(e.g., PICkit 2 Programmer Application). Steps to Flash opcom firmware 199 hex file patched

Before flashing any patched 1.99 hex file, you must open your OP-COM plastic casing and inspect the central integrated circuit (IC) chip. Clone interfaces generally use one of two microcontrollers, and flashing the wrong file will permanently destroy the device. 1. Genuine PIC18F458 Chip

Ultimately, the safest path for most users is to either:

The device is bricked. You will need a hardware programmer like a PICkit3 to attempt a hard reset, or replace the unit. (Optional) A PICkit 3 hardware programmer if the
