I bought a F700 on Ebay. It had a software issue. The previous owner tried to do a firmware updated or something like that, so I gather, and something went wrong. He got himself into something he couldn't get out of. So i am trying to restore the software to 2.0. When I get into the BLUE screen, I do everything like I am supposed to do, but the screen goes black after about 15 to 20 seconds. It is still running, but the screen just goes black. I can reset it again, but the screen goes black after 20 seconds, and I cannot complete the update. What is going on?

Is there ANYONE with any ideas how I can get this Avic working again?
