Downgrading SM-N950F firmware / removing FPR

[jdpotts]

i, I purchased a second hand SM-N950F (Note 8) of gumtree and upgraded the firmware to the latest Australian (XSA) firmware

Version 9
PDA N950FXXS8DSK5
CSC N950FOLN8DSK1

to remove the carrier lock, now after resetting the phone its FRP locked. really pissed off!!!, I tried to contact the seller but they will not respond !

I have tried to downgrade the firmware but i'm having issues with ODIN failing?? The previous release version is;

PDA N950FXXU7DSJ1
CSC N950FOLN7DSJ1

Can anyone please help / advise on how I can downgrade the firmware or remove the FRP lock, otherwise I just wasted $375......

There's nothing you can do but keep trying contact the seller others wise your out your money.

Another thing we will not discuss bypassing Google security .

You can't downgrade to a lower bootloader version so you are stuck with Pie. Also, flashing different firmware does not remove a carrier lock.
