Hi Nico and welcome to the forum. You may have noticed the increasing request for the bottom module.

Please have a look at the option to repair, though this may not be easy or the following link apparently relevant but if you search you may find notes on microphone replacement.

FP2 Bottom Module: Repair broken µUSB port and or mic

@JohnHughes (thanks again) send me two broken bottom Modules some days ago. This one has a defekt µUSB port. After disassembling I took a picture with a microscope camera and found some solder cracks. Barely to see without magnification. Two cracks at the shield contacts that I am not too worry about, but also one at contact 5. I am sure that was a slack joint. Some serious force must be acted to the Port. I will try to resolder the joints and hope the bottom module will be able to do its work…

New Fairphone 2 Bottom Module with an appropriate case

No, for now I will have to take the speaker and the vib. from a dead module and reuse them. The microphone will be a new one. But I added a filter for the differential pair and I also added a reset fuse. Maybe Fairphone will cooparete this time, if I can show a working prototype. This shouldn’t be too hard, because I can handsolder everything and the PCB is cheap to produce, because it’s only a 2 layer PCB.

I offer a repair for free if the module will then give away for free.
