However, one must not romanticize this upgrade. It voids any semblance of warranty on the clone, and the process carries inherent risks. A slight misstep in pin-shorting or a power interruption during firmware flashing can irrevocably kill the tool. Furthermore, even after a successful update, the clone remains a clone; version 2.70 might emulate the original's functionality but may still lack the precise timing or electrical isolation of an authentic Ktag. Users frequently report that while 2.70 enables access to new ECUs, it can introduce instability with older ones that worked perfectly on 2.25. Thus, the decision to upgrade is often a trade-off: sacrificing absolute reliability for expanded vehicle coverage. The upgrade is primarily a software-driven process that
