    Hi,

    I have a serious problem. I upgraded my cell phone Xiaomi Redman Note 3 "MIUI 7.0 stable" rom to "MIUI 6.1.7" developers rom. After the update on both SIM cards can only 3G network frequencies to communicate. There is no 4G availability. How can I fix this?

    You can go to tools, updates, click updates, top right-click on the three dots, reboot into recovery
