Hey guys whats up? Well i used to know a ton of this but stopped about 3 months ago and well my friend gave me his psp so here i go again.

A. How do i tell to make sure he dont got one of these TA-082 things??

B. He has 2.81 is there any way to downgrade or get a custom firmware without having to buy a game? Because basically he wants me to put some isos and emulators on there without devhook and i kinda want 1.50 or a custom firmware.

Thanks in advance i need to know kind quick cuz he wants it back tomorrow.
