For working GPS on any custom rom, follow following steps (Root access needed)
1. Download "gps.conf" file for your region from the below link

2. Replace the file with your old "gps.conf" in /system/etc/ (or you can also rename the old file & keep it if you need it)
3. Now change the permission to rw-r--r--
4. Reboot & Done
Try testing your device with google maps in device only mode (I'd suggest for first time try testing in open air)
