What's knox ? : https://www.google.com/search?q=samsung+knox+explained

-Download the latest stock firmware for your Samsung Galaxy A51 with Samfirm/Frija app (faster) or Samfrew/Sammobile website (way slower).


https://samfrew.com/model/SM-A515F/


-Extract the SM-A515XX_1_EXAMPLE_0000000000_fac.zip file with 7zip or any other unzipper.

-Copy the (AP_A515XXXXU1XXXX_CL00000000_QB00000000_REV00_use r_low_ship_MULTI_CERT_meta_OS10.tar.md5) file and transfer it to your internal storage.

-Download and install Magisk Manager APK https://github.com/topjohnwu/Magisk/...ger-v7.5.1.apk

-Open Magisk Manager and go to Install > Install > Select and Patch a file.

-Navigate through the storage and select the extracted AP file.
The firmware will be patched and will be found in Internal Storage/Download/magisk_patched.tar.

-Transfer the patched file to your PC.

-Turn OFF your device and boot into DOWNLOAD MODE.

-In Odin, click on AP and select the patched tar file, Uncheck “Auto Reboot” and click on Install.

The tool will flash Magisk V20 on your Samsung Galaxy A51.

To boot in recovery or boot the system with Magisk installed:

1. Powering up normally → System without Magisk
2. Power + Volume Up → Bootloader warning → Release all buttons → System with Magisk
3. Power + Volume Up → Bootloader warning → Keep holding volume up → Actual recovery

Hi,

When unlock bootloader samsung and in the future I wanna back to stock firmware and re-lock the bootloader, is it still can get OTA update ?

I have experience with Asus Zenfone 5 2018, when I unlock bootloader and back to stock firmware & re-lock the bootloader. even in locked bootloader, phone cant get OTA update again. I must install manually from .zip installer.

Thank you.

Did you checked the root method ?? currently there is blocking point

there are two Vbmetas (Vbmeta.img,Vbmeta_samsung.img ) a different solution/patch is needed (twrp or magisk or both) in order to root this device.
