  • Firmware: 5.03 or below

How to Install Custom Firmware (CFW) on PSP

Step 1 – Update PSP Firmware to 5.03

Skip this step if your PSP is already on Firmware 5.03.

If your PSP firmware version is below 5.03 you need to update it to firmware 5.03 first.

Connect your PSP to computer via USB. Your PSP memory stick will appear in your computer.

install custom firmware on psp (1)

Open the Memory Stick drive from your computer and copy EBOOT.PBP from PSP_Firmware_503 folder to the following directory on your memory card:


(Create the directory if not available. Make sure you name folders in CAPS)

install custom firmware on psp (2)

Now Press the O button of your PSP to disconnect it from USB. Now go to Game > Memory Stick on your PSP. There you will find the PSP firmware version 5.03. Press the X on PSP button to execute it. It will install firmware 5.03 on your PSP.

install custom firmware on psp (7)

Step 2 – chickHEN R2

Assuming that your PSP is on Firmware 5.03, now is the time to load chickHEN R2. Reconnect your PSP to your computer via USB.

Copy h.bin file from ChickHENR2 folder to the root of your PSP. (ms0:/)

install custom firmware on psp (3)

For Phat (PSP 100x)

Go to PHAT folder in chickHEN R2 folder and copy eggsploit.tiff file to the following directory on your PSP:


(Create the directory if not available. Make sure you name folders in CAPS)

install custom firmware on psp (4)

For Slim (PSP 200x)

Open the SLIM folder from ChickHENR2 and Copy folder ChickHEN to the memory stick under:


install custom firmware on psp (5)

Step 3 – Hellcat’s Recovery Flasher

Copy RECOVERY folder from Hellcat’s Recovery Flasher folder to the following directory on your PSP memory Stick:


install custom firmware on psp (6)

Step 4 – Load chickHEN R2

Now it’s time to unplug your PSP from the computer and load ChickHEN R2.

From your PSP, Go over to Photo > Memory Stick and click on the FAT folder (if you have a Phat) or ChickHEN folder (if you have a Slim). The screen should blank out then flash green, showing that ChickHEN has loaded. The PSP will then reboot automatically.

If it just hangup and shutdown PSP then your got to retry until it automatically reboot your PSP. It may take a few tries to work, in fact it took me 7 tries to get it to work. Here are few tips to get it working:

  • Make sure there is no UMD in the drive
  • The USB cable is unplugged
  • Restore default settings under System Settings may help

Phat (PSP 2000)

install custom firmware on psp (8)

Slim (PSP 1000)

install custom firmware on psp (9)

Step 5 – Load Hellcat’s CFW Recovery Flasher

Assuming that ChickHEN has successfully loaded.

Now on your PSP scroll over to Game > Memory Stick and load Hellcat’s Recovery Flasher. When it loads, choose I agree to the notice informing you that the program touches internal flash.

install custom firmware on psp (10)

A brown screen menu will appear. Scroll down to Install M33 CFW and press X button. Then you will be asked if you want to reset your settings. Choose the first option (reset).


Then it will start install Custom Firmware on your PSP. When all done, press the X button and turn ON your PSP manually.

Go to Settings > System Settings > System Information and see what:

install custom firmware on psp (11)

Congratz! You have successfully installed Custom Firmware (CFW) on your PSP. Input your desired settings again and enjoy 5.00 M33 on your PSP.

Thanks for help to install custom firmware

uhh... November 5, 2009, 11:50 pm

how does it go to 5.00 m33 if we started with 5.03? 😮

im trying to do this on my psp 1000

trickYguY November 7, 2009, 3:01 pm

Good Q :p
yeah you updates ur firmware to 5.03..
but the one living inside Recover flasher is 5.00 M33-6 which is CFW. and is installed in the end..
that’s why you get 5.00 M33-6

niceblokedave November 6, 2009, 4:32 am

Looks like a great easy guide !! just 1 question though before i try it 🙂 . On the PSP phat if the psp is powered off after the install is finished will you have to install again ? . I have read on the PSP 3000 you can only put it in standby to avoid this happening but not clear on the phat

trickYguY November 7, 2009, 2:57 pm

it happens with partially unlockable PSPs like 3000
PHAT is completely hackable so there’s nothing to worry abt 🙂

niceblokedave November 8, 2009, 12:48 pm

Just wanted to say THX !! . I have been looking around the internet for a couple of weeks for a guide on installing custom firmware and was picking up bits and pieces but nothing i could string together clearly from start to finish that i was convinced would work( pandora battery or not, which custom firmware etc). Your guide worked a treat and i’m now on 5.03 m33-6 !! . Happy happy happy . Thx once again for your clear guide and links to software . Top job 😉

trickYguY November 9, 2009, 3:18 pm

Stay tuned for more upcomings for PSP

christophe January 31, 2010, 6:28 am

Hello i’ve got chickhen installed and then the cfw 5.00 M33-6, everything worked !!! But when i tried to play homebrew games (iso) my psp says (this game can not be started these data are damaged) what can i do about it? I can’t find a sollution.

timi September 20, 2010, 11:27 am

hey you can use the “m33 vsh menu” or push the “SELECT button” then you can see the “UMD ISO MODE”‘S deafault VALUE is “NORMAL” change it in “M33 DRIVER” by pushing the (>) button,.,. i hope it will help you a lot.,,. THANKS,.,.

niceblokedave November 8, 2009, 12:59 pm

oops . Meant 5.00 m33-6 of course

lisod November 6, 2009, 9:58 am

Thanks for the PSP guide

Bala November 11, 2009, 11:06 pm

I was using firmware 5.00 M33. Recently i upgraded it to 6.00. Now the problem is, I cannot play ISO file from M:ISO.
Whether i can degrade it back to 5.00 M33 or any other software has to be installed to play ISO files in version 6.00 itself?
Please someone help me to solve it out.

Anders November 16, 2009, 4:48 pm

You guys are a great inspiration! Keep up the great work.

Kk November 16, 2009, 11:06 pm

Thanks trickYguY for the help! just want to know after installing the custom firmware there are new files created like egghunt.bin and old ones h.bin and recovery should we keep the files or delete them? and having trouble loading games it says ‘game could not be started (80020321)'(final fantasy Dissidia) is this because I need to upgrade to a different version of this firmware? the ISO folder is on the root of my memory stick. Thanks

trickYguY November 17, 2009, 6:08 am


Try this
1. Hold the power button for 4 seconds to Turn off the PSP
2. Turn on PSP while holding the R trigger to enter into the recovery mode
3. Open Configuration settings and locate UMD Mode setting
4. Keep press X button until you get this option UMD Mode (currently: m33 driver – no UMD -)
5. Go Back and Exit from recovery mode

Kk November 17, 2009, 11:47 am

Thanks for the fast reply. Its all working fine now also I didn’t have a UMD inside before but when its inside it works too^^ and I have notice that some games don’t work because it’s a bad file lucky I got afew different versions of the same game haha. I still haven’t deleted any of the h.bin, egghunt.bin files just incase something goes wrong hope this doesn’t affect the firmware??

trickYguY November 17, 2009, 3:30 pm


Great, Yes you can delete now h.bin and egghunt.bin files

Liamsell November 29, 2009, 10:07 am

will this work on all psp 2000?, or only the select few which are hackable? ive been trying to get the tiff exploit to work. no luck so far after about 20 tries

trickYguY November 30, 2009, 2:16 pm

This will NOT work with PSP-3000s [TA-090v2] or new PSP-2000s [TA-088v3]

My PSP is psp2001 slim (silver body). It has the version 4.02U on it. So can this be done. what do you suggest I do first?if it bricks can I fix it? Is what you listed on here an emulator too?

leonmayank December 16, 2009, 12:24 am

if some of the isos n csos r not working in ur custom firmware it is because the game requires greater firmware…but i hav a software which decrypts the iso/cso file n rebuild it according to ur firmware..i wanted to play fifa 2010 but it wasnt working on my 3.90 m33-3…but i decrypted the iso file n rebuilded it…n yipee its working…if anyone need this software let me kno..i will be glad to help!!

Will the ChickHENR2 + Recovery work on any filmware (My psp is a 1002 with 4.05 filmware) Will it work?, This is because i have not got a battery for the install of the 5.03 filmware. Thanks.

anil March 1, 2010, 12:51 pm

hi thanks for the post
i am all done but got stuck at a final point while working withh hellcat
it throws me a error in detecting fm while installing cfw
plzzzzzzzzzzzzz help me out
every thing else went well
i am using psp slim 2000 ta 085v1

sirhc March 10, 2010, 10:33 am

Had difficulty also running hellcat recovery.
But i figured it out that it requires OFW 5.0.
Copy EBOOT.PBP of the OFW 5.0 to MS ROOT,
then rename the EBOOT.PBP to 500.PBP
Run again hellcat.

bdw, the system will reset to VERSION 5.03
if you fail to load hellcat properly.
If hellcat recovery fails, “Do NoT EXIT”
choose >Launch another app from /PSP/GAME…
and if you have PSPident, click it so that the
system will not reset and you will not again
run chickHEN.

Hope this helps.

Thanks trickYguY for the instructions.

thgink March 11, 2010, 3:32 am

when i tried to open Hellcat’s Recovery Flasher it says This game cannot be started.The data is corrupted.

sirhc April 7, 2010, 11:47 pm

The “data is corrupted” error message appears when the chickHEN R2 is not yet properly loaded.

Make sure that you properly followed Steps 2 – 4
and take note when loading chickHEN R2:
The screen should blank out then flash green, showing that ChickHEN has loaded. The PSP will then reboot automatically.

If it just hangup and shutdown PSP, then you got to retry until it automatically reboot your PSP.

okay, I think I know what the response to this will be but, I’ve got a fat PSP which since I’ve never really used the CFW on and needed to update to play one of the games I got recently, I decided to update it to 6.00, is there any CFW out there that work with 6.00 or am I going to have to go pandora to play ISO’s?

Anom July 22, 2010, 3:35 am

Thank you for this! It took me a while but I got it and it works perfectly!
One question…
Can you delete the Hellcat program after you updated to CFW?

Hey Guys, Im new to CFW and need some help. Anyways, I just installed 5.0 33 CFW or whatever on my FAT PSP. It says that it worked, and when im at Home on the PSP menu if i hold select it comes up with a new menu. When I load my game (MH2 Freedom…), I don’t understand how to get to the CFW code. I heard you hold like select or D-Pad up, but thats not working. Do i need to change a setting or something to allow me to view the CFW menu while playing a game?

I’ve got a psp 1K with OFW 6.35. I’m having difficulties downgrading (it keeps telling me there is no need to update), is this possibly due to the fact that I have the latest OFW or am I doing the guide wrong? Keeping in mind that I’m completely new to this stuff.

mhm i have 6.60 PRO-B10 if i install the chicken does games will work or i have to downgrade fw and then install CFW?

kesra December 18, 2011, 8:01 am

Howdy folks.

Couple of hints.

1) This is not the page to look at if you have a newer 2000 or if you have a 3000. Go to the other page.

2) Yep, the Recovery link here is dead. That’s OK. Google “hellcat’s recovery flasher” to find the link for download. I got it in less than a minute.

3) Good luck!!

I’m still on my way to “freeing” my PSP I just bought. So far so good, it’s a used PSP-1000. Dude at the store was like “Uh, you don’t want the new one?” Nope!

Markos January 5, 2012, 5:06 am

Can i delete everythink after i’m done?

Elizer January 20, 2012, 8:19 pm

does anyone has ChichHEN R2 and Hellcat’s Recovery Flasher here?the one in this site is broke and not available already. Please give me please please!

stevenhill321 January 31, 2012, 6:10 pm

Ok after a full weekend trying to get chickHEN R2 to load on to my PSP and Hellcat recovery 1.65 (which also didn’t work) nor the other vesions of HELLCAT, I might add, I have finally sussed out what to do. I have read so many posts and done this from scratch but each time I get to the Hellcat recovery screen it ‘errors’ on me or the program couldn’t find the correct 5.00 version and there were some other reasons it wouldn’t load but I can remember them all.

First up, chickHEN is a b*tch to load, end of!!! It will work eventually but you have to have lots of patience and realise that there is a set procedure of a sort to get this to work. It is very much a trial an error but it is worth it in the end, I assure you.

Anyway I have a white psp TA-082 motherboard with OFW 3.11 running on it. The only way to get 3.11 upgraded to a CFW (preferably 5.00 M33 6) was to buy a pandora battery right?
Wrong, the battery was rubbish, didn’t fit in my machine to even charge up let alone get it to run. I had to sit there holding this thing in but after a few flashes of the battery light it stopped and did nothing. The instructions said hold L shoulder button whilst turning on the unit da da da but nothing happened. Probably defentive or incorrect software on MS or both. I dunno, but it was certainly a waste of time and money.

Now chickHEN R2 is what I did to get this working but boy was it difficult at first. I am no way a noob but come on, if you havent had to go down this route before then aren’t we all? People who think they are the dogs and knock people who don’t know make me sick and are no credit to the gaming world. I hope to put together a comprehensive guide so people don’t have to go through what I had to to get this to work.
Anyway, I digress. here goes with what I had to endure. I will guarantee that if you follow this guide to the letter then it will work but you have to pay attention!!!!!

If you haven’t already got the official Sony 5.03 firmware (fw) then download it and install it. Put the eboot in a folder and rename the folder (not the eboot) to ‘UPDATE’ (in capitals) then drop the eboot inside the folder. link your PSP to your computer and put this folder called ‘UPDATE’ in the PSP/GAME folder and leave it there.

Now, unlink you USB from the computer and turn on your PSP. Navigate to the memory stick and you should see the update. Make sure your battery is fully charged or better still plug in your mains adapter and click on the update. The psp should start updating. DONT turn off the psp or turn it off at the mains whilst you are doing this. Be careful and basically just pay attention.

Ok after a short while the unit should have updated. Scroll to you system settings on your PSP and it should read 5.03. To run chickHEN R2 the PSP ‘NEEDS’ to be on 5.03 official firmware, not 5.00 or anything else just 5.03. So if you haven’t already got 5.03 then go and get it and install it now.
Once the PSP states that it is 5.03 then you are doing great. Next go to your computer, format your memory stick from the system settings. It is important that you do this.

Next download chickHEN R2 (R2 stands for ‘revision 2’). Now when you download this it will give you a RAR file. Make sure chickHEN R2 is for the PSP PHAT and not the slim version. I think it should work anyway but just make sure that it is for the PHAT PSP.

The difference being is that the one I downloaded had five GIFF files which looked likes egg yolks yet the other download only had one picture of a coin or something of that nature.
Anyway unpack your download with WINRAR or whatever. You will see an exploit file which is a TIFF file and a H.bin file. Take the TIFF file (it has to be a TIFF file and not a GIFF, I say this because my download was a GIFF file that was never going to work) and put it in your PHOTO folder, If you don’t have a PHOTO folder put the tiff file in PICTURE instead.

Next put the other white file H.BIN in the root directory (the first screen that you come to when you connect your psp to the computer) don’t put it anywhere else.
Download HELLCAT 1.65 or 1.50 recovery program. Any is fine but the later versions do not specify the ‘install M33 on the options. Its only the old version 1.50 that says that but don’t worry as they all do the same thing. You will see what I mean later on.

Put the HELLCAT RECOVERY folder in to your PSP/GAME directory. Next download the official 5.00 eboot for official firmware. Don’t download 5.03 or any other version just the 5.00 and make sure that it is the official version. When you have done this rename the eboot to 500 (not 500.PBP) as it is already a PBP extension and that would just make it 500.PBP.PBP which is wrong).

This is where I was going wrong I think.I just made sure that I had this file everywhere so the PSP could not give me any excuses that it couldn’t find it, like it had been doing.So copy this 500 file and place it into the PSP/GAME/RECOVERY folder and then copy the file on it’s own just below the RECOVERY folder..Then make a folder named ‘UPDATE’ and drop the 500 file into that as well and put that folder into the RECOVERY folder and underneath the RECOVERY folder. Then put the ‘UPDATE’ folder on your root directory (just to make sure) and a loose 500 file below that also on you root directory. Remember the more places you can put it the more chance you have of it working.

It may seem over the top and it is for sure, to put this 500 file in so many different places but I am not actually sure other than the root directory where this file is supposed to go. It should actually just go into the root directory (as all the threads suggest but so what if you have more than you need.
OK now, go to retore default settings on your PSP and go through the instructions. The PSP will then reboot. Change your character set in your system settings to U.S and turn off UMD auto start to off. This is very important as this seems to improve the chances of ChickHEN acually loading.

Now scoll up and down on the menu screen of the PSP. I don’t think this actually does anything but the more you try the better chance of it working. Click on the PHOTO/PICTURE on your PSP. Be very patient as this does not always work. In fact it works 3 out of 10 times but it WILL work eventually. As a tip I would just keep you battery lid off as taking this on and off will eventually drive you mad unless the PSP start up music gets there first. Work on clicking the X button immediately you see the TIFF file on the PSP.

Eventually the screen will blink green (I think) and it will look corrupted, then the PSP will reset itself. You are now officially running chickHEN R2 and if you don’t believe me then check you system settings. Just remember to be patient and it can take ages to get this to eventually work. It is a major achievment just getting this far but you will not have to do all this again if you can get to the end and install the custom firmware, so persevere.

Carefully put the PSP battery lid back on but be careful as turning the PSP off or dropping the battery out of the PSP will reset you back to 5.03 and you will have to install chickHEN all over again and believe me you don’t want to have keep getting chickHEN to run on your PSP.

OK, once chickHEN is running simply navigate to your memory stick and click on the HELLCAT installer, which ever version you have should be fine, just bear in mind that only the HELLCAT 1.50 version will show up the ‘install M33 cfw’ option. I was looking everywhere for this and couldn’t understand why the screenshots on the threads I was viewing on the net showed this option but my version didn’t. It’s only because the version on the net is the older 1.50 version.

Once you in HELLCAT simply follow the instructions and enter the program. Click on install M33 custom firmware or whatever it says (it is just the top line option anyway) and make sure it directed to install 5.00 as you can pick which version you wish to install.

Click on reset settings, which is the next option underneath and the PSP ‘should’ install the custom firmware 5.00 M33 4 on to your PSP.

Should you decide that you want 5.00 M33 6 then just download the cfw 5.00 m33 6 off the net, place the eboot in an update folder and put this in PSP/GAME and run the update from your memory stick just like you did when you originally updated your PSP with 5.03 at the beginning of the tutorial.


Mel May 16, 2012, 2:15 am

“Next download the official 5.00 eboot for official firmware. Don’t download 5.03 or any other version just the 5.00 and make sure that it is the official version. ”

I think that’s what saved me, I assumed the 5.3 Eboot I used to update my PSP would be the same file I needed to change to 500 – completly wrong.

Mega big thanks for thanks!
