TK's Emisar D4V2 review

Thanks, I found the flashing kit on Hank’s site: https://intl-outdoor.com/components-6/emisar-d4v2-reflashing-kits.html

Flashing instructions for PC: Emisar D4V2 Flash Kit Instructions (Official How To)

Flashing video instructions for use with OTG Android phone: https://www.youtube.com/watch?time_continue=90&v=kyu7WOWApkc

Now to decide if I need/want to flash the firmware anyway. I should be good to go with the current version.
