I have now bought 3 different PSPs on EBay, with each seller claiming to have the much sought after v1.50
The final one arrived today, and God forbid, its version 1.51. I am aware that this can be upgraded to 2.0 and then back down to 1.50, but have no idea how to do this, and am scared that I "brick" my machine. Can someone PLEASE advise me on what to do, before I throw the damn thing out the window!!!
Thanks
