I apologize in advance for the translator, but I am from Poland. I have a problem, just by mistake I made a wrong FLASH with the XiaoFlash application and I have DRV 1,6,4. The Segway app does not see the scooter as E25E but as ESx. How to get everything back to normal? Now it holds the rear electric brake non-stop, it does not display any errors. I need BLE relatively new above 2 and DRV suitable for E25E. Please help. It is impossible to drive as it is now.
