Ring Doorbell 2 won't reset

Our ring doorbell just randomly stopped working. 'Front door is offline and not capturing video.' We have done all the troubleshooting things, including fully recharging the battery. So there is now power, but after pushing the reset button (on the front in our model) the white circle light just turns off, then back on. It does not spin, nor does it change to flashing blue or anything. Is it just dead? We have had it for 6 years.
