Since these are vendor drivers, I'm not exactly sure where they should be coming from. If my research is correct, they should be in the NON-HLOS.bin image (which I'm currently downloading) and subsequently added to whever the proprietary blobs are being pulled from (TheMuppets?). I gotta go to sleep early tonight because I have things to do early in the morning, but I'll tinker with this tomorrow and report back if I'm able to fix it.

update: It's taking longer than I expected to download the firmware. Finding a working link (https://samsung-firmware.org/download/GALAXY-Note-4/w820/XAS/N910PVPS4DQB3/N910PSPT4DQB3/) took some time, but the speeds are painfully slow. Even worse, the download timed out on me about 90% of the way in. I'm trying again using some internet wizardry and aria2 so I'll hopefully be able to resume the download if it times out again.

If anyone wants the QB3 firmware once I've finished downloading it, let me know. Hosting it on Dropbox would be faster.
