My Fairphone mircophone stopped working. I checked on the Fairphone repair section which recommended taking out the microphone module and replacing it, which I did. Now, when I start the Fairphone I get the “Team Win Recovery Project” and I don’t know what to do next.
No answer from here. Hmm. I Googled the Team Win Recovery Project, eventually found an image file (.img) of the same version and that had to be copied onto the phone’s microSD card. I could then load that image from the TWRP dashboard and it all recovered. Hope this helps someone in the future.
