So far, TWRP is done. The instructions are on up above, some have had issues with flashing modified vendor partition.
@DrScrad had issues and I provided a modified super, he had issues with flashing. I flashed it on my Wife's phone from stock without issue, so proceed with caution. The modified super disables forced device encryption for better comparability with TWRP, TWRP currently has decryption options but with FBE enabled it will not decrypt data. I have not yet tried manual encryption for comparability.
