Symptoms
- App repeatedly prompts for the same firmware update after each restart
- Update appears to install but version number never changes
- Earbuds disconnect partway through every update attempt
- No error message is shown, just a repeated prompt
Likely causes
- CommonBluetooth connection dropping partway through the update transferAn incomplete transfer means the update never actually finishes installing, so the app keeps detecting the old version.
- CommonEarbuds going into a case or auto-sleep during the update processIf the earbuds power down or disconnect mid-update due to inactivity settings, the process fails silently.
- PossibleApp caching an incorrect firmware version statusA display bug in the app can show an outdated status even if the update actually succeeded.
- PossibleInsufficient earbud battery causing the update to abort partway throughLow battery safety cutoffs can interrupt an update before it fully completes.
- Less commonCorrupted firmware file requiring a full reset to clearA partially downloaded or corrupted update file can get stuck in the earbuds' memory.
What to do
- Charge the earbuds to at least 60–70% before attempting the update again.
- Keep the earbuds out of the case and actively worn or held near the phone throughout the entire update process, without letting them go idle.
- Force close and reopen the companion app before retrying the update.
- Clear the companion app's cache (Android) or reinstall the app entirely to rule out a display bug.
- Move closer to the phone and avoid any Bluetooth interference during the update.
- Perform a factory reset on the earbuds, then attempt the firmware update fresh from a clean state.
When to call a pro
If the update loop continues after a factory reset and a fully monitored update attempt, contact the manufacturer's support, since this can indicate a deeper firmware corruption needing their specific recovery tool.
Safety
Generally low risk for a careful person. Stop if anything looks different from what this guide describes.
