Opcom 1.67 Firmware ~upd~

First, you need to see what you're working with. Plug in your OP-COM interface and use the OC Flash utility. This tool will read the real firmware version from the device's chip. If it shows a version like 1.70, 1.85, or 1.99, you have a fake firmware. If it is already 1.67, you are in an ideal position.

Look for a yellow exclamation mark next to an unknown device (often labeled "USB Serial Converter" or "OP-COM USB V2"). Opcom 1.67 Firmware
