How to Install 3.90 M33-2 Custom Firmware Painlessly
Howdy folks! It’s been quite sometime since my last post. I have been very busy with my family and my new work. I’ve quit my day job and I am a fulltime freelance designer and gamer now which means I have more time writing real game reviews and updates. So much for the gibberish. Let’s go on with the guide.
Like every guide that I’ve written, you will have to read every detail and follow every instructions. Of course there is always a requirement you must pass before you could continue with the process.
The Requirements
- You will need a Phat or Slim PSP with 3.80 M33 or higher ( I mean 3.80 M33-2 until 3.80 M33-5).
- You will need a GOOD WiFi connection.
- You must have 90% or more battery and have your PSP plugged in thru the AC adapter so it won’t turn off in the middle of the update.
The Painless Procedure
- On your XMB menu, scroll to the Settings > Network Update then press O or X. Select your active connection. Wait for the download to finish.
- After the update has been updated, it will ask you to run it now or execute later. If you want to run it now, press the corresponding button. If you have chosen to go back to the XMB, you can acess it by scrolling to Game > Memory Stick > 3.90 M33-2 update.
- Once you have ran the update, the screen will turn black and you will see small text on the upper left corner of the screen. Follow the instructions and the updater will automatically download the required files so you don’t have to. Once the files has been downloaded, the updater will ask you to proceed. Proceed. It will then take you to the normal SCE Updater. From there follow the instructions. After the update has finished manually shutdown your PSP by pressing the corresponding button on the screen.

That’s really a bad thing to do man! Install cfw first on your unit. Then start from there to have your unit experience the features of 3.90 m33-2.

@Bamuti: Try not using compressed ISOs. Or reformat your Memory Stick first.

I just upgraded to 3.9 M33-2 from 3.7. Stylemo greatly appreciate your well written guide that let me went through this upgrading process flawlessly.
However now i cant load some of iso files that it work fined in 3.7. The game will load with sony logo and then it goes black and freeze. I cant even switch off my psp and has to force restart it. Those games had no problem at all when i was using 3.7 so i wonder whats the problem. Only new games are working well in 3.9. Any idea ?
