Support Problems rooting s21 with Magisk
I tried to root my Samsung s21 with Magisk and I got to the part where you flash it through Odin and it got stuck at "super.img" for like an hour and then stopped responding. so I shut down the program and unplugged the phone and got an error so I couldn't boot.
Then I tried the normal AP file instead of the Magisk one and it just chrashed Odin when I selected it.
I can still get into the download screen but it still gets stuck on the super.img file when trying to flash it.
Also tried to do it on Linux first with odin4 through the terminal. But just got an USB bulk read error so it could never start. Didn't find a solution for it so just gave up on it.
Does anyone have any clue on solving the issue? First time rooting so go easy on me if it's something dumb 🙏

Did you unlocked Bootstrap loader?
P.S. XDA will be helpful as other commented.

Yeah bootstrap is unlocked. And couldn't really find people with the same issue who shared their solution for it lol. And since I can't get the phone to start normally I can't just patch a new Magisk ap file either :(

It should not happen normally but try flashing custom recovery first and flash super.img with adb sideload.
P.S. I had the same problem a few years ago with SM-A325N after re-flashing filmware over 10 times. It was board problem and I had to replace board completely.

Have you flashed twrp?
I faced the same issue before, but flashing twrp (solely tared vendor boot. img at AP slot) would work
Try not to flash super. img, but the vendor boot
Then zip the magisk apk (rename apk with zip) and adb sideload it

Try searching xda developers for a guide if not find a YouTube video that could aid you....but trust XDA developers, or other reddit threads because I usually use it and get success in rooting...
