Can my PSP have custom firmware installed?

I’ve been receiving tons of questions on how to check if their PSP can have custom firmware installed.  Here’s a complete and concise guide to get you going.  Make sure to read through the guide fully since it will answer all your psp motherboard related questions. First of, you need to understand that there are three types of PSPs:

  1. 1000 Series (Also known as PSP Phat/Fat)
  2. 2000 Series (Also known as PSP Slim or Lite & Slim)
  3. 3000 Series (Also known as PSP Brite)

So why install Custom Firmware on a PSP?

People install Custom Firmware so they can run Homebrew, programs developed by people that don’t have a contract with Sony. A PSP with Custom Firmware could also back up your games from the UMD to your computer; it also allows you to play those backups from your Memory Stick (MS). You could also do some serious customizations to your theme. Basically, you free your PSP from the hands of Sony.

Can I install Custom Firmware?

Before anything, you should know that there three ways to classify Sony’s PSP.  Hardware, motherboard and Hackability.


To date, these are the hardware models of the PSP

  • PSP 1000 or the PSP Phat
  • PSP 2000 or the PSP Slim
  • PSP 3000 or the PSP Brite
  • And last but not the least, the PSP Go


Each hardware model of the PSP change motherboards over time.  However, this classification is only important for the PSP-2000 Slims.  Why?  I’ll tell you that in a bit.  The PSP Slim has 6 motherboard versions but we’ll focus on what’s important so I’ve split them into just 3.

  • 1st generation PSP Slims: pre-TA-085XX motherboards
  • 2nd generation PSP Slims:  TA-088v3 motherboards
  • 3rd generation PSP Slims: TA-090v1 motherboards


The hackability of your PSP [in simple terms, can you put CFW on your PSP] depends on several factors.  I’ve made a list so you can easily classify things:

  • PSP-1000s are completely hackable.
  • 1st and 3rd generation PSP-2000s are completely hackable.
  • 2nd generation PSP-2000s and PSP-3000s are partially hackable

What does completely hackable and partially hackable mean?

A completely hackable PSP means that you can have custom firmware PERMANENTLY installed on it.  This means that the custom firmware stay on your PSP until you decide to remove it.

A partially hackable PSP means that it’s custom firmware is only temporarily loaded via a special exploit called the Chickhen hack.  If you shut down your system or had it turned off, you need to load the custom firmware again.

What will prevent me from hacking my PSP?

There’s several factors that will stop you from installing custom firmware.  Here’s a run down:

  • A 2nd generation PSP-2000 with firmware ABOVE 5.03
  • A PSP-3000 with firmware ABOVE 5.03

Why version 5.03?  Because 5.03 is the only firmware version that supports the Chickhen hack.  Firmware versions succeeding it (5.50, 5.51 and 6.00) have this exploit patched.

Is my PSP Hackable?

This is the simplest method out there.  You can check things manually but this is the recommended method:


Install chickHen R2Before you proceed, you need to install and successfully run the chickHen hack. Read the guide and come back here to finish the installation.


  • Connect your PSP to the computer in USB Mode when you have loaded ChickHEN R2.
  • Extract the file to your computer
  • Copy the PSPident folder to your X:GAME/GAME3XX folder
  • Disconnect your PSP
  • Run PSPident
  • If you did it right, you should have this screen pop out

PSP Ident

With that information, you can compare it to the table below to see if your PSP is hackable.

Hit for the Full version

Manually Checking your PSPs hackability

If you want to do things manually.  Follow this guide:

  1. What is the Firmware the PSP came with?

  2. The original firmware that came with the PSP right out of the box is an indication of its Motherboard, & here’s the list: If you’ve bought a PSP with Official Firmware higher than 4.01, chances are it doesn’t support Custom Firmware, any attempt to install it will be met with a Game could not be started error. Note: If you updated the PSP or the PSP you’ve bought has been upgraded before you got your hands on it then you need to find out what was the first firmware installed on it as the list above only applies to said version.

  3. What is the PSP’s Serial Number?

  4. The Serial Number is found on a label where the battery is supposed to go. Refer to the picture below for a better illustration: PSP Serial Note that this applies to Piano Piano Black PSPs (for now). If the serial starts with HU2, then the PSP most likely has a TA-088v3 Motherboard. Any other serial (Say starting with HC or HB or HJ) can have CFW installed.

  5. What’s is the PSP’s Identification Letter

  6. It’s the letter on a label on the box that indicates the version of the unit. A picture is shown below: Note that this label is only present on the normal PSP box and not those large “Limited Edition” ones. PSP Serial Anyways, See the G there?

    PSP-2000 CW 100v G

    That G is the letter in question. Here’s a list of all the letters that the 2000 series ship with:

    (No Letter) = 3.60
    A = 3.71
    B = Doesn’t exist
    C = 3.72
    D = Doesn’t exist
    E = 3.80
    F = 3.90
    G = 3.95 (TA-088v1) / 4.01 (TA-088v2) / 4.01 (TA-088v3)
    If the letter is absent or is from A to F, then you can install Custom Firmware. If it’s a G then you can’t.

  7. What’s the Box’s Serial Number?

  8. If your box doesn’t have a label with a letter in it, like the G in the third method, then it should have a label with another serial that’s not related to the PSP unit. PSP Serial Note that American 2000 series (2001 PSPs) & Japanese PSPs (Both 1000 series & 2000 series) Don’t have those date codes on them, just like the 2001 Piano Black PSP pictured above. The 2000 Series Date Codes go as follows:
    7C: Supported by cfw
    7D: Supported by cfw
    7(Any later Letter): Supported by cfw
    8A: Supported by cfw
    8B: Supported by cfw
    8C: very high chance it's not supported by cfw
    8D: Not supported by cfw

How can I install custom firmware on my PSP?

If you have a completely hackable PSP (please read the guide again if you don’t know what a completely hackable PSP is) then you just need to follow the basic installation guide:

If you do have a PSP-3000s and PSP-2000 with TA-088v3 or any PSP above 5.50 OFW then you’re in luck.  You can still enjoy games and homebrew on your PSP by installing any of the following Hen + ISO loader combo:

These are compatible with ALL PSP models so you can install 5.03 GEN-C, 6.20 TN-E or 6.35 PRO-B5 regardless of your PSP unit.  At the moment, all available firmwares for the PSP are hackable except 6.37 and 6.38 so please don’t update to that.  Read this for further information about 6.37 OFW, 6.38.

Now, if you’re still not sure how to proceed, ask a friend who’s familiar with Custom Firmwares to check for you. If you have a suggestion or a question, just post a comment.

    ok, so I got a limited edition Madden 09 4.01 OFW, so your saying I should just give up on not having a CFW in order to play psx games? please reply, your answers are greatly appreciated ^^,

    My PSP is a Brite one. However, the serial code found at the battery storage starts with HU. Is the CFW possibly installed in it? Another thing, is that true if the UMD game Idol Master, if you update the version of it (5.05) is it possible for hacking?

  4. atmaxplorer sylv3rblade April 20, 2009 Reply

    The PSP brite is still not supported by CFW. It’s on the guide.

    Hi Sylv3rblade,
    first, thank you very much for this blog post!

    Second, I’m a bit confused. Few days ago I bought a PSP Slim and after reading your post I’m still not sure if I can use CFW.

    It came with 3.95 firmware (yay!),
    serial number starts with “HC” (yay!),
    PSP’s identification letter is “G” (boo!).

    So I have 2 yes and one no CFW. Can I install a CFW? o_O

    Thanks in advance!

  7. jeestyle Nemanja Nenadic April 26, 2009 Reply

    I also forgot to mention that I’m from Europe so there might be some difference in serial numbers etc. And the model is “PSP-2004 PB”

    good guide mate. made me confirm some things about purchasing a psp. Also, if you already have a psp and want to be completely clear on what motherboard you have I suggest using PSPident while in ChickHenR2 mode. works like a charm, unharmable (5.03 only)

      I think it’s the image that’s causing the problem. I’ll try to update… but to clear things up. Yes, PSPs with TA-088v3 motherboards can now have custom firmware.

      This part:

      Update: PSP-3000s and TA-088v3 – equipped PSP-2000s can now install custom firmware. How? Via the chickHEN hack

    I have a PSP Slim, and the serial behind the battery starts with HU0.

    The box does not have an identification letter or a date code, but it does have a serial number that starts with AB00.

    I am not sure if this a TA-088v3. If I use the chickHEN hack for TA-088v3, and the motherboard is NOT a TA-088v3, will it harm my PSP?

      No it won’t. It’s safe for you to use chickHen and the custom firmwares that run on it.

    @sergz, I dont know why you updated from the official site, It seems that you had custom firmware already, The official firmware doesnt allow you to play modded games unfortunately, Hard luck dude, But if I get a positive answer to my question then Its just a matter of you getting a pandora bat and a magic stick, here. check this vid out for a better understanding of how it works.

    My kids have 2 PSP SLim 2000 and we already hacked it with CFWenabler 3.60 and Chickhen.
    One of the PSP recently produce shaky display and response really slow. I also noticed when I connect to PC via USB it cannot read the whole content of the memory stick. Only certain part of it. I guess the memory stick is corrupt. When I do Master Reset the unit behave normally without shaking and slow response.
    Can I format the memory stick and copy from my other PSP memory stick to the newly format Mstick? Will it works?

    Firstly thanks for the article 🙂

    From reading the guide it sounds like mine cannot have CFW installed?

    Mines a 2003 and referring to the guide it has the following:

    1. 4.01 Firmware
    2. Serial starts with HB
    3. Has a G on box

    I’d be tempted to put CFW if it is compatible as it would be nice to play my old PSX games 🙂 But I don’t want to brick my shiny new, old model, PSP.

    Hi there,
    what about a psp2006, with ofw 4.01, letter “G” and the serial starts with HE2.
    In the tut it says G” no cfw, but it also say: G can be 4.01 (TA-088v2) or 4.01 (TA-088v3)
    If it is a “G” 4.01 (TA-088v2) is it hackable?
    If not, ignore the rest of the text.

    To find out what board is inside, install 5.03, Hen and run pspident. If it is a TA-088v2 is it possible to downgrade to older ofw/cfw?

    Hey sylv3rblade,
    Great info, the best I’ve found so far after 2 days of searching.
    I’m stuck though. I have a 2001 OFW 5.51. I want to run PSP Ident but I can’t install chickhenR2 due to my OFW. What to do?
    It is a “daxter promo” and the serial is HU315XXXX. Can you tell me if my psp is hackable?

    • atmaxplorer sylv3rblade October 15, 2009 Reply

      If it’s from the Daxter PSP Bundle Yes it’s hackable.

        Thank you sylv3rblade. I don’t know anyone with a pandora battery (which I need to make my own), so I suppose my next step is to order a pandora battery from the internet. Might as well order a preloaded memory stick while I’m at it. Your link for ordering is no longer valid. Any suggestions on which retailer is valid? Thanks again!

        • whitmanronaldlee Ron Whitman October 19, 2009

          Sorry about the false information on my last post. I do NOT need a pandora battery to make a pandora battery, only a modded psp. I’ve actually found a friend with a modded psp and I’m back on my mission! I’ll let you know how it works out!

    Mr. Sylv3rblade, thanks to you I am currently running cfw 5.00 M33-4! Woo-Hoo! Saying that, I did have a few issues. First, trying to create a slim pandora battery on my friends modded phat psp. It was easy enough, just don’t let go of the battery during the process! Secondly, I was trying to be slick and put “pspgrader” on one memory stick and “pan3xx” on another. It worked well enough, but when I needed to convert my battery back from pandora, I had to locate and copy the “battery serial on file” from one memory stick to the other. It was also easy enough but I would not recommend it. My next project is to try and figure out UMDGEN. You wouldn’t happen to have written a post on that as well? Thanks again for your awesome tutorial!

    • whitmanronaldlee Ron Whitman October 21, 2009 Reply

      sylv3rblade, I updated my CFW from 5.00 M33-4 to 5.00 M33-6 to 5.50 GEN-A(Full) to 5.50 GEN-B(Full) to 5.50 GEN-B2(Full), but my system information only states 5.50 GEN-B(Full), not the B2. Is that right? By the way, I got that whole ISO, CSO and UMDGEN thing figured out. This is awesome, I should have modded a long time ago! Thanks!

      • atmaxplorer sylv3rblade October 21, 2009 Reply

        Don’t worry, that’s normal. Installing GEN-B2 will still display 5.50 GEN-B(full).
        Congrats on converting 😀

        • whitmanronaldlee Ron Whitman October 21, 2009

          Thanks for the “congrats”, definately could not have done it without your help. I also took your advice and did not flash up to CFW 5.50 GEN-C.
          When I used to run OFW, I would update the OFW through my home wireless router. Is it possible to update my CFW this way with CFW installed or do I just need to check out atmaxplorer ocassionally for the lastest CFW updates? Many thanks again.

        • atmaxplorer sylv3rblade October 21, 2009

          The GEN firmware doesn’t have the updater that the older, more loved M33 releases had so you have to check this site out for any further updates :D. You can subscribe by email if you want to 😀

  127. jetan_0692 Jennifer January 13, 2010 Reply

    I think mine is hackable because there is high chance that it’s not TA-88V3. Before OFW 6.10, I have CFW 5.03 GEN C… I just bought Pandora kits from I hope it will work…

    • billchat12 Shanmali January 14, 2010 Reply

      Tell me if it works. 5.03 GEN C works on TA-88v3 as well. so that’s no deciding factor, but I hope it works.

    This is an excellent guide, but after reading through it, I am still unsure if I can successfully load cfw on my PSP.

    The box that my PSP shipped in has the letter G on the side, which according to your guide means that I cannot install cfw, however all the other checks indicate that I can.

    OFW – 3.95
    Serial starts with HA
    Date Code – 8B

    The last thing I want is to brick my PSP, so what can I do to clear up the confusion?

    • atmaxplorer sylv3rblade March 9, 2010 Reply

      Just upgrade to 5.03, run chickhen and run PSP Ident. That’s the surest way of knowing if your PSP is hackable.

    hello sylv3rblade. I have a PSP-3000 and is already hacked with Chickhen Mod 2 and has a System Software of 5.03 GEN-C(Full). I can play almost every PSP games with it too. However someone warned me about having an update in Wii and then talks about upgrading the firmware version (which I am afraid will happen since I won’t be able to play ISO games anymore). So can I ask what things to avoid so that my PSP’s CFW will not be upgraded?

    • atmaxplorer sylv3rblade April 12, 2010 Reply

      Just don’t use the network update feature on your PSP’s XMB nor allow anyone else w/o proper warnings about not upgrading to use your PSP. If you’re just using the PSP to play games, listen to music, do a bit of homebrew, you’re in no danger of upgrading your PSP’s firmware 🙂

      • venjuliene_corpuz Veejay April 12, 2010 Reply

        ah when we bought the PSP, the store owner told us about not letting the battery run out or else it becomes “default” is what he said and that the files like GEN-C and Chickhen might be deleted. What does this “default” mean?

        • atmaxplorer sylv3rblade April 12, 2010

          That simply means that your PSP will revert to the official firmware and you’ll need to reinstall chickhen and 5.03 GEN-C.

    hi.

What will happen if i don’t use the unit for a few days? thanks in advance.

    • atmaxplorer sylv3rblade April 19, 2010 Reply

      Yep, it will revert back to it’s original firmware once it turns off for any reason. If you simply leave it on standby, it won’t affect the cfw 🙂

    Hello Mr. silv3rblade. Meron lang akong gustong i-confirm. Ang 3.90 M33-3 custom firmware na ba ‘yon? Kasi kung oo di puwede na akong mag-update ng CFW ng walang limit di ba, at hindi ko na rin kailangang alamin pa kung completely hackable na ang PSP ko o hindi? Sensya na medyo bago sa ‘kin tong firmware e.

      Kapag 3.90 M33 ung firmware mo, no need to confirm if it’s hackable or not. It IS hackable (kasi naka 3.90 M33). Ang non-hackable PSP usually starts with 4.01 ofw.

    Just wanted to say fantastic post. There is a lot of confusing information on firmware. I’ve spent the last 4 hours reading up on it.

    Im still not really clear on how to go about getting my hands on a hackable psp. I would like to get a 3000 series as seen here at ebay: but from what I understand the firmware has a good chance it would already be above 5.03. I have asked the ebay seller a question on the firmware hopefully I will get a positive reply.

    If possible can people that already have this model (3000 – 3006series) psp indicate if they have had any luck in hacking it?

    The other alternative I’m looking at is buying a second hand 2000 series from

    Your comments and thoughts would be appreciated.

    • atmaxplorer sylv3rblade May 8, 2010 Reply

      PSP-3000s are really a tough buy especially if you’re looking into installing CFW on them AND you don’t have a brick and mortar store to buy from. 🙁 The best bet for getting your hands on a hackable PSP is to buy secondhand (which can be daunting yes but I can tell you first hand that it’s usually worth it, I got my hands on a secondhand PSP-1000 unit :)).

      As for hacking PSP-3000s, no word on when a “new” firmware is coming to help people above 5.03 firmware.

    Hi I mean the American version.(i dont understand japanese)

    I tried the one on torrent(i think 1350+ mb size) but it gave me “couldn’t start the game errror.”some 18002048 error i think”.
    So i tweaked around few recovery mode settings changed the drivers from M33 to other ones and tried changing kernel from 5.xx to 1.5 too and also enabled/disabled plugins,installed KHBBS plugin(and enabled it) too but it made no difference

    So what i did was i patched it using tools like WOSG UMD,promotheus and prxdechack. I patched it alright I mean i did everything perfectly accrding to the tutorial and the final outcome showed up like the one provided on tutorials final screenshot but when i start Peace Walker it shows the white psp screen with usual sound and then after a while screen goes black and after a while the PSP turns off by itself.(maybe you can figure out whats going on here).

    So what I am trying to do right now is trying to download the European version of the game.and Ill let you know in few hours time if it works but from what ive heard European version freezes randomly too on gen d3.

    ok.. so what you’re saying in the above instructions is, as long as its not HU2 its completely hackable? or what? mines HU0 like the pic, so it isn’ counted in the “partially hackable only” bit, right?

    i ask because chickhen doesn’t like me right now and won’t hack for the past 2 days so..

      Chickhen won’t run unless you’re specifically on 5.03 ofw, is that your current firmware version?

    Yo sylv, I just want to ask if I can play UMD ISO games on a PSP Go?

    Is there ANYWAY I could play an iso on my psp go?
    1.PSP GO
    2.The letter is C.

    • atmaxplorer sylv3rblade March 1, 2011 Reply

      There currently is no way for you to downgrade your PSP Go (and allow you to play ISOs) as your current firmware is 6.37. There is however a Hen available for your firmware which will allow you to run homebrew. Again no ISOs.

  201. metalshredder1990 executable19 March 1, 2011 Reply

    I’m sorry, I forgot to mention, I’m on 6.37, if it is not released yet, can you tell me approximately when?

  202. metalshredder1990 executable19 March 1, 2011 Reply

    And can you downgrade a psp go WITHOUT a Pandora Battery?

    Please help me! I once contacted help in a gaming store and they told me that my PSP only supported 5.03 GEN-C because my PSP can’t create a Pandora battery, but my PSP is currently TA-088v1/v2 and my PSP version is Slim v.20/2.1. So is my PSP hackable or not? Please, anyone help me ASAP!

    um sylv3rblade i just want to ask if it is possible to change 5.50 gen b full to 5.50 gen d3.

    Hello? Can anybody have an answer on my situation? And my PSP also had 3.80 M33 installed back then but I wasn’t sure if it was M33-5 or 6, and my box’s identification letter is probably F.

    • atmaxplorer sylv3rblade April 11, 2011 Reply

      If your PSP had 3.80 M33 then your unit is completely hackable.

  208. chrisj_15 chrisj_15 April 12, 2011 Reply

    Ok, thank you sylv3rblade! I wondered for how many months if my PSP is hackable or not.

  209. greymane1992 saint dusty April 22, 2011 Reply

    will a new version or anything like checkHEN be created to support 6.38 in teh futures?

    • atmaxplorer sylv3rblade April 22, 2011 Reply

      Unless a new exploit will be discovered that’ll give kernel access, I highly doubt it. HBL is available for 6.37 but there’s no ISO support since that’s been patched too.

        • atmaxplorer sylv3rblade August 19, 2011

          Your only recourse is to purchase a Pandora Battery as there currently is no confirmed working downgrader for 6.60.
