Yes, I clean flashed this rom (wiping system and data).Redmi 3s 2gb ram..
Did u clean flashed the ROM?
Try changing sim slots..
I tested both sim slots and none worked for me.
In sim 1 it won't show even the network type (4G, H+; ...) over the network bars.
When I change to sim 2 I see the network type but I can't get a stable connection. Websites aren't loading.
Will system logs help?
