It runs on WM8650. It also has rear camera with flash and the menu button is rectangle not circle. it also came with adapter for usb and lan. i need original firmware for this model but i'm unable to identify this tablet. data from env_boot says this is wms8153 7 inch 2g model with vt1603 (audio) and vt1609 (touch). please help.
