I just read this entire thread and it seems like no one has this problem yet!
The throttle works fine. I can change it from eco mode to standard mode & I can syn it with the MI app. But when I push the button to turn ON the lights, it powers off the scooter! and the lights stays on. And when I push the button to turn OFF the light, the scooter turns back on again.
So far I disconnect/reconnect the battery, check every cable for damage, update the firmware via the MI app. Even reset battery BMS button. Nothing helps.
Does anybody know what causes this? It will be great to have the built-in lights working so I can ride it at night. Thanks!
