there should be 5 files when you download the firmware, BL.. CP..AP..CSC and HOME. AP has to be patched through Magisk for root and use HOME to keep your current set up.

    Code:
    Your warranty is now void.
    If you root your device, Your KNOX status will be tripped.
    You can still pass the safety net after you root if you follow the instructions.
    I am not responsible for bricked devices, dead SD cards although it is not really possible
    Please do some research if you have any concerns about doing this to your device

    How to flash official firmware? (not the root and unlock bootloader part!)

    You will need:

    A Galaxy Z Flip 3 and common sense

    Samsung Odin (the flashing tool of the official firmware)

    https://dl2018.sammobile.com/Odin3-v3.14.1.zip

    You need to extract the zip file and you are going to use the file Odin3_v3.14.1.exe inside the folder.

    Samsung Android USB Driver for Windows


    Double-click and install the exe file.

    Samsung Official Firmware


    Download the platform you want to download to. (Windows)

    You need to extract the zip and double click open the file Bifrost.exe inside the folder.

    You need to fill in the Model, Region, press the Check for Updates button and the Download button.

    How to find the Model: on your phone → Settings → About Phone → The third row says the Model number and you need to remove the part with the part of /xx, for example, SM-F711B/DS and you only need to type SM-F711B

    How to find the Region: You can check the Region at this link https://samfrew.com/model/SM-F711B/

    You need to find find a three-letter word (CSC) depending on your carrier and country and type it in Bifrost, for example, EVR

    Press the Check for Update button and download it with the Download button.

    Put it to a place you can easily find, ie. Desktop.

    After downloading it, find the file SM-xxxxx_x_xxxxxxxx_xxx.zip.enc4 on the place you put it and change the document format from .enc4 to .zip. Then, double click and extract the file.

    Open Odin3_v3.14.1.exe and turn off your phone. Connect a side of your USB to your PC/Laptop, keep pressing volume up and down together until you go to Download Mode. Put another side of the USB into your phone. When you arrived at Download Mode press volume up. Go back to Odin3_v3.14.1.exe:

    -Click on BL and select BL_xxxxxxxxxx.tar.md5

    -Click on AP and select AP_xxxxxxxxxxx.tar.md5

    -Click on CP and select CP_xxxxxxxxxx.tar.md5

    -Click on CSC and select CSC_OMC_xxxxxxxxxx.tar.md5

    Press Start to flash the firmware, after done, your device will automatically reboot to the system.

    How to unlock the bootloader?

    Go to your phone → Settings → About Phone → Software information → Press Build number 6 times until you see the notice “You’re now a developer”

    Go in Settings → Developer options → enable OEM unlocking

    Power off your phone first. Then, connect a side of your USB to your PC/Laptop, keep pressing volume up and down together until you go to Download Mode. Put another side of the USB into your phone.

    When you arrived at Download Mode, long press volume up until you see the black screen. Confirm to unlock the bootloader and you will erase your device.

    How to root your phone?

    After you unlock your bootloader, you set up your phone and make sure you do not sign in google account first. Install Magisk https://github.com/topjohnwu/Magisk/releases/download/v24.1/Magisk-v24.1.apk on your phone. Oh yes, in case you do not know, you need to allow the app to install apps so that you can install the apk.

    Transfer AP_xxxxxxxxxx.tar.md5 in the firmware you download from your PC/Laptop to your phone.
    Open Magisk on your phone and press the install button in the Magisk column. Select 'Select and Patch a File', 'Let's Go' and find the AP_xxxxxxxxxx.tar.md5 and select it. You can have a cup of coffee if you like when you waiting for the patching of the file.

    After finishing the patching, you need to transfer the file magisk_patched-24xxx_xxxxx.tar in the Downloads folder back to your PC/Laptop.

    Turn off your phone. Connect a side of your USB to your PC/Laptop, keep pressing volume up and down together until you go to Download Mode. Put another side of the USB into your phone. When you arrived at Download Mode press volume up. Open Odin3_v3.14.1.exe on your PC/Laptop:

    Click on BL and select BL_xxxxxxxxxx.tar.md5

    -Click on AP and select magisk_patched-24xxx_xxxxx.tar

    -Click on CP and select CP_xxxxxxxxxx.tar.md5

    -Click on CSC and select CSC_OMC_xxxxxxxxxx.tar.md5

    When it finishes flashing it, it will automatically reboot and you can gain root access.

    Optional: If you want to have the safety net passed (most of the banking apps use it), then you need to install the zip
    as a Magisk module in Magisk https://github.com/kdrag0n/safetynet-fix/releases
    How? Go to Magisk → Modules → install from storage and select the zip you downloaded.

    My bootloader is unlocked as previously I had root it and went back to official firmware. Now I want to have root but without losing current data.. 🙃 Thanks
    Flash the Magisk patched AP file in the AP slot and the HOME CSC in the CSC slot, I wouldn't go flashing anything in the USERDATA slot that sounds like bad advice.

    I tried to root my phone following this steps (twice) but it didnt work. I finally made it using the 4 files, included magisk patched AP, and csc file (not home csc). Unfortunately I got rid of the root cause I couldnt connect my smartwatch. In the past I downloaded modules from magisk manager to access my smartwatch. This time I couldnt find the magisk link to modules. I cannot live without my watch so bye bye root. :cry:
    there is a new app for us to access the magisk modules repo
