How to Upgrade to 3.71 M33-3

It’s been days since Dark Alex has released something for the PSP homebrew community but with his return he brings you the third update for his 3.71 M33 custom firmware. If you’re wondering what’s new on this update, well here they are exactly according to DAX:

  • Fixed a bug in access to flash by usb.
  • HEN core: kernel prx’s with syscall exports work again.
  • PSP Slim: programmers can set the size of user memory to 52 MB by using a sfo flag.
    Check sample in sdk for usage.
  • March33 NO-UMD driver:
    * Fixed a bug that could hang the psp when exiting with home.
    * Fixed compatibility issue with Castlevania Dracula X Chronicles, and maybe more games.
  • Vshmenu: it wasn’t displaying properly with psp slim TV-OUT due to the change of resolution. Fixed.

Below are the easy steps on how to do the update on your PSP.

Requirements

Instructions

  1. Download the files here.
  2. Extract the contents of the file. Grab the UPDATE folder and copy it into your memory stick to the directory PSP/GAME/.
  3. On the XMB menu go to Games > Memory Stick and run the update. You will be asked to press X to start the update. Do so. The program will exit automatically and restart your PSP. You now have a PSP 3.71 M33-3 PSP

About the popsloader, I haven’t been able to try it yet. Actually I haven’t been using it for quite sometime. I really dig the new games around. But I’ll be glad to write something about it if a lot of people asked. Thank you all.

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.

    i found the answer..
    if ur under 3.71, either if its OFW or CFW, u will encounter an error when u scan for network if there isn’t any network available..

    when i plugged my router, it worked fine..
    but when i unplugged it, an error appears saying..

    “internal error occured. (00000001)”

    sony forum says its normal..

    that’s it! hehehe

    by the way, im on 3.71 M33-4..

    i have an update, i cud send it to u if u want..

    @cashew : mine’s working fine. You need to reset your device. You should go to Settings > System settings > restore default settings.
