i have heard that now, all psp versions are hackable but are there still any problems especially for the 3000? i have heard if you shut down, restart or ran out of batteries, the firmware restarts. are there any other problems? what can you do to overcome the problems? also, what happens if you update to the latest firmware, can you still downgrade the 3000 these days? what are the things you do or hacks that has high chance of bricking your psp? what are the things you should avoid doing to the psp (except the basic hacking ofcourse)?
