Here is a picture that I created in GIMP based on my memory. I can try to get a device picture later but I ordered a new broadmobi modem from the Purism site and used a small piece of metal (iirc the small poker we usually use to remove SIM card, because I had it on hand) to rip the old piece of the old modem out of the Librem 5’s connector where it had ripped off into the wire connector and become stuck. Then, I was able to attach the original Librem 5 cable to the new replacement modem and have things working again.
Here I took a L5 camera pic of the defunct modem in the bag I was storing it in. I guess I should throw it out, but you can see two metal rings on the right but on the left where there should be a third one, it’s gone now.
