Well, we could question if that J23 is really the serial port.
Maybe find some other reference on the 'net to confirm or refute the information in the article you are referencing.
(slim to no chance that it is wrong though)
I have not yet seen your post where you gave either the Make/Model of that adapter device or a link to the product page.
Without that, I can't access the technical details of that adapter device.
So the question about "did it damage the SoC port" will have to remain unanswered.
Also, that port is low voltage (1.8v) CMOS - easy to damage just from static electricity transfered by touching the contacts.
Translation: Keep open the idea that it has to be sent back.

Correct - that shows the setup is working down to the wire ends.
Your other photo documentation shows that part of the setup should be correct.
