- For Fat / Phat PSP users You need to have a minimum of 3.52 m33-4 (update no.4 is a must) or higher to install this firmware , this can't be installed on a 1.5 firmware psp . If you don't have it see following the tutorial here.
- This custom firmware works for both PSP fat / phat (1000 series) as well as the Slim PSP (series 2000) ,but you can't install the 1.5 kernel on a Slim PSP.
- Follow these steps carefully and everything will be alright , as it flashes your psp it does have a very minimal risk , nothing to worry about if all the steps are followed correctly.
Step 1
Format your psp (make sure you back up your files first) go to system settings and choose format memorystick and connect it to your PC . Formatting is not compulsory but recommended. Make sure your battery is 100% full.
Step 2
Download the 3.90 M33 easy installation pack (compiled by igizmore) from www.igizmore.blogspot.com/2008/05/psp-390-m33-easy-tutorial-guide.html.
Step 3
Open it with WinRAR ( not winzip) if you don’t have WinRar download it from www.Winrar.com.
Step 4
So open with Winrar and copy the PSP folder to the root of your memorystick, If it asks you whether it can over write click on “YES”. Note: the Root of the memory stick is the drive that pops up when you connect your PSP to your PC eg removable hard disk (H:) , (I:) etc, its the place that contains the PSP , ISO , MP_ROOT folder , if you still don't get it see the picture here.
- Important step : After copying the files, Go to your recovery mode (if you don't know how see the video here) >Choose configuration > Game folder homebrew and set to 3.xx kernel (eg 3.52 kernel , 3.71 kernel etc) even if you have a slim psp.
Step 5
Restart your psp , Scroll to game > memorystick and click on the black " PSP Update ver. 3.90 " aka 3.90 M33 icon. ( battery should be full )
Step 6
It will unpack , then it will ask you to click on start , accept the users agreements and ta da... it will install (probably take like 2 min.). Then Done.
Step 7
You can now delete the update folder, or better still format your psp. I Recommend Fat/ Phat PSP users to install the 1.5 kernel on their PSP tutorial here - to unleash your homebrew power.
Tips
- Faq:
