Change MTP/PTP for a Galaxy S4 w/ a Broken Screen I'm trying to do a complete backup of all data on my Samsung Galaxy S4 before I send it in for repairs.

Even though the screen is completely black and does not work (very little touch abilities), I have the Galaxy Smart Dock, which lets me output the screen via HDMI and control the phone with a mouse.

I removed the lock screen, installed Kies, then connected the phone to my computer.

Unfortunately, at one point, my phone switched from MTP to PTP, and now I cannot switch back to MTP (which Kies requires).

Everything online says to just connect the phone to the computer and swipe down to select the connection mode - I cannot do that because the screen is broken.

I also do not see any "three dot" option in Settings / Storage to change the USB Computer Connection.

Is there an option I'm missing? Am I SOL?

Again, I have full control of my device through the media dock, I just do not have that control when the phone is connected (via USB) to my computer.
If your phone is like mine, this option does not exist in any of the Settings menus.  First, connect your phone to your PC via the USB cable.  (If it is already attached, remove and reattach).  Watch your Notifications bar at the top of your screen and you will see a USB symbol appear.  Pull down the Notifications and viola, there is the option to change it back to MTP.
