I just replaced the usb c port with a new one and that wasn't it. I have a multimeter now but I don't know how to test for the data lines. Do you have a more detailed description or a link that I could check out ?

Select diode mode on the multimeter (usually the continuity mode and diode mode mode share the same designator, so it's the mode that create a beep sound when the two prongs make contact). Then put the red probe on ground (charging port, for example) and black probe on one of the test points. I believe I put a picture of the test points somewhere in this thread. Let me know what reading you get.

Did you ever figure out the issue?
 
The datalines are connected to emi filters and sometimes they break :
