Why does the Xiaomi 15 Ultra Photography Kit fail to upgrade?

We are very sorry for the inconvenience. The Xiaomi 15 Ultra Photography Kit needs to be connected to the phone and connected to the network during the upgrade process. Network fluctuations during the upgrade process may cause the upgrade to fail. Secondly, keep the phone and the kit fully charged. Please try to upgrade again.
If the upgrade still fails, please try the following operations:
1. Disconnect the photography kit and the phone for 3 minutes, and then reconnect;
2. If the connection pop-up window does not appear on the phone after more than 30 seconds, disconnect the photography kit and reconnect the phone after 10 seconds. Repeat this process until the connection pop-up window appears on the phone;
3. If there is still no response, try charging the photography kit and then connecting it to your phone.
