I soft bricked my G930FD when going from v14.0 to v15 using the in-app update but got it back by dirty flashing my stock ROM thanks to the help I got here.
Now I'd like to install the latest Magisk to get root back but despite reading a lot of threads where people solved similar issues going to v15 on Samsung devices and following their suggestions, I can't get Magisk to work and always get stuck on boot, either a boot loop, or more often, the pulsating Samsung logo.
If I try using the patched_boot.img.tar method with v15.3, which is technique I used originally to install v14.0, then I get stuck at the the pulsating Samsung logo. If I use TWRP to flash the v15.3 zip, I get a boot loop. At that point, flashing the stock boot.img allows me to boot or if I flash no-verity-opt-encrypt-6.0 then I get to the pulsating Samsung logo. I did select 'Preserve AVB 2.0/dm-verity' in Magisk Manager.
I also tried again with a clean stock ROM install and flashed the v15.3 zip and immediately flashed no-verity-opt-encrypt-6.0, as suggested by someone who'd successfully installed v15.3 on an S7, but again, stuck at the pulsating Samsung logo.
One clue perhaps, TWRP couldn't see the internal SD card data (iow /data). I wasn't able to check this option in the 'Mount' menu in TWRP either. I think this points to /data being encrypted. TWRP could see it before I dirty flashed the ROM, so perhaps I've inadvertently encrypted this. I was careful to uncheck 'Preserve force encryption' in Magisk Manager , which seemed to default on.
I'm at a bit of a loss so would really appreciate it if you can tell me how to get up and running with Magisk v15 on my Samsung Galaxy S7 if you've managed this yourself.
Can anyone share how they've done this?

I've let the MagiskManager upgrade Magisk from 14.x to 1.50. Then I rebooted the phone, and then it was stuck at the pulsating SAMSUNG logo.
So, next step would be obvious: get into TWRP and install Magisk 14.0.
And so I did, and so it failed. This time I got a bootloop. The "Galaxy S7 powered by Android" thing appears for a few seconds, and then vibrates and starts over. And over, and over, and over.
So then, I "installed" the Magisk Uninstaller. Thinking to get rid of all traces of Magisk that introduced this problem in the first place.
So I did, and now I'm back at the first problem: stuck at booting.
Then installing Magisk 14 AND wiping cache&dalvik: boot loop
Then I installed the uninstaller again, then Magisk 15, and wipe the cache&dalvik. And it's back at being stuck while booting again.
Brilliant. What do I do to fix this?
Are you using a custom ROM, or a port ROM, or a custom kernel?
It's all stock, except for it being rooted.
I'm having the same issue. Canadian S7 W8, Stock ROM with root, Magisk 14, upgraded to 15 using direct install through magisk manager.
Yes, exactly that. No offense, but that's helping neither yourself nor me nor anyone else. Have you been able to figure anything out?
Maybe how to produce some kind of log output?...
Same thing happened to me just now. Never would have thought that upgrading through the Magisk app would cause this. I've tried all of the above and have also tried installing v 12.0 but still no dice.
I even tried a factory reset and still no dice. This is seriously infuriating.
Guess I will have to reflash everything and start fresh. If anyone else has any other ideas I'm all ears.
I'd like to know what the phone is actually *doing* when it's stuck. How can we get to know this?
`fastboot logcat` and `adb logcat` both keep waiting for a device that will not connect. Something does connect, christ knows what, but certainly no adb or fastboot device.
@fattyspecial
"reflash everything and start fresh" can you explain what exactly this comprises? What should I do?

Mate 8 running 7.0 stock except rooted, running Magisk 14, did the same thing and I'm in the same boat. Have also tried removing magisk, reinstalling 14 no dice. Have not factory reset yet (trying everything else before that step) but it looks like it won't help.

Completely reflash the entire stock rom with ODIN and then re-root and reconfigure my entire phone. About the biggest bother imaginable.
I'm trying to re-flash only a new boot.img (or new kernel) through twrp right now. If I can get that to work I'll let you know right away.

FIXED IT!
Ok here's what I did. Maybe not a perfect solution but I am out of bootloop and phone is working and root is working too.
I had to install a custom kernel. I'm guessing this replaces the corrupted boot.img file. So you will need to be rooted and have a custom recovery like TWRP.
Go to https://forum.xda-developers.com/galaxy-s7/development/kernel-tgpkernel-t3462897 and scroll down to the part that says: DOWNLOAD VIA ANDROIDFILEHOST for N version and download the zip file.
Transfer the TGPKernel zip to your external SD card (either with android file transfer if on mac like me or with an SD card reader).
Flash the zip in TWRP.
It will take a LONG time to reboot. Don't worry.
I chose to install root with Magisk and it ended up updating it to v15.0 and so far everything seems to be working well.
Hope this helps. That took a long time to figure out. Time for bed.
Ok, I'm still not in that loop... yet.
Ok, I'm still not in that loop... yet.
I selected installing the 15.0 Magisk zip file (from 14.0) using direct install, then did the reboot and I'm stuck at the pulsating SAMSUNG logo.
Can I do the same fix of fattyspecial without loosing anything on the S7?
I did the exact Magisk 15.0 zip update on my LG Nexus 5, with no problem, in less than a minute.
I'm still not in that loop... yet.

If you can' t solve download Magisk Uninstaller https://forum.xda-developers.com/attachment.php?attachmentid=4370032&d=1514240372
and Magisk 14.0 https://forum.xda-developers.com/attachment.php?attachmentid=4264532&d=1504713887
Then reboot in Twrp (hope you have it) and flash
1 uninstaller
2 14.0
I had the magisk 14.5 and I installed the 15 via twrp on top, and it updated normal. Is there a problem updating this way?
@fattyspecial
I don't see why installing a custom kernel is a viable fix. Or a good idea. It seems random.
Maybe you can explain why this is a fix, and how the stock kernel makes the phone bootloop?
@Tribal123
I think you will find I've already tried it. I appreciate your contribution, but please do read my topic start.
Same here, updated from v14 to v15 and got a nice bootloop.
Huawei Mate 8 with Nougat (stock) and TWRP.
EDIT:
Solved!
Flashed my stock boot.img backup through TWRP, then booted my phone and downloaded v14, flashed v14 through TWRP, booted my phone again and downloaded v15 with Magisk Manager app and checked "Preserve AVB 2.0/dm-verity" and then tapped "Install" using "Direct Install (recommended)"

Because a custom kernel disables dm-verity. There's an issue, mainly on Samsung devices, with the dm-verity detection in Magisk v15.0. It's under investigation...
Meanwhile, flash a dm-verity disabler together with Magisk v15.0 and you should be good to go.
I'm fairly certain you need a custom kernel. I'm also on the S7 and without one I've always boot looped, I think it has to do with dm-verity.
EDIT: I didn't notice there was a second page so I guess I didn't really say anything new, oh well, sorry!

Hello,
Here is the problem I personnaly had (solved now !) :
Initially, my wife had a G930F (samsung galaxy S7) and a Custom 7.0 rom (i think it was the "AlexNDR.G930FXXU2DRAG" rom...but I'm not sure at all because it was installed several months ago or even years) with TWRP as recovery and Magisk as root.
I saw that Magisk not working (since when ? I don't know because it was not my phone). So, I tried to update it via the Magisk application (the initial goal was to use then Titanium Backup).
Logically, the phone then rebooted to install the Magisk update... except that a Boot Loop appeared.
I then tried many things :
1° Downgrade or Upgrade the TWRP recovery to 3.0.0.0; to 3.2.2.0 and to 3.5.2.9.0 (thes recovery .img files are here: https://eu.dl.twrp.me/herolte/)
=> It didn't work, and the bootloop continued (but, at the end, i keep the TWRP v.3.5.2.9.0)
2° I tried to uninstall and reinstall Magisk
(cf. the "Custom Recovery" tuto here : https://topjohnwu.github.io/Magisk/install.html#samsung-system-as-root)
=> Failure. Still the BootLoop... (either with the .zip v19.1 or the .zip v23)
nb: I even tried to donwload other magisk files but still the same bootloop (cf.https://forum.xda-developers.com/t/collection-of-magisk-modules-v2.3575758/page-13#post-72542167)
4° I tried to change the kernel by using TGPKernel (https://forum.xda-developers.com/t/...2-30-tgpkernel-v6-15-5-3-18-140-esd2.3462897/)
=> Failure, the bootloop remained...
5° Finally, I found a solution :
a° I downloaded the rom "G930FXXU2DRAG_DevBase_v4.6.zip" (via the following tutorial here : https://forum.xda-developers.com/t/...vbase-v7-4-encryption-support-jul-10.3592914/)
, more exactly at the following location : https://androidfilehost.com/?fid=818070582850489124
b° Then, as indicated in the tuto (https://forum.xda-developers.com/t/...vbase-v7-4-encryption-support-jul-10.3592914/), I renamed the .zip downloaded on my PC to "G930FXXU2DRAG_DevBase_v4.6_rescue.zip" (ps: so, i add "..._rescue.zip)
c° After that, I copied the file "G930FXXU2DRAG_DevBase_v4.6_rescue.zip" on my micro SD.
d° In the recovery I finally installed the file "G930FXXU2DRAG_DevBase_v4.6_rescue.zip" and the phone restarted after a long time (or maybe 5 minutes, I didn't watch).
=> End of the bootloop and all data was preserved!!!
I had Magisk v14.0 running on my phone, which was installed using the patched_boot.img method. I had the stock recovery, stock ROM and kernel. But... a Magisk module I wanted to install required me to update Magisk, which I did using the in-app updater. On rebooting, the phone hung with a pulsating Samsung logo. I left it overnight to ensure it wasn't just a very long boot up.
I have seen a number of threads with people with the same solution. A fix appears to be to flash the latest Magisk-uninstaller zip then move back to Magisk 14.0. In order to do this, I flashed TWRP after reading the official thread but didn't swipe right (step 9 of the official guide) to allow system modifications and I didn't install SuperSU. I figured this may interfere with Magisk's systemless root. I did immediately flash no-verity-opt-encrypt-6.0 after flashing TWRP but I was still stuck at the pulsating Samsung logo. Since flashing TWRP, I have tried uninstalling Magisk, flashing no-verity-opt-encrypt-6.0 and reinstalling v14.0, v15.3, or removing Magisk completely. Doing combinations of these in the various sequences as suggested by those who have solved the issue from reading this thread and similar ones.
Should I allow TWRP to modify the system by swiping right and try the steps above again?
Assuming it's my boot.img that's cuasing this, I have tried signing but boot image with Chainfire's .zip that's mentioned here but that zip stopped flashing with an unexpected error.
The last thing I tried was to flash the original unpatched boot.img via TWRP. This gave a boot loop initially but when I reflashed it and immediately flashed no-verity-opt-encrypt-6.0, it progressed a bit further but got stuck at the pulsating Samsung logo again.
This thread shows someone who fixed the issue by installing a custom kernel. I haven't tried that yet. Is this a good idea?
I would be very grateful if you can suggest a way to repair my phone.

Dont flash unpatched boot images using twrp
flash unpatched boot image or v14 boot image(that you made earlier) using pc ODIN/ any other prefered tool. Just flash the boot.img nothing else or you can use fastboot to only flash boot.img, it works 100% all times,after flashing it should boot normal
then make a new patched boot image for v15.3 from magisk app just as you made for v14 and flash using pc,then it should boot normally
many phones seem to show stuck at boot logo after moving from v14 to v15(especially v15.1 and v15.2) and also some some devices with f2fs storage seems working weirdly with audio mods.

I'm pretty sure that's one of the permutations I tried before but having just flashed those two zips again, after making sure any previous Magisk installations had been removed, I get the same result - stuck at the pulsating Samsung logo.
If someone can tell me what parts of the system the problematic in-app upgrade from v14.0 to v15.0 would have affected then I could perhaps have a better idea of what I need to fix to get my phone starting up again.

Have you tried flashing your stock boot image or even dirty flashing your entire system with ODIN (as suggested above)? Magisk only edits the boot image, nothing else.

Sorry, my mistake. I did flash boot.img via Odin. It was the original boot.img file that I fed into Magisk v14.0 so it could create patched_boot.img.tar that originally worked. I'm going to try that again now.

That's good to know, thanks. I do have the full system from sammobile from which I extracted boot.img, so could try that if the 'lighter touch' approaches fail.
UPDATE:
After using TWRP to uninstall Magisk v15.3, which restores the stock boot.img, the phone hangs with a pulsating Samsung logo.
Using Odin to flash boot.img.tar (which I extracted from stock ROM) in the AP slot, I get a different behaviour - a boot loop which shows the "Samsung Galaxy S7 | powered by android" screen momentarily before going black and repeating.
So, even with a stock boot.img (assuming I've got the correct .img, which I'm pretty sure I have) and that I flashed it correctly, again, I think I have) then there seems to be more going on than just a corrupted/incorrect boot.img.
What next? A dirty flash of the stock rom?

did you flash the previous v14 patched boot image again using ODIN? this should work
same boot loop problem prevailed on my s7 active and lenevo k8 and flashing the v14 patched boot image and then making new v15.3 boot image gave a perfectly working magisk, although my redmi 3 was showing same boot loop problem and i have to flash the stock rom ( used twrp to restore nandroid backup but boot loop was not solved )
It seems your lots of permutations and combinations have damaged post_fs config of the kernel so you have only option left is to dirty flash the ROM.

I don't seem to be able to find the patched_boot.img.tar that I used originally with Odin. I've checked a few different machines and on various SD cards but I only have the unpatched boot.img.

Then you need to flash the ROM , if you got another device then you can make a patched v15.3 image and flash it
I used another phone to created a patched_boot.img.tar for v15.3 and flashed that with Odin but that gave me a boot loop. Trying this again but flashing no-verity-opt-encrypt-6.0 afterwards allowed me to get to the pulsating Samsung logo. So giving up on this approach, I dirty flashed my stock ROM and this worked but I was left looking at a pulsating Samsung logo for a nerve-racking 5 mins or more.
Thank you everyone for your help. I have my phone booting up again!
Now I need to work out install the latest Magisk successfully. If I try using the patched_boot.img.tar method with v15.3 then I'm back to the pulsating Samsung logo. Again. Using TWRP to flash the v15.3 zip gives the pulsating Samsung logo. I did select 'Preserve AVB 2.0/dm-verity. I also tried again with a clean stock ROM install and flashed the v15.3 zip and no-verity-opt-encrypt-6.0, as suggested by someone who'd successfully installed v15.3. I'm at a bit of a loss.
One clue, TWRP couldn't see the internal SD card data (iow /data). I wasn't able to check this option in the 'Mount' menu in TWRP either. I think this points to /data being encrypted. TWRP could see it yesterday, so perhaps I've inadvertently encrypted this. I was careful to uncheck 'Preserve force encryption' in Magisk Manager. I guess now that I've unbricked my phone, I should start another thread for this magisk install issue but any help or pointers to relevant threads that I may have missed would be great.
Thanks again for all your help.
Hey here
Im on android 7.0 and the device is galaxy s7 edge G935F and no matter what i do..... Unrooting with the managaer options or flash the magisk uninstaller in twrp it always causes a boot loop. It starts normal when i flash magisk again... it would be easy to flash a new rom but i want to keep some changes ive made while rooted so thats the problem and i read a lot of flashing the boot loader (thats the BL part in the extracted rom package right?) from the rom thats currently installed. But that would wipe everything right? Or can i somehow flash that one like i flash magisk in twrp
I wonder if here is anything i can do to unroot successfully? Cache wipe wont end the loop
As always thanks for your time and answer
With best regards
Chris
Today I updated my magisk installation from v17.3 to v18.0 using the Magisk Manager app, I rebooted my phone and I'm stuck on the phone logo.
I can get into TWRP, from there I tried to reinstall v17.3 and also uninstall v18.00 but for both cases I get "unable to open boot image" followed by a red "Error 1" in TWRP.
I have a OnePlus Two, running stock MM rom from OnePlus. Never had a problem with Magisk, any tips on how to fix it?
It's not a bootloop, I think boot image is broken.
Thanks for your help
I managed to fix this by downloading the stock rom and flashing the boot.img file inside using TWRP, reflashed Magisk 18.0 without problems.
Background:
Went to update Magisk via TWRP, phone now bootloops (and gets really hot when charging).
Before I go ahead with flashing an older firmware, to try and get it running again, I was wondering if there was any way of retrieving data from the phone?
I can still boot into TWRP without issue, although I did notice if i go to Install and select source, Internal Storage shows as empty, while External is fine.
Failing data recovery, any suggestions for unbricking it without wiping anything? I've tried un/reinstalling Magisk via TWRP, wiping data/cache/dalvik, but no luck so far.
Thanks
I know where i ****ed up now. By flashing Magisk directly from TWRP.
Tried reflashing it via the guide on page one:
"Instructions for Root Access"
A) Workaround for flashing Magisk with TWRP – for Advanced Users:
Now getting past the warning screen, but not past the Huawei logo.
Going to try remove Magisk altogether, and see if it boots up. If so, will install Magisk again.
Flashed original ramdisk.img and it now shows the boot animation, but doesn't get past there....progress i guess.
