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 
Requirements:
- PSP Phat or PSP Slim with 3.52 M33 or higher. If you don’t have custom firmware yet, READ: Convert your PSP to custom firmware.
- PSP battery that’s at least 78% full
- Download: 5.00 M33 | 5.00 M33
- Download: 500.PBP | 500.PBP
- Disable ALL plugins.
- Back up your save files (so that if they get corrupted, you still have backups)
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
STOP!!!
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.
i follow all of your instructions but when i go to my psp xmb and the game section on my memory stick i get corrupted data, what should i do
Rename the Eboot.pbp back to 500.pbp.
ok when i run the update for the 5.00m33 it runs it and when it gets to 99% complete it says error contact tech support and gives me this (FFFFFFFE)…..can anyone help me out?
I also encountered the corrupted data .. u must transfer only the UPDATE folder not the whole 5.00 m33
i followed all the steps above. sad to say after updating my psp which was on 4.01 m33-2 CFW to 5.00 m33 I can’t find any games on the games memory card nor I can’t update the firmware to m33-6! what did i do wrong? could you guys please help me out.
if i was to check it looks like that the upgrade was successful from 4.01 to 5.00 but I can’t update 5.00 m33 to 5.00 m33-6.. it says cannot load game. data corrupted.
help pls. help
You’re sure your PSP got updated to 5.00 M33 and NOT 5.00?
Hi, i own a PSP 2000 running on 3.80 M33-5.
i followed the steps on upgrading to 5.00 m33 mentioned above but it does not prompt me to correct idstorage keys or install 5.00 SONY.
It stated unpacking… Done and ask to wait.
After that the software just restart. And i check the system info it’s still 3.80 m33-5 ver.
Any idea why it’s not working for me?
Hmm.. do you have any plugins enabled when you installed 5.00 M33?
What plugins you mean? Is there anything settings i need to config b4 the upgrading?
guys i need help, when i install the v.5.00 to the psp and i went to the games i saw the update psp v.5.00, when i finished updating it my old games are gone even my adhoc file transfer and i can’t open the recovery menu on the psp, what should i do?
You updated to the official firmware and NOT the custom firmware. You need to install custom firmware on your PSP again. Just follow the guide below:
http://www.atmaxplorer.com/2009/07/convert-your-psp-to-custom-firmware-without-pandora-battery/
I’ve mistakenly did such stupid thing.
I thought I have to update to 5.00 first before going to 5.00 m33-6, so I update my PSP to 5.00 without including the m33-6 update.
When I want to update to 5.00 m33-6, it said “game data is corrupted”. I can’t connect to PSP update either.
Please help..
I can’t play my games anymore (it disappeared from the list)
You need to install custom firmware on your PSP again. Since you’re still just on 5.00, you can install it without needing a Pandora battery. Just follow the guide below:
http://www.atmaxplorer.com/2009/07/convert-your-psp-to-custom-firmware-without-pandora-battery/
Err, but my PSP is PSP 2000 (PSP Slim), is it safe to do that?
If your PSP has had custom firmware installed (before you updated to 5.00), then yes. If you’re not sure. READ: Is my PSP hackable?
hi,
recently i just wrongly updated my psp 1001 to official 6.10. can i revert back to custom firmware 5.00 M33?
You need a Pandora Battery to downgrade your PSP.
it’s me again my psp model is 2001 or 2000 so i was wondering how to instal custom firmware?
# 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?
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).
That 500.pbp I d/l from above – is that not the official one too?
i updated to a GEN D 5.50, and wish to change to a m336. however, when i run the m336 installer is says ”the system software of your psp is version 9.90″. is there anyway i can downgrade back to m336?
You can’t directly downgrade by using the same way you upgraded your custom firmware.
Use the Hellcat’s Recovery tool on this post and downgrade at will
Hi guys i need help, I tried the steps above and was successful in upgrading the 3.71 m33 to 5.00 m33 but when i look at the games in the XMB It’s saying that there are no games.. What did i wrong cause when i try to patch to 5.00 m33-6 the updater wont show in the GAME. How can i fix this, Thanks and Regards….
i own psp2000 TA-088v3.
the problem is my device reboot and the previous cfw(done by fren) is gone.

Please help me, after installing the above procedure my psp says version 5.00 however when i install the update it says this could not be started please help

Please help!
You upgraded to the official firmware, not custom firmware.
Follow this tutorial to install cfw again without pandora:
hi…sorry for bothering…but i really need help..should i update my 3.71 M33-2 to 5.00 M33?? i have a 500.pbp file which is 26472 kb and a eboot.pbp which is 458kb in the folder. I have not put it into the game folder yet..but should i do it?? Plz reply..
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 PSP_500_FW_UPDATE.zip.
thx..i updated already..works perfectly..thx alot..

Hmm.. upgrade ka muna to 4.01 M33 before upgrading to 5.00 M33.
sylv3rblade – sry to ask stupid question , but
i just download tekken 6 and final fantasy dissidia , but i cant play it, my version is 5.00 m33 – 3,so should i upgrade it to 5.00 M33-6?or to 5.50? and i just follow ur intruction?do i need pandora battery or Magic MS? and my psp is slim 2000 bought it in 2008, because i scared i will do something wrong to my psp=S
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.
err,how about the version txt?where it let u make ur psp think is version 5.50 firmware…but the only problem i have is i cant seem to find
(Browse your PSP and go to folders VSH > etc. Inside you should see a version.txt file.)
nvm…i try already…still cant work…going dl again…is 5.00m33-6 stable?should i upgrade it to that version?or i just stick with 5.00m33-3?
ok, so i installed the 5.00 and it worked. and then i installed the patch -6 and that worked..after that, no other patches work, i get an error saying: “this update or a higher one has already been applied” . i have a game called disgaea 2:dark hope days that gives me the error code: 80020148 saying the came couldn’t be started.
help?
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.
i have tried to dload and put the update cfw 5.00 m33 in my psp 1k. however, when i click at the game/update/5.00 m33. it just appear black screen with
unpacking… done
Please wait…
That’s all.. please help.
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.
The current version is 5.03 ofw. i have run the ChickHen R2.. before i run the 5.00 M33 update.. I have tried run the 4.01 M33.. but it shows the same problem…
unpacking done..
Please Wait..
Before that, I have tried use pandora + Magic MS.. Supposedly it shows the 5.00M33 installation page.. but it goes straightly to the M33 Recovery Menu…
Please help!! TQ
Errr.. you have 5.03 OFW.
Read this tutorial: http://www.atmaxplorer.com/2009/07/convert-your-psp-to-custom-firmware-without-pandora-battery/
I have a PSP 2001, With Firmware 5.00 , My psp is completely hackable , I installed it with my pandora battery and rains ultra lite mms maker , I have the 5.00 m33-4 EBOOT.pbp file , but when i load the menu with my pandora battery ( boot it by holding L after inserting my pandora battery and MMS) I select the install 5.00 m33 option , i get error , invalid 500.pbp file . I know there is nothing wrong with the file , i just want to know , why can i not install this ?
can i directly upgrade to Firmware 5.0 on my psp slim from 3.xx m33 firmware… i forgot what exactly my firmware is but i know its still 3.x version…
Can i directly upgrade CFW?
thanks,
slick
If you have at least 3.71 M33, you can but it’s not recommended (too many things can go wrong that’ll lead to you bricking your PSP).
i have 5.00m33 and am trying to update to 5.00m33-6 and when i run the update it says “The game could not be started. (FFFFFFFF)”. I can’t figure out what I’m doing wrong
ok i got it to work by executing it after i used chickhen and without using the cfwenabler. However, it now just says this “unpacking… done. Please wait…” and it stays like that without doing anything. I’ve tried updating to 5.00m33-2 and 5.00m33-6. Both had the same outcome.
Chickhen? CFWE? Are you installing 5.00 M33 on a PSP-3000?
I also got then same result…I run 5.00 M33 with 500.pbp but it stop at “Please wait”..
Hope somebody can help..
What’s your PSP model and current firmware version?
i cant update ny psp to v 5.0 m33… my psp version is v6.20 and psp 2000…

HELP ME sylv3rblade ……. plzzzz
You can’t install 5.00 M33 over a PSP with 6.20. You need to downgrade your PSP to be able to do so but not all models can be modded this way. Please read this guide to see if your PSP is hackable:

reply pleasseee!!!!!!
Please read the firmware requirement, it says at least 3.52 M33. Try updating to 3.52 M33 or 3.71 M33 or 4.01 M33 before installing 5.00 M33.
my psp says i have 5.00m33 but it can still run tekken 6 so i don’t think i need to go to 5.00m33-6. its a psp-2000 and i have no idea what firmware its running because i got a friend to hack it
hi, i’m using PSP1000 and 5.03 OFW version
I am on 3.52 m33-4 and when i try upgrading it just says please wait…. and never does anything. for other firmware upgrades it says i need to be at 3.52-m33-4 even thou i am already at the firmware. ANY HELP PLZ
This is the usual problem when upgrading from 3.52 M33 to 5.00 M33. Try upgrading to 3.71 M33 then 4.01 M33 before installing 5.00 M33
okay. I tried upgrading to 3.71 m33 but when i execute the program it says program requires 3.52 m33-3 or higher and im on 3.52 m33-4. why is it no recognizing my firmware ? Any help would be appreciated.
Thanks

Please check if your PSP is hackable before anything else. Once you’ve determined that, I can point you to the right direction on what firmware to install.
I had a psp-2000 running 4.01 m33-2 cfw.
I performed the above steps to upgrade to cfw 5.0 m33, but after the installation, it has gone to 5.00 official sony firmware, dunno how that happened!! I had renamed the official firmware file from eboot.pbp to 500.pbp.Did I do anythn wrong over thr? How to revert to my earlier cfw or go to cfw 5.0 m33?? HELP!!!!!
You failed to copy one of two files… No worry, you can still fix this by following the guide below:
http://www.atmaxplorer.com/2009/07/convert-your-psp-to-custom-firmware-without-pandora-battery/
Thanks a lot!!! It worked, first installed chickenhen R2, then cfw 5.00 m33. Now for 5.50 GEN-D3..CHEERS!!!
Works like a charm right?
Yup!!!
my psp is hackable bec. it it was installed by chickhen R2. its version is 5.03 tnx man…
hey mine also said unpacking done… pls wait…my firmware is 5.03, and i already installed chickhen r2
my psp model psp slim 2000
Please read this post and run PSPIdent:
http://www.atmaxplorer.com/2009/03/how-to-check-if-your-psp-can-have-cfw-installed/
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 :/
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.
sylv3rblade, I really need a point in the right direction, i’m literally stumped here.
Don’t know my motherboard type, it’s the old school black-chubby psp. I’ve upgraded the firmware to 5.00 (don’t believe i have m33), I’m trying to simply play bleach heat the soul 6 (no umd).
I’ve tried the other steps on various forums links, and keep ending up with “corrupt data” when I rename eboot to 500.pbp.
Help! lol
You can’t play any games in ISO format w/o cfw. Follow the instructions linked below:
http://www.atmaxplorer.com/2009/07/convert-your-psp-to-custom-firmware-without-pandora-battery/
can i have a little help plz?
when i download it and try to unrar it it says
that the file did not pass crc check,or when it start to it says something about a bad heading….
its no prob any more…..i swiched the extractor program
had my buddy at work re-hack, apparently i must have in a drunken stupor done a normal update, and lost the hack cfw.
he fixed it back to 5.00 m33-6, in the process of readding my games to the ISO folder now, thanks for the response!
how can i update psp 3000

Nope. Pandora doesn’t work on PSP-3000s. Once you upgrade over 5.03, it’s game over.

* Extract the 5.00 M33 installer files to your computer.
* Copy the Update folder to X:/PSP/GAME/ on your PSP’s memory stick.
