1) UFI can't read RPMB and can't write it
2) you need restore original efs also

No, UFI box not Read and can't write RPMB

RPMB write is allowed by Z3x box only with known RPMB key

B041.... cool flahs IC

you not need resize boot and rpmb areas

resize command allow only at Samsung chip up to eMMC 5.0 revison, not 5.1
