see this http://forum.xda-developers.com/showpost.php?p=64161125&postcount=3 U can read that :Hoping can help someone with Mi3:
- installed 6.1.28 from updater app > loose root and TWRP, need reinstall TWRP from fastboot and reinstall supersu
- installed 6.2.4+supersu (both zip files) from TWRP > twrp still and also root still there. I don't know why TWRP tell me that supersu isn't installed but all programs that need root works well.
if TWRP offers you to keep /system read-only, indeed keep it read-only.
If TWRP tells you SuperSU is not installed, and asks you to install it, do not do it, you will break things!
