[T-Mobile Galaxy Note 4 General] dmw_4814:
I'm in DESPERATE need of some assistance, if anyone has any ideas on how to solve my problem.

I had a T-Mobile Galaxy Note Edge that I bought back in December. I flashed TWRP onto it and rooted it without any difficulties, but the ROM I was using on it (Dr Keton; M6 release) wasn't really designed for the Note Edge's curved screen. I had trouble sometimes typing on keyboards like Swype and SwiftKey. I finally had enough, and I bought a T-Mobile Note 4 (I'm on AT&T, but obviously the bootloader is locked on the AT&T versions of these phones), and the problem I need help with is getting ODIN to flash ANYTHING over to the phone, without just "hanging" at some point (without giving any error or anything; it just sits there).

I got the phone in the mail on Friday, and I'm worried I might've screwed myself by downloading a series of OTA updates that took the phone from Lollipop 5.1.1 (I think that's what was on it when I first powered it up) to Marshmallow 6.0.1 (the current version/build is listed as MMB29M.N910TUVS2EQE2; Android security patch level May 1, 2017).

At this point, I'm unable to get ODIN to successfully flash a TWRP recovery or a stock firmware file. ODIN (after I sart and run it as an Administrator) recognizes the phone's been connected to the computer; the "ID:COM" box lights up blue with whatever COM port it's connected to), and when I click on the "AP" box and select my TWRP recovery file ("trwp-3.1.1-0-trlte-img,tar", in this case; I've also tried "twrp-3.0.2-0-trltetmo.img.tar" and "twrp-2.8.7.0.0-trltetmo.img.tar"), then click "Start", the log shows it gets as far as "<ID:0/006>recovery.img". Then, nothing. It just sits there forever (I've left it like that as long as two hours), and goes nowhere - it never proceeds any further, and it never gives me an error message. On the phone, under the green android , where it says, "Downloading...do not turn off target!!", the green progress bar that's supposed to go from the left side of the screen to the right side, it just appears enough so that it looks like a green dot.

The same thing happens if I try to flash my "N910TUVU2DOK2_N910TTMB2DOK2_N910TUVU2DOK2_HOME.tar.md5" firmware file. The ODIN log shows it gets as far as "<ID:0/006>aboot.mhm", then - nothing. It'll just sit there until I unplug the phone, when it then announces "Fail!" in the upper left box (that's the same thug that happens if I unplug the phone when trying to flash the TWRP recovery file).

In both cases, if I reboot the phone back into the Android operating system, the phone boots up completely normally, as if nothing at all was done to it (which is probably exactly the case!).

Anyone have any idea why this is happening, or what I need to do to successfully flash TWRP on my phone and root it? I want to use that same Dr Keton ROM I was using on my Note Edge, on my Note 4. I don't remember having any difficulty at all flashing a TWRP recovery onto my Note Edge, but then again, I don't remember updating it with OTA updates, either.

FYI - I enabled "Developer options" and have checked "Enable USB Debugging". There's no "Allow OEM unlock" option showing.

Any help or suggestions anyone can give me would be GREATLY appreciated! I really want to get this phone set up, so I can start using it and sell my Note Edge!

Thanks in advance,

Dennis
