if it doesn't install to the flash, there's almost 0 possibility to get it bricked i think.
the bricking usually happens when you delete anything from there by accident, or overwrite it with broken/incompatible files. i guess the bricking's sorta like if you deleted system32 from your windows, and don't have a windows install disk to install a new system.
they should've made the psp with built-in hardware-based recovery mode and a read only area with factory settings and base firmware, so in case psp gets bricked by anything, you could force a complete wipe and reinstall of firmware/flash memory with that.
