Accidentally disabled OEM unlock on rooted phone

I accidentally disabled the OEM unlock option on my rooted S7, and am now stuck in bootloop. I can get into download mode but not recovery mode.

I have tried to flash a stock firmware, however odin stops at this point:

<ID:0/007> FAIL!

<ID:0/007> Complete(Write) operation failed.

You see the message custom binary blocked by FRP lock on the top left of the screen with the Samsung white text in the middle right?

Now there are only two ways to fix this and one involves factory resetting the phone.

You'll need to reflash stock firmware preferably the latest one via ODIN.

Once that's done you'll need to wipe data in recovery mode which means data will lost if it's stuck on Samsung logo, otherwise there'll be a button to press after boot to wipe data on phone.

Here is a guide on how to flash Samsung firmware if needed:

If you have a GSM flashing box by any chance such as Z3X you can use the reset FRP/UFS option without needing to wipe data.

Make sure you are using Odin v3.13 or newer because it's required to flash 8.0.0 / Oreo firmware. If flashing firmware older than what's already on there it may not flash as well.
