: Once restored, never update the software online . Doing so will likely re-brick the device.

Connect the device to your PC via the ICSP port if using a programmer. OP-COM_RESTORE_FTDI_to_ORI_v20830.7z

The restoration process generally involves two parts: repairing the FTDI communication chip and reflashing the PIC18F458 microcontroller. 1. Restore the FTDI Chip

This guide covers how to use the toolset to repair bricked or corrupted OP-COM diagnostic interfaces. This process is specifically for devices experiencing communication errors or PID corruption (e.g., showing PID_0000 ) often caused by failed firmware updates. Understanding the Bricking Issue : Use 7-Zip to extract the

If the device is still non-responsive, the main microcontroller (MCU) likely needs new firmware.

: For stable communication, use FTDI drivers v2.8.30.0 (referenced in the archive name v20830 ) or v2.8.14.0. Connect the device to your PC via the

If your computer sees the device as a "Generic USB Serial" or shows PID_0000 , you must re-program the FTDI chip's EEPROM. : Use a utility like MProg or FT_Prog . Process : Open the tool and scan for devices.
