Are you in Hold mode?

no i am not in hold mode indeed the hold mode button was working fine for me but i have flashed it with wrong firmware so now the screen has become white but i can hear sounds by pressing buttons which means my buttons were ok (problem was in firmware)now i need exact firmware for this model.

There's a ZX-8016R firmware on mydigit.cn but I can't download it. Maybe you'll be able to figure out how.

thanks i will try to download it.are u sure that this firmware will match with my action atj2173n chipset.

wow they ripped the menu off Sunplus players??! :|
