Sony has released the new PSP’ firmware 6.31, which has reliability “improvements” in some titles. If you are interested in upgrading to official firmware 6.31 on your PSP, here you are the instructions…
This is an official upgrade, meaning that this procedure will revert anything you’ve done to your console, for instance, it will revert any hacking. In other words, You will NOT be able to play backup games from the memory stick, you will NOT be able to run homebrew, and you will NOT be able to downgrade your PSP to a lower version unless your PSP is 100% hackable. The Patapon 2 demo exploit has been patched, so the HBL by m0skit0 and Wololo won’t run either…
Do it at your own risk.
Upgrading to 6.31
- Download the official firmware 6.31. (for PSP Go download this version)
- Copy the 631.PBP file into ms0:/PSP/GAME/UPDATE on your MS. Create any folder if necessary.
- Rename 631.PBP file to EBOOT.PBP
- Remove your PSP safely.
- Now go to the XMB, go to game menu and run the update as is shown on the video.
