Firmware reset steps if the wheel cannot power on:
Connect the Begode app to the EUC, then try the firmware upgrade again.
If the upgrade is not possible, press both buttons for 15 seconds to enter reset mode, then retry the upgrade in the Begode app.
If that still fails, disconnect the battery plug completely, hold the power switch to discharge the motherboard, reconnect the battery, power on, and retry the upgrade.
Key points:
Use an Android phone first.
Keep the network connection stable.
Retry several times if needed.
Follow the steps in order.
Run level calibration after the upgrade is complete.
