i've done like that:
1. flashed SM-A520F_1_20171123091740_6la16j8hr7_fac, and turned phone on went till google account.
2. then download mode and flashed COMBINATION_FAC_FA60_A520FXXU2AQI2
3. started phone(booting a bit longer)
4. then in z3x box choose SM-G928T (thx to abuhuzeyf) and make RESET FRP/React/EE
5. after that flash soft, but choose HOME_CSC it will keep adb connection.
6. if not ok then repeat step 4.
7. when all done just choose from settings menu factory reset.
It worked for me.
