Problem here is not the edl cable, it's the files needed for flashing in edl mode, that Qualcomm, if I understood correctly, don't want Fairphone to give to end users.
Also, not answering to you here, Fairphone no longer provides motherboard as part end user can purchase like they did for some previous Fairphones, because it is no longer allowed by law in UE as it is tied to IMEI (I red that somewhere on Fairphone forum), only repair service can.
