So....I installed Dark_Alex's POC Custom Firmware on my psp and since then there has been numerous amounts of updating and downgrading...I then installed The new Cheat Device homebrew that recently came out....then Harley G's custom firmare..now the screen is completely black and the memory stick light is flashing...I know it was dumb to install all that stuff. Now I need someone to tell me does the Dark_Alex POC still exsist on my flash because then i think I may be able to recover my (seemed to be) bricked psp...can anyone explain this to me?

Start it up, then before it starts, put it on hold. It'll go to Recovery Mode if it's on there.

Tried it....I tried all the controls for Harley G's custom firmware nothing works....but then again I'm waiting to get into my mem stick to add the dark_alex files
