Ensure the software detects your device type (usually listed as Type A or Type B depending on your PCB revision).
Most unverified devices have a locked bootloader or corrupted EEPROM. You have two options:
Firmware 167 works best with specific software versions. Generally, (often labeled as 2010 or 2012) is the most stable.
If you already own an interface and need to ensure it is running 1.67 or want to flash it, here is the process.
There are many "fake" 167 firmware devices online that are actually older versions with the version string simply changed in the software. Method 1: Using OPCOM Software opcom 167 firmware verified
By following the steps outlined in this guide – inspecting the hardware, running the “Test Interface” function, attempting a safe firmware change with OCFlash, and testing on real vehicles – you can confidently determine whether your OP‑COM is truly verified. And when you are ready to purchase, choose a seller recommended by the community, avoid any device advertised with a firmware version higher than 1.67, and always ask for proof of PIC authenticity before you pay.
: If special functions (like programming) are disabled, ensure you are running the software as Administrator and that the vehicle's ignition is on. Corsa C Loop : For specific older models like the , some reviewers still suggest Firmware 1.39 is more stable to avoid communication loops.
Many of us have official diagnostic tools: TECH2, MDI, VCI… But many troubles can be searched * and solved with simplest tool: OP-
If you ever see a prompt saying “Firmware update needed” when you launch the OP‑COM software, automatically accept it unless you are certain that your interface has a genuine PIC18F458. That automatic update could brick a counterfeit device. Ensure the software detects your device type (usually
Open the plastic case of the interface and locate the main microcontroller. A will have a clear marking from Microchip Technology (often with a date code and a Microchip logo). Many counterfeit chips either have no markings, show an obviously fake logo, or use an entirely different (unbranded) silicon die. However, counterfeiters have become very good at mimicking the markings, so visual inspection alone is not foolproof.
: A verified genuine interface should show a VID/PID of 6001 when checked via Windows Device Manager or OCFlash .

Can be upgraded or downgraded to any firmware version (1.39, 1.45, 1.67, 1.99).
Yes, many users have successfully installed and run OP‑COM 1.67 with the 200603a software on Windows 10 (and even Windows 11). However, you may need to to install the FTDI drivers that the interface requires. Some users report better stability on Windows 7, but Windows 10 is generally acceptable.
unless you have confirmed the hardware is not a "locked" clone. Driver Support : Ensure you are using the FTDI 2.12.28
