Ensure your laptop is plugged into a stable power source. Insufficient voltage to the USB ports can cause reading and writing protocol operations to fail.
While OBD-II flashing provides a non-invasive method for performance enhancement, it requires a deep understanding of voltage stability and protocol compatibility. Future research should focus on the encryption levels of Ethernet-based (DoIP) diagnostics in electric vehicles. To help you further, could you tell me: Are you using an original Alientech device or a clone ?
