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.

Just updated my firmware from 3.71m33 to 3.90m33-2. My problem is same as sohrab i cant load certain CSO or ISO game… Besides it takes a longer time to load a game as well… Probably i should switch back to 3.71 1st i guess.
