On RMN2 : Bluetooth modem of this rom back to version p37 again. I will try for testing.
Because p37 has a problem connection with my mi band 1s but p51 didn't.
I've just installed hermes 6.4.7 . After reboot the phone didn't connect mobile signal.
How to solve. Thanks
Now the problem has been sloved by power off the phone then remove sim --> insert again
----> power on the phone.
