I have an LG Gpad F8 on T-Mobile. I left it plugged in overnight to get charged. When I woke-up this morning the screen reads: "Firmware Update: Do not unplug the USB connection until the process is complete." The progress bar has been stuck at "0" for the last hour and perhaps all night. Tablet will not turn off. I have no idea of what to do. Tablet is new (about 3 weeks) and has been working fine until now.
