I'm at my wit's end. I was sent a phone through insurance replacement that's unable to receive OTA updates. It's unlocked but is somehow an ATT version of the Note 20 Ultra. When flashing the latest ATT version of the Note firmware, Odin says that it's a write failed opertion. I'm not sure if I should try to flash another carrier, despite it being unlocked on the download screen it says that the carrier is ATT. I'm using a Tmobile sim card. I don't know if I should give up and get an S22 or what.

Are you using the Odin that's listed in post 2 or 3?
As far as the firmware is concerned there is no firmware specific to any of the carriers. They are technically the same, they install some specific things related to the carriers based on the SIM card thats installed.
If you look in your settings>About Phone>Software Information, what does it say under "Service Provider software version" and What is your Baseband version?

I had to use the patched Odin. My baseband version is N986USQU1ATGP
I'm on Tmobile, but it's unlocked. I think that it's the AT&T version that won't update OTA. I used the latest version of Android from here for AT&T hoping to gain back OTA updates. Well, I can't say gain back, because the phone is still on July 2020 patch. It's never been updated.

I was using the instructions provided on Sam mobile, and only flashing the AP file. I see these instructions on this website, I'm wondering if I wasn't doing a complete job.

Extract (un-rar) the firmware file (i.e. to folder c:\Odin) ***
2. Download Odin v3.14.4
3. Extract Odin ZIP file (i.e. to folder c:\Odin)
4. Open Odin v3.14.4
5. Power OFF your Note20 Ultra 5G
6. Reboot Phone in Download Mode: Connect USB-cable to your computer. Hold down "Volume up" and "Volume down" at same time. While holding down, connect the USB-cable to your phone.
7. Wait until you get a blue sign in Odin
8. Add the firmware files to their designated slots (AP in AP, BL in BL, CP in CP, HOME_CSC in CSC). USERDATA stays EMPTY!
9. Make sure re-partition is NOT ticked
10. Click the start button, sit back and wait few minutes.

If I follow these instructions, I won't brick my phone, will I? It's been years since I've rooted a phone or done any modifications, so I'm not sure if bricking only happens with rooting.

Update, I've done all of this and it still won't flash. It's stuck on the setup connection. I've tried multi builds, none work.

Last Edit

I figured it out. Someone told me to get the CSC and then find the firmware for the CSC a few days ago, and I didn't think that was important because it was unlocked. I had to do that, and once I matched that number, I found the correct build and was able to get it downloaded and working. Thank you for listening to my complaining.

Good, I'm glad you got it figured out

Hi guys, i have issue with software updates on my Note 20 Ultra, since i've bought it. It's still on android 10, one iu 2.5 and i have not released any updates yet. My phone model number is SM-N986U, CSC is ATT, baseband version is N986USQU1ATH3. SM-N986U1 model does not have firmware with bootloader 1 (which is mine) for the latest Android 12, only for Android 11 N986U1UEU1DUB5. Would you help me, please? Witch firmware should i download and install?

It's your choice, you can flash either the
U firmware N986USQS2EULI or the
U1 firmware N986U1UEU2EVA9
These are both the latest versions for AT&T. Since your current firmware is SOOOO old (Aug 2020 kind of old), I would VERY STRONGLY recommend backing up your device and allowing it to wipe data

These both will update your device to Bootloader 2 firmware. It's not your device itself that has a "bootloader 1" or "bootloader 2", thats a part of the software package

So I have to get it rooted all over again..... PITA seems my oneUI is at 4
I was looking for the thread about how to root, but I cant seem to find it. One of the guys here was rooted, and I THINK he was forced to stay on a specific build because the root method wasn't with the current OTA builds

    Good to know my man. I'm having issues getting 5G+ on my Note 20, I tried everything regarding the network, (i work on an AT&T store and did the troubleshooting, sim card swap, network reset, without luck), only thing I haven't tried is to factory reset the phone. And also I haven't put my hands on another Note 20 U here to test. It was just to see if other users here were getting 5G+ on their note.

    Only thing i get is 5G both phones never seen 5G+ On My AT&T Note20 Ultra 5G Snapdragon 512GB or even my S22 Ultra 5G Snapdragon
    512GB
    I live in Laramie Wyoming so not sure if that's something i would have to test more if going to Colorado Denver.
    Yeah as far as I know, is not as widespread so it might also be that there's no 5G+ in your area yet. If you see something at any time let me know! I would appreciate it.

    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:
    You will have to wipe, can NOT dirty Flash going between U and U1 firmware
    Use the patched ODIN linked in post #2 or #3, Odin3_v3.13.3b (They are exactly the same)
    Have an active US Carrier SIM installed to get carrier features


    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

    Just a little heads up to everyone. When Android 12 drops for U1, I'll be removing the Beta stuff since we wont need it any longer. I try to keep things a little clean and tidy 😁
