How do I check my current bootloader version?
I can't find the note20 ultra snapdragon root guide anymore. I could've sworn I saw it somewhere. Have you seen it?
So as far as im aware only bootloader v1 was unlockable, and then it was only unlockable by elliwigy from sampwnd (also a mod on xda) for a fee (claimed it cost him money to get the files for unlocking and he wasn't profiting, suspicious to me). I paid him to unlock my bootloader in jan 2021 and he was quick about it, but since then he has fallen off the face of the earth. Other xda mods say they haven't heard anything from him in ages, his website is still up and accepting payments but no one will reach out to you if you pay there and you will not get your unlock. You might be SOL on that root, homie.

Even when you could get it it was hella sketchy. You sent him uuid and something else from your phone then installed a vpn client and a usb over network driver and he odin flashed your phone over network usb through the vpn

Hello,

Sorry if this has been asked before,

I have Samsung Note 20Ultra 5G, unlocked and using it outside US
Model: SM-N986U
AT&T Carrier
Base version: N986USQU1BTIF
Android 10 / UI 2.5
01 Sep 2020 Security Patch.


I may never update the device but since yesterday I am having MIC issue with whatspp and other APPS skype etc voice calls, MIC is working fine on normal calls so its not hardware related issue

I have read post#1 and post#2 carefully.

So I need someone to point me which firmware is best to flash so I can get future auto updates ?
Not interested to keep AT&T APPS but more interested in device stability ?
I will take full backup before flashing to be on safe side and do not want to wipe the device unless its the last option so can I keep personal data after flashing ?

Your firmware is about 2 years old now............ REALLY OLD
The last AT&T factory firmware I have available on this thread is N986USQS2EULI That is from Jan this year, and should help a lot regarding features/security updates. Being as old as yours is I would NOT recommend a dirty flash. Back up and allow it to wipe.
If you want to avoid all of the ATT bloat you could flash the latest U1 I have here - N986U1UE2FVC5 I don't remember if this is an ATT firmware or not

Updated note 20 with N986U1UE2FVC5 and after that it auto update to latest firmware, its service provider software versions says XAA/XAA/ATT/ATT so the firmware was AT&T.

But it didn't fix the issue with microphone, its still not working with whatsapp, skype etc but only works with normal call, I have tried almost every suggestion by searching about problem on google, nothing works, update doesn't work so any suggestion, can it be hardware issue, but how can it be if microphone working with normal calls.

I have N986U ATT/XAA,XAA/ATT.

Can i flash N986U1 ? Will i loose esim frature?
I'm running U1 Firmware & the option is available.
However, I am on T-Mobile, not AT&T. Just taking an educated guess, but, I think you'll be good to go.
At least you can change from U to U1 w/o a factory reset, so, no harm in giving it a shot.

I just bought two Note 20 Ultra 5G phones on ebay from two different sources. They were both in great condition so I was lucky about that.

The first one I got was a N986U model and the other was a N986U1 model. I did all the software updates I could for both. The N986U model got three updates and ended up going from Android 12 to Android 13.

My issue: The N986U1 model only got one update which I guess was a security update because it stayed at Android 12.

Questions:
1) Is firnware OTAs being late a common problem with the N986U1 and other Samsung factory unlocked models?
2) Is an Android 13 firmware OTA just late for N986U1 or is it never coming?
3) Should I send the N986U1 model back and try to get a N986U model?

    Plz help brother
    My Note 20 ultra stuck on Android 12
    It's unlocked at&t
    Model N986U
    I need to flash android 13
    Which one can i flash it
    And if i flash android 13 will lock again on AT&T?
    Sim lock/ unlock is different from firmware and no if your phone is unlocked, then flashing another firmware will not Sim lock it. Please spend time on reading through forums before flashing, it will help avoid issues.

    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.

    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 😁
