    I have a SuperAVR USB Development Board AT90USB-162 running at 8mhz.

    I was able to get jailbreak my PS3 Slim with this board but for some reason I can't downgrade my PS3 Fat (Firmware version 3.50) with it. I properly loaded ps3yespro_1_0.hex to the dongle. When I put it on my PS3, the light on the dongle turns red but nothing happens. Am I using the wrong hex file?

    Correct me if I'm wrong as I Downgraded and Jailbroke with an Ipod photo, but I think you would need to flash a downgrader hex (ex: PSGrade) to your board first. then flash the ps3yespro_1_0.hex to JB once you have 3.41 or lower FW on your PS3. I found a link for your PSGrade Hex here
