If OTA fails, I suggest you go to MIUI Forum -MIUI to download the complete package installation update of your model.

Please brush the machine strictly according to the brushing tutorial, otherwise there will be problems.

Please follow the brushing tutorial:/thread-3104435-1-1.html.

At the same time, please download the appropriate brush package:/thread-7084703-1-1.html.
