Can't flash stock firmware with Odin

It's been a long day... Let me start by saying that i had my device rooted for a month without any issues. Last night, i noticed some apps were killing themselves for some reason but i didnt give it much thought. This morning while i was working, i noticed the phone app was crashing and not responding, so i decided to restart it. It ended up getting stuck on the T-Mobile boot screen. I tried to boot it into recovery mode, but it wasn't the normal recovery mode. It didnt give me option to scroll up and down with the volume keys. It's just a black screen with:
RECOVERY BOOTING......
ODIN MODE (HIGH SPEED)
PRODUCT NAME: SM-G935T
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Custom
FRP LOCK: OFF
WARRANTY VOID: 0x0
QUALCOMM SECUREBOOT: ENABLE
HP SWREV: B3(2,1,1,1,1) K1 S2
SECURE DOWNLOAD: ENABLE
It just stays on this screen until i power the device off, and it goes right back into a bootloop. Also, i can't boot into safe mode either.
So, I figured I would try to flash the stock firmware with Odin. I downloaded the firmware and tried to flash it and got this error:
Added!!
Odin engine v(ID:3.1203)..
File analysis..
SetupConnection..
Initialzation..
Set PIT file..
DO NOT TURN OFF TARGET!!
Complete(Write) operation failed.
All threads completed. (succeed 0 / failed 1)
I did some searching and found that i might need to flash a .pit file, so i found the one for my device and put in in Odin. I tried to flash it and got this error:
Added!!

File analysis..
SetupConnection..
Initialzation..
Set PIT file..
DO NOT TURN OFF TARGET!!
FAIL!

Re-Partition operation failed.
All threads completed. (succeed 0 / failed 1)
At this point, I have no idea what to do or try. I need my phone for work and ive already missed today. If anyone has any advice, it would be greatly appreciated!!!!!
