How to Upgrade to 3.71 M33-3
It’s been days since Dark Alex has released something for the PSP homebrew community but with his return he brings you the third update for his 3.71 M33 custom firmware. If you’re wondering what’s new on this update, well here they are exactly according to DAX:
- Fixed a bug in access to flash by usb.
- HEN core: kernel prx’s with syscall exports work again.
- PSP Slim: programmers can set the size of user memory to 52 MB by using a sfo flag.
Check sample in sdk for usage. - March33 NO-UMD driver:
* Fixed a bug that could hang the psp when exiting with home.
* Fixed compatibility issue with Castlevania Dracula X Chronicles, and maybe more games. - Vshmenu: it wasn’t displaying properly with psp slim TV-OUT due to the change of resolution. Fixed.
Below are the easy steps on how to do the update on your PSP.
Requirements
- A PSP with 3.71 M33-1 or 3.71 m33-2 Custom Firmware
- USB Cable for PSP to PC connection
Instructions
- Download the files here.
- Extract the contents of the file. Grab the UPDATE folder and copy it into your memory stick to the directory PSP/GAME/.
- On the XMB menu go to Games > Memory Stick and run the update. 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 M33-3 PSP
About the popsloader, I haven’t been able to try it yet. Actually I haven’t been using it for quite sometime. I really dig the new games around. But I’ll be glad to write something about it if a lot of people asked. Thank you all.
UPDATE: You can now skip this guide and go directly to the 3.71 M33-4 update. I wrote a guide on how to add the 1.50 Kernel Add-on for 3.71 M33. Please check it out if you need it.

hey This update sucks. the 3.52 M33-4 has much better advantages than this peace of shitty firmware. it doesnt even allow you to execute the umd dumper. feature. also pandora doesn’t work on it. so to those of you who already upgraded to this firmware two words for you “you’re screwed”

Thank you stylemo; that worked perfectly. To recap for others:
1. Download 1.50 add-on from link just above
2. Download 150.PBP from here –> http://72.29.74.204/~exophase/external/150.PBP
3. Copy 150.PBP to the root of the memory card (i.e. x:\)
4. Copy UPDATE folder from the 1.50 add-on link above into \PSP\GAME
5. Run the UPDATE program from the game menu
6. It will auto restart when finished
Thanks again to stylemo, and many others for their hard work!

I’m sorry that wasn’t in the guide but it’s fairly easy to install the 1.50 add-on. Please check out this page and download the 1.5 add-on file. You’ll be needing that file and the 1.50.PBP which you can also get from the site I gave you.
I’ve been very busy this week but if I’ve got some spare time, I’ll be writing another guide about installing the 1.50 add-on. Thanks peeper.

Stylemo, thank you for writing the guides, btw. I should have mentioned that in my previous note.
stylemo said “That’s because you haven’t installed the 1.50 add-on yet.”
Wow, I had no idea. Was that in the guide somewhere and I just missed it?

@peeper: That’s because you haven’t installed the 1.50 add-on yet.

Bummer, followed your processes “exactly” and Homebrew apps/games no longer work.
1. Started with PSP-100 [fat] 3.02OE-A
2. Upgraded to 3.52 M33-4
3. Upgraded to 3.71 M33-1
4. Upgraded to 3.71 M33-3
Set “game folder homebrew” to 3.71 in recovery mode (rt shoulder + power on).
Homebrew games in the GAME150 folder no longer work giving the “80020148″ error.
