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 restoration process generally involves two parts: repairing the FTDI communication chip and reflashing the PIC18F458 microcontroller. 1. Restore the FTDI Chip
: Attempting to move from version 1.64 to 1.65 (or similar) results in a non-responsive device. Restoration Steps OP-COM_RESTORE_FTDI_to_ORI_v20830.7z
: Once restored, never update the software online . Doing so will likely re-brick the 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. Select the appropriate binary (
: 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.
: For stable communication, use FTDI drivers v2.8.30.0 (referenced in the archive name v20830 ) or v2.8.14.0. Doing so will likely re-brick the device
Connect the device to your PC via the ICSP port if using a programmer.
