A2289 820-01987 CD3217 replacement did not resolve 5v charging issue.

I have an A2289 that I am working on that came in for data recovery. I plugged in the MacBook and it was charging at 5v at .28a, so pulled out a donor board and swapped out the chips on both sides. Issue did not resolve itself, so pulled them off a different board and tried again, still no success. I can charge a different MacBook and swap boards as needed, but I cannot transfer via USB-C so I have to use Google Drive atm and it will take me 3-4 weeks to move the 750ish GB of photos that need moved. Is there anything else I can check on the board that could allow me to fix it enough to get data transferred off of the MacBook via USB?

Any history available?

Did you try to reflash TBT ROM?

The only information I have is that the device stopped charging. I also have not done that. Is there a resource you could recommend to guide me through the process?

If you have same model donor board, replace the TBT ROM.

I did some reading to figure out what I needed to swap, and it looked like I needed to change U2890. Doing so did not fix the issue, I tried with every board I pulled the CD3217 off of.

Any fault history available?

Is the machine recognized in DFU mode?
