How to Install 3.52 M33-4 on Your PSP

As I promised Fat Of The Land and a lot more other people around the net, I’ll be writing a guide on the installation of 3.52 M33-4 custom firmware for the PSP. If you’re wondering what in the world 3.52 M33-4 is, it’s a custom firmware built by russian hackers that enables you to play homebrew and also enjoy the features of the official 3.52 sony firmware.

Before we begin with the process, here are a few simple things to do first.

Check your existing PSP Firmware.

On your XMB (Cross Media Bar), go to Settings > System Settings > System Information. Press circle or x (it depends on what PSP version you have) to view your existing firmware. If you have a 1.5 or any custom OE/SE firmware, you are in luck. You can proceed to the next step, otherwise, you must downgrade your PSP first. I suggest you use Pandora’s battery for the downgrade.

Obtain a USB Cable

If you don’t know what a USB cable is, I assure you won’t be successful with the installation. A USB cable is a connectivity tool between your PC/Mac and PSP.

Download the 3.52 M33-4 Installer Package

I packed all the files into a RAR file so you won’t have any trouble locating the files around the net. After downloading the file, unpack it using WinRAR. I’ve separated each step into separate folders so everything will be organized.

Download the 3.52 M33-4 installer pack.

Check Your Battery

I suggest you must have more than 75% battery to avoid bricking. And also plugin the adaptor.

If you have correctly followed the few simple steps above, then we are ready to go on to the installation process.

Warning: I have succesedfully installed 3.52 M33 on 3 PSPs already but there is a slight chance of bricking your PSP, only if you won’t follow the instructions step by step. Don’t worry if you brick your PSP, you can always use Pandora’s battery.

3.52 M33-4 Installation Procedures

  1. If you have are running on an OE or SE custom firmware, SKIP this step and proceed to STEP 2. Connect your PSP to your computer. Open the STEP 1 folder and copy kxploitpatcher and kxploitpatcher% folders to ms0:/PSP/GAME/. Disconnect your PSP from your computer and then on the XMB go to GAME > Memory Stick > KXploit Permanent Patcher. Run it. Once done, delete the kxploitpatcher and kxploitpatcher% folder from your ms0:/PSP/GAME/ folder. Proceed to next step.
  2. Connect your PSP to your computer. Open STEP 2 folder then copy the M33CREATOR folder to your “ms0:/PSP/GAME” (for 1.50 Firmwares) or “ms0:/PSP/GAME150″ (for SE/OE Firmwares). Disconnect your PSP from your computer then on the XMB menu go to GAMES > Memory Stick and execute 3.52 M33 CREATOR. For noobs, the screen will normally go black so don’t panic. Once the process is finished it will automatically go back to the XMB.On your XMB, go again to GAMES > Memory Stick on your PSP, and execute 3.52 M33UPDATE. You’ll have to press X at your own risk to agree to the installation. Don’t you turn off your PSP until the process is complete or you’ll end up bricking it. When finished, you’ll have to press X again and reboot your PSP manually. Reboot by turning of your PSP and then turning it on again.You’ll then have a 3.52 M33 PSP. You can now delete the M33CREATOR folder form your “ms0:/PSP/GAME” folder on your PSP.
  3. Open STEP 3 folder and then copy M33Update4 folder to mso:/PSP/GAME150. On your XMB menu go to GAMES > Memory Stick then execute the update. After the update you will be back on the XMB and you now have 3.52 M33-4 PSP. Delete the M33Update4 folder from mso:/PSP/GAME150. From the STEP 3 folder, copy the seplugins folder to the root of your memory stick.
  4. Turn off your PSP then turn it on again while pressing the R button. This will take you to the recovery menu. Go to Plugins and enable popsloader by pressing x. After enabling it, go to back and then exit.
  5. Enjoy your PSP 3.52 M33-4!

You have PSP 3.52 M33-4, now what? Get those cool homebrew apps! You can either stick with this firmware for some time or upgrade it to 3.71 M33. I had mine installed with 3.71 M33 already and I say it’s really cool. There are new features like changing themes from XMB and a new kind of Video search.

Special credits go to Dark_Alex (he is the M33 team) M33 team, the Russian Hackers who created this neat piece of software. Please do check out his website for the latest updates.

UPDATE: After installing this firmware, you’ll probably be wanting to install 3.71 M33. So here’s the 4 Easy steps on installing 3.71 M33 on your PSP.

    You know, while I was waiting for the new file to be uploaded I just did it myself. And you don’t need to install ALL the version to get up to M33-4, you only need to install 3.52 M33 and then upgrade to M33-4…so I don’t know why you posted all the extra unnecessary steps, stylemo.

    Just one thing still missing on this Custom Firmware is LocationFree Player.
    The icon is there but nothing happens when trying to open.
    So unfortunately I now need to go back to 3.03OE to use it.
    I’ll have to email the creator of this CF to get this fixed.

    Everything else looks good though.

    Why are you trying to upgrade to M33-2? Are you not going all the way to M33-4? If you are going to M33-4 just install the M33-4 update…not the M33-2 and M33-3 update…you’re just wasting your time…but your choice.

  17. 17
    stylemo

    RIGZ:

    You need to have a homebrew enabled PSP which means you need a PSP with a 1.5 firmware or any of the custom firmwares. I think you need to downgrade your PSP first before trying this one. Please search Google about PSP homebrew first before trying anything else. Thanks.

    Hey,

    I got 3.03 Oe-c on my psp (thats what my psp tells me)
    But when i go on my psp i see a map iso and a map psp.

    ok hold on i just set the game map to 1.50 is that correct ?? or do i need it to be 3.03 ??

  30. 30
    stylemo

    Yannick: Check if you are running 1.50 kernel on your GAME folder by going to the recovery menu. Now how do we do that? First, shutdown your PSP and then turn it on again while pressing R button. It will then take you to the recovery menu. Got to the configuration > Game Folder Homebrew and check if it’s 3.03. If it’s not, change it to 3.03 then exit the recovery menu.

    After that begin with Step 2.

  31. 31
    Yannick

    Thank you :) its 3.03 right now so i need to charge my battery :)

  32. 32

    Yannick

    error is (80020148)

  34. 34
    stylemo

    If your GAME folder is running on 3.03 then create a folder named GAME150 then there you put the M33Creator.

    Hope that helps.

    dont worry about it i have a ta-082 and it works awesomely
    and i only got into the homebrew scene a few days ago!

    oh and just some info, once you downgrade a ta-082 to 1.50 it acts like any other psp so you can run every home brew app easily

    p.s corrupted data is the stuff that makes homebrew work so once you do the hack you can go into recovery mode and hide all the corrupt icons.

On your XMB menu go to GAMES > Memory Stick then execute the update. After the update you will be back on the XMB and you now have 3.52 M33-4 PSP. Delete the M33Update4 folder from mso:/PSP/GAME150. From the STEP 5 folder, copy the seplugins folder to the root of your memory stick.”
    there is no GAME150 folder so i decided to make one. When i go to games nothing shows…should i copy the M33Update4 folder to mso:/PSP/GAME and try and run the update?

    You need a UMD in order to play most of the games but you can tinker with the UMD ISO MODE settings by pressing the HOME button while on XMB to display the VSH menu.

    To all people having trouble with their ISOs, try reformattng your memory stick or resetting the device. Most of your questions are answered in the comments you just have to scroll through it. Thanks.

    Hi.

    I got a question. I am on 3.40 OEA. I did all the instructions as listed. Looks fine but at the end of it all, the firmware shown is still the same.

    Is it suppose to be like that?

  107. 107
    Max

    When I run the creator I am getting
    Loading 1.50 firmware… OK
    Writing 1.50 firmware… OK
    Loading 3.52 firmware… OK
    Writing 3.52 firmware…
    and it stays like that for 20 minutes? what should i do? HEEEEEEEEELP!!!!!
    Does this mean I’m doomed already for BRICK if I turn off my PSP? WHAT TO DO????

    hey Max, that’s not supposed to happen. What was your last firmware you upgraded from. if ever you bricked your PSP, you can always use pandora’s battery to revive your device.

    Hi! I came out for 2 hours and I came back now and I found out that proccess has finished with success. Woah!
    Now I have to do STEP 3…I hope everything will be OK.
    I had Dark Alex’s 3.10 OE-A and I fresh formated 1 GB MS Sony Pro Duo before this. maybe that caused a delay. Anyways, thank you stvlemo for trying to help.

    Max

    everything went Ok, I just want to ask a question:
    Do I really need POPSLOADER to play PSX games. Because I had only to upgrade to 3.10 OE-A and I would put PSX game’s EBOOTS in ISO folder where I put PSP games and everything would work just fine. So do I really need popsloader now?

    Hi. I don’t know if this has ANYTHING to do with this, but i have a problem. I updated my PSP successfully to 3.51 M33 with my 1GB Memory Stick, but after i updated, my memory stick was still in and the PSP couldn’t read it. The memory stick light just kept blinking nonstop. I took it out and placed it in again and again. It still couldn’t read it. I’m wondering if you know what the problem is ’cause I’m planning on getting a new memory stick. A 4GB. Plz help.

    I cannot get the download to work on Mediafire, the download fails everytime it gets to 3.59MB??

    Is this unique or have other experienced the same thing??

    I’ve been out of the game for a while and still got 3.03OE-C!!

    Time for a change!

    @BassGX - You have a corrupt memory stick. Time to get a new one.

    @Ant - the file is there. Retry a few times. Mediafire is still buggy.

    I’m having the same problem as Max on Step 2 and I’m not sure why… it says:

    3.52 M33 FIRMWARE CREATOR

    Loading 1.50 firmware… OK.
    Writing 1.50 firmware… OK.
    Loading 3.52 firmware… OK.
    Writing 3.52 firmware… *waiting for 20 minutes*

    I’ve upgraded successfully to 3.52 M33 before from an 3.40 OE-A. I don’t know why its not working for this 1.5 downgraded PSP. :(

    @Jason: Did the screen turn black? if so, just press the directional buttons. The backlight just might have turned off. Press any of the directional buttons to turn on the backlight again.

    “”" @Jason: Did the screen turn black? if so, just press the directional buttons. The backlight just might have turned off. Press any of the directional buttons to turn on the backlight again. “”"

    Hi - I’m having the same issue as Jason and a few others on here as follows:

    Loading 1.50 firmware … OK
    Writing 1.50 firmware … OK
    Loading 3.52 firmware … OK
    Writing 3.52 firmware …

    It’s been 30 minutes. According to Jason after a few hours it processed.

    Like you said, just push the directional pad and it will refresh itself… however still not processed.

    I’ve always had the original 1.50 version since I owned this PSP. I have a few custom emulators downloaded on my memory stick and some MP3 files, but that’s it.

    I wonder what my issue is? I’ll let it sit for awhile then come back and see what happens.

    If anyone can provide some insight, that would be greatly appreciated.

    Thanks!

    Josh: You just have to wait, mine took lore than 20mins, im not sure if you can turn your PSP off but after than process when I try to update my PSP the gameboot showed up but then I waited for more than an hour and still nothing happens then I took the risk and turn my PSP off and boot it again. And guess what it did not brick and I did that twice before I finally successfully updated my PSP
