Before writing new data, use software like or eXtreme Burner to read and save your existing, albeit broken, firmware. If the new firmware doesn't work, you can re-flash this original file. Step 4: Write the 2021 Firmware
avrdude -c usbasp -p m162 -U lfuse:r:-:h -U hfuse:r:-:h
Perform a within the software. This wipes the blacklisted firmware completely clean, preparing the microcontroller for fresh data. Step 5: Flash the New Firmware and EEPROM vcds atmega162 reflash 2021
The is a microcontroller chip manufactured by Atmel, which serves as the "brain" of many OBD2-to-USB diagnostic cables.
: Check your soldering connections. Reduce the ISP clock speed in AVRDUDESS. Before writing new data, use software like or
(Optional) Required if your VCDS board lacks a pre-populated ICSP header.
After flashing, you must use a compatible version of the VCDS software. Download VCDS 20.4.2 or 21.3.0. Install the software. Reduce the ISP clock speed in AVRDUDESS
Reflashing VCDS on an ATMega162 microcontroller can seem daunting, but with the right tools and guidance, it's a relatively straightforward process. By following this step-by-step guide, you can ensure your VCDS interface is up-to-date and functioning correctly. Remember to always follow proper safety procedures when working with electronics and to consult documentation if you encounter any issues.
With the programmer securely soldered to the ISP pads, open your AVR burning tool (such as or AVRDUDE ). Select ATmega162 as the target device in your software.
By 2021, Ross-Tech had released VCDS version 20.4 and 21.3, which introduced support for newer car models and improved diagnostic capabilities. If your ATmega162 interface had old firmware, the newer software would not recognize it.
To prevent the cable from getting instantly bricked again by automated anti-piracy counter-measures embedded in newer Ross-Tech software, implement the following safeguards:
