How to Install 1.50 Kernel Add-on for 3.90 M33 Custom Firmware
A Custom Firmware without the 1.50 Kernel add-on is only half a Custom Firmware. Without the 1.50 Kernel on your PSP, the whole purpose of the custom firmware is defeated. 1.50 Kernel is all about the homebrew apps. I have already installed the 1.50 kernel add-on on my PSP and it’s awesome. I could still use the remote control, the WiFi sniffer and a lot more homebrew applications. So how do you install it? It’s quite easy.
The Requirements
- A Phat PSP with 3.90 M33 custom Firmware installed. This one does not work on a PSP slim but don’t fret, because there is one coming.
- A USB Cable. This is used as a connectivity tool between the PSP and the computer.
The Installation Guide
- Download the 3.90 M33 Addon from Dark Alex’s website.
- Unzip and you will find the 150k_addon folder. Copy the 150k_addon folder from your PC to PSP in this directory: PSP/GAME/
- Download the 1.50 Firmware and place it into the root directory of your PSP.
- Disconnect your USB cable and then on the XMB, go to GAME>Memory Stick then run the 1.50 Kernel Add on update.
- Follow the onscreen instructions and wait. The PSP will restart automatically after the update has been installed.
- Congratulations. Go and get your homebrew applicatons now.

IT’S WORKING!!! I’m teasing my sister right now. She’s watching TV and I keep shutting it down. IT’S SUPER FUNNY!!! You should all try it. First it didn’t work. I went to recovery mode, enabled kernel 1.50, put the files in the right place and stuff. DIDN’T WORK. Then i installed the 1.50 kernel addon and now it’s working. YAY!!!

@Matt: You sure you followed the instructions correctly? Errors in flashing might cause your PSP to brick. Be careful man and don’t get too excited. It’s better to take things slow but sure than fast and regretful.

Hey David:
Here’s your problem:
the 150.PBP file in your root folder is not named correctly because when you changed its extention it actually became 150.PBP.PBP << so all you have to do is backspace one of those .PBP and then you will have a 150.PBP file and it will work
Cheers!
