What should I do if I fail to upgrade the firmware of the headset using the Xiaomi Earbuds app ?

Solution:

 Please refer to the following ideas for troubleshooting.
① It may be that the download of the firmware package failed, please ensure that the network is unblocked, or replace the network, and then try to upgrade again;
②It may be that the connection between the mobile phone and the headset is unstable, please try again, or try again in a place with less interference from the wireless environment;
③The earbuds app does not support updating in the background or locked screen. Please ensure that the Xiaomi Earbuds app is running in the foreground and the screen is not turned off.
