Thanks Flatric. Are you referring to the global stable rom mentioned in http://en.miui.com/a-234.html link? I see from the threads that installing a global rom on chinese XE device will unlock the bootloader and will not let gpay work.
Sorry for being daft - What build is this, before I download? I have a new Mix 2s 8gb/256gb running china stable and looking to get gpay working. Looking at the gpay issues I am considering to return the phone although I love the phone so much :-(
