Weeks ago I published a post about Infocus M680 stock firmware file download and its flashing guide. Later, I was made to understand from the comment of Mohd Faraz that the firmware is incompatible with all M680's': it was region based.
Due to my not very flexible schedules, Mohd was able to get the World Wide (WW) version of Infocus M680 stock firmware before I could. Huge thanks to him. #thumbs
