How to Add 1.50 Kernel Add-on to 3.71 M33 Custom Firmware
I know this post is a little bit late. It’s more than late, probably, but there are still a lot of guys asking me to make this tutorial. I’ve been very busy the past few days that’s why I haven’t been updating too much. But because you guys asked for it, I’ll give it to you. Well, here you go. This is the ultimate guide on how to add the 1.50 kernel add-on for your 3.71 M33 or higher.
REQUIREMENTS
Be sure you meet all the requirements before attempting to do this process.
- A PSP Fat (No it does not work with a SLIM) with 3.71 M33, 3.71 M33-2 or 3.71 M33-3
- Make sure you have the GAME folder configured to 3.71 or the program won’t start. How? Enter the recovery mode and go to Configuration -> Game folder homebrew. It should read Currently 3.71 Kernel
- A USB that will connect your PSP to your PC
- A keen and watchful eye and a brain that will help you follow and read the instructions very carefully
If you meet all those requirements then you are good to go.
INSTALLATION GUIDE
- Get the 1.50 Kernel Addon on the QJ download site. Once on the page, scroll down a bit, and you’ll see an orange button that is labeled “Download”. Click that button and save the file to your computer.
- Extract the file and you will see and UPDATE folder. Connect your Fat PSP to your PC with a USB cable. Copy and paste the UPDATE folder from your computer to your PSP ms0://PSP/GAME/
- Download the 1.50 Firmware here. Connect your PSP to your PC and copy the 150.PBP you’ve just downloaded into the ROOT of the memory stick.
- Disconnect your Fat PSP and on the XMB menu, go to GAME > MEMORY STICK and you’ll find the 1.50-2 update. Run the update and press X to agree with the installation. After the installation, the program will auto-exit.

I don’t think it was really necessary to make a tutorial for this lol, it was pretty straightforward when you explained what happened before.
this is nice but its better if u have de UPMS ( Ultimate Pandora Memory Stick ) cso file to make your stick multi bootable and the you can use the option (from HELLCAT) of rebooting to the full 1.50 firmware while u use those 1.50 apps and games and all it takes is to rebbot your psp to go back to your day to day firmware (3.40 OEA,3.52 M33-4,3.71 M33-4 or and HX-1) which ever is the one you’re using. http://z3.invisionfree.com/PSP_Maxconsole_UPMS/index.php? is where this file is, it comes in to version full as a cso file and a lite as an eboot file,you have to register but its easy and very well worth it !!! Stylemo thanks for the tutorial i like the one for the IPOD touch a lot, if u have more stuff on it let us know. Later …..
dude,i followed all ur tutorials, my psp was successfully upgraded from3.51-3.71m33-3, thank you for that, i really appreciate ur site.but now my problem is everytime I use the internet browser,it says internal error occured,why is dat? wat should i do?
can we delete the 150.PBP in the root?
@advancedude : yeah but i think i have to make this guide for newbies.
@lo : yeah sure of course. You can delete the 150.pbp file after installing the 1.50 kernel add-on.
Always nice. I remember when I was looking for such step by step manuals. Now I just dive head on first, but heeyyyy you see how that sometimes goes XD
I tried the instructions above and when I run the update it says Incorrect or inexistent 150.pbp at root. What should I do?
I pasted the 150.pbp file at the MS_ROOT folder, is it the same as the root folder?
by the way im currently using 3.71 m33-4 psp Phat
@BossChief: maybe the 150.PBP file you downloaded is corrupt. If you think you’ve downloaded the correct file then make sure you have it placed on the root or the outer most directory of your memory stick. For example if you memory stick’s drive is F: then the file should be located in F:/150.PBP
Yey! Thank you stylemo, your the best! im now running 3.77m33-4 1.5 kernel because of you! Galing 4 Thumbs up!
@BossChief: No problem. Congatulations on your new homebrew enabled PSP. Happy New Year!

and plz i need help
thnx in advance
Thanks for the guide!
One thing I don’t get though, is the root of the memory stick on a different drive than the PSP itself? Where exactly do I put it…
@Jimbo: if for example I connect my PSP to my PC. My PC detects my PSP as drive E: That is the root of the memory stick. It’s the root of the drive. And inside drive E there are folders like PSP, VIDEO and MUSIC. Those are second level folders. So basically, the root of the memory stick means the root of the drive. Or simply, it’s the drives outermost or first level.
I hope I have explained it well.
Yeah. So I just put the 150.PBP right there?
Nevermind, I got it to work.
THANKS SO MUCH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Do this works on 3.71 M33-4?? I’ve tried already but it said that “inexistence or incorrect 150.PBP bla bla bla”…
my bad..sorry for posting b4 reading..i’ve read from the 1st comment n it’s done, the prob is solved..thanks!
where i can download 3.71 M33-2 software
@djhard: hover your mouse pointer to any 3.71 m33 phrase you see here and you’ll soon be knowing where to get them.
Ive tried to install the add on on my PSP slim w/ firmware 3.71 m334 but it only says that it is only for standard psp. im lost with that pls. help?
Uhm, I’m currently at 3.71 m33-2 After installing the 1.50 Kernel Add-on, what file path should i place the homebrew apps in so that i can run ‘em on my psp?
Oh and after installing the 1.50 kernel add-on will it still work for me when i upgrade to 3.80 m33?
thanks
OH and do i need to install 1.50 kernel add-on so that i may be able to run PSX games (EBOOT.PBP). Currently at 3.71 m33-2
Hi, i have a phat PSP currently running 3.71 m33-2 and i tried installing the 1.50 kernel add-on. i downloaded the kernel thing and put the “UPDATE” folder into :psp\game\ and put the 150.PBP file at the root of my memory stick, but when i go to GAME then memory stick in my XMB it just has 2 corrupt files and one file that is nameless, this nameless one is just a black screen when u press x or start on it :S.
any suggestions?
@Damir: I think you need to set the correct Kernel in the recovery menu.
hey, can i remove the 1.50 kernel add on? will it affect my psp’s performance?
@kevindolores: why in the first place would you want to remove the 1.50 kernel add-on? The 1.50 Kernel is a great feature that the PSP Slim doesn’t have. It enables you to run homebrew programs that makes your PSP one of the greatest devices on earth. The presence of it on your firmware doesn’t really affect the PSPs performance. But if you insist and you want to remove it, try accessing the flash0 drive of your PSP and remove the 1.50 prxs.
is this work with 3.71 m33-4? don’t see it on requirement.
@TI: Yes it works with 3.71 M33-4 but only on a Phat PSP.
