: The FTDI chip displays USB/VID_0403&PID_0000 in Device Manager instead of the correct PID_6001 or PID_4F50 .
Connect the device to your PC via the ICSP port if using a programmer.
: 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. 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
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. : The FTDI chip displays USB/VID_0403&PID_0000 in Device
: This restoration method is strictly for interfaces with a genuine Microchip PIC18F458 . Fake or alternative chips (like the PIC18F45K80) may require different firmware files.
: Attempting to move from version 1.64 to 1.65 (or similar) results in a non-responsive device. Restoration Steps Enable VCC and program the flash memory
OP-COM clones can become "bricked" if you attempt an online update or use incompatible firmware. Common symptoms include:
