Stuck parking pawl from 12v death? Need help!

[Alakuu]

Looking for some help.
Drove and went to store.
Got to car. Car in flashing reboot. Oh no 12v battery issue.
Turned off headlights and heating got it to boot and go into drive.
Drove home with no issue.
When I got home I pressed the power button while in drive (I think this is the start of my problems).
Ordered battery.
Disconnected HV and 12v battery while waiting.
New battery arrived. Put on charger. Charged.
Put in new battery. Waited 20~minutes.
Engaged HV system.
Went to charge car. Car out of range of charger.
Went to pull car forward.
Car flashing that the car was in neutral not in park and needs secured.
Tried pushing car.
Couldn't push car.
Got back in car put in drive and tapped the peddle.
Grinding noise immediately pressed power button. Grinding noise stopped as soon as pressed.
I've heard parking pawls grind before. Yep that really really sounds like the parking pawl.
I've tried many things to get it to go 'back in park' so that I could then get it back into actual neutral.
What should I do here? I'm guessing either the parking module is broken (maybe that drained my battery?) or it's lost calibration and thus thinks it's in neutral but absolutely isn't.
The parking brake engage and disengage sounds like it did it's thing but didn't fix the problem.
Halp!

Pretty much exactly the same thing that happened to this guy: https://www.mybmwi3.com/threads/urgent-advice-needed-on-dead-i3-after-12v-battery-failure.19662/ Read it and see what the resolution was.

He seems to have just put a new battery in?

I've got a new battery that I charged the entire day. Read 13.7v when I pulled it off the charger.
Car isn't saying the battery is draining or anything.
Just that it's in neutral. Except the car isn't actually in neutral!


This reads almost to a T my situation.
I know the HV is at ~75-80% and it's charging right now. I'm hoping to go outside and find a working vehicle tomorrow. But if the service bulletin he mentions is correct then my parking lock module (parking pawl) is likely out of sync with the current current state and need 'calibrated?' I can't really find much in the way of 'how to do that' so my fear is this might be a dealership needs to fix it due to the service bulletin.
