Now here's a ray of hope for this device with a AICP ROM MM from FeyoMx/MDSdev from either of these links:-
I wish to share my gallery of the downloading and installation of the latest build http://mymidiary.blogspot.com/2017/11/mi-red-wolf-recovery-version-311-build.html
I hope that everyone has started to enjoy the latest ROM just like me and my mido in this post http://mymidiary.blogspot.com/2017/11/miui-9-week-12.html.
Kind regards. :svetius:
I hope that someone finds this post of mine useful http://mymidiary.blogspot.com/2017/11/mi-miuipro-rom-report.html:fingers-crossed:
It is an inbuilt file manager.
