That’s an excellent guide! I had to replace both the battery and the display. The iPad seems fixed and boots but shuts down after 3min/180s due to "no successful checkins from com.apple.thermalmonitord since wake". The other services listed in the dump all report successful checkins. I have no idea whether that rather indicates something went wrong with the battery replacement or with the display exchange (and associated home button transfer). A hard DFU didn’t help.
