    Simply put, yes custom firmware like 3.03 OE-C and 3.40 OE-A are much better than devhook.

    Firmware is simply the software that operates the hardware, custom firmware is unofficial software not made by sony, devhook is emulation of official sony firmware i believe

    @Mailyfesu
    The newest custom firmware 3.40 OE-A is the best custom firmware.

    @Sparks135

    Okay to explain the differences. Firmware in laymons terms is the PSP's operating system. Now firmware 1.5, 2.71, 3.50, etc. are firmwares made and released by Sony. All Sony firmwares except firmware 1.5 do not let you play homebrew, your iso's, etc. Custom firmware is a firmware written by a very intelligent programmer who goes by the name Dark-AleX. It is basically a mashup of Sony's latest firmware and firmware 1.5. With it you get the latest features from Sonys firmware plus you can still play your iso's and homebrew. DevHook is a homebrew app developed before the days of custom firmware to emulate/imitate Sonys newest firmware. Thus still being able to play the new games that required the new firmware on your old firmware 1.5 psp. Essentially a virtual machine on your PSP running a virtual PSP.


    Also Spark135 if you have firmware 2.71 you can downgrade, and I can tell you how I just need to know what version motherboard you have. Use this picture to tell me...

    Downgrade to 2.71

    Files needed to downgrade...
    2.71 Downgrade Files
    Firmware 1.5 Update

    Steps to Downgrade:

    Note before your doing this charge your PSP to 100% just to make sure you won't run out of battery power any along the downgrade process. And after the PSP is fully charged leave the charger cable in for safe measures.

    1)Format your memorystick

    2)Copy all the files from the 2.71 Downgrade package to the root of your memory stick. Don't know what the root of your memory-stick is? Look below...
    [​IMG]

    3)Now extract the 1.5 EBOOT.PPB from within the EBOOT_1.50.zip file and rename it to UPDATE.PBP. Then copy the file to X:/PSP/GAME/UPDATE folder.

    4)With the AC adapter to the PSP highlight the PHOTO icon and then press Trianglethen Slideshow

    5)One of two things will happen...
    *The PSP freezes, just restart manually and try again.
    *Red screen the process has failed.Reset manually and try again.
    *Blue or green screen the process was a success the PSP will reset itself.

    6)Go to the GAME menu and run UPDATE X.YZ.
    *Note* If your battery is less than 75%, the PSP will not do anything. It will just restart.

    7)If everything goes well then it will display something like this "Doing preparations and Extracting special PRXs"


    8)After the screen will change to magenta or pink text Press X
    The PSP will show a percentage bar which is how far along the downgrade is.

    9)When it finishes it will say to press X and the PSP will restart itself.

    10)You are now at firmware 1.5!

    Nope don't mind at all. And sorry I didn't get a chance to add this bit info to my guide, but anyway after downgrading to firmware 1.5 you will want to upgrade to custom firmware 3.40 OE-A. Basically you can still play homebrew apps/games, and you have full support for the latest games. Any ways heres a link to a 3.40 OE-A Easy Installer. To install it first format your mem.stick and make sure you battery is charged up and of course keep the charge cable in it. No put your firmware 1.5 PSP into USB mode, run the easy installer, and after it is done copying the files quit the USB mode, go to the game menu and run the "3.40 OE-A Update".

    Well to begin with download the firmware 1.5 Update again, as it seems you have a corrupted download. Now delete the old 1.5 eboot you put on your memorystick. Now take the one you just downloaded, if you don't get "file corrupted" rename the file to UPDATE.PBP and put it in the UPDATE folder in the GAME folder. If you dont have a UPDATE folder go ahead and create one. Everything should work now.
