It may occur that the app informs you that it's unable to update the firmware.
This may happen when:
- You're offline.
Make sure there's no problem with Internet connection, and the app is allowed to use your mobile data (on iOS, you can toggle it on in Settings > Mobile data; on Android — in Settings > Mobile Data > HUDWAY Drive App).
- The app can't reach the server.
This sometimes happens when the host is down, but it's typically a very short-time problem, and all you need is to wait a few minutes and then give another try.
- You've run out of space on your smartphone.
Typically, the app will inform you on the update size, so it's a good idea to make sure there's enough storage.
- There's indeed some internal problem with the server or the app.
If the app repeatedly fails to update the device firmware, please email us at firstname.lastname@example.org for help.
