from Playboy21:

TrickBrick is back!! This time around, it's TrickBrick v5 Official Style. This new trick tool uses the similar installer that is used in official firmware updates and newer M33 updates. This tool would be perfect for you to trick your friends into thinking they've bricked their psp unit when upgrading their firmware.

The concept of this is really simple. Your n00b friend wants his psp's firmware upgraded to a newer firmware. He brings it to you. You slip this brew' in his stick without him realizing. Then boot it, and enjoy the show mwahaha.
