PSP Custom Firmware 3.71 M33

M33 / Dark_AleX have worked yet another Custom Firmware wonder by releasing PSP Custom Firmware 3.71 M33 today.

3.71 M33 by M33=Dark_AleX

Changes in 3.71 M33:

- Now uses 3.71
- VSH Menu is not longer launched using HOME key, but using SELECT now. This is to not
interfere with the XMB function of home, which is now more useful in this firmware.
- Psp Slim: umdcache was allocating memory even when homebrew was launched, wasting
memory that homebrew programs may want to use. Now umdcache module is stopped before
it can allocate any memory, only in the case homebrew is launched.

Also, memory is unprotected for user memory usage by M33 core (only when homebrew is launched).
Developer, for a sample of how to use the extra memory, see the extra ram sample of the M33 sdk.

- Both version boot now from 3.XX ipl, and are independent of 1.50.

The main installer will not install 1.50 kernel anymore.
A 1.50 kernel addon for 3.71 M33 that will install inside 3.71 M33 will be released in a
few days (for fat only)

Note: due to some changes in kernel nids by Sony, you can expect a lot of kernel plugins not working anymore.
Programmers: refer to the sdk readme for details.

So there you have it, Time I think to visit the M33 website and donate.

Download: (You need both files. Read the readme.txt file in the M33 zip for instructions)

  1. PSP-Fan Says:

    I’m just charging my PSP. Once ready I’ll install it on my slim and test its all working.

  2. PSP-Fan Says:

    Ok it boots a official looking updater, but dont worry, hit x and follow it. And expect a blue screen of death (BSOD)

    It works fine, I now have M33 3.71 on my PSP slim. Thanks M33

  3. Tony Says:

    This may sound like a stupid question, but I am new to the scene and does it suport .cso games?

  4. Tony Says:

    Also, I only have a slim PSP, I can’t get 3.60 M33, does it matter?

  5. zzaz3 Says:

    I didn’t get a blue screen of death, weird. Did you hear that M33 is actually Dark_ALEX

  8. PSP-Fan Says:

    Yes .cso games will work. You’ll need Custom firmware 3.60 M33 first, before you can run this update on the PSP Slim. Otherwise it wont work.

    hey when someone gets an update on the downgrader for version 3.71 plz let me know bc i upgraded like a dumb***

  19. XxDaisukexX Says:

    You don’t need version 3.60 M33 to upgrade the SLIM to 3.71…If you have OFW 3.71 you can upgrade to 3.71 M33 using the pandora’s battery because I did it last night =]. Right here I will Explaine how. YOU NEED A PANDORA’S BATTERY TO DO THIS AND A PSP SLIM AND A CFW PSP WITH 3.52 M33-4 THAT CAN RUN HOMEBREW!!

    First download the files needed. The .rar will say “PSP SLIM Unbricker” YOUR PSP SLIM DOES NOT HAVE TO BE BRICKED FOR THIS TO WORK! IT CAN HAVE OFW 3.60 or 3.71 ON IT AND BE WORKING JUST FINE!

    Here is the link for the files.

    —————————————————-
    http://www.sendspace.com/file/tuog5t
    —————————————————-

    This FW Installer/Unbricker is universal and will work on both PSP Fat and PSP SLIM.

    Now Format the memory stick PRO duo with the either PSP, SLIM or the CFW doesn’t matter which.

    After you extract the PSP SLIM Unbriker you will see one folder named “Despertar_Cementrio”. Open that folder and copy the whole folder “Pandora’s Unbricker SLIM” into x:/PSP/GAME and make sure your CFW PSP is set to kernel 3.52 and not 1.50. Now go to game on the CFW PSP and run the “Despertar del Cementerio”. Once finished, u will have msipl.bin on x:/PSP. Now you have a UNIVERSAL psp Magic Memory stick and Pandora’s Battery. Now how to use them!!

    YOU MUST READ THIS IF YOU ARE DOING THIS ON THE PSP SLIM!!! PSP FAT DOES NOT AUTO REBOOT WHEN FISNISHED! PSP SLIM WILL AUTO REBOOT WHEN FINISHED!

    To install on the PSP SLIM insert the magic memory stick first then the Pandora’s Battery.
    Now the screen will light up but no words? So we are going to use the lights to tell us whats going on.

    When you insert the Magic Memory Stick and the Pandora’s Battery wait about 3 seconds and press X. The green light will start to blink very fast making it look almost solid. Green Means its installing.
    Then Green and Orange will start blinking together, this means the program is running. Once it is done the PSP SLIM will auto reboot. Again the PSP FAT does not auto reboot.

    To install on the PSP FAT insert the Magic Memory stick first then the Pandora’s battery.
    Press X to install 3.71 M33
    Press O to install original 3.71
    Press [ ] to dump the nand
    Press L+R+Start+Home to restore nand dump (DANGEROUS!)

    Press X and it will go through a lot of files. When it is finished hold up the power switch and manually restart the PSP FAT.

    I hope this tutorial helped lots of people! ENJOY!

    ———————————————————————————————————–

    ADVANCED USERS READ BLEOW!

    The Press L+R+HOME+start to restore nand-dump.bin
    This process is very dangerous, and you should only use it as a last resort.
    It is physical restore process (not a logical one), and will try to make
    a 100% clone of the dump.
    If you are working with a dump that isn’t yours, you will get either a brick
    or a corrupt idstorage, depending on the firmware.
    If, your PSPs NAND has more damaged blocks than the dump being restored,
    you may also end up with a brick.
