Patched Magisk v23 for Galaxy A21s (A11/OneUI 3)

[cater2]

I have the SM-A215U. I get the impression this method won't work for me.
I have Developers Options, but do NOT have the OEM option in that menu.
Is there anyway to unlock it without that menu item?

If you dont see the OEM unlock
-Disable Auto System Update
-Then desable Automatic date and time (Found in General Management) > then set the time back 14 days
-Connect to the internet
- Go to software update then check for update and wait a long time till it registers the devices on server
- Once it's registered the OEM Unlock should be visible in the Developer Options

then connect phone to pc

It didn't work.
When I select "Download and install,"
it still shows "Security patch level: August 1, 2021" and
"Current version A215USQS5AUG6."

"Last update" still says,
"The last update was installed on September 2, 2021 at 12:43."

Oh, well.
Also, when I checked for update, it didn't take any longer than it normally does, rather quick in fact. I tried going back 14 days AND one full year, same results each time.

You can at your own risk give this link a try, but the service is paid. The A21s is not quoted but you can contact him ... Good Luck

If I am reading it right, this is not a BOOTLOADER unlock issue they are working on.
It is the PHONE UNLOCK from their carrier.

no worries bro that's fine

No, you did nothing wrong. Many people mistake UNLOCK to mean the wrong type of unlock. I've done it, too
There are two kiinds;
Unlock the PHONE from the CARRIER.
AND
Unlock the BOOTLOADER.

I'm sure you know, WE are looking to UNLOCK the BOOTLOADER.
And I'm sure, in time, someone WILL figure it out.
Adios!

Patched Magisk v23 for A21s (A11/OneUI 3)​

Since I've seen and tried installing Magisk via the default instructions from the legend topjohnwu himself, I noticed it does not work at all. The phone
just doesn't even boot into Android at all, and after researching I have seen that this is a very specific problem with the phone itself due to weird implementation from Samsung.
Extremely simplified, apparently there is a conflict with skip-initramfs because of System-as-Root and the A/B system partitioning introduced with Project Treble. I will still have to read more into it.

There are already patched Magisk apps/images for this phone available, but I noticed they are not really in active development (last patched Magisk was still v22), so I pulled the latest Magisk from the official repository and implemented the fix from this pull request on the official repo. They are not interested in accepting the pull request, so we'll have to do our own "Magisk" for the time being.

I will try to update this as much as possible and try to incorporate fixes, user feedback and more. This has been only tested on latest A11 and OneUI 3. I will also start working on TWRP soon.

Since the APK isn't signed yet, please uninstall Magisk Manager if present, and install this one. It will display a warning when installing, but don't worry.

Options to install:

• Flash boot.tar from the ZIP in Odin on AP
• Install the APK from this thread and patch your own boot image

Is this way will work for Samsung M12... It has the same processor exynos 850

I unrooted my device bro , because after rooting my device, the device was lagging badly sometimes the system ui was getting forced stop automatically, and the main reason i unrooted was that, my banking apps was not running because the magisk was showing safety net failed, I did every thing possible to correct it but it always got failed. And finally my knox got tripped .
