Connect your programmer (e.g., USBasp) to the cable's ISP pins.
: Ensure your cable uses the ATmega162 chip. Newer real HEX-V2 clones often use ARM/STM32 chips, which require different tools.
A device that allows you to directly program the AVR chip. vcds atmega162 reflash 2021
If MProg cannot write, ensure the cable is a 232RL version. 232BL cables often require different approaches or might not support the newest firmware.
Before starting the reflash process, gather the necessary hardware and software tools. Hardware Requirements Connect your programmer (e
Carefully solder your jumper wires from these pads directly to the corresponding pins on your USBasp or TL866 programmer. Step 2: Reprogram the FTDI Chip
: Software tools used to push hex data to ATmega microcontrollers. A device that allows you to directly program the AVR chip
Run VAGCOM_HWType.exe with the cable connected to both your PC and a 12V power source (the OBD2 port of your car). Click Read to see the hardware type and confirm if the bootloader is enabled. 2. Required Tools and Software
This guide applies only to cables using the ATmega162 microcontroller paired with a FTDI FT232RL/BL USB-to-serial chip. It does not work on NEC, ARM, or newer STM32-based clones. Part 1: Preparation and Identification
To re-program the FT232RL chip if it was also "de-bricked" or needs a specific Vid/Pid. 2. Preparing the Hardware
