hi, I have successfully installed 6.5.12 version on my Mi5.
I have 2 small bugs which are annoying me:
1. notification reminders from google keep are working randomly. once in a while the notification appears at the right time, but most of the times it won't show at all
2. whatsapp audio...
first of all, try to speak ENGLISH ONLY, this is an international forum.
che poi sono italiano anche io e capisco tutto quello che scrivi, ma così rendi il supporto "ristretto" ai soli italiani, mentre magari altri utenti [che parlano solo inglese o altre lingue] non possono aiutarti.
just flashed it to try, and these are the steps with let me the installation succeeded.
- TWRP compatible with merged system partitions [link]
- a fastboot package of latest development MIUI ROM for aries [link]
- MiFlash installed and fully working
