i did all the possible from my end.. but it is not working as it is.. even tried to switch region and update firmware from china..

anyways, i decided sent for warranty claim since still within 1 year duration.. packing up into a box with many layers of bubble protection now.. thanks..

it just started to went crazy after i clean compartment, changed side brushes and air filter.. it went backward and crash to anything then pop up collision sensor error.. gently tap or whatever method.. still behave the same.. cant even remote control as it will pop up wheel stucked or whatever.. something locked by itself..
