Causes
- DJI pulled or postponed the build server-side — the most common cause, confirmed by DJI support: after firmware 01.01.02.37 started rolling out, DJI hit problems, canceled the update and postponed it. Until the build is re-served, the DJI Mimo app honestly reports "Currently the latest firmware version" to everyone, and no amount of app fiddling will make the update appear.
- Stale app state in DJI Mimo — the app caches the last version-check result, and a long-lived session can keep answering from that cache. Multiple owners found the update appeared only after clearing the app's cache, reinstalling Mimo, or logging out and back into their DJI account so the check re-ran against the server.
- Camera and phone not in a fully connected session — the version check runs over the live Wi-Fi/BLE link between the phone and the Osmo Action 6. If the camera is still showing "connecting", the wireless mic is mid-pairing, or the phone jumped between mobile data and Wi-Fi, the app silently skips the firmware query and falls back to the last known version.
- Region-staged rollout that has not reached you yet — DJI ships firmware in regional batches. Owners in Italy, Romania, Canada, and the UAE all reported the same "already latest" message on the same day while other regions could update; connecting through a VPN exit in a region that already had the build made the update prompt appear for some of them.
- Phone date, time, or region settings out of sync — the version-check handshake signs the request with your local time/region. A phone with manual (wrong) time, or a device region set to a country DJI does not serve, can make the app treat the check as invalid and report the latest version without ever asking the server.
How to Fix
- Use the manual update path in Mimo — connect the camera to the DJI Mimo app, open the Profile tab while the camera is connected, tap the last option in the list, and choose "Check for Firmware Updates". This is the menu the community confirmed picks up releases the automatic prompt misses — one owner's 01.01.02.37 update only appeared this way after the prompt had failed for days.
- Clear the app and rebuild the session — force-quit DJI Mimo, clear its cache (iOS: offload/reinstall; Android: Settings → Apps → DJI Mimo → Storage → Clear Cache and Clear Data), log back into your DJI account, then power-cycle the camera by pressing and holding the power button until it restarts. Re-connect and re-run the manual check from step 1.
- Rule out a pulled build before chasing the app — check the DJI Osmo Action 6 release notes (dl.djicdn.com) and the DJI support forums for the firmware version you are waiting for. If DJI has pulled or postponed it the way they did with 01.01.02.37, no local trick will force it: wait for the re-release or ask DJI support (live chat) to push the update to your account once it is live again.
- Retry from a clean network and a second device — disable any VPN/ad-blocker on your phone, connect to a stable Wi-Fi network instead of mobile data, and verify your phone's date, time, and region are set to automatic. If the update still does not appear, install DJI Mimo on a second phone or tablet, log in with the same account, and run the manual check from there — one owner could only see the firmware from a different device.
- If the rollout is staged by region, use a VPN — owners in regions where DJI had not yet shipped the build (Italy, Romania, Canada, UAE) got the update prompt after connecting a VPN with an exit in a major region that was already serving it (US/UK). Once the download starts, you can disconnect; the camera downloads the firmware over its own Wi-Fi connection.
- If the update appears but fails mid-install — keep the camera above 50% battery, stay within about 1 m (3 ft) of the phone, and do not touch any buttons until Mimo reports success. On failure, the camera usually recovers with a reboot; if it stays on the update screen, hold the Quick Switch button for 10–15 seconds to force-restart, then re-run the update. Repeated failures on a good connection mean the unit should go through DJI's official firmware reflash tool or a DJI Care/warranty service case.
