Methods compared

There are two broad ways onto custom firmware: the modern software route and the older Pandora's Battery hardware route. The table below summarizes how they differ so you can pick the right one for your console and goal.

Aspect Software route (6.61 + CFW + Infinity) Pandora's Battery
Best models All models (1000, 2000, 3000, Go, Street) Mainly PSP-1000 (Phat)
Hardware needed Just a memory card and the PSP Modified battery + Magic Memory Stick
Main use Standard modding of a healthy console Unbricking and installing old firmware
Difficulty Low, well documented Higher, more specialized
Risk Low Moderate, but can recover bricks
Result 6.61 CFW, permanent via Infinity Reflashed firmware, recovery state

The short version

If your PSP turns on and reaches the menu, use the software route: update to 6.61, run ARK-4 or 6.61 PRO, then install Infinity. Only reach for Pandora's Battery when you need to revive a bricked PSP-1000 or otherwise cannot boot normally.

Both paths end with a fully functional custom firmware; they simply differ in how they get there and what hardware they require.
