The short answer

Stop using the Air3, confirm your serial against INMO’s recall list, then install the official v3.16 via the INMO companion app (Devices > Device Settings or About > Firmware Update). If OTA fails, use INMO’s recovery/DFU tools on a PC and contact recall support with serial, photos and logs.

Time needed about 60–90 minutes in one session

Key takeaways
  • Do not use the Air3 until you confirm recall eligibility and install official v3.16.
  • You must read the exact serial on the frame, the retail box, and the INMO app and keep photos of each.
  • Install v3.16 only from INMO’s companion app or INMO’s recovery package; avoid third-party images.
  • After updating, run the recall-specific charging and short stress checks and document results with timestamps and photos.
  • If the issue persists, open a recall case with INMO attaching serial, screenshots, photos and app logs.

How to update an INMO Air3 to v3.16 after a recall

Stop using the Air3 and confirm whether your unit is listed on INMO’s recall page. If it is, update to the official v3.16 via the INMO companion app: Devices > your Air3 > Device Settings or About > Firmware Update. If OTA fails, use INMO’s recovery/DFU tools on a PC and flash the official image.

Follow the app prompts during OTA and verify v3.16 in Device Info after the reboot before you use the glasses again.

Is my Air3 part of the recall?

Compare the serial or batch code shown in the INMO app, on the frame engraving, and on the retail box against INMO’s official recall list. If any of those serials match a recalled range, treat the device as recalled and stop using it until you update to v3.16.

Record the exact serial string and keep photographs of the frame engraving and the box label for your recall case.

  • Check the serial on the right temple hinge, the S/N on the box barcode, and the Device Info screen in the INMO app.
  • If you received a recall notice, use the serial printed on that notice to match what you find.

What to prepare before you update

Charge the Air3 to at least half and keep it connected to the original USB‑C charger during OTA. Have your phone with the INMO app logged in on stable Wi‑Fi and Bluetooth enabled. Prepare a USB‑C cable and a Windows or macOS PC for recovery in case OTA fails.

Also photograph the frame serial and box barcode, and have a way to capture timestamps (phone photos and screenshots).

  • Air3 charged to at least 50% and on the original charger.
  • Phone with INMO companion app installed, logged in, Bluetooth enabled and on stable Wi‑Fi.
  • USB‑C cable and access to a Windows or macOS PC for recovery/DFU if needed.
  • Photos of the frame serial, box barcode, and app Device Info screen.

Install v3.16 using the INMO companion app

Open the INMO app, go to Devices, select your paired Air3, then Device Settings or About and tap Firmware Update. Tap Check for Updates to force the download, follow the on-screen prompts, and watch the app show download progress, Installing, then Device is rebooting. Confirm Device Info shows v3.16 after reboot.

Do not interrupt the process. If the app does not offer v3.16 and your serial is recalled, contact INMO recall support.

  • What success looks like: app shows Firmware v3.16 in Device Info and the device restarted once with normal status lights.
  • If download stalls for over 20 minutes on reliable Wi‑Fi, cancel, restart the phone and Air3, then retry.

Enter recovery/DFU and flash v3.16 from a PC if OTA fails

If the OTA update fails or the Air3 becomes unresponsive, connect it to a PC with a USB‑C cable and follow INMO’s DFU key sequence to enter recovery mode. Use INMO’s official recovery tool to load the v3.16 package and flash the device, then reboot and verify the firmware version in the app.

Only use the official recovery image and tools supplied by INMO; community images can brick the unit and may void recall support.

  • DFU entry requires the specific button combo while connecting USB‑C — follow INMO’s published steps.
  • The recovery tool should show a connected device ID and a progress bar while flashing; do not unplug until it reports success.

Verify v3.16 is installed and the recall issue is fixed

Confirm v3.16 in the INMO app under Device Info or About, then run the recall verification tests: observe charging LED and app status, run a 10–15 minute controlled stress test (video playback), and monitor surface temperature and charging behaviour. Photograph and timestamp all results.

Acceptable behaviour is normal charging indication, device warm but not hot, no sudden shutdowns, and no spike in app error logs.

  • Take a screenshot of Device Info showing v3.16 and a photo of the serial and box.
  • For the stress test, run 10–15 minutes of video and photograph the temple area immediately after with a visible timestamp.

If updating does not fix the issue

Stop using the Air3, collect evidence, and open a recall support case with INMO. Attach photos of the frame serial and box, a Device Info screenshot showing firmware, charging photos with timestamps, and any app logs or error messages and a clear timeline of events.

Follow INMO’s instructions for repair or replacement and keep all case numbers and correspondence.

  • Attach no more than three representative photos: serial, box label, and charging photo.
  • If INMO requests logs or an RMA, follow their packaging and shipping instructions exactly.

Common failure modes and how to avoid them

Most failures come from skipping serial checks, letting the OTA interrupt, or using unofficial firmware. Avoid these by photographing serials before any update, keeping the device on charger and phone on stable Wi‑Fi during OTA, and using only INMO’s official recovery package for manual flashing.

Log each step with timestamps so support can reproduce the timeline if you need recall service.

  • If you fail to record serials and photos, recall claims take longer.
  • Do not use third‑party firmware even if it appears to fix symptoms; it can void recall coverage.

Next steps you can take right now

If you suspect your Air3 is recalled, power it off, photograph the frame serial and box barcode, open the INMO app and check Device Info for serial and current firmware, then follow the update or recovery steps in this guide. Keep timestamps for every photo and screenshot.

After verification, visit /apps for compatible apps, /devices/android-xr for Android XR guidance, or /uses/live-captions for captioning apps and settings.

Frequently asked questions

How do I find the Air3 serial number if it’s faded or missing?

Start with the retail box barcode label and the INMO app’s Device Info; both usually show the same serial. If both are missing, contact INMO support and provide proof of purchase and photos; their recall team can advise on eligibility without a visible serial in some cases.

Can I install v3.16 from a third-party forum if INMO’s servers are slow?

No. Use only INMO’s official v3.16 image. Third-party firmware can brick the device and may void recall service. If INMO’s servers are slow, contact recall support to request an alternate delivery method or the official recovery package.

How long does the app firmware update usually take?

Expect a few minutes to download depending on Wi‑Fi speed, then several minutes to install and reboot. If it stalls during download for more than 20 minutes on a reliable network, cancel, restart the phone and Air3, and retry.

What evidence does INMO need for a recall replacement?

They will generally ask for the serial, photos of the serial and box, a screenshot of the firmware version, and any logs or a description of the fault with timestamps. Collect these before you open a case to speed resolution.

My Air3 gets warm after v3.16; is that normal?

A mild warmth under light use is normal. The recall fix targets rapid overheating or unsafe charging behaviour; if the device becomes hot to the touch, shuts down, or shows unexpected charging current, stop using it and contact recall support with photos and logs.
