Samsung Galaxy A11 in boot loop after root attempt - General Questions and Answers

I hope you guys can help me with this one,
I followed the guide on Magisk website: https://magiskupdate.com/root-samsung-galaxy-a11/
Everything went well up until the final step which is titled: "Re-installing the Magisk App". This is right after I've flashed the patched boot image which was successful, I then proceeded to reboot the phone into recovery mode to reset to factory default and now I get the Samsung logo when I boot the phone, I get the alert that I'm not running official software and then it just loops through the boot sequence again and again.
I tried flashing the boot image again and again but without success.
Did I brick it? Can it be salvaged?
Thanks!

Re-flash phone's Stock ROM to get rid off of all modifications you applied so far.

You haven't unlocked your bootloader, that is why you are getting the alert that says you are not using official software. You have to unlock your bootloader before you can successfully flash a Magisk patched boot.img, it doesn't work on devices that have a locked bootloader.
As stated by the member that posted above me, flash your stock firmware to fix what you have corrupted. Then start over by finding a way to unlock your bootloader, once unlocked, you can try flashing the patched boot.img again. If you cannot find a way to unlock the bootloader, you will not be able to successfully flash and boot the patched boot.img.

Moto G 3rd Gen Stuck on Bootloader unlock screen after flashing root

I finally decided to root my today and after making sure everything worked before flashing the root zip (Bootloader unlocked, recovery installed etc.) I was able to start up and restore my stuff so then I reboot back into recovery to flash the zip (https://download.chainfire.eu/921/SuperSU/UPDATE-SuperSU-v2.65-20151226141550.zip) then I reboot system and now I'm stuck on the bootloader unlocked screen. I can get to fastboot mode right now but I still cant reboot to android.
Edit: Now I am stuck at the boot animation and if you need it my model is xt1540.
I fixed it please delete or lock thank you.

Enter in recovery mode and restore the backup to revert the changes. Then flash SuperSU but the version 2.62-3. Versions above don't work yet.
Thank you I actually got it fixed earlier by flashing cm12.1 but I'll defaniently keep this in mind.

Tried to flash stock firmware to Moto G, stuck in bootloop

After a failed attempt to install SuperSu, bricking my Phone, I'm attempting to flash factory firmware I got from this thread here (Firmware I'm trying to flash is Bell Canada btw). I failed to root using the Windroid Toolkit, and I tried to flash using this tutorial.
After issuing adb commands to flash the files to my device, I rebooted it, only to find out that it is stuck in a loop (Shows Bootloader Unlocked warning, black screen, Bootloader unlocked warning again followed by an animation of the android mascot, with "Erasing" at the bottom of the screen, followed by a black screen, then followed by the start of what I just described").
What else should I try?
Thanks in advance.

At this point I would just flash TWRP and a custom ROM... or if you are set on stock, boot TWRP, wipe everything, reboot to bootloader and flash the factory images again.

Alright, thanks for your advice. I'll try it in the Morning.
EDIT: I followed your advice, and now my Phone is working now, running Resurrection Remix. Thanks for your help!

XZP Wont Boot after Flashing Standard Rom

Hi All,
I've been trying to install TWRP, Root etc on my XZP since yesterday. I've done something wrong at some point, and now my phone will not boot at all.
I had no troubles unlocking bootloader, installing TWRP etc initially. I then tried to install a custom rom from these forums and that's where things spiraled downwards for me.
As part of that procedure, I needed to flash the latest sony firmware first. That went fine.
However, now TWRP is not able to decrypt storage, so I'm not able to flash anything else. Perhaps this is because I booted into the new sony firmware and forgot change the pattern/fingerprint to pin/fingerprint.
So I'm not able to unlock the storage via TWRP by entering a password.
I tried to reflash the same firmware again using newflasher. But the phone won't boot at all. It turns off immediately after the Unlocked bootloader warning. It's not going into a boot loop. Just turns off.
I then tried to flash the TWRP recovery image using adb fastboot command, and the flash seemed to execute properly, but I still can not boot into recovery.
Is it possible the main storage is still encrypted, so nothing can flash to it? Bricked? If so, how do I proceed?
I read something about reformatting partitions? But I'm not able to get into TWRP recovery menu to do this.
*EDIT: I reflashed trwp recovery image, and am not able to boot into recovery. I still can not unlock (unencrypt) the main storage though.
*2nd EDIT: I followed the instructions here:https://forum.xda-developers.com/android/general/how-to-fix-unable-to-mount-data-t3830897
I was then able to flash the stock ROM back onto my device, and I'm able to boot my phone up. I'll look at installing a custom ROM at a later date.

Stuck On "Bootloader is Unlocked" Message On Startup

My 7 pro is rooted and hasn't had any problems prior to this. I updated to the latest OOS version a few days prior to this happening (using twrp retainer script and installing magisk to inactive slot.) The only other recent thing I can think of is that I updated my AdAway host file.
Either way I can't get into the OS proper anymore, it stays on the "your bootloader is unlocked and software integrity cnnot be guaranteed yada yada" screen before going to the bootloader menu wher eyou can choose start, power off, or recovery or restart bootloader. What happened? What can I do?
Update:
After looking at some other threads I saw something about switching the boot slots. I switched from Slot B to Slot A and got past the "bootloader is unlocked" image, but it got stuck on the boot animation. The animation was also slower than normal. What should I do? Please advise.
Reinstall the full ota via twrp, reboot to twrp, reflash full ota, reboot to twrp, reboot system. This should solve the issue ok
Is there a guide anywhere on how to do those things? Will this unroot the phone?
Is there a difference between installing ota and reflash full ota?

Just follow instructions above, just add flash magisk zip after flashing TWRP. Retain root.

I'm confused about what he means when he says install the ota, then reboot and flash the ota. Is there a difference or is that just repeating the same step? He also didn't say anything about flashing TWRP; when would I do that?

Question Unroot OP9 back to stock

I rooted OP9 T-Mobile with a patched boot image of C17. Using fastboot boot patched boot.img. Then direct installed in Magisk.
I need help converting back to the stock firmware. I no longer want root and want to update the phone when updates are released. I uninstalled and restored images in Magisk and tried to take the C18 update but I always get installation error. I then factory reset the phone but still can't take an update. If I try to lock the bootloader I end up on a screen that has red writing saying it can't boot to the ROM for some reason.
Any help would be appreciated. Having a hard time finding the T-Mobile stock or how to install it, if I flash it out how to do all this
