Xiaomi 1 address book, SMS, phone flash back how to solve?

If you have backed up data before, or there is no data to be backed up in your mobile phone at present, I suggest you try to enter recovery (turn off the phone, press and hold the volume up+turn on the button to enter recovery mode) to clear all the data, and don't restore the data temporarily after turning on the phone to see if you can solve the problem. If it still can't be solved, I suggest you try to brush the line to the latest development version.

Please brush the machine according to the brushing tutorial. The sixth method is line brushing:/thread-3104435-1-1.html.
