It would boot into TWRP recovery or download mode but never boot. I eventually noticed in TWRP that it said my internal storage was 0MB large and found that the userdata partition was corrupt (e2fsck wouldn't work)
I've tried every combination of flashing a stock .tar and/or .pit file but nothing seems to change.
Here is the output I get when trying to repartition with odin:
