At the bottom of the build.prop file is a section called ADDITIONAL_BUILD_PROPERTIES and there are three lines that need editing.

ro.mot.phone mode.vzw4gphone=1 change to 0

ro.mot.ds.fastdormancy.disable=false change to true

telephony.lteOnCdmaDevice=1 change to 0 (the first instance of this line higher up in the build.prop can be ignored as this one takes precedence over it)

These changes can be made with any root enabled file explorer or with adb shell but you must always remember to set the permissions properly to rw-r--r--
and always save your original file as .bak to restore in case of problems.

If you do not set permissions properly your phone will not boot and you will need to reflash the system to restore it.

Also removing or renaming /system/priv-app/VzwPhoneService.apk and .odex files will disable the SIM from Unknown Source popup warning.
Thanks for the information. Could you elaborate on the benefit of making the edits? I understand that disabling fast dormancy will work around the bug, but what benefits do the other two edits provide?
