Hello, unfortunately the problem with this error appears on the display
PLEASE GET THE APPROVAL TO USE FACTORY BINARIES (PIT)
it is the closing by samsung with the new firmware with the new security patches to write the combination file on the new 2019 recent models of their devices, at the moment there is no solution to all this, even if you try with odin or with others box or dongle to flash the combination you will always receive the same error.
Use this method without combination
