Moto E 2nd gen xt1528

HELP!!! Can anyone tell me how to change the mode to nv_only instead of ruim_only, i tried to change it to nv_only but it just goes right back to ruim_only. I also want to change the prl but that is not sticking either, and some data settings also are not sticking. Does anyone else have this problem with the moto e 2nd generation(xt1528)? Answers how to fix it would be much appreciated!!!

thank you

Does Sprint XT1526 Have Different Hardware than Verizon XT1528?

Basically what I want to know is if I can unlock the bootloader of the Sprint XT1526 and flash Verizon firmware to it so that the phone will work on Verizon. If the hardware is the same it should work but of course, I don't know if the hardware is the same. Specifically, I want the LTE bands for Verizon to be enabled.
