got a jtag from my friend, he said its been working for him for about 2 to 3 years, got it and had for about two days, i deleted a game off my HDD and turned it off after that for about 30 minutes. went to get back on and nothing happened, just the middle light of the ring turns on , just have a black screen with no sound. i left it on maybe thinking it would boot , did nothing. even left it unplugged all night and tried the next morning, still nothing. also tried unplugging hdd and tht did nothing. please help . thx
