How to Install Custom Firmware 4.01 M33-2 on your PSP
Dark Alex has done it again! What should we ever do without him. The most awaited custom firmware has finally been released. Now, I know this post might be a bit late, I’ve been having problems with my DSL connection and I haven’t been online for days, but I know a lot of you guys are still waiting for this. It is true time to turn out to be a mcp via grasping unsurpassed microsoft certification as mcts.
So what are the new features of this custom firmware? This new custom firmware has all the features the 4.01 official firmware has plus a few extras. Many people are asking me if it’s worth installing it and my answer is a YES. I have 4.01 M33-2 custom firmware installed already on my phat PSP and I haven’t encountered any bugs yet. But don’t take my word for it. Try it yourself. You can always revert back to your old 3.90 M33-3 if you want.
So much for the rambling. Here are the instructions on how to install the new custom firmware on your PSP.
Requirements
As always, please do check that you pass all the requirements before you can do the installation.
- A Fat PSP or Slim PSP already installed with a custom firmware. At least 3.52 M33-4 custom firmware must be installed on your Fat PSP and 3.60 M33 for the slim.
- A fully charged battery. I know it will run on 70% battery but 100% battery with the AC adapter plugged is the safest setup.
- A USB cable to transfer files from your computer to your PSP.
- The 4.01 M33-2 installer pack that I created for easy install. Download the 4.01 M33-2 installer pack and unzip on your computer.
The Steps
The steps are divided into 3. Please follow the directions carefully. I will not be held responsible for any bricks. Do this at your own risk! But I’m 100% sure you won’t brick your precious PSP if you follow the instructions carefully.
Step A – Installing the 4.01 M33 custom firmware
- Connect your PSP to your computer using the USB cable. Open the Step A folder and copy the UPDATE folder to ms0:/PSP/GAME/. After copying, disconnect the PSP from your computer.
- On the XMB menu on your computer, navigate to GAME > Memory Stick and run the 4.01 M33 update. When you run the update, the screen turns black. Follow the text instructions. It will take you to the Official Sony Update screen. That is normal. Continue with the process following the instructions.
- The Sony Updater will run. Don’t turn off your PSP or interrupt the update. After the Update, you will be asked to press a certain button to restart your PSP. Do so.
- Congratulations, your PSP is installed with 4.01 M33 custom firmware now. On to Step B.
Step B – Installation of the 4.01 M33 update
- You can only do this if you are successful with Step A. Connect your PSP to your computer. On your memory stick, navigate to PSP/GAME and delete the UPDATE folder.
- Now open STEP 2 folder to your computer and copy the UPDATE folder to ms0:/PSP/GAME/. Disconnect your PSP from the computer once you are done.
- On the XMB menu, scroll to GAME > Memory Stick and run the 4.01 M33-2 update. Just follow the onscreen instructions and you’ll be safe.
- After the installation, you will be returned to the XMB screen.
- Congratulations on your 4.01 M33-2 PSP.
Step C – 1.50 Kernel Add-on Installation Guide
- This last set of steps is optional. You may do this or not. The next set of steps will be instructions on how to install the 1.50 Kernel Add on for the Fat PSP. Sorry slim owners.
- Connect your PSP to your computer. Open Step C folder and then copy 150.PBP file from your computer to the root directory of your memory stick. And then copy 4XX folder from your computer to ms0:/PSP/.
- Exit the USB mode and on your XMB, navigate to GAME > Memory Stick and then run the 1.50 Kernel Add-on program. Follow the onscreen instructions.
- After the installation is successful, you will be taken back to the XMB.
- Congratulations. Your PSP is now the same as mine, a full battle gear handheld. Place your 1.50 homebrews on the PSP/GAME150 folder.
Whew! That was long. I really enjoy writing these kind of stuff. If you have questions or comments, scroll down and leave your message. Thanks to the M33 team for the goodies especially to Dark Alex!

[...] Update: If you are thinking of installing this custom firmware, I recommend you to go straight to 4.01 M33-2. [...]
Stylemo! Thanks for your easy to follow guide, hehe suki
stylemo, i install 4.01 m33-2 through wifi pls advice me if i install all 3 important files
thank you ur the best bro
i have psp1000 jap, is that ok with 4.01?
and new feature can i watch tv psp ?
stylemo, do we need to disable the plugins before installing this?
@Kuchiki_Sakura: When I updated my PSP, I didn’t deactivate my plugins but it worked well. I think it’s the Custom XMB you have to deactivate first.
@Lanz41: Yeah you can install it on any PSP that has custom firmware installed already.
@rickyboy noob: I haven’t tried wifi yet. But I think if it should work, it would only install the firmware update without the Kernel add-on.
@BossChief: Thanks!
hi just wanted to ask…… is it okei if iupdate my psp with this coz my psp is:
slim psp
3.90 33-3 so is it okay if i update it using your step A?
coz before i had a phat psp and it was 3.80 m33
and i updated it using another guide and at 99% is said FFFFFFFFFFF77 ERROR and then
KABOOM!
instant brick
Stylemo, I have another question. Does the CXMB Plug-in still work and the POPS plug-in as well?
Hi Stylemo
my second question is
update is work fine, thank’s
can i watch tv on psp 1000 ?
@Lanz41: With custom firmware installed on your PSP, you can watch recorded TV shows or streaming videos from your computer but I don’t think it’s possible at this moment to watch live TV shows from live antenna or cable.
@Kuchiki_Sakura: Yes the CXMB plugin works but you must use a newer version. About the POPS, I haven’t really tried that yet.
thanks for the easy guide. question about the step 3
after update a, b what happen when i install c pls help
i’ve heard that official fw 3.9x has skype !!!
what is that for ?
and is cfw 4.01 has skype or not or only for that slim psp?
Thank’s, @Stylemo.
@pher0777: you can only perform step C if you have the fat PSP. Step C is the installation guide for installing the 1.50 Kernel Add-on. This enables you to run 1.5 based homebrew applications.
@Lanz41: 4.01 M33 has Skype of course. Skype is a phone program you can use with Wifi.
any options for those without WiFi connection like me(seems like step A requires WiFi connection)?
thanks
stylemo:
thank you a million for writing this simple tutorial and guide on how to update to the “custom firmware”.
I really appreciate you and anyone else who contributed for taking the time to do this.
And a big thanks to Dark Alex!
just sharing:
I heard popsloader 3.80 v2 DOES NOT WORK on 4.01 m33-2
@pSp_newbie: It would require a Wifi connection to download the 4.01 official update but since I included it on the installer pack, you don’t need to connect to any wifi hotspots anymore.
@Wolverine: No problem.
@Sanondail: I’ll try to check into this one.
stylemo
i already upgrade my fw to 4.01 m33-2 through network and manually install & run addon 1.50 but every time im exiting game black screen appear and it goes off im using 8gb ms.
pls help !!!!!!!!!!!!!!
Hey StyleMo, i have 3.52 m33-4 and i want to upgrade to 4.01 m33-2. When i run the update, i get this message “some of your idstorage keys have not the correct values, probably due to a downgrader. In order to continue, press x to restore the correct values, press r to exit”. I read online that people were getting bricked when they pressed X but that was when they were upgrading from 3.52 to 3.7 (their aren’t any discussions covering 3.52 to 4.01)…so i don’t know what to do. My motherboard says IC1003 and IC6001, so i think that a T082 motherboard. I pressed R and aborted the update so i could ask you before i do anything. Id appreciate any advice you could give me. Thanks
heyz i have cfw 3.71 M33-2 will it still work?
@ShadowOps: My PSP is a TA-082 motherboard. When I was in 3.52 M33 and I tried to upgrade to 3.71 M33, I encountered that same question. I pressed X and everything worked smoothly. It was a risk that I took so I guess it’s also a risk you must take.
@shane: Of course it will. Please read the instructions very carefully.
so do you recommend upgrading to 3.71 and then to 4.01 or just go straight to 4.01
i tried to install the 3.71 firmware first and i got the same message, so this message is normal?
hey stylmo, here is what was said for someone with a similar problem
“I read that I need to use Keyclear and IDStorageManage but really am not sure what I am doing with those (dump, edit, correct the keys…). I’d appreciate any help!
people said since TA-082s don’t have the 6 or 7 keys, that it ended up bricking their PSPs if they didn’t fix the keys (besides for 5) and then create a 6 or 7.
You should always have key 6. If you’re missing key 7 and 8, do this:
Run IdStorage Manager.
Create keys 7 and 8 if missing. They’ll now exist, but they’re completely blank.
Dump the keys.
Use a PC to replace 0×0007.bin and 0×0008.bin from the dump with some good ones.
Run IDSM again and do verify/fix keys.”
Do i have to do all this before i install 4.01?
@ShadowOps: You should fix the ID storage keys.
do you have anything written on how to use idstorage manager?
@ShadowOps: no, i haven’t written anything about it. I fixed mine by pressing X when the installer asked me to. If you are really not sure about it then prepare a back-up Pandora in case of a brick. That’s how it works man.
Is there any way to uninstall the 1.50 kernel addon once it’s installed? My 4.01 M33-2 PSP is now failing to go into sleep mode properly, and any game running when I put the PSP to sleep is crashed back to the XMB…. I think it might have something to do with the 1.50 kernel, but not 100% sure… any ideas?
I got this error. The game could not be started. While I was doing step. A What shall I doo?
@Zefrem23: I haven’t experienced that yet so I’m not sure why that happens to you. I think there is no uninstall option for 1.50 kernel but you could always reinstall 4.01 M33 using pandora.
@Oliver: Have you read the complete requirements?
Okay, but I already have 4.01 firmware how do I make it to an actual custom firmware?
Hey it just saids
upacking done
please wait…
how long do i have 2 wait
Nice tutorial! Thanks!
Have a question though. If I installed this but at some point, I want to return to my 3.90m33-3, how will I do that? Do I still need the Pandora because I don’t have one. Please answer. Thanks.
Help stylemo! after upgrading my psp to 4.01m33-2 i tried to copy games iso into my psp mstick but i always get a “The Path is Too Deep” error. It never happened when i got 3.90m33-3 and older firmware.
@Griever: I’ve never heard or seen that error before. Try reformatting your Memory stick. I know it’s not a firmware issue.
i already reformatted the mstick but that error remains for 1gb and above files
Is the error due to the memstick problem? i got a fake memstick
great site! a good guide for a newbie like me! first time to install 3.40 oe-a on my 2 yrs old 2.71se-c on ta082 hehe
was not happy so decided to upgrade to 3.52 m33-4 still not contented installed 4.01 m33-2 haha thanks a lot man!
how do you update to the new custom firmware 4.01 if you already have the official firm ware 4.01
Griever, you mem stick is busted man… get a new one…

Thanks Style, it works a treat.
Hey stylemo ….. my psp slim have a 3.80 M33-5 firmware it is ok to update to 4.01 M33-2 firmware? plz help tnx..
@BUTITI: Yes. Please read the requirements.
aok…tnx stylemo
Hi! when I start this update on my PSP it says that “the game could not be started (80020148)†What should I do?
tnx alot man this guide really rullz.and the folders from the dl are easy to manage with.
Hi, this is cool. I’ve upgraded my psp with your guide.. however i wonder if i could delete now the 1.50 addon update (150.pbp and GAME4XX)?… thanks for your reply..
Nice tips man. Thanks a lot.
Uhm. I have a question.. I’m done upgrading and everything (Thanks to your guide) and, can I delete the 150.pbp file and/or the Game4xx folder??? Thanks in advance..
it dont work (game cannot be started)
stylemo… i tried updating my 3.71m33-2 to 4.01 but i got this message “The system configuration of this PSP system does not appear to be correct. The update cannot be completed.” what should i do.. any suggestions
Hi stylemo,
I have phat psp with 4.01M33-2 CFW but SKYPE icon not show ???
@goldenapol and @Jon: Yes, you may delete all the files that you used in the installation.
@john: You sure you have a PSP with custom firmware installed?
@Lanz41: Change your region settings on the Recovery Menu.
@rhythm07: I haven’t encountered that error yet. Make sure you are running on 3.71 kernel.
What should I do if my PSP doesn’t have 3.60 M33 custom firmware? My PSP is a slim one by the way! Thanks in advance.
awesome!
i did it step by step and it worked.
thanks.
My PSP doesn’t have custom firmware but it has official firmware 3.95. Can I stiil install this CF v4.01 M33-2 ? Or do I have to install other lower version of CF first? Do I need Pandora battery. Sorry for all these questions and thank you in advance.
@pspgamer
you need a pandora to downgrade to 3.90m33-3 then you can upgrade to 4.01m33-2… gudluck bro!!!
hi, I have one question, in the steps you say something like
“It will take you to the Official Sony Update screen”
and
“The Sony Updater will run”
If this is all sony stuff, then will it not become OFW? How does using sony upader turn into m33?
@aten: Because that’s how it should work. Ever since 3.71 M33, Dark Alex has been using the SCE updater to do the update for him.
Yes, thanks, I did this update on my slim 3.71M33-2 and it worked like a charm! However, much to my disappointment, PS1 games no longer worked, so I had to google a lot and found something called “popsloader”, configured it and FINALLY they worked again.
Thanks for doing this stylemo, you’re the best.
I’m getting the black screen then it says “Unpacking… done.” “Please wait…” And it just sits there. I’m running 3.52 M33-4 Any ideas?
“I’m getting the black screen then it says “Unpacking… done.†“Please wait…†And it just sits there. I’m running 3.52 M33-4 Any ideas?”
Same for me :S
What happened with yours man?
Nothing.. lol It just sits there. I even just tried going to 3.90 first, but even that pack is doing the same thing.
ergh…
I was afraid, waited an hour or 2, and nothing… then restarted and then tried again…. nothing…
:\
Well i found our problem, i’ll show you how to solve it
Pressing R button while starting PSP
Then “Configuration> “Game folder homebrew” > choose “currently (your installed firmware version here)”
It worked for me!
haha yep just found the same answer on a different forum was coming to put the same thing up. cheers man
Heheh i found it by myself who would say..
cheers!!
hay ive successfully installed the firmware and the m33 but when i tried my games they all doesnt work anymore. an error keeps popping up saying that game cannot be started, help please? does not installing the 1.50 kernel has to do anything with it?
Can i delete ALL the files that i used for this installation? BTW, thanks for the tutorial, it worked!
I have a mint green PSP from Japan, OFW 4.01. I already brought it to different modifying shops, but I think the problem is it has the new motherboard. Will this program work on that?
i have firmware 3.95 normal how do i turn it into custom. please help email me at alphadragon@hotmail.co.uk
stylemo i have installed as above but when i run games it saysthe game could not be started 80020321
any help
found the solution omg
i had the same problem getting game could not start 80020321 you need a umd in the drive and the games will work ok
hope this helps
@iain: I’m glad you finally found the solution to your problem. Some games need a UMD in the drive to run. But some doesn’t require any, you just have to adjust the settings to the right driver.
thanks for all your work on this, stylemo. your guides are the easiest to follow i have seen!
i’m on 2.60 on a phat psp (old school, i know) and have been using fanjita’s eboot loader to run homebrew forever. i finally have a game i think is worth updating for so i’m going to dive in.
here is what I plan to do based on my reading here and elsewhere. Please comment on if I am missing anything or if there are better ways to do certain parts.
1. I will first want to upgrade from 2.60 ofw to 2.80 ofw in order to run the downgrader i found on psp-hacks (if you know of a great downgrader, let me know).
2. I will then downgrade to 1.50.
3. I will then install 352-m33-4 as your older installer can go from 1.5 to 3.52
4. From 3.52, I can then install 4.01 M33-2 with your installer (along with the 1.50 add-on).
5. I should be good to go, and have the ability to create a magic mem stick and pandora battery.
or, at step 4, I could go ahead and create the magic stick and pandora battery from 3.52 using DC v7 and install 4.01 m33-2 from there. Not sure what is the better option.
So, what do you think? Am I missing something? thanks for your time!
stylemo
how do you adjust the driver settings?
thanks
@smalltimore: You are absolutely right about the steps you have written. You can create Pandora while you’re in 1.50 so that you could get straight to 4.01 M33-2. But if you don’t have a spare battery to create into Pandora, you could just follow the steps you have written. Both works.
@iain: You can access the driver menu via recovery mode or by simply pressing home to bring out the VSH menu. You can then toggle the driver settings.
thanks, stylemo!
what would be the best way to create pandora straight from 1.5? i like this approach as then i will have the tool in case the update to 4.01 goes fubar. can i use your installer to straight from 1.5 to 4.01, or do i need to get to 3.52 first?
cheers stylemo
got it sorted now
your the man!!!!!!!
wow, thanks again! i’m on 4.01 m33-2 all the way from lowly 2.6! nice. all of my brew is working (unh, PSPSeq) AND I can play God of War. w00ts all around.
gud day stylemo man i need your help i update the version of my psp fat to 3.90 m33 and after i done it i could not play or install anything in my memory stick i also tried to install kernel 1.50 but there is always an error message appearing (error 80020148) hope for your response. TY!
Thx for the great guide. It was the easiest to follow from all that I’d found. I do have a question though. Can I delete the GAME4XX and 150.PBP file from my memory stick or should I just leave it there? Thanks again.
I have 3.71 M33 and I try to install the update but my psp just turns off and nothing comes up, I tried it about 5 times while it was plugged in
thanks for all help in advance
never mind, I figured out the problem, my firmware version was set to 1.5 in the recovery menu
need some help again stylemo
cant play homebreww m8y
keep gatting the game could not be started 80010002
any help m8?
i put them in the 4.xx folder and same message so i created a GAME150 folde and put em in there and same
@iain: You must have a UMD on your drive. But you could also do it without UMD. Simply access the VSH menu and change the UMD driver settings.
bro. agited ka man ti instructions nu kasatnu ag dload ti games ti psp ken anya ti papanan nga sites. please nagngina ti games d2y. hehehehe cool sites dude.
Thanx for the tutorial an all,I managed to put the cfw on my PSP but when I try to run the update it says it can’t be played on this psp….And please don’t ask me if I did everything right,I’m not that stupid,I know how to copy and paste a folder….so if anyone has any solution I would highly appreciate it(I don’t have any other cfw instaled and my psp version is 3.95,I bought it 2 days ago…)
@Galatea: you need to have a previous installation on your PSP. 3.95 doesn’t make it.

I have a psp with firmware 3.95 GEN. How can I upgrade to 4.01 M33-2?
@tomorrow
simply follow the tutorial
Thanks a lot….great guide!
I’m also running 3.95 GEN, but want to cross over to Custom firm-ware. These requirements say that I have to already posses an earlier version of custom-ware before I can proceed; true? Can I really just proceed anyway?
Hey guys,
Would a 2 gig memory stick be ok to use.
Thanks in advance from alex
Thanks lots. Super easy with these instructions
Jeez. after many tries and head bonking i finally got it to work. really great guide. im enjoying every moment of my psp now.
excuse me, since you already said we can, how do you revert back from 4.01 m33-2 to the previous 3.90 m33-3? because i didn’t upgrade to 4.01 m33 first before i installed 4.01 m33-2, they website i went to didn’t even say that was necessary. i don’t know what to do. can you please email me? bluesonnet21@yahoo.com.
Is there a way to get this custom firmware onto a PSP Slim running Sony’s 4.01 firmware? I read that since my firmware is ABOVE 3.51, I can’t downgrade it. Please email me at wrxdrifter2005@gmail.com
I could not install the 1.50 kernel add-on for fat psp.It is showing that incorrect or in existing 150.pbp at root.please help me at saddiabhishek@yahoo.co.in
Hi, where still waiting for Dark Alex (god bless him) to finish the latest update so I have an advanced topic request
Could you please write a topic on how to play ps1 games on the psp using the unfinished update, ofcourse when its complete though
And god bless you
Hi, I asked a question in the forum on “How to Install 3.52 M33-4 on Your PSP” but it seems to be dead in there, So sry for asking it in here.
I got a psp phat with 2.71 SE-C firmware, and want to update it to 3.52 M33-4 and then to 4.01 M33-2.
Since I got 2.71 SE-C I guess I can skip to step 2. Am i right ?
It says that I should copy the M33CREATOR folder to my “ms0:/PSP/GAME150″ (for SE/OE Firmwares)
my only problem is that there is no GAME150 folder, I have a folder called GAME thou
can I copy the files there and go on from there ?
help appreciated.
Thx!
@Rickard: Yes you can skip to step 2. Create a GAME150 folder if you don’t have one.
Ok, went for it before you had time to answer :/
Just got my psp a few days ago, so im 100 percent noob, but everything worked like a charm.
Thx a million for the great guide!
piz!
u r a legend worked perfectly, keep up the good work
if upgrade my psp fat to CFW 4.01m33 can i change it back to 3.71m33-2 again?
@Jawo241: Yes sir.
Can this be done on OFW?
@dethmoose669: Yes, but you have to install custom firmware on it first.
I also can’t finish step C, same problem with abhishek, incorrect or inexisting 150.pbh at root
nice guide btw, everything worked out fine except step C
@Jake: If that’s a slim PSP you are installing it won’t work. 1.50 Kernel Add ons are for Phat PSPs only.
mine is the phat one… any suggestions? When you said the root directory, you mean the MPRoot right?
@Jake: I meant at the root of your memory stick drive. For example if your memory stick drive appears on Drive F:\, the 1.50.PBP file must be located here: F:\150.PBP. Get it?
yes thanks, I got it lol. It’s my first time so… thanks again:P
I have installed 4.01 firmware update on my PSP slim but how can i revert it into 3.90 again? please help
@anton: Can you be more specific? Are you talking about custom firmware here? Please give me some details about your PSP. I might be able to help you.
Thanks for your reply. yes, I’m talking about the Custom firmware. i have a silver slim psp & i have updated it to cfw 3.90 a week ago it works fine & the ctf themes is working smoothly but when i updated it to 4.01 m33-2 it cannot recognized the ctf themes anymore. can u help me to put it back into cfw 3.90 again. please
I didn’t notice this before but now that I am playing Star Ocean: First Departure, Wild ARMs XF and even the first Valhalla Knights game, my PSP hangs. I’m using 4.01 m33-2 and it wasn’t hanging before (even when exiting the game via the HOME button) but started hanging when I played WA XF and installed cwcheat. I disabled the plugins but it still hangs when I’m playing SO: FD. My question is that will this be fixed when I upgrade to 5.01 m33-3 or do I have to reformat my MS? Thanks in advance
Hi, nice guides you have here. I’m kinda stuck here and i don’t know what to do, i just updated to 3.52 M33-4 and am currently trying to update to 4.01 M33 following this guide so i can continue to update to 5.0 M33, iv’e done exactly as in the guide (i even tryed to fomat my memorystick before updating) but it wont work for me to update to 4.01 M33. I put the “update” map in “psp/game” then start the update, there the black screen comes up and it says “Unpacking… done.” and then “Please wait…” then nothing more, i had it wait there for 20 minutes without anything else happening, and iv’e tryed to update like 15 times now and i always get stuck at the same place, so if anyone has any idead on how to make it work, please feel free to tell me, or email me at “challebell@hotmail.com”
Never mind, i read through all the comments and found the answer to my question!!
I love your tutorials and easy to access files. I searched all over and could not find a decen tutorial till I stumbled upon your. Keep up the GREAT work!
it started sce updater…..the it says that the system configuration of this psp system does not appear to be correct…
I am currently running on 3.90 M33-3 and wanting to upgrade to 5.00 M33-3. I saw that in your requirement is minimum 4.01 M33-2 therefore I have come here to download the update. The link for the 4.01 M33-2 installer pack download is not working. Can you please help me, or is there an alternative way to upgrade to 5.00 M33-3? Thank You
thats totaly awsome thankyou!
nvm it sucks couse it took like 40mins then when it was done it wouldnt respond and it almost fried my computer this sucks!!!!!!!!!!!!
I followed the steps, but, for some reason during step A, when I put the firmware on my PSP, I go to GAME>MEMORY STICK, and find “Corrupted Data” there. I don’t know what I am doing wrong.
DUDE YOU ARE EFFIN AMAZING!!! These installers are awesome! Your step by step instructions make it so easy and thankfully everything worked just as you said it should! Cheers mate!
Thanks. I’m glad it worked for you.
I need help, I don’t know if its working. It says:
“unpacking…done.
please wait…”
And its been like this for like 10 minutes, is this normal? how long does this take to please wait?
I have taken a PSP slim which contains version 4.01 …

i have a psp with a regular system software 3.93. no custom firmware. my question is how do i get custom firmware on it. do i have to have a pandora battery and a special memory stick? or can i just install 4.01 m33?
I mean i think it should work if i download and istall the 4.01 M33-2 installer pack, as you are saying in this blog. but in you Requirements you say that i have to have a custom firmware alredy. but how do i get that in the first place.i realy want some help with this. my email is sutkorv@hotmail.com.
@viktor: You need to borrow your friend’s Pandora battery and just use Despertar del Cementerio v8.
wat does XMB mean?
XMB means – Cross media bar. It’s the navigation system you see on your PSP.
? i don´t see how that would help me. the only thing i want is to get a cfw 4.01 or something like that so i can play some games on it. i don´t have a friend with pandora, i don´t know what Despertar del Cementerio v8 means
can you get 5.00 after?
how long the original battery of psp phat last. for gaming

Hi, I have a new PSP Slim 2006,having the firmware of 4.01. However, I was told that this PSP is not able to be modified. Is this true? Is there any way to modify this PSP?
this walk through really helped me out and worked perfectly! thanks!
doesnot work for me.. my PSP (slim) said that installation failed for step 1. contact technical support, etc.. now my psp is not working/does not turn on. i tried to upgrade my 3.71 m33-2 to this firmware. pls help. dark_sniper_15@yahoo.com tnx
When i run the program it sais unpacking then please wait but it never goes any farther. i have a fat psp with fw 3.52 M33-4. please help
That’s a common problem. Try using anothr memory stick. Your memory stick might be fake or corrupted.
if i had a brand new psp, can i easily upgrade/downgrade it like what you do?
Sure if you’ve got the right tools, you can. What type of PSP are you gonna buy anyway?
Hi
I followed the instructions of Step A but it stopped working after that. I feel I did brick it. What is the solution??
would this update work for 3.71 M33-4? I know it says “At least 3.52 M33-4″ but I have to know for sure. Also great tutorials on updating CFWs I have been following them for a couple days now!
ok nvm I updated my psp phat to 3.90 M33 then updated to 4.01 M33-2. Thank you so much for the tutorials! You are so awesome!!!! BTW is MP_ROOT the root of my mem stick?
Once again I know where my root of my mem stick is

Hi, i only have 4.01 which comes from the box. as what you mention in the requirments
>>A Fat PSP or Slim PSP already installed with a custom firmware. At least 3.52 M33-4 custom firmware must be installed on your Fat PSP and 3.60 M33 for the slim.<<<<<
do i have to go first with 3.60 m33 before i can proceed with this?
whats kernal add-on and wheres the root directory of my memory stick?
my psp went to the black screen but no text appeared, what do i do? i met the requierments list at the top of the page
FK!!! my psp is hacked and i had 3.90 m33-4. But i downloaded wrong firmware from google and now i suddenly have OFW 4.01?!?!?! How can i make it back so i can play downloaded games again??? PLS HELP!!! I have PSP phat
Patrick1996: well you have to get a padora battery to downgrade your psp or you can make it by searching google or searching youtube
it doesn’t fucking workss
It works great and the instructions were simple. Only an idiot wouldn’t be able to get this to work.
Thank so much for this AWESOME program!
Configure your kernel to be running on 3 3.52 if you have 3.52 M33-4. How do we do this? Easy, turn off your PSP and then turn it on again while holding the R button. You will see the recovery menu so go to Configuration > Game Folder Homebrew and set your respective Kernel.
That did the trick for me, as it hanged to “Please wait..”.
Alright,can I use the steps above on a JAPAN psp-2000 slim??
