It will be possible to fix this redmi 3s bug in next rom? It happens with stable and developer official rom too.

Hello,
When my redmi 3s pro loses network (in a tunnel, elevator, etc..), 3G network never comes back, only 2G and I have to change network preferences to recover it.
It happened with official developer rom too.
Somebody with this problem?
How can I install TWRP on my redmi 3s pro? By updater, by fastboot? Where can I download the fields for each way?
Thanks.
P.d. Need firstly to unlock bootloader to install TWRP?
