I can no longer find the firmware for the C91 on the Zenithink website. My table worked great but then the keyboard stopped working. Tried to reinstall the firmware and now it won't boot. Say's software install unsuccessful. Netflix has NEVER worked on this tablet Can someone please give me a link to where I can download the firmware for the C91?
