when does bricking ocour? (psp)?

Question

i want to downgrade, but i'm afraid of bricking? does it happen only in the process of downgrading, or can it happen anytime during use?

Answer 1

The reason the PSP got bricked is because the system memory got corrupted or erased. Below are the ways to brick your PSP:

1) Attempt to downgrade the PSP and something when wrong (i.e. not enough battery charge when you downgrading)
2) Try to run homebrew programs that are malicious (virus) or badly written
3) Try to mess around with the system memory yourself (i.e. change XMB icon or Gameboot)

Other than that, you will not brick your PSP during normal use.
