    I used Bob Joe's Downgrading/Upgrading app to go form 3.40 OE-A to 3.52 M33 but then I decided to go back to 3.40 OE-A so I tried with Bob Joe's app to go from 3.52 M33 to 3.40 OE-A but it didn't work so I tried to go from 3.52 M33 to 1.50 but still no success (I tried all this with Bob Joe's app).

    What do I have to do to go back to 3.40 OE-A?

    A "PSP Recovery pack" <-- Google recover to 1.50 and then install 3.40 oe-a again.

    *****@ your own discretion*****

    the easiest would just to re-install 3.40 oe-a
    you can jump back and fourth inbetween "oe-fw's"
    even the M33 since its based on oe files...

    So I have to download "PSP Recovery Pack" and install it then it'll bring me back to 1.50 and then I can go to 3.40 OE-A?

    kernal is set @ 1.5 in recovery...
    i see the thread has grow a bit.. sorry im just givin my
    2 pennies cuz lot of peeps helped me on here..
    um reason i said just to run 3.40 oe -a again is cuz
    the oe's are running "on top of 1.5" so your 1.5 files
    are still in your psp... hope that helps

    I tried the "PSP Recovery Pack" solution but I didn't find anything so I downloaded the 3.40 OE-A firmware and installed it using GAME150...

    Thanks for all your help!

    By the way, was the last CFW by Dark_AleX 3.40 OE-A? I prefer 3.40 OE-A than the crappy M33.

    he basicaly downgraded... take the folder you get and then you should paste it in the game folder....now you go to recovery menu (hold r while fully rebooting the psp)... and then run program at psp/game/recovery.... good luck.
