    psp Running 1.5 / Any other firmware from the MS [Using Pandora] Guide

    Mathieulh posted this guide to Run 1.5 firmware from the MS [Using Pandora]

    To do what you want to achieve is very easy.

    - Install the pandora firmware to the memory stick using the normal procedure.


    - Copy the files created on the memory stick somewhere on your computer

    - save your flash1 registry folder into your memory stick root

    - Extract 1.50 from a psar using psardumper.
    extract it as encrypted and then once more as decrypted (save both dumps)

    - Copy the encrypted dump folders to the root of the MS, and get pspbtcnf.txt pspbtcnf_game.txt and pspbtcnf_updater.txt from the decrypted dump, and use those to replace the ones from the encrypted dump located at ms0:/kd/

    - Get the flashemu.prx and lfatfs_patched.prx from the pandora MS files you saved earlier (they are in the kd folder) and copy those into ms0:/kd/

    - open ms0:/kd/pspbtcnf.txt and ms0:/kd/pspbtcnf_game.txt and ms0:/kd/pspbtcnf_updater.txt files using a text editor and :

    - change /kd/lfatfs.prx to /kd/lfatfs_patched.prx

    - add /kd/flashemu.prx right after the /kd/fatmsmod.prx line.

    - save the files

    Done, the 1.50 firmware will boot straight from the MS using the Pandora battery. Of course you may adapt this mod to another firmware such as M33.

    Sweet!
    I've read that this might be possible.
    First time I have seen it posted as a reality.
    Cant wait to get home and try it out.

    AFAIK, M33 won't work, as it needs a special FAT driver and patched files... as these are only for the 1.50 kernel.

    Was wondering...

    Could the Pandora battery be used to downgrade any PSP? If you purposely bricked a 3.60, or you might not even have to, then ran the pandora battery on it, you could start at 1.5? Is it that easy?
