Yes. G965F is the Exynos model.
It'll work just fine on your device. Just keep in mind, since it's a downgrade, you will HAVE to wipe all your data.
Downgrading without wiping could get you stuck in a bootloop, and you'll lose data if you haven't backed it up.
Thank you. I understand.
This will be the last step in a journey. The S9+ had been upgraded to Pie before it was given to me. And I've no data on it. In order to get call recording to work, which I need, and after much research and reading, I went the TWRP, no-verity, Elementalx, Magisk 18.1 route. Always following instructions to the letter.
The phone would initially power on, I'd set it up but no matter what I did after that, (use smart switch, not use smart switch, Google restore, no Google restore, install apps one by one), invariably I end up eventually powering on into a bootloop. And the front camera never worked, always locking up.
So, boot into TWRP, wipe data, start again with the next attempt.
Now I'm at having wiped data in TWRP, and not bothered installing no-verity, Elementalx, or Magisk 18.1 and just booting the damn thing into Pie, unrooted. The next bootloop, if it happens, will bring me to where I came to you and the flashing of Samsung Oreo to the S9+.
I am hoping, therefore, that the flashing of this Oreo build through Odin, will be the last I'll have to do and the phone will work, finally.
So, just to make sure, I'm going to boot into TWRP, choosing WIPE and FORMAT DATA, power off, boot into Download Mode, and flash the Oreo build you sent me with Odin on my PC.
Will that be correct?
Thank you for your help.
