This article delves into the world of Vcds Hex Net Clone cables, comparing two different versions based on personal experience. We’ll examine their functionality, performance, and potential drawbacks to help you make an informed decision.
Decoding the VCDS HEX NET Clones: Two Cables Tested
Recently, two distinct VCDS HEX NET clone cables were purchased and tested. The first, advertised as a V2, was based on the Atmega162 chip and priced at $29. The second, utilizing the STM32F405 chip, also claimed V2 compatibility and cost $49. Let’s dissect the findings.
Atmega162 Cable: A HEX-CAN in Disguise
The Atmega162 cable required a separate loader executable, flagged as malicious by VirusTotal. Upon closer inspection, it was revealed to be a HEX-CAN cable, an older version incompatible with newer VCDS software.
Interestingly, the genuine Ross-Tech HEX-CAN cable also employs the Atmega162 chip.
However, the clone’s malicious loader and lack of true V2 functionality make it a poor choice. Using this cable in a virtual machine is recommended for safety.
STM32F405 Cable: A Promising Contender
The STM32F405 cable, suspected to utilize a chip similar to the genuine VCDS HEX NET, presented a different story. It functioned without a separate loader or modification to the VCDS software, contradicting the included instructions to disconnect from the internet during use.
Performance-wise, this vcds hex net clone exhibited faster logging and overall communication speeds compared to a genuine HEX-CAN. Further investigation revealed the STM32F405 chip was locked with RDP level 2 protection.
Utilizing a ChipWhisperer, the RDP2 protection was successfully bypassed, granting debug access. While RDP1 remained active, memory reading was achieved through glitching techniques. A video demonstrating the process can be found here: https://youtu.be/4JFo23tYOq0.
Conclusion: VCDS HEX NET Clone – Proceed with Caution
While the STM32F405 vcds hex net clone offered surprisingly good performance, it’s crucial to remember that using clone interfaces carries inherent risks. Compatibility with future VCDS updates requiring firmware updates is unlikely. This particular cable was tested with the unmodified 20.4.1 version from the Ross-Tech website. While this clone presents a budget-friendly option, investing in a genuine VCDS interface remains the recommended approach for guaranteed compatibility, reliability, and support.
