Two cameras suddenly stuck updating

I have a video doorbell (2nd gen, battery) and a stick up cam (battery). Both worked fine for about a week. Yesterday they both began installing an update automatically. I went to sleep thinking the update process would be finished when I woke up. The update process never stopped. The stick up cam became non-functional because the battery drained to zero during the update process. I removed the doorbell and tried removing and re-adding the device on my phone (losing all my videos in the process). Every time I re-add the device through the app it becomes stuck in the update process again. Edit: The camera and doorbell are both working again after removing them and charging the batteries through the USB plug. I am crossing my fingers that another update won't randomly drain the batteries overnight.
