Any advise? since it DEATH.. I don't mind to experience it if you have any idea...can post or pm me...thanks.

About 6 months ago, I tried to upgrade my firmware on the ATV1000, after
the upgrade it had a weird lockup problem. After talking to Geniatech support, they provided me a serial connector (require opening the box to hook up) to revived the box. I have attached instruction that was given to me. Try contact them and maybe they can help you. I didn't even have to pay shipping for the connector, so their support was great.
Good luck.
