I currently have a non-TA 082 PSP with firmware 2.60, and I want to change to 3.03 OE-A. Can someone tell me the best way to do this? There seems to be a lot of different upgraders and downgraders, and I want to make sure I'm using the right programs so I don't brick my PSP. If someone could give me instructions, or point me in the right direction it would be greatly appreciated.
