What is the difference between the two files?
NM: looks like they are different timestamps and the later should be better. I am going to try and see if they can be flashed using the stock ROM. I am not finding anyway to get into the bootloader and flash TWRP. I managed to upgrade from 6.0.1 to 7.1.1 (b17) stock ROM and hoping that I can come back to if something goes wrong.
