G955U rev 5 (binary bit bootloader 5) NO UNLOCK?

I was unable to unlock a Tmobile S8+ G955U on Bootloader binary bit rev 5, kept getting error... I've done many up to rev 4, but this was the first REV 5 I have had and I was not able to unlock.

Is Rev 5 (binary bit 5) too new? or did I do something wrong?

I tired using the UNLOCK VIA TMB SERVER for 10 credits...
