OTA and Non-OTA Firmware for N986U and N986U1

Search This thread
Let me know what your trying to do i still have my AT&T Note20 Ultra 5G Snapdragon 512GB as my backup phone.
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.

I have a u1 that is a snapdragon variant that i got from Google store for use with Google fi. From what i have gathered it is a tmobile u1 variant. It looks like all the roms for u1 are exynos roms, and all the t mobile roms are non-u1 roms. Help? I just want to update but i lost my original fi firmware when i soft bricked my phone.

U/U1 versions are US based and they are both snapdragon, U1 is the us unlocked and the U is the carrier locked. You can flash either or.
 
The fw name translation in the op says snapdragon roms should be xxxxxxxSQxxxxxx while the ones listed on the u1 section are xxxxxxxUExxxxxx. Doesnt that mean the ones listed there are for exynos?
Not sure what UE means to be honest but knowing that Exynos is not existent in the US models and U1 and U are both US models you are safe to flash these (knowing that your device is either of those models).

Hi.

Would I be able to use this to downgrade my phone, ultimately enabling OEM bootloader unlock, and root?

I am currently on One UI 4.1 Android 12.

TIA

Depending on your bootloader version that probably is the 2, you can downgrade to any firmware with the same version not bootloader 1 if that makes sense.
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?

    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 😁
