Sm-g920v / sm-g925v / sm-g900v

I can not reset the FRP on the g920v / g925v / g900v.

I think these phones have the most current firmware.

In the g920v the firmware is g920vvru4bog9.

I got the z3x box yesterday and installed everything properly.
The error message i am getting is "unable to read PIT"

For the G900v I am not seeing a button to reset the FRP.
g900v firmware : G900VVRU2BOE1

I still have yet to see this box work for me.
