I've been able to flash the largest compiled S340 SoftDevice & Adafruit Bootloader .hex file (624KB) onto the board with the JLink through nRF Connect-Programmer... However the board remains in DFU mode afterward (slow fading red LED) and I'm not able to get out of that mode (any combination of pressing the reset button does not resolve, nor is there any short between the R (reset) and the Gnd pins). Any suggestions on resolving/troubleshooting?

Are there supposed to be the two (green bars) applications within the hex file? I'm suspecting at least one of them is the base sketch of the usual transitioning DotStar RGB LED on board, which usually comes preloaded with the Adafruit bootloader.
