´t have 6.60 ofw installed.

  116. hanna sheree says:

    got the same problem. i tried to install 6.60 but it says that i have 9.90 firmware and does not need an update but i only have 5.50 prome-4 fw..

  117. bob says:

    hahhahahaha, welcome to the past hanna. I guess your only option is to wait until sony itself releases the official 9.90 FW so that it could get cracked and turned into cfw

  118. EzpadaZ says:

    You have “9.90” because past in the days i don’t remember if it was for playing online or bypassing updates…. or both… who knows. Yet you have a version.txt somewhere i your psp. 5.50? For gods sake update now….

  119. Dash says:

    Press select on your psp then change usb device to flash 0.

    Connect your psp on your computer go to vsh folder.

    Go to etc folder and open version txt.

    Change release from 9.90 to 5.50 and save.

    Console is ready to be updated to 6.60 then Pro C2 as per normal.
