Well then, you did everything correctly and should work. Time to file a claim and return the unit to seller. Sorry.

Sounds like your UAX module is bad. With no sound at all then I'd have that checked out. We can do a bench test on all components or just the module if you like to go that route. HD UAX should work just fine in a DT, only issue can be cargo camera and/or steering wheel controls, it shouldn't stop the unit from displaying anything. If your programming is correct, you can double check it by performing a canbus reset which will allow the UAX to display image for one cycle. Since you did this and still have black screen then again its the UAX module.
Feel free to reach out to our sales team for a bench service if you want to know for sure.

Seems that I can find every sw version but 39.7. Does anyone have a link for it? Anyone successfully downgrade?

39.7 was unreleased as it was riddled with problems. There is a 39.9 for the UAX but its best to just go to 40.1 as its the last update for all Uconnect 4s including the UAX 12" system.

Looks like anything after 39.7 looses performance and off road pages.

finally got my files back Update PR39
Is it possible to swap a 2019 Uconnect 8.4 with Nav for a 12" with nav and keep the function of the CD Player & LTE Wi-Fi in the truck?
I would like to do a UC5 to have Wireless CarPlay but staying UC4 is fine.

Yes. I had the 8.4Nav and did a full swap. I had to get in touch with the Uconnect engineers but I was able to use remote start, WIFI, and Ram Connect

If you stick to UC4 then yes, you can contact Uconnect Services to have them swap over the service to the "new" radio. You'll have to give them what ever info they need to get it working. But as for UC5, no, those use a separate module for telematics which your vehicle will be missing if you upgrade to UC5.

You want the full UAX bezel? The knob itself isn't usually sold solo but you can get a replacement UAX screen/bezel. If you found one from a junk yard that had broken screen you can swap the screen to the bezel that works. Otherwise just buy a replacement UAX bezel/screen.

First post, I'm just dropping this here because this thread was very helpful in answering questions while adding the UAX to my 4th Gen 2014 Ram. Here is how you can get your radio unlock code for free...
The Anti-Theft Code is easily deciphered, get the last 4 of the serial number form the radio module (not the screen), for example; last 4 of 0313. To decipher:
100 - 03 = 97 (100 minus first two characters of the last 4 digits of the serial number)
99 - 13 = 86 (99 minus last two characters of the last 4 digits of the serial number)
Full unlock code is 9786.
I believe this will work on all UAV/UAX/UAQ/UAS radios (probably all the Canadian versions of the same as well). Credit doesn't go to me but another member on ramforum whom I had a chat with but I'm failing to remember at the moment.
For those whose screen touches aren't working (or knobs aren't responding). I'd recommend opening the radio up and ensure all cables are seated properly. When I opened mine to remove the screen, I noticed what appeared to be a ribbon cable unseated from the factory.
EDIT: Question for anyone with AlfaOBD willing to check. Can you go connect directly to the 2017+ radio navigator module -> select the battery -> read system status and tell me what is listed for the current cabin EQ curve (should be a number)?
