You need to screw the midframe down again before trying to do a power on test, not just reconnect the battery. If you don’t, you’ll get an overheat error icon (red thermometer in yellow warning triangle) when trying to power it on because the NFC sensor is on the midplate and the pogo pins connecting it need screw down pressure to make a solid connection. (No I don’t know why NFC is needed to power the phone on, or why its absence shows as an overheat error.) After figuring this out (shut out to Go Cell Phone Repair on Youtube) the battery repair worked fine.
