OK...
Well what you can try is by making a pandora battery and a magic mem stick using Catb50 Team's Magic Memory Stick creator, you must download the full version (60mb) here is the download link: http://www.pspmod.com/forums/psp-softwar...-lite.html(note you need windows XP not vista) download it extract it to a folder on your desktop and click on "begin" and and just follow all the instructions when thats done turn off your psp so pull out your power or take out your battery and put your pandora battery in when you have done that turn on your psp and you will see a screen with 3 differnt links click on the first one and the let it do its stuff when its done it will say "press X to reboot" do that and you should have a unbricked PSP and a CHIPED PSP too.
The situation has changed a bit. I somehow got my PSP on! I don't exactly know what happend, it just went on, I did nothing special..
It worked fine for a moment, but now, when I turn it on, it displays the psp-logo and that, and then just black screen. I can press the home button and it asks if I want to quit the game. When I click "yes", it just displays the text "Please wait..." and nothing happens. I've tried to wait, but it does nothing.
Any ideas of what to do?

Edit : Oh yeah.. Never mind. I just removed the UMD and it started working again.
