Allow a documented Chromecast firmware update to finish before troubleshooting the sender app. The receiver may be unavailable during installation; repeatedly interrupting power can prolong recovery rather than establish a playback fault.

Why this happens
Firmware installation changes the receiver itself. App permissions and service passwords cannot make an updating device immediately ready.
Work through the steps
- Check the receiver's screen and Google Home status.
- Compare the behavior with Google's firmware-update guidance.
- Keep the required power connected while the update completes.
- Retest a known supported Cast app after normal startup.
What to avoid
Do not unplug the receiver mid-update or promise an exact completion time. Use Google's model-specific guidance if it remains stuck.
Know what changed
The receiver should return to its normal ready state before playback testing. If it does not, report its model and update-screen behavior rather than an IPTV login error.
