[Samsung Galaxy A51 5G Guides, News, & Discussion] BredzProh:
One UI 3.0 beta has been released for Galaxy A51 5G.

If you are part of the supported regions, you can grab the update link and share it here (for each update).

These are the steps I borrowed from @AhmedMomen 's S10 thread.

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

1. Download HTTP canary app from Play Store.

2. Open HTTP Canary app.

3. Start the update by pressing "Download". Don't pause it!

4. Go back to Canary app and start it. It will grab the link for you.

5. Please share the link and your model number here!

As for how to sideload the update.zip file, I have explained it step-by-step here:

ADB Method:

1. Download and install adb.

2. Connect your phone to your PC.

3. Download the update file where you have installed adb Platform Tools.

4. Rename the file (including the extension) to "update.zip". Click "Yes" on the prompt.

5. Open your terminal of choice.

6. Type "adb reboot recovery" and press ENTER on your keyboard. Wait for your phone to reboot to recovery mode.

7. Navigating with the volume buttons and selecting with the power button, go to "Apply update via ADB".

8. Back to the terminal on your PC type "adb sideload update.zip". (NOTE: If it says that device is not connected, just remove and put the USB cable back until it works).

9. The update is being installed. It will be completed when the phone boots up. You may use your phone normally after.

10. Report any bugs on the Samsung Members app! https://www.samsung.com/global/galaxy/apps/samsung-members/

SD Card Method:

1. Search for an update file. You can usually find one in XDA Forums.

2. Check if you have the right build and open the right link.

3. Download the update file (.bin extension).

4. Move the update file to your SD Card. (NOTE: If you are getting errors, back up the stuff of your SD Card and format it from your Galaxy phone.)

5. Rename the .bin file (including the extension) to "update.zip". Click "Change" on the prompt.

6. Reboot to Recovery Mode, by connecting your phone to another device (such as your earphones) and holding the Volume Up + Power (+ Bixby) buttons.

7. Navigating with the volume buttons and selecting with the power button, go to "Apply update via SD Card".

8. Navigate to and select "update.zip".

9. The update will start installing. It will be completed when the phone boots up. You may use your phone normally after.

10. Report any bugs on the Samsung Members app! https://www.samsung.com/global/galaxy/apps/samsung-members/
