I bricked one a week ago goofing around on a TA-082 with 3.40. I restored key 5 to unpatched state and turned it off. So, I went to Walmart and I got a PSP with a TA-079 board with firmware 2.01!!!! I had already purchased a Lumines in a "just to have it" manner 2nd hand....so You might be in luck if you go to a Walmart. I was also able to get another for a really sweet deal so I'm a little more dareing. :)
