[Sprint  Galaxy Note 4 Android Development] GROOVYJOSHCLARK:
Two things, I dont write or maintain the ROM's, I only assist with end-user issues like you are having. Second thing is, I have VERY clearly stated (many times) COG5 is what you should be using, this is the preferred version for baseband/kernel (until you install AOSP then that kernel used) for what is available with AOSP out there right now. I will write the steps out again to better help you.

Follow these steps and you will have a fully operational AOSP with everything working (make sure you have backed up all of your texts and anything on the internal SD BEFORE going forward):

PREP before we begin:

Download N910PVPU4COG5.tar (google search it and it will be found in XDA fairly quickly), extract the file and rename to .TAR (only .TAR, remove the .MD5 extension)

Steps:

REBOOT into recovery (assuming you have TWRP already installed, if not install the latest TWRP BEFORE going further)

While in TWRP (and ONLY AFTER you have backed up anything from you want to keep from the INTERNAL SD card), wipe the following partitions 3X's:

/dalvick

/data

/system

/cache

/INTERNAL STORAGE

-------> DO NOT FORMAT EXTERNAL SD CARD <-------

Then format internal SD (internal memory), TYPE YES on the confirmation

Do this 3 times, and perform a factory reset in between (at least 3 resets). The order isn't as critical, but I always do it this way - factory reset, wipe partitions, factory reset, wipe partitions, factory reset, format internal storage. Once those steps are performed, reboot into download mode, connect phone (while in download mode) to the PC, then fire up Odin (always have the phone in download mode before opening Odin or it may not be found until you close and reopen Odin), while in Odin, select the AP tab, browse to the .TAR (COG5 you downloaded prior), push the .TAR to the phone through the AP tab. Once this is done and the phone is reset, go through a quick setup and configure the phone (only the bare minimum and basic to get you through to the launcher). Once this is done, go to settings, update, and activate the phone (this is a process called Chameleon - SELF SERVICE), update PRL, and update profile, then activate one more time and shut down.

At this point you have a fully restored N4 on Sprint network which is activated with the updated PRL information. Shutdown back into download mode, install the latest TWRP.TAR. Reboot into recovery, wipe the partitions again 3X's:

/dalvick

/data

/system

/cache

/INTERNAL STORAGE

Then format internal SD

Do this 3 times, and perform a factory reset in between (at least 3 resets).

-------> DO NOT FORMAT EXTERNAL SD CARD <-------

Reboot into recovery, and install the AOSP of your choice, I prefer Emotion Version 9 (the latest available) as this works with Bluetooth AND GPS and has ZERO issues whatsoever, or choose the latest CMRemix, or CM13, whatever you wish to use, I go back and forth between them all but mainly use EM ver9 as it is stable and fast. Once the ROM is installed, install GAPPs of your choice, I prefer the one in the Emotion OP recommendations latest version. Reboot into AOSP and configure away, you are done and have a perfectly running, activated on Spring, AOSP with the bare minimum needed to run the phone!

Enjoy
