the 800219500 error solved !
ummm...
1. That's not running homebrew, that's downloading it...
2. If you have 3.40 you should just live with it, the PSP isn't that bad without homebrew, go homebrew once you can downgrade or use some means of emulation
3. if you back up your stuff, it's not dangerous at all to format your stick.
*4* I think your full of bull_shit
