OTA and Non-OTA Firmware for N986U and N986U1

Search This thread
USC has july update as well. But what bloatware comes with USC firmware.
Not sure what bloatware that comes with if your phone is with USC, But if you on a carrier then it will do the bloatware for that carrier doesn't matter what firmware you would install, the sim card is what triggers the carrier bloatware on any firmware for that particular device.

If it was a substantial update I would consider going to U but just for security patches no way. I'll just wait. Maybe Samsung will remember about the unlocked N20U soon lol.

They must be working hard getting that One UI 4.0 beta ready for us. ;) (just kidding)

Meanwhile still no July update for unlocked N20U. I'm thinking at this point maybe our next update is 3.1.1. That's just a guess on my part but Samsung has been very good with updates so it is odd it is taking this long for one of their flagship units. They must be focusing their attention on 3.1.1. I could easily be wrong though lol.

    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
    Thank you so much for this step by step instruction. I flashed from U1 to U & moved my # to esim w/o any issues whatsoever. So nervous before starting & now so excited b/c I'm able to use phone for my 2 lines (1 from TMO & other from VRZ).
