Lg ph stuck on 0% after Unplugged usb Ask a Question September 10, 2020 Android ForumsLeave a Comment on Lg ph stuck on 0% after Unplugged usb Saw 90% before unplugging thinking battery was charged enough. Then saw the notice do not unplug until firmware update complete. Now won’t power on after close to 10 attempts. I plugged usb back in. What to do now? Source Sharing is caring!
