Question Bootloader and Cert

Hello guys I need an important information ...
as we know you can make the Root of S6 edge verizon but not unlock the bootloader ...:(:(:(

I asked for info you have got to test Z3X box with the ability to unlock the booloader? or the need for a release with Z3X JTAG? ::confused::confused::confused:

I wanted to know if they knew more experienced than me by flashing a cert if an SM-G925F there was the ability to unlock and flash the bootloader always with Z3X box .... :D;)
