    Hello,
    I recently puchased a Xiaomi Mi4 and I am trying to upgrade the version of Miui but having problems.
    I would like to upgrade to Miui v7 or Miui v7.1

    Model Number: MI4W
    Android Version: 4.4.2 KVT49L
    MIUI Version: Miui v5 KXDCNBF21.0 (Stable Build)
    CPU: Quad-Core 2.5Ghz
    RAM: 3.00GB
    Kernal: 3.4.0-g26e4aff-0900-ga93b357
    Root Permission is "off" and greyed out so I cannot change it.
    I cannot access "Manage Root Permissions"

    1. Clicking system update doesn't work.
    2. Moving update.zip to root and rebooting phone doesn't work.
    3. Moving update.zip to download_rom and rebooting the phone doesn't work.

    I would be grateful for any help and advice.

    Thanks
