FRP Unlock SM-T377W, Unsuccessful on 7.1.1 ? Help Please

"FRP Unlock SM-T377W, Unsuccessful on 7.1.1 ? Help Please"

I have SM-T377W with 7.1.1

I tried to flash it with this COMBINATIONS firmware
COMBINATION_OYA_FA60_T377WVLU3ARG1

Then I used the Z3x Tool to reset FRP, it says "OK"
however, then when I put it again on Download mode it is still Locked FRP

Also when I re-flash it with OEM it still ask for Google Verification

I also tried to flash it with TWRP to Root it but I keep getting
Custom Binary Block by FRP Lock

IS THERE A WAY TO REMOVE FRP FROM THIS DEVICE ?

--------- OEM flash in this device is ----------
Canada (Rogers)
PDA: T377WVLU3BRG4
Product Code: RWC
CSC: T377WOYA3BRG4

Any Suggestions Guys ?
