Hello Users,
I have been using this trick from past 6-7 months and I have unlocked more than 10 Mi Phones by follow this procedure so stop saying that it is not working, it will work unless you focus on the steps I have provided and the "cannot Connect to the network and try again error" That issue is with your network you can try to click on add account to device 2-4 times untill it shows added successfully
Thanks!!
