Doubts about miui 12 installation - urgent help


May 26, 2021
I would like to know if when doing the complete procedure to change the rom, that is, unlocking the phone, installing the rom from and installing magisk, etc., would the phone signal be lost? my question is for the redmi 7 version of 3gb of ram and 32gb rom at the moment since it has many problems in the mounting of the micro sd, I want to use it with a hybrid mount (sd memory partitioned as internal for apps and external for multimedia) with a 128gb Adata A2 micro sdxc. If my redmi 8 and redmi note 8 pro were to become disabled, I will probably carry out the update procedure of the rom from that is released at that time.
