Ring Indoor Cam (2nd Gen) firmware update is stuck or failed

The checks in more detail

the camera must stay plugged in and online, with a good Wi-Fi signal, for the download to finish. Check Device Health for the signal. A weak reading means the download fails and retries, so move the router or add a Chime Pro nearer the camera. Make sure the power adapter is firmly in and the outlet is not controlled by a switch that is off at night, which interrupts updates. Power cycle the camera by unplugging it for ten seconds and plugging it back in, which Ring gives as the power cycle for plug-in devices, then wait. Do not unplug it during an update.

Update the Ring app, which has to be compatible with the camera. If the version in Device Health has not changed after a day, restart the router and check that the camera is online by opening live view. A camera that shows offline needs the offline steps first. If the camera is online with a good signal and still sits on an old version for days, reset it by holding the setup button on top of the camera for 20 seconds, which is Ring's factory reset, then set it up again, which forces a fresh connection and the latest firmware. Keep a note of the version before and after.

Updates bring security fixes, so do not ignore an old version for weeks, and contact Ring support if it never updates. The Indoor Cam is often plugged in behind furniture where Wi-Fi is weak, which is a hidden reason for a stalled update. Move it temporarily nearer the router for the update, then put it back, and check the version in Device Health afterwards. If the camera sits on a shelf with its cable pulled tight, a loose plug can drop power briefly and interrupt the download, so seat the plug firmly and use the cable clip to keep it from being tugged.
