Morotola Moto G 1st Gen Change Earpiece

How to change the earpiece of a Motorola Moto G 1st Generation. If you have sound problem during phone conversations but through the headphone the sound it is all right, it is probably a problem with the earpiece itself. You can by a new earpiece for less than 5 euros.
The first step its to remove the midframe
Remove all those screws with a Torx T5 screwdriver.
With a plastic opening tool remove the midframe starting with the corner and then sliding gently all the way down.
Carefull with power and sound volume buttons, remove then and put them aside before they fall down. And there I have found something amazing. You can see next to the camera over the earphone connector some metalic debris, it was like some kind of micro magnetic dust. I do not know how it got there, I just removed with a brush.
Unplug the battery connector you can use a pry tool like the one in the picture, it works really well.
Then pull from the plastic label that holds the battery. Do not bend the battery and use the plastic tool to help, like a lever.
Then start removing the motherboard. There are no screws, you just have to lever carefully in those places where the tool can go. Go carefully with it, remove it by the corners. The motherboard is glued to the lcd.
Open it to the side. I am not dissasembling the whole phone here, just putting the motherboard to the side to get to the earpiece.

There you can see the earpice, I am pointing to it with the pry tool
I used a very small screwdriver to remove the earpiece, but the earpiece came appart.
I just broke it. Well I had a new one anyway. But again I found lots of metalic dust behind it. I do not really know how it got there either, I just got rid of it. I am sure that it was that that was causing the hearing problem. It probably interfered with the sound vibration or something as the center of the earpiece is a magnet.

And here is the new one I just mounted. You have to place it in the same way, with the connectors in the same direction than the old one. Well, it works well now!
