Default [Q] Cyanogen 11 on S4 (sprint) not hanging up or ringing

Hi all, I have this problem after upgrading from CM 10 to 11
I know this had been previously mentioned in another thread http://forum.xda-developers.com/show...2635758&page=2

My question is.. With all this unified thing going on with CM11 (no longer flashing to specific carriers) is it safe to flash the AT&T gsm rils setup to a sprint phone

Im posting here because I still do not have permission to post in development related forums (less than 10post)


Fixed:

In file manager

Open settings - ggeneral settings and set acces mode to root access

Search for "build.prop" in /

Edit "ro.telephony.ril.v3=newdrivercall" by adding a "U" to the end of the line in build.prop as follows

ro.telephony.ril.v3=newdrivercallU

Reboot and enjoy
