Installed twrp and cloudy g3. First 3 days I loved it. JUST starting today, i cannot make outgoing calls much of the time, just silence. People at work telling me they call me and it goes to voicemail after one ring. I sit my phone on the windowsill to get good signal, 3-4 bars of 4g. I call it from landline phone..... straight to voicemail. When I called t-mobile she mumbled something under her breath about lg g3 and t-mobile problems before asking me to update my software. Told her I was on custom rom so she dropped that conversation. Starting today my phone is HUNTING for signal constantly changing between 4g, 3g, H, E, and no signal at all. All over the place with the signal.

Also, no idea if it is related, but starting today. EVERY single time i try to reboot the phone I have to pull the battery because once it is off, holding the power button does nothing. A "restart" also causes this. Help!
