Hello.

Problem with reset of FRP lock can occur if phone has latest firmware. Samsung disabled ability to remove FRP lock in latest firmwares.
Try to write "SBOOT_G928T_OJ5" SBoot file from the Support Area as a firmware, then repeat "Reset FRP/Reactivation/EE" operation.

After writing SBOOT_G928T_OJ5" SBoot file, FRP was removed. Just found out phone is locked to T-Mobile.

Tried to unlocked but failed:
