The OTA is not broken if you flash out of order. Sometimes yes but not always its hit and miss. I have flashed versions that At&t did not release and still got OTA. But yes you are on point this does happen.

I'll try to keep on top of the various different firmware releases for each of the carriers. AT&T and Verizon can be a real pain because they don't release the firmware. So most of the time we'll have to "cross check" their new update to an TMB/SPR/USC release.


N986USQU1ATH4 LINK USC/TMB/SPR - Thanks @Venom0642
N986USQU1ATH3 LINK CCT
N986USQU1ATGM LINK - SPR/USC/CCT/TMB. Thanks to @butchieboy for starting us off
N986U1SQU1ATH3 ATT Unlocked LINK Thanks to [MENTION=4496829]butchieboy




Odin3_v3.13.3b: HERE
Odin3_v3.14.4: LINK


When I download ATT I am getting "N986U1UEU1ATH3" Is this correct link?

Info on how to do this is everywhere. Are you sure you want U1 firmware? You mention not caring about bloat. People usually flash U1 because it has less bloat.
U1=Unlocked firmware
U= United States firmware carrier specific. And not trying to be a jerk, I just don't understand why so many buy U device but then want U1 firmware. Why not just get the U1 device? Just curious

I got $1000 credit from att by switching to them and trading in my old device, I also get att discount through my employer. I would have bought unlocked if I could but this was a good deal for me, better than paying 1300 out of pocket.

Will that break ota?
I notice you flashed U1. So which ota are asking about that will be broke? Are you wondering if you will still get ota on U firmware since you flashed U1 to your locked device? If that is what you are asking why not just stick to your U firmware if your concerned about getting ota. I think a ton of confusion is coming in because someone asked about unlocked firmware. I figured I would offer it up to help him out. Some are now flashing this and that without understanding the basics of the firmware and how to flash.

I know how to flash, I'm asking if flashing the u csc file to get wifi calling will break ota.

It's not a deal breaker for me, I can live without wifi calling. I rather have faster updates and probably will flash again when 3.0 drops. It was just a question since you're more knowledgeable in the subject.

    I just flashed the latest U1 build to my ATT U, and it flashed correctly, I got the unlocked version features like the integrated spam call blocker. Now in settings it still shows ATT/ATT/ATT, did I make something wrong? I wanted to get the full unlocked experience and just use the att network. Also I'm seeing that my 5G icon is the ATT branded one.. So I'm kinda confused. Flashed the csc partition and not the home csc.
    Not sure if someone already answered this and sorry to all my amazing friends here that i am not able to be online as often. Hope you all are doing well.

    So your ATT/ATT/ATT lets represent it as 1/2/3 - Now /3 is something you can not change - so if you bought from ATT it will be 1/2/ATT if from T-mob it will be 1/2/TMB - So that always remains same.
    for 1/2 it depends on the sim card you insert, it seems you are using ATT sim. I have unlocked version so my /3=/XAA , as stated above it remains same regardless of sim i insert, and i am using TMB so my 1/2 = TMB/TMB if i was using ATT it would look like ATT/ATT/XAA. Hope this answers your question.

    Ok, so I did get really bored and flashed U1. To be 100% honest if you put the device in front of me with Carrier/Unlocked firmware, I couldn't tell the difference. Aside from the bootscreen animations and actually looking in the actual firmware revision I genuinely can't tell ANY difference.

    Please take a look at the OP, it'll answer that for you :)
    embarrassing! Not at the top easily available to everyone. Sorry for not reading. The best place to hide things from me is right in front of my face.

    See Post #2 and #3 for the Links to the Firmware
    ALL of the firmware posted here can be flashed on any N986U/N986U1 Device. The firmware is NOT carrier dependent and is only listed next to some of them in order to have an idea if you might get OTA when you flash it

    Understanding Firmware naming:

    N986USQU1ATGM
    N=Note
    986U or F etc, the model of device
    SQ, FX etc = CPU and model specific
    U,S,E = Update, Security, Engineering, respectively
    1,2,3,4,5 etc = bootloader revision (This is important! You cannot go to a previous revision)
    A,B,C,D = Android version
    T, U = Year (T=2020, U=2021 etc)
    A,B,C etc = month (January A - December L)
    1 - 9 and then A - Z =build compilation. This basically means how many builds there are in a month. They start at 1 and go to Z
    So N986USQU1ATGM would be
    N968-U-SQ-U-1-A-T-G-M
    N968U (Note 20 Ultra Carrier version), SQ (Snapdragon), U (Update), 1 (Bootloader version), A (Build 10), T (2020), G (July), M (22nd build)

    How to enter Download Mode:
    Turn off the device.
    Connect USB cable to your PC (Leave it disconnected from the phone)
    Press and hold down the Volume Up and Volume Down buttons. While they are still pressed, plug in the USB cable into your phone.
    The phone will go into download mode press volume up. In Odin you will see that phone is added.

    Dirty Flash:
    I would only do this if you are having to manually update to the newer firmware and would not do it if you are coming/going to U/U1 or from beta firmware or if you are on an old firmware. I'd also highly recommend doing a back up prior to the doing this
    Load these into Odin
    BL
    AP
    CP
    HOME_CSC
    Do NOT flash CSC or USERDATA, either of these WILL wipe your device
    This is a "dirty flash" and these can sometimes cause issues. Keep in mind if things start going sideways and stuff starts not working right, your first step to a solution will be to wipe the device.


    Tips on flashing U1 Firmware:
    Thanks to @mm60 for being the guinea pig and doing the base write up

    Flash the U1 firmware, which you can get on Frija. Make sure you use the patched ODIN linked in post #2, Odin3_v3.13.3b.
    Boot up the phone with an active US Carrier SIM installed.
    Go through the initial setup and connect to Wi-Fi.
    When the pop-up saying that the phone "needed to apply carrier settings and reboot", agreed and let it reboot.
    Once the phone reboots, go through the setup and verify the Service Provider is your carrier (VZW/SPR/TMB/ATT, etc) is in the Settings.
    Flashed the U firmware again with the USERDATA file and set it up again (The USERDATA file is Carrier agnostic. The carrier features/apps will be installed based on the active carrier SIM that's installed when it's flashed)

    If you get your CSC Stuck on XAA/XAA/(Insert your carrier here), and can not get Carrier options back.
    Go to the tutorial that @borijess put together HERE
