Hi, thanks for reaching out!
How many times have you tried to reset your wristband device?
Last time we did a firmware update, I personally had to reset my device I handful of times before it went through.
After you update the app:
- Click on Settings Tab
- Click on the wristband image
- Scroll down
- Click on RESET button.
- Try installing the firmware again after resetting is done
Also, after starting the upgrade, please make sure to keep your devices really close to your phone and most importantly, keep the app open during the update.
Please do not leave the app (or press home button) during the update.
Let me know if that was successful!
