Do you have a lab power supply capable of constant current and constant voltage modes? If so you can bring back your flat cell and it may come back to life. LFP is more tolerant of over discharge. I have a an ETX900 that I rebuilt that had a seriously flattened cell. Brought it back to life , rebuild the board and converted it to a fully submersible marine version. It powers my electric fishing reels, a bilge pump, and a high volume air pump for my zodiac.
Don't give up on that thing. I bet you of all people can fix it.
