I don't know what the hardware is of your device. If it is qualcomm devices, you can set persist.vendor.radio.adb_log_on 1 to enable ril log printing in adb logs.

adb logcat -v time -b radio >d:\radio.txt

You can use APKTOOL and JADX , JADX is a decopiler tool for java and APKTOOL is a tool for reverse engineering, try with that, good luck!
