Root Custom Binary blocked by FRP lock

[Beautiful Oblivion]

Hey...I downloaded this app from google play and after I purchased it, it told me I then needed to download the KWGT app for it. So...I did. It then told me I needed to restart my phone. I did...and now I can't even get it to turn on. It just flashes like it's starting up. Home screen pulls up but then it says "Custom binary blocked by FRP lock." About 6 weeks ago my husband supposedly rooted my phone (either w/ Kingroot or TWRP) but I never saw a difference in it's hardware in/capabilities. I never had complete access to this stupid thing. It's possessed by "Bloatware Bixby." (Hence the need for a root.) Anyway...Can you plz direct me on where I need to go to fix this, or to the closest trashcan**

You probably need to flash the stock firmware. What is your complete model number?

It's a Samsung Galaxy J7 Pro (Samsung-SM-J730G 2017) I tried to download a new driver for/to it. My pc couldn't find the device to install it. It was basically reading it as a memory card.

Are you able to get it into Download Mode?
Should be able to get the firmware for your country/ carrier here

Lol...I can't find any firmware from the US. What's the worse that could happen if I use a flash file from Australia?

This phone model not sold in the US.
You may be better off trying to use Smart Switch. It will download and flash the correct firmware based on your model number and SN.

Nothing is working. I've tried flashing it w/ several different ones and they all keep failing.
