Sigh........i bought this tablet...seems like a nice tablet...till its time to download the firmware to update it. Its a winar file that extracts to a winzip file. its an img. file and winzip cannot open it. i don't know what else to do as i'm not getting any help from the Iview customer service. How do i open this image file. i tried putting onto a micro card and rebooting...didn't work either. this has been a frustrating couple of weeks. Does anyone know how to open a img. file so i can upload the firmware?
