Installation: download the update HERE
ATTENTION: Me, M33Team, pspmod.com are not responsible if you BRICK your psp. ALL FILES ARE DOWNLOADED FROM M33 WEBSITE.
First method for both psp, the prefered when possible:
Requeriments: a fat psp slim with 3.52 M33-3 or 3.52 M33-4. Previous versions of M33 won't work,
due to a bug that affects them and OE; or a psp slim with 3.60 M33.
- Copy the UPDATE directory into /PSP/GAME/UPDATE and copy the EBOOT.PBP of the 3.71 Sony updater
there but with name "371.PBP". Note: the program will not even show if you copy it to a different folder than that.
- If you are in the fat psp, make sure you have configured the psp to run the game folder in the 3.XX kernel.
- Execute the program, it requires 78% of battery. If you have idstorage corrupted due to a downgrader, the program
will ask you to correct it automatically so the update can continue.
- Press X, and the Sony updater will begin. Sit and enjoy while Sony code installs 3.71 M33
- When finished, the updater will ask you to reboot (pressing X or O). DO IT. Do not skip this step
shutting down the psp by yourself, or you'll end with a brick.
- You should be now in 3.71 M33

Notes:
- This program is only for PSP fat. The program will reject PSP slim, due to the 1.50 kernel
not working on it.
- Because of lack of space, the installer will remove Location Free Player, and the korean font.

V2 UPDATE FOR 3.71 M33:From the readme:
Install instructions:
- Copy the program to /PSP/GAME/UPDATE
- If you have 1.50 addon, make sure you have the kernel of game folder configured to 3.71, or the
program will not even start.
Changes:
- There was a bug that caused corruption when writing files of more than 32256 bytes using usb flash.
The bug has been corrected, and now the implementation is as reliable as it was when it was based on 1.50 kernel.
(tested with a full restauration of a dump)
- Psp Slim: a functionality to let the charge of battery when connecting a usb cable has been added.
This feature is based on Noobz plugin code.
By default is not enabled, you can enable it in recovery.
Note that the charge of battery may be delayed some seconds since the moment you plug the cable.
- After installing this update, program at /PSP/GAME/UPDATE will always be executed on 3.71 kernel, despite configuration.
- VSHMenu: vshmenu will not be executed when onscreen keyboard is active, to avoid the lost of
the select button function in the keyboard.
An option to reset the psp has been added.
- VSH plugins are not longer executed anymore in recovery mode, that was the cause of pseudo-bricks.
Note about twi bugs remaining:
The WLAN network error, and the PSP Slim psx game change of brightness.
These two bugs are copyright of Sony
happens too in OFW.
The WLAN network happens when there is no network available, so not a big problem.

PSP developer Mathieulh has announced on the QJ.NET PSP Development forums that Dark AleX has released update 4 for the 3.71 M33 PlayStation Portable custom firmware. Here's the changelog for 3.71 M33-4:
* Bugfix: Multidisc psx games bought in the psn store would not work due to the format being different and M33 treating them as decrypted games.
* Added support for decrypted multidisc psx games created with popstation_md (supplied with this release).
This update also includes the multi-disc Popsloader Dark AleX has been working on. Here's the changelog for the new Popsloader:
* Bugfix: Games without compression had sound issues when using 3.72 pops. Fixed.
* Added support for multidisc px games created with popstation_md.
o Note: multi disc games will only work in 3.71 and 3.72 pops. Previous pops will exit to the xmb with generic error 0x80000004 when attempting to run multidisc games.
All you need to enable update 4 is a previous version of 3.71 M33 on your PSP. There's more info in the readme file included in the download.
