When ever i turn my PSP on, there's just a black screen.

How ever recovery mode works but i don't know what to do.

Any suggestions?
Thanks

Edit: I found a recovery folder on the internet. I put it onto my PSP using the USB toggle in recovery mode.
It started the update/recovery again (yay) but then i turned away for about 10 seconds, i looked back and my PSP was off. Now when ever i turn it on, i can't even access recovery mode.

Help would be appreciated.
