You would be suprised how easy it is to Google tutorials for learning the basics of installing Dark_AleX firmware and installing games/homebrew and such. Instead of making threads to ask simple questions like that, Look around, and also check out the 'Getting Started' section of the forum.

Here are some links that would be helpful to you:

Look for a 2.71 downgrade (Which will make your firmware 1.50).
Then install Dark_AleX 3.40 OE a firmware (Easy installer)
Your all done. No more questions of piracy on PSP3D; I doubtt you'll stop, so just google the rest from there...
