Hel with homebrew

Hi, sorry for my English and if my question was answered before. I tried to install the homebrew with Indiana pwns an could not succeeded. My SD seems empty. If I go to Datamanager it says the game should be played once before I could save it.
I tried several files and some of them gave error 403. With instructions with some file there was a note that I need the original game Indiana and I shold play it tto the first level and save the game. Is it possible to install homebrew without original game because I don't have it and how.
Thanks, PP

If you have system menu 4.2 or below you don't need any games, you can use an exploit called bannerbomb to install homebrew.

If you are on 4.3 you will need a game exploit and the original game for your region.

Thanks. I'm on 4.3. Can I downgrade it to 4.2 and then do the hack bannerbomb?.

No.

You don't ever want to downgrade, its a bad idea for one another it can cause a problem and cause bricks.

It is impossible to do in your situation anyway. You want to downgrade to run an exploit so you can install HBC; but how would you run the downgrader? With an exploit. And if you could use an exploit, there's no need to downgrade.

Just pick up a copy of Indy or get Super Smash Bros. Brawl (the better choice if you're gonna want to use a game after running the exploit) and use either Smash Stack or Indiana Pwns.
