As all you noticed new 6.7.1 nspro causes to may troubles to users. For me it "bricked" few phones on unlocking and imei repair. EFS backup made with nspro cannot be written back in order to fix EFS and IMEI. So it`s totally useless. However, always do EFS backup.
Hope Elco will take care of that.

In order to change/fix/repair IMEI on GS4 m919 on 4.4.2 UVUFNB4 modem/baseband has to be downgraded. Root required.

1. Root with ch-auto-root
CF-Root Download

2. Use attached Odin flashable UVUMDL modem
Modem_UVUAMDL.tar

3. using nspro fix/change IMEI

4. restore modem with attached uvufnb4 modem pulled out from stock 4.4.2
M919UVUFNB4.BLs.NON-HLOS.MODEM.tar

this modem tested many times. with other modems from other source you may experience issues with sound and wifi.
