If pressing the phone button during the Xiaomi 17 Ultra Photography Kit Pro update process causes the update to fail, please refer to the following steps to troubleshoot:
1. The grip firmware update process involves the transfer of a large amount of data. If you leave the update interface or touch any buttons on your phone during the update, the update can fail. Please wait patiently for the update to complete.
2. If the update still fails, please check your network connection. The Xiaomi 17 Ultra Photography Kit Pro needs to have an internet connection throughout the update process. Network fluctuations during the update can cause the update to fail. You can update the grip firmware again.
3. In addition, updating the Xiaomi 17 Ultra Photography Kit Pro requires both your phone and grip to have sufficient batteries. You can try charging your phone and the grip before performing the update.
