How to Update to 3.80 M33-2 Custom Firmware
Just minutes ago, I wrote the installation guide for 3.80 M33 Custom Firmware. now I’m writing a guide on how to update 3.80 M33 to 3.80 M33-2. So why update? Is there a bug or something? Actually there is. This update is necessary for plugins and kernel homebrew reporting psp cpu speed. Also 80 by 80 PSX icons will not be replaced by a Dracula icon anymore.
So let’s get on with the guide. But first, a few reminders, I will not be held responsible if something happens to your PSP. I’ve updated mine using this guide I made and was successful.
The Requirements
- You will need a PSP installed with 3.80 M33 custom firmware. If you don’t have it yet, then follow this easy 3.80 M33 installation guide I wrote earlier.
- 75% Battery or more. Why? So you don’t brick your PSP when it shuts off in the middle of the update because you forgot to charge the battery.
- A USB Cable to connect your PSP to your computer.
Please make sure you pass all the requirements before getting on with the installation.
The Installation Guide
- Download the 3.80 M33-2 update files.
- Extract it anywhere on your computer.
- Connect your PSP to your computer via USB cable and copy the UPDATE folder from the file you’ve extracted to your PSP in this drive: ms0:/PSP/GAME/
- Disconnect your PSP from your computer then got the XMB menu. Scroll to GAME > Memory Stick and run the M33-2 Update Program. Follow the onscreen instructions.
- Enjoy your updated PSP!
If you love homebrew applications then you might consider installing the 1.50 Kernel add-on for 3.80 M33-2. This only works for the Phas PSP.

How to upgrade from 3.80 to 3.80 M33?
3.80 M33-4 is out…..
Can anyone tell me, how to update from 3.80 to 3.80 M33.
Coz, I have mistakenly network-update to 3.80 official firmware from Sony. So, I need the 3.80 M33 now to be able to run my memorystick games.
Could you please give me exactly which steps to take, I will do it exactly to get it done.
Thanks for you help in advanced
@Sonylla
You need to downgrade your psp first using downgrader and pandora’s battery. then you can apply custom firmware.
Try http://www.psp-hacks.com/ or http://www.psp-vault.com/ for guides on how to downgrade.
But I’m not sure if your still able to downgrade from 3.80 official.
Best of luck to you.
OK i have installed 3.80m33 with no problems so far, but now when i am trying to update to 3.80m33-2 or higher i cant get it to work.
i followed your instructions and placed the update folder in x:/psp/game just like i did with the 3.80 update but then when i try to access the update through the XMB it says “there are no games” even though i have placed the UPDATE folder in the GAMES folder and the GAME150 and i even made a GAME380 folder and placed it there.
i know for a fact that i installed 3.80 correctly because when i go to system info it says “3.80 m33″ and also when i try to use network update it says it found a new update and when i try to download it says “download failed”
can anyone please help me? i really want to be able to run homebrew, otherwise i would just use official firmware.
thanks in advance for any help.
@Jethro: Haven’t encountered that problem yet. Please check your Kernel settings in the recovery menu. It should be set to 3.80. And skip this guide because 3.80 M33-4 is already out. Follow my guide on that. http://www.stylemo.com/2008/01/17/how-to-update-to-380-m33-4-custom-firmware/
I’m having exactly the same problem as Jethro.. any advise?
Even putting the 3.80 M33-5 Update in x:PSP/Game/ folder also doesn’t have the update file show up in the xmb game memory stick. Network update doesn’t work as i always get Download Failed error when tried to download it. So what now?
can i play games through memory card after installing this update?
@Hassaanq: Yes.
my psp slim and light had a 3.71 M33-2 firmware, for a while it reads and plays memory card games but today it does not work that way.what should I do?pls help me
