2. Extract the file in your desktop.

3. Inside the extracted folder, put the update.zip file you downloaded.

4. Inside this folder, holding left shift, do a right click with the mouse and select "open command prompt here", The command prompt will open.

5. Shutdown your phone and connect it to your pc with an original cable

6. Holding power and volume up buttons, 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+volume up 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 connect the AKG earphones.

3. Hold down Power+VolumeUp buttons and keep pressing them until you enter recovery mode.

How to capture the update.bin file to share with other people:

1. Download HTTP canary app from playstore

2. Open HTTP Canary app

3. Leave the app and go to the settings and Start the software update in settings by pressing "download" and don't pause it

4. Go back to canary app and start it by pressing the little circle at the bottom right, and it will grab the link for you

5. Copy the link and post it here if you wish.

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.

Small note:

My Galaxy S20 Ultra isn't from a country that has a beta program, I manually changed the CSC to DBT, that makes me receive DBT OTA Updates but participating in the beta in the past years, needed a sim card from the country of your CSC, Meaning i need a german SIM to be able to participate, so sadly i will not be able to pull the update.zip file unfortunately, But i will try my BEST to keep the thread updated with the latest beta update.zip file (If/when someone pulls it)
