Known Limitations

Can You Flash “Verified” Firmware Yourself?

Yes, but it is risky. You need an external programmer (like a USBASP or TL866) and the original 1.67 HEX file (which is copyrighted and legally difficult to obtain). The process involves:

  1. Opening the OP-COM plastic casing.
  2. Connecting 6-pin ICSP pins to the programmer.
  3. Backing up the existing (corrupted) firmware.
  4. Erasing the chip.
  5. Flashing the verified 1.67 HEX.
  6. Verifying the flash against the HEX (checksum verification).

Unless you are an embedded systems engineer, this is not recommended. One wrong fuse bit and your OP-COM becomes a paperweight.
