Allows loading specific firmware files (e.g., version 1.39) to the interface.
The executable is a highly specialized utility tool used by automotive technicians and DIY enthusiasts to flash, repair, and restore the bootloader of cloned OP-COM diagnostic interfaces . OP-COM is a popular diagnostic software designed for Opel/Vauxhall vehicles, but budget-friendly "China Clone" hardware interfaces are prone to getting bricked or erased when exposed to newer software versions.
