Since some have had issues with the 4th Gen 8.4 conversion I am looking to gather some details into one thread. I will update as new information is found and posted.

** My plan is to host the software update files for the various 2013-2018 8.4AN's (& 19 classic) so people can update to current versions as needed and make it easier for others to stop chasing down various VINs to get updates **

I am very interested in getting actual P/N's and FW versions from each successful 8.4AN model year (this will help with verifying what we purchase from various vendors and correct FW).

** FYI. The latest v18.45.01 update for ALL 13-17 Ra3 VP3-NA and RA4 VP4-NA radios is in a separate thread at the moment & appears to require SW version 17.11.x or higher **
ROLL-UP INFO: FOTA 18.11.x & uC D/L 18.45.01 SW Update 13-17 RA3/Vp3-NA & Ra4 VP4-NA.

Useful reference from the Dodge Cummins Diesel forum about getting into various modes, i.e.

* Dealer Mode (Use this to identify your Radio's P/N and S/N !)
.. Hold Hot+Cold+Front defrost buttons for 5 seconds

* Engineering Mode
.. Hold Hot+cold+buttons for 5 seconds

* Screen Calibration
* How to save a screenshot to USBdrive

* Vehicle Shipping Mode (Reference Only, Not recommended)
.. Front Defrost + Browse/Enter for 5 seconds
my '18 ram seems to be stuck at 21.11.11, and I think the P/N is CNSC27N5GL. My picture taking skills cut off part of the label.

I'm going to try and update with '18 files this weekend.

My logic is, the LCD is damaged, so... I can't make it much worse. If it bricks, I'm looking at ~$200 more for the whole unit, versus just the LCD.

EDIT: So, I'm a computer guy. I decided to explore the update a little (22.6). The pubkey file, expires on 2048... I don't think anyone is still going to expect our old head units to work by then but... Actually, second thought, the pubkey file should only have to do with the ability for the radio to talk to the cellular towers, and I doubt ATT is going to support early gen 4G in 2048...
