After the last update with this app, my bike was bricked. Lucky enough my LBS was able to revive it (at no cost
).
As I used the app for adapting the powerlevels and checking the bike status, I didn't want to update the bike again with the risc of bricking again.
However I figured out a way to get into the app settings, bypassing the popup with the "mandatory" firmware upgrade
.
Following are the steps:
1. Disable the wifi and mobile data on your phone. You can use the 'Flightmodus' for that, but re-enable Bluetooth again. The app however will also ask for enabling Bluetooth if you didn't.
2. Start the app and connect to your ebike. It will not ask to update the Giant firmware (as it has no internet connection) and you can access all the functionality of the app after connecting to the ebike.
3. Enable wifi/mobile data again / turn of 'flightmode'. The app will now connect to maps, navigation etc. and full functionality is at your hands.
Success.
