Hi. I have two problems hopefully that can be resolved quickly as I'm currently without a phone. 1) I just flashed JLB 7.0 and when I installed and ran titanium backup it says I'm not rooted. How do I gain/root my Mi-2 ? 2) I was in London and my xiaomi was fine running on my t mobile sim. Now that I'm in Pakistan I can't get the pgone to roam on a local network all I get is emergence calls and a x in the signal bars. Also I put a local Pakistani sim in and I was told phone sim locked insert original sim card. Please someone help me. Thank you greatly for any help.
