Select the appropriate binary ( .bin or .hex ) file for your intended firmware version (e.g., v1.39, v1.45, or v1.59). Enable VCC and program the flash memory.

: Use 7-Zip to extract the .7z file; if you encounter "Cannot Open File as Archive" errors, the file may be corrupted and require a repair tool like WinRAR to fix the headers.

: This restoration method is strictly for interfaces with a genuine Microchip PIC18F458 . Fake or alternative chips (like the PIC18F45K80) may require different firmware files. OP-COM_RESTORE_FTDI_to_ORI_v20830.7z

OP-COM clones can become "bricked" if you attempt an online update or use incompatible firmware. Common symptoms include:

: Software reports "Interface not found" even when connected. Select the appropriate binary (

The interface should now be recognized with a valid serial number. 2. Reflash the MCU (PIC18F458)

Verify the success of the programming before reassembling the unit. Critical Tips for Success : This restoration method is strictly for interfaces

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