I found and succesfully tested a solution found here: (cannot post link)
1) download P37 here: (cannot post link)
2) reboot in TWRP
3) install above zip file as a rom
4) wipe cache and dalvik
5) reboot & enjoy :)
P.S.: sorry, I cannot post links, as I haven't sufficient reputation; ask me in PM ;)
Hello,
My phone: Redmi Note 2 Prime, with "xiaomi.eu_multi_hermes_V7.2.3.0.LHMCNDA_v7-5.0.zip"
Bluetooth seems to be very buggy, some devices (Garmin Vifofit, Garmin Vivoactive HR, Garmin Edge 510, Bluetooth headset, an so on...) with a lot of other phones works like a charm, with bluetooth...
