• it will pop the toast message said that the device is temporarily restricted

Answer 1

Turning off Wi-Fi and enabling Mobile Data (thank you Xiaomi for wasting my money to enabling mobile data which the last one I didn't have) on Xiaomi 4A did not work for me. Every time I tried to enable Install App Via USB it displayed me "the device is temporarily restricted". So, I found this solution:

Turn on VPN onto your device with these parameters and try again toggle Install from USB:

• Server Address: China server from https://www.vpngate.net/en/
• IPSec Key: vpn
• Username: vpn
• Password: vpn
