How to Upgrade to 3.71 M33-4
Dark Alex has released days ago the 4th update for the 3.71 M33. This one’s easy to install but for newbies out there, I’ll still make you a very simple a guide even your grandma can follow. But what’s new on the 3.71 M33-4? Here’s the changelog according to Dark Alex:
- Bugfix: Multidisc psx games bought in the psn store would not work due to the format being different and M33 treating them as decrypted games.
- Added support for decrypted multidisc psx games created with popstation_md (supplied with this release)
So let’s go on now with the installation. The process is very easy but like I always tell you boys and girls out there, it’s better to read the instructions very carefully.
Requirements
This is the essential part of this guide. If you find that you don’t meet the requirements, better not continue the process because it won’t work or you’ll might end up bricking your precious PSP.
- PSP with 3.71 M33, 3.71 M33-2 or 3.71 M33-3 custom firmware. For newbies, you can see the version of your PSP on your XMB by going to System Settings > System Information. And again, for newbies, this doesn’t work with Sony’s official Firmware
- USB Cable for transferring files from your PC to your PSP
Instructions
- Download the M33 Update 4 file here and save it to your computer. You can get it on Dark Alex’s website.
- Once downloaded, extract the contents of the file to anywhere on your computer. Copy the UPDATE folder to your memory stick in the x:/PSP/GAME where x is the drive of your PSP.
- Go to the XMB menu, scroll to Games> Memory Stick and run the M33 Update-4 program. You will be asked to press X to start the update. Do so. The program will exit automatically and restart your PSP. You now have a PSP 3.71 M33-4 PSP. Grab a Coke or a Pepsi. Eat spaghetti and celebrate.
Well that’s it. I hope you guys like this easy guide.

You may not be using this blog much now, but I just wanted to thank you for the guide - I’ve been looking all over the net for a specific guide on upgrading from 3.03 OEB to the current 3.71 M33-4, but I couldn’t really get anything specific…
Thanks again for your great work, and look forward to more stuff from you - i’ve booked marked your page!

Hey Guys,
Total newbie here but I have been through heaps of sites… I still don’t find it very clear how I need to start out with the requirements.
Quote “PSP with 3.71 M33, 3.71 M33-2 or 3.71 M33-3 custom firmware” so I click on one of those links and then it says for the requirements on those pages to have 3.71 M33-4 installed…
Hmm can someone please explain? Cheers

Help have problem when i download the file update 3.71 m33-4 on dark alex site.. when i unzip the file there’s no update folder… it only has the popstation_md folder and a readme.txt file…;(
February 4th, 2008 at 11:47 am
@khayzie: Maybe you should try again. I downloaded the file on Dax’s website and the UPDATE folder is there…
February 11th, 2008 at 4:46 pm

dark alex’s m33update4 link is a deadlink… any alternatives??
March 9th, 2008 at 2:28 am
@marlow: dark alex’s links are never dead my friend. try to check your net connection….maybe your isp has not been giving you what you are paying for lately.

hi everyone,im planning to put the cfw 3.90 m33, i have the 3.71 m33-2 my question is, can i upgrade directly to 3.9 m33 without worrying about the kernel, or i need to put kernel in every upgrade i make?? is there a risk of bricking the psp, sorry for these questions but im tottaly noob to this.
March 25th, 2008 at 10:54 pm
i encountered the same problem as che che…it appears to be a corrupted file… T.T
April 3rd, 2008 at 3:21 pm
same here am wondering if i can upgrade my slim psp v3.71m33-2 to v3.90m33 directly without upgrading to v3.71m33-4 first…
April 3rd, 2008 at 3:39 pm
To all: To those who have a PSP - whether Phat or Slim that has 3.52 M33-4 or higher custom firmware installed, you could directly go the 3.90 M33 guide and no need to follow this guide.
July 27th, 2008 at 3:53 am
I tried this upgrade. When I run the upgrade, the screen goes blank after sometime. Nothing happens after that. When I restart the PSP, it’s still at older version (3.71 M33).
What do I need to do different?
