Lost Twrp

[prooxmin]

hi all,
I've update my MI4 LTE 3/16 from a previous mi 8 to the miui 8 7.1.12 passing through OTA (i've downloaded .zip file and opened with the updater).
The problem is that now i don't have TWRP no more (mi-recovery power+up vol) so i've lost root's grants.
I've tried a new TWRP install,dowloader .img and using FLASHIFY but don't have root's grants.
Is there someone that could help me for let me have back TWRP and root's grants?
Thank you in advance.

From pc you can flash twrp img
Fastboot flash twrp. Img
Then
Fastboot boot twrp. Img
Allow modifications.
Reboot then twrp is back again.. Then proceed flashing supersu.
