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.

@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.

@Damir: I think you need to set the correct Kernel in the recovery menu.
