Tom, it was bear trying to put this “F” connector back on. There’s a torx screw right where the connector should lay down, and it appears to put it in a bind making it difficult to seat. I’ll try to post a picture of mine.,
You should make it clear in your first picture that you are moving the card from the left to the right. Then you follow all the way around the device and meet at the rear where you started (and where the fragile tab is located)
You should clarify that in your second picture — where you show the fragile tab — the image is taken looking DOWN into the device.
