J700F FRP Lock remove error

Hi all.

I am sorry for making a new thread about this topic but after reading all the given threads and trying from some days, I’m still stuck on FRP lock.

I’ve tried via octopus, z3x , slide sync & also by flashing sboot and trying again for FRP remove but without any success

Its a new security I think from SAMSUNG bcz during these days I have done other phones and they are ok except this.

I’m in need of working solution please if there is,
If not so I can return the phone to client.

Thanks in advance
