    Yes, I have put the files exactly in the same place using Easy installer. But, I had to put the files manually into the PSP because the
    Easy installer doesn't recognise my PSP drive :S. My PSP drive is L:/
    but there is no such a drive available, when trying to exctract the files, but I don't know if that has anything to do on this problem. And another thing, should my memorystick's light flash "all the time"
    when the screen while being red? The light flashes about 2,5 secs,
    then the light just jammes and doesn't flash :S. And the red screen is about 9 secs and then the PSP just goes off. So I just don't know what
    to do. I'm not an expert with these things and so...

    I just can say use the 32 MB memorystick that came with the PSP for downgrading. Should work with the first try.

    No it shouldn't, haha the 32mb stick wont make a difference. It's widely known the exploit for 2.71 is very unstable and executes about 1 in every ten tries (dev stated fact).

    Funny thing is, the 32 MB stick actually makes a difference. Had to try it myself on some PSPs. When you use a bigger stick, you need a lot of tries, with the 32 MB stick it works on first try.
