You put 2 files SWI9X50C_01.14.03.00_TMO_002.005_000.nvu and SWI9X50C_01.14.03.00.cwe into the folder SWI9X50C_01.14.03.00. Restart the module (AT!RESET). Then try using absolute firmware path.
Thank you Donald. Your response led me to believe the problem was with the folder, and indeed it was.
For anyone else that stumbles into this: be aware that even when you specify --cwe and --nvu fwdwl will attempt to install the first image in the firmware folder.
In my case, I had firmware files for different devices on that folder, so fwdwl was uploading a firmware for a different modem. Deleting all other files and just keeping the images for EM7411 solved it.
