    It is RECOMMENDED to use the phone app to reflash the firmware which is simple. When to use the phone app, you will need an OTG adapter to connect the reflashling kit with your phone. Please refer to the video for the reflashing process.

      Works As Expected For Flashing D4V2 September 5, 2019

      It's a pretty simple flash kit, which was manufactured for the Emisar D4V2, which has flashing pads built into the driver board (the drive board doesn't have to be removed for flashing). There is some companion software to install on your desktop computer and/or phone, for it to work. The instructions for using this are on BLF (budgetlightforum.com). Look for the thread "Emisar D4V2 Flash Kit Instructions".
