What You Need:
Step-by-Step USB Flashing:
Copy the file: Drag and drop the .zip file onto the root of the USB drive. Do not unzip the file.
Power off the Yaber Pro V7 completely (unplug it from AC power for 30 seconds).
Insert the USB drive into the USB 2.0 port (the white one, not the blue USB 3.0 port).
Plug in the projector while holding the Power button on the projector body (not the remote) for 10 seconds.
The LED indicator will flash red/blue. Release the power button. The screen will show “Updating via USB – Do not unplug.”
Wait 10-15 minutes. The projector will reboot twice automatically. When you see the Yaber logo, the update is complete.
A: Generally, no. Downgrading requires special engineering tools. Only install an update if you intend to keep it. Yaber Pro V7 Firmware Update
