Updating the Firmware

Date of Update: 10/4/2018

  1. Plug your projector into power. 
    IMPORTANT: Unexpected power offs during the update process may damage your projector's firmware.
  2. Download the update file.
  3. Put the update file on a USB flash drive. 
    IMPORTANT: Be sure the update file name is MERGE.BIN and the file is located in the root folder of the USB flash drive.
  4. Put the USB flash drive into the USB port on the projector.
  5. Power the projector on. The update should automatically install, and when complete, the projector should automatically reset. Once the projector has reset, and is showing the Miroir splash screen, unplug the USB from the projector.

TIP: If the update process does not automatically start a few seconds after you power the projector on, press the reset button on the projector. This will reset the projector and power off the projector. Then, attempt the update process again.
