Hi there! I see you're having trouble with the Homedics SereneScent app where the firmware update keeps looping and won’t let you get off that page. That can really block you from using your diffuser properly. To get a better handle on this, a couple of quick questions:

- Have you tried restarting the diffuser device itself?
- Also, have you uninstalled and reinstalled the SereneScent app on your iPhone already?
- Is your iPhone connected to a stable Wi-Fi network during the update process?

Once I know these, I can guide you step-by-step through some fixes. Meanwhile, here’s a common approach to resolving this kind of update loop:

1. Restart your diffuser: Turn it off, wait about 10-15 seconds, then turn it back on. This sometimes clears any stuck update states.
2. Close and restart the app: Swipe up on the SereneScent app from the app switcher and reopen it.
3. Clear app "cache": On iOS, the closest is to uninstall and reinstall the app. So, uninstall the Homedics SereneScent app completely, then download and install it again from the App Store.
4. Try the firmware update again: Open the freshly reinstalled app and connect to your diffuser. Attempt the update once more while on a stable Wi-Fi.

If this cycle of reinstall and restart doesn’t fix the issue, there might be a deeper firmware glitch in the diffuser device itself.

Advanced step: Some users have tried forcing the diffuser into a maintenance or recovery mode by pressing and holding a specific button (like the diamond button) while powering it on, then loading the firmware update fresh. If you want, I can guide you on how to try this, depending on your diffuser model.

If none of these solutions work, the best next step would be to reach out to Homedics support or email [email protected] with your device details so they can assist further or push a fix update.

Let me know how you want to proceed or if you’ve already tried some of these steps! I’m here to get your SereneScent diffuser working smoothly again.

Are there any error messages showing on the app during this loop?

Have tried all of the above and app keeps updating

Thanks for letting me know you've already tried the main steps like restarting, reinstalling the app, and retrying the update. Since your Homedics SereneScent app is stuck in this continuous firmware update loop, this seems to be a known issue that some other users have reported as well.

Based on what I've found:
- The app tries to update firmware from version 5 to 18 repeatedly but the diffuser never finishes rebooting, causing the update prompt to appear again and again.
- The update “completes” in the app but the device does not actually reboot or move past the update, which loops back to the update screen.
- This issue often persists even after reinstalling the app and reconnecting the diffuser4 8.

Here are a few additional steps you can try to break out of this loop:

1. Ensure your iPhone is connected to a 2.4 GHz Wi-Fi network (not 5 GHz). Some Homedics devices require a 2.4 GHz band for firmware updates to work correctly. You can check your Wi-Fi settings under Settings > Wi-Fi on your iPhone and confirm the network frequency.

2. Try updating the diffuser firmware on a different device if possible. Sometimes using another iPhone or an iPad can bypass update glitches related to your specific device settings.

3. Force quit the app during update then immediately power cycle the diffuser:
- Swipe up to close the SereneScent app while the update is trying.
- Turn off the diffuser, wait 20 seconds, then turn back on.
Then open the app and see if it connects normally without prompting the update again.

4. Reset the diffuser to factory defaults if your model supports it. Usually, this involves pressing and holding a button on the device (often the power or diamond button) for about 10-15 seconds until lights blink or the device restarts. This can clear corrupted firmware states. (Check your manual or let me know your diffuser model so I can guide you.)

If none of these break the update loop, it strongly suggests a firmware corruption or server-side issue that only Homedics support can resolve.

I recommend reaching out directly to Homedics support or emailing [email protected] with your diffuser model, iOS version (iOS 18.5), and a detailed description of the looping issue. Include that you've tried app reinstall, device restart, and 2.4 GHz Wi-Fi troubleshooting already. They might have an updated firmware or device replacement option.

Would you like me to walk you through checking Wi-Fi bands or resetting the diffuser next? Let me know!

Are you satisfied with the solution I provided so far?
