Hi all, I have received my new Mi Note 64GB yesterday and I have a couple of questions. 1. How can I get more regions and language options on the phone (MIUI 22.214.171.124 (KXEMICK) installed)? 2. The phone seems to have two systems (in fastboot screen). Can I install two different firmwares? 3. How can I root? Thanks very much in advance.
