Hi, I'm on 3.03 OE-C and i'm trying to put THIS theme on my psp, but, i don't know how to, please help me.

Ah. I'd avoid that theme, it almost bricked by psp. But i put it in recovery and reflashed it.

I'm guessing your on custom firmware, so just hold R whilst loading your PSP up..and it brings up recovery menu, then click Advanced.
Hook your USB cable up..click USB Flash0
Should bring up a folder on your pc. Now back everything there up. So drag it all to your desktop.

Then replace the files needed.

your right, my screen when all black.

I have had that theme on 3.40 OE-A, It is good and the click sounds sound like the normal psp error message. Good theme.

Yet again.

dont bump old topics.
