Home button not working after dock connector repalcement

I have just replaced the dock connector (and this corrected the problem of impossible shutdown of the phone) but now the home button is no longer functional. I am pretty sure it worked before. Any clue or suggested investigation before I commit to the difficulties of replacing the home button and/or home button flex circuit ?

Answer this question I have this problem too

Is this a good question?

Thanks. I understand you mean the tiny ZIF connector that in in fact part of the dock connector assembly, and connects to the end of the home button flat cable. I suspected a problem here, reconnected the ZIF connector, but this did not help. I am going to try again, investigating the ZIF connector functionality more deeply, and if not, I guess I will have to consider replacing the home button flex circuit, which seems to be complicated and bears additional risks… On another phone, I have successfully replaced the power button circuitry, and made the button operational again, but now the upper loudspeaker does not speak… Correcting a problem often leads to creating another, just as is the case in the replacement of the dock connector assembly.
