I've been reading online that some people are receiving an error message similar to this:
ddi : mmc_read failed
ODIN MODE (HIGH SPEED)
PRODUCT NAME: SM-N910T
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Official
REACTIVATION LOCK: OFF
KNOX WARRANTY VOID: 0x0
QUALCOMM SECUREBOOT: ENABLE (CSB)
AP SWREV: S1, T1, R1, A2, P1
SECURE DOWNLOAD : ENABLE
UDC START
If so then there might be hope because I was able to successfully make my Note 4 go from a paper weight to a fully working phone. Aside from the error message in DOWNLOAD MODE there were multiple times where I had to remove the battery and place it back in because for some reason the phone wouldn't power on unless I did just that. I'm going to try my best to replicate what I did so that someone else can benefit from this.
