Xiaomi mobile phone installation software always fails. There are several possible reasons for this problem:

1. Mobile phone setting problem.

2. The software is unsigned or the signature is incorrect.

3. Certificate conflict.

Solution:

1: Go to Program Management-Options-Settings: Install Software is set to-All, and Online Certificate Check is set to-Off.

2. Re-sign unsigned software before installation.

3: Install after the grid machine (please make a backup before the grid machine).
