How to Upgrade to 3.71 M33-2
Just a few days ago, Dark Alex released an update for 3.71 M33 custom firmware. The update fixed a few bugs. It also disables the VSH menu when on the onscreen keyboard. This update will let you toggle the on screen keyboard again. For the PSP Slim, a functionality to let the charge of battery when connecting a usb cable has been added. Let’s get it on with the guide.
Requirements:
- Fat or Slim PSP with 3.71 M33 custom firmware. If you don’t have a 3.71 M33 yet, here’s a guide for installing 3.71 M33.
- USB Cable
- Computer
- Make sure you have the kernel of GAME folder configured to 3.71. Shutdown your PSP then restart while pressing R then the recovery menu will appear. Go to Configuration>Game Folder Homebrew. Make it 3.71.
Instructions:
- Download the update here.
- Unzip the file anywhere on your computer. Connect your PSP to your computer then copy the contents of the UPDATE folder to ms0:/PSP/GAME/UPDATE
- Go to XMB menu and then go to GAME>Memory Stick then run the Update
- Wait for 5 seconds. Voila! You now have a 3.71 M33-2 PSP
After you have this installed, head on to the next guide on how to install update 3 for 3.71 M33. Let’s give thanks to Dark Alex for his hard work.
UPDATE: You can now skip this guide and go directly to the 3.71 M33-4 update. I wrote a guide on how to add the 1.50 Kernel Add-on for 3.71 M33. Please check it out if you need it.

hi i now having a psp slim version 3.60 m33 what must i do to update the version ?

Thanks to Sebas this worked for me..now my CSO games are working..will try an ISO file!
guys i found something tt works!!
Make sure the title of the ISO/CSO is short.
Example:
Correct — Fifa07.iso
Not Correct — FIFA-07-[PSP][EUR][www.torrent site.com].iso
——————————————————————-
Now right click on the ISO/CSO file and choose Properties. Make sure the Read Only and Hidden box is unchecked and the Archive Box is checked.
——————————————————————-
Go into recovery mode (Hold R shoulder button down while turning on PSP)
Now go to configuration then to UMD MODE and keep pressing X till you see Sony NP9660 NO UMD.
When it is set to the above setting go to BACK and press X.
Now go to ADVANCED and press X.
Go to ADVANCED CONFIGURATION and press X.
Make sure all the settings here are disabled.
Now EXIT out of recovery.
Now try the ISO/CSO.

I had my PSP (FAT) on 3.71 m33 and only some CSO games worked…I got craxy taxi and sega rally working! My Tekken 5 and Fifa 08 dont work and no ISO files read..so I booted the PSP (holding R) chnged the kernel to 1.50 from 3.71 and still no luck! I then installed 3.71 m33-2 and its still the same! Why is this? it was all fine when I had 3.52 m33-4?
