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.

Try booting into recovery (hold R when starting PSP up), going under Configuration, and changing the kernel setting to 1.50 from 3.71. Worked for me, I was having the same problem.
