| Problem | Likely Cause | Solution | | :--- | :--- | :--- | | | Boot0 short failed or drivers missing | Re-short while plugging USB. Use Zadig to install WinUSB driver. | | Flashing fails at 50% | Bad clone chip (fake capacity) | Use a smaller firmware (some clones need a stripped 2.68 FW first). | | Ktag software shows v2.25 after update | You only updated the app, not the MCU | Repeat Step 3 & 4 – you missed the STM32 bootloader flash. | | Unable to read Tricore ECUs | Power supply unstable | Use a lab power supply (13.5V / 4A) instead of USB+12V adapter. | | Device works once then dies | Overheating during flash | The 2.70 firmware overclocks some clone CPUs. Add a heatsink to STM32 chip. |
