Hi all, I got my redmi note 3 pro. I have stable ROM 184.108.40.206 Who came with the phone from the store. I Have many problem with connectivity to cellular network. Im Planning (and wanna) to install the officail Xiaomi global. (V220.127.116.11.LHOMICL) I tried updating method through phone app, It didnt work. Do I need to unlock the phone? Can I flash official Global ROM without unlocking? through fastboot or other way? (when im in recovery mode Mi suite give me only the Chineze Rom) Thanks in advance.
