I have a similar problem. My phone got so hot that it turned off and when I disassembled it it was like burned in the part of the lower speaker where you were repairing. After heating so strongly the phone did not turn on and I cleaned it with flux and turned on, but now the horn is not heard and the fingerprint sensor stopped working. I see that those capacitors that you removed have the same problem and that of the fingerprints. I even tried another board and the button lights turn on but the one that got hot doesn't work and they are good. Do you think I can repair that friend?
