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_S908xxxxx.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_S908xxxxx.tar.md5 and select it. You can have a cup of coffee if you like when you waiting for the patching of the file.

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_S908xxxxxxxxxx.tar.md5

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

-Click on CP and select CP_S908xxxxxxxxxx.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.



How to update system without losing root and data?

Download new firmware of the phone and update the Magisk App if it is not up to date. Unzip the firmware you download and transfer the AP file to your phone. Patch your AP file and transfer it back to your PC (in /sdcard/Download)

Power off phone and reboot to Download mode


Open Odin and put new magisk_patched file in the AP slot, the BL and CP from your new firmware into their respective slots and importantly *HOME_CSC* into the CSC slot.

Press start and let Odin do it's stuff.

When flashed, do not wipe.

Press and hold Vol-down and Power
As soon as screen appears, let go of all buttons.

Within moments without any further user intervention your phone will reboot into your updated Magisk rooted mode, data intact.

I flashed my S22 with SM-S901U1 (XAA) US unlocked firmware. My phone's model number changed from U to U1 which is what I wanted, but my service provider software version is still VZW/VZW,VZW/ VZW. Did I do something wrong? The verizon bloatware is gone, and it boots up without Verizon's load screen, but I'm pretty sure the VZWs are not right except for the last one.

Edit: Could this be because my phone is still carrier locked? And once it is carrier unlocked by VZW I can flash it again?

Your model of your phone will never change because that's your model! (Of course you change it by some way, just the display)

    I, too, am a noob, but I believe having safety net passed is important if you want banking apps, or any app that uses confidential data. Safety net is used to keep your device from downloading harmful apps, and keeping your data safe. So in general some apps might not work if your device doesn't pass safety net.

    Edit: oh you're talking about the original post. Yes, its only showing Non US variants but it's the same process for flashing firmware.

    Thanks

    Is there any way to bootloader unlock a VZW S22 for flashing Treble based ROMs?

    With the Pixel 6 being so massive the S22 is looking awfully appealing... If only I can get it close to the pixel experience.
