OneUI 4 Beta Update Link - India (Beta 2 Update is live - Dec Security Patch)

Search This thread
This update takes the beta from ZUK1 to ZUKA and has the 1 December 2021 security patch included. Just under 700Mb. Working 100%. Installed and tested.
Can I do a dirty flash from Beta 1 with this version ? Update via SD card with the renaming of the file on "update.zip" ?
Just to be sure ! :)

I flashed beta 2 (after 1) serveral times and each time I lost cell reception. Had to revert to older firmware via Odin. Beta 1 was fine apart from absolutely diabolical battery life. Anyone else experience this ?

OK, so I'm currently in RSA (Republic of South Africa) with an Unlocked SM-N986B/DS (DS - Dual Sim Version).

My CSC was XFA (From OXM) and as on XFA, I did not had the latest November Update which is prerequisite, I changed the CSC to BTU via SAMKey.

As soon as I changed the CSC; XFA to BTU, I checked the update in Software Update and Voila!! I got the new November Update, I updated and I already had BETA 1 from the 1st post in memory card so reboot to recovery and updated from SD Card. And to my surprise it did not wiped my data.

Now I've 14 Credits left on SAMKey, if anybody wants my help please send me a direct message here, this is a help, I wont charge anything for this, but yeah Donations are welcome.

Please make sure you have TeamViewer, SAMKey and Samsung USB Drivers Installed before contacting me.

Thanking everybody who helped in getting OTA Links and the step by step guides, everyone involving in this scene.


Edit - I'm just helping, no fees or anything charged. Donations are highly appreciated.

Anyone get any lag / stuttering in the app drawer on Beta2? Beta1 was lovely an smooth, finding my device very choppy / slow and laggy on BETA2
Yes, I have the same issue as well, dirty flashed over beta 1 . I will try clearing cache / maintenance and restart again.

Edit: After clearing cache and reboot, the phone is now lag-free.

I occasionally seem to get a blank screen when turning the phone on from standby. Only the home and back buttons appear, but do nothing. I find turning the screen on and off usually fixes it after a few tries.

(I'm on a "clean install", that is using the update.zip then doing a full wipe.

Yea I sometimes get this, using Nova. App drawer becomes very laggy. Not sure if it's going into 60Hz mode, or just lag.

    Prerequisite to flash beta on N20U (N986B) thanks to


    You need to be on November Security patch before moving ahead.

    Dial *#1234#
    If your info is ditto same as said below then only you can flash beta 1 for N986B

    AP : N986BXXS3DUJ6
    CSC : N986BOXM3DUH5
    CP : N986BXXS3DUIF

    Also if your device is rooted/modified, it will fail. (unlocked bootloader isn't issue but firmware must be complete stock)

    TLDR instructions, thanks to pernodpepper

    0. Create backup of your device (SmartSwitch) :)
    1. Download .bin
    2. Rename update.zip
    3. Place file on SDCard
    4. Go to recovery (No odin/download mode required)
    5. Select Apply update from SDCard and choose update.zip
    6. Profit

    Detailed instructions along with multiple methods to install. Thanks to Evil_Smiley_za and @AhmedMomen


    This thread will be for sharing tips and help and update.zip/.bin files (when/if available) for the OneUI 4.0 Android 12 Beta for the Galaxy Note 20 series (Unlocked/Exynos)

    Installation Methods:


    1. Download SDK platform tools https://developer.android.com/studio/releases/platform-tools
    2. Extract the file in your desktop.
    3. Inside the extracted folder put the update.zip file
    4. Inside this folder, holding left shift, right click the mouse and select "open command prompt here". The command prompt will open.
    5. Shutdown your phone and connect it to the pc
    6. Holding Power and volume+ and enter into recovery mode.
    7. Select "update via ADB". (scroll down using the volume buttons and select using the power button).
    8. Connect the phone to a PC using an original samsung USB cable.
    9. In the command prompt run the following command:
    ./adb devices
    10. Wait to see that the daemon has started and that your device is found.
    11. If you device is found, run the following command:
    ./adb sideload update.zip

    SD-card method:

    1. Download the bin file and rename it to update.zip (by going to file options on your pc you can select to view the file extensions. This makes the renaming process much easier and safer, and avoids renaming the file to update.zip.zip)
    2. Copy it to the root directory of your SDcard.
    3. Shut down your phone.
    4. Connect any USB device to your device, AKG earphones could work, then press Power and volume+ buttons to get into recovery mode.
    5. Using your volume keys navigate to "update via sdcard" and press power button to select it.
    6. Again using volume keys navigate to the file "update.zip" and press power button to select it.
    7. Update will start. Leave it till it completes installing. It will take some time.
    8. Phone will reboot by itself and load android.

    The update process will start. You will see a percentage counting. First it will verify, then patch etc. Do not move the cable, disconnect the phone or power off the PC.
    Once the process is completed (it takes some time) the phone will boot itself, update the apps and log into your home screen.

    There are two methods that you can use to get into recovery mode

    Method 1
    1. Connect your phone to your PC (Make sure USB debugging is on).
    2. Using ADB, enter the command ./adb reboot recovery
    3. Wait a little and you should be in recovery mode.

    Method 2:
    1. Power off your device
    2. Connect your device to a PC or use the AKG earphones.
    3. Hold down Power+VolumeUp buttons and keep pressing them until you enter recovery mode.

    This will not trip knox if done by the methods above

    Don't install a beta unless you are fully aware what you are going into.

    Don't install the beta if you want your phone to be stable, IT'S a BETA.

    It's recommended to make a backup of your data before updating to the Android 12 Beta.

    Important Notes:
    -Rename the .bin file to update.zip in order to be able to flash it from recovery.

    -A common mistake done by some people is that they see the file named update while its a WinRAR.zip file already, then they add another .zip making the name of the file update.zip.zip which will not be flashed successfully, So make sure you do it right.

    -Updating to the beta is AT YOUR RISK, No one is responsible if anything goes wrong.

    You will not receive OTAs again UNTIL you are on a firmware that gets released later for your original CSC, thats most likely not happening before the BETA is over.

    If anyone knows where to get the beta 3 for sm-n986b 😄 do share with us 🙏🏼🤙🏼
    there is no Beta 3 at the moment. I'm checking multiple times a day and will share when it gets out. Looks like we will get the stable version now considering the fact that Fold also got the stable version recently.
