Update PSP version without pandora battery (part 1)

version 3.71 m33

Here is a step by step guide for installing 3.71 M33. Please note that you must be running 3.52 M33-3, 3.52 M33-4 or 3.60 M33 to begin this installation.

Note: Before installing 3.71 M33, be warned that it currently is lacking the 1.50 kernel, even on regular (Phat) PSPs. Dark_AleX does plan to release a 1.50 kernel patch within the next few days, but for now you can use the eLoader to run 1.50 kernel homebrew on 3.71 M33.

Installation Guide

1. Download the 3.71 EBOOT, and then place it in you memstick (example X:/PSP/GAME/UPDATE).

2. After that download the 3.71 m33 files and extract them.

3. Copy the UPDATE folder contained in the archive to X:/PSP/GAME

4. Navigate to the Game menu on the PSP and execute the program, it will not run unless there is 78 percent battery free.

5. Press X and the update process will start. Yes it may look similar to a regular Sony update but don't worry!

6. Once finished, the updater will ask you to press X or O to reboot. You MUST do this, otherwise you'll end up with a brick.

7. You've now successfully installed 3.71 M33
