Firmware rollback possible?

4670065

Today i run update for my Tacx Flux S in android utility app. It got stuck on uploading for like 10 minutes so i cancelled it. Now my trainer wont work with any app, power led is orange (software issues?). Zwif and Tacx can both find it, but no output while pedalling... In utility app it connects fine, but update now says its up to date (3.3.40 / 1.1.3). I also tried facotry reset in app, and it did nothing, still on 3.3.40 / 1.1.3. Is there anything i can do? Like manually download old firmware and flash it, or repair the new update. Thanks for help.

    So I got the same issue. I did the following things to get it working again:

    1. Download & install the old Tacx utility App. (not in the app store anymore but still available in apk format: https://m.apkpure.com/tacx-utility/tacx.android.utility)
    2. Download the restore file that has been posted here on the formum here: https://download.garmin.com/support/Fitness/Tacx/Flux_S/restore.tacxfirmware 
    3. Download the Files by google app: https://play.google.com/store/apps/details?id=com.google.android.apps.nbu.files&hl=en&gl=US 
    4. Use de Files app to browse to the "restore.tacxfirmware" file
    5. For me there was ".zip" added to the file, remove this so it is only "restore.tacxfirmware"
    6. Click "open with" and select the Tacx utility App
    7. Click on the tacx trainer to connect
    8. In the menu goto Update
    9. Press install
    10. At 50% the app gave me an error to unplug the tacx
    11. Leave the notification open, unplug the tacx for 5 seconds and then replug
    12. Wait until boot en click "ok" on the notification in the app
    13. The update continues until it works again.

    Hope it helps someone else.

    I realise this is resurrecting an old post but i had the dreaded red / green flashing light that came out of nowhere after months of use. Trawled the internet look for help and even spoke to Garmin who gave me a patch file for the latest update that failed time after time.  Found the above post and followed it step by step and a miracle happened - my tacx flux s is now up and running again.

    Only comment to add is that i found a had to turn the power on and off a few times until i got the amber power light instead of the red/green which allowed me to apply the firmware update.

    Thanks a lot to the above poster - hope this also helps someone in the future.
