Hey everyone -
We’ve been investigating why some returned units are not taking the firmware update as expected. Thanks to all those who’ve been working through this with us! There’s a few steps we’d like to detail
Before updating firmware
- Verify you’re using the latest version of Zwift Companion. Please check our Latest Version thread, and confirm build numbers on the Google Play Store / Apple App Store
- Keep the phone within line of sight of the Hub trainer.
- Do NOT let the phone sleep. Be sure your phone is charged fully, or plugged in to AC power.
If you attempt a firmware update and it fails:
- Force-close the Companion app and re-open. Rebooting the phone would ensure a clean restart.
- Do not press the Forget button in the Companion app.
- Do not uninstall and reinstall the Companion app.
If several attempts fail, contact us for next steps.
