I’ve been exactly where you are, and can only say that despite it being maddeningly frustrating there is still always a way. It might require melting off a chip and soldering a replacement one on (with significant loss of data)
You’re well into Ship of Theseus territory once you’re replacing major chips. You’ve not really recovered the phone, you’ve just replaced big chunk of it so it’s not entirely the same phone anymore, just with extra hassle because you’ve not replaced the main board as a whole.
