Hi guys I think my SJ4000 wifi is bricked - one day I charged it with my Mi 10000 powerbank, then left it. A few hours later, I noticed that only red light is on. Strange because when you charge SJ4000, usually the whole LCD is on , showing battery charging animation. So I unplugged it from the powerbank - red light turned off. Tried pressing the power button - nothing happened. Tried putting in another (fully charged) battery and pressed power button again - nothing happened. I pulled the battery, then plug SJ4000 into my Motorola smartphone charger. Red light turned on again. But power button still does nothing. Only red light is on. Is there anything else that I can do ? Please advise. Thank you.
