Mi5s Fingerprint Reader Error

May 10, 2017

I have an issue with the Xiaomi EU Rom, each time i try to update the ROM my fingerprint sensor doesn't work.
The last version that worked was 7.5.11 then i tried to update to 7.5.14 and fingerprint failed. So when i tried to go back to 7.5.11 fingerprint didn't work either.
Now am using the stable ROM 8.2.40 which fingerprint works but it doesn't have these new features among others.

What am i doing wrong when flashing the ROM or is it my phone??
Can someone please assist on this
