I had the problem with Google Play Services with the no call sound issue, I've been trying different ways (i'm really inexpert in this) finally I've installed a storck ROM (waiting to get any OTA update that fixes the Play Services issue) and got this (image attached).
What can I do? thanks!
Edit: nevermind I've solved waiting until device got out of battery, in charging mode I' putted it recovery and flashed a new ROM on it and then installing a different ROM.
I still have the problem with no call sound, it isn't google play services, no! it was an update for HTC Lock Screen, so please if you have this same problem deactivate the auto update function for it on Play Store.
