I currently use Tomato Firmware 1.28.0000 MIPSR2-109 K26 USB AIO I want to update to the latest shibby firmware, which I thought was the following one: tomato-K26USB-1.28.RT-MIPSR2-117-AIO I get "error reading file" every time, even with erase settings/flash checked. I have tried IE and Chrome (both latest). What am I doing wrong? Wrong firmware??
