S8 Bootloop after unsuccessfully disabling xposed - Samsung Galaxy S8 Questions and Answers

So I had root on my s8 on oreo 8.0.0.
I wanted to disable xposed but got errors and when I tried to enable it and restart my device I got in a bootloop.
It stucks at the glowing Samsung Logo and I tried almost everything.
I tried to do the whole root process with odin again but I end up in the boothole.
I still have TRWP installed..
Any suggestions?

With the Samsung logo display how long did you wait? As it can take some time to boot into system.
Which exposed are you using?

always remember to flash rescure.zip from magisk folder will undo the last modification

TWRP and stock Nougat hangs at Samsung logo, trying to root phone

Just installed Nougat stock ROM for my S7 Edge with ODIN, and trying to root.
I installed TWRP latest version 3.01 and immediately after installed supersu 2.79 SR3 from TWRP.
At first I could not boot the phone because it kept saying I used the wrong PIN code for boot. I reflashed stock rom and was able to boot again (same PIN) - disabled PIN on boot, and reflashed TWRP and supersu, but it keeps hanging at the Samsung Logo.
Flashing stock rom solves it, but I still want to root it..
What am I doing wrong?
currently there is no reliable root for nouget roms. It is being worked on.

Thanks for replying.
In this case - even if the goal is to root - it seems the problem is with TWRP.. Even if I do not root, but just install TWRP, the neverending bootlogo shows up..
Nougat OS has been changed that all the old rooting and twrp need to be updated.
It will be a while till developers can modify the os to allow changes.
Have posted the same question in the TWRP S7 thread that I did not see before posting this one - sorry

Odin Rooting keeps failing on same and updating stock OS version?! SM-G928F 5.1.1

I'm having a lot of trouble with this issue, since it starting with me logging out of snapchat, meaning my login would temporarily fail because my device was rooted and had xposed installed. I tried the normal fix to clear the settings for RootCloak and then add Snapchat back to it. But this solution had stopped working. I then misunderstood a fix for uninstalling Xposed to uninstalling root, which I ended up doing so my device had no root and xposed installed. After realizing my error and that I now can't reach TWRP recovery to try and fix it, I tried to flash it with root so that I could start it again with a fresh root. But when I first tried it, it passed, but it was stuck on the samsung s6 edge + loading screen. At that point I tried booting into recovery with Pwr+Volup+Home but it didn't work, just returned a black screen.
Now whenever I try to flash it with the stock rom to start over again, I've now tried it twice, once with a 6.0.1 stock os which failed and one with a 5.1.1 stock which also failed.
What do I do to fix this? Can someone help?
Thanks.

[HELP] "Verification failed" after rooting with magisk via twrp. SM-J730F

I've been trying whole day to root SM-J730F... I just recently rooted other samsung with magisk but rooting SM-J730F is turning into a nightmare...
Model is SM-J730F/DS (country UK) but after bricking I had to install SM-J730F (country Luxemburg). I tested several twrps they all performed pretty much the same, this one I have installed now.
Then I copied Magisk-v16.0.zip to my microSD (only way I managed to solve 0MB storage problem), installed magisk via twrp, I already had OS installed so I rebooted to system but after samsung logo loaded I got "Verification failed" . It just keeps looping when reset device is clicked and the only options is to unbrick it via odin and get to square one again...
I unbricked it at least 20 times now, I'm getting really sick of this... Got any workaround around "verification failed" or maybe some other way to root SM-J730F with magisk?

How to prevent bootloop on j3 2016 after rooting

Hey people
I have a Samsung sm-j320f 2016, OS android 5.1.1 and im trying to root it.
I flashed trwp recovery mode uaing odin and i tried several times rooting the phone with superSU or magisk. Cut to the chase, i rooted my phone...after hours it powered itself off and kept bootlooping
I flashed the firmware using oding and its working again now
I tried again rooting it with magisk...same happened but this time o restored it.
I found out it was because of stock rom and touchwiz ui that causes bootlooping
I really want to root my phone and i dont know how should i prevent bootloop
Can you help me?

first thing, go back to the stock of your device, activate OEM unlock, download the latest version of twrp and install by DOWNLOAD mode, rom stock only supports SuperSu, if you want to use magisk, just use a custom rom (I recommend Viper )

HELP! S8 won't boot up!

I've messed everything up and now I'm devastated!
My S8 stucks at the very first screen (where it says: SAMSUNG GALAXY S8 - powered by android). It doesn't boot further this very specific screen. I have tried to update Magisk and Magisk Manager but only Magisk Manager seems to get updated successfully while the app suddenly says that the latest version of Magisk Manager required Magisk V19.XX hence I've tried to install it via TWRP. According to log screen, I've managed to install magisk via TWRP but after booting up, I opened Magisk Manager where it now says that Magisk isn't installed. I therefore boot into TWRP and tried to fix it since some apps of mine that required root access wasn't working anymore. So, I thought I must have lost root access. I once again boot into recovery, I uninstalled magisk and install an older version of magisk and magisk manager and also the no_verity patch. After that my Galaxy S8 won't boot up. It just stucks at the very first screen. My S8 (international version) is still on Nougat stock samsung firmware and I can enter TWRP but the phone remains freeze and stubbornly refused to boot up.
I'm quite devastated and I hope you guys can help me fix this issue!
Thank you!
Hi, well sorry if I am stating the obvious but I would format and install one of the many custom roms available...

Are there any solutions other than flashing a custom rom? Meanwhile, I have managed to flash Android 9 via ODIN and have TWRP installed but it won't boot up and stucks at the very first booting screens.
Any help would be appreciated!
Thanks!

Have you tried just flashing stock rom only to see if it boots up. You may have to do a clean install.
Problem sounds like you haven't decrypted phone and flashed no verity zip file.
You won't need to flash a custom rom to fix this.
As for magisk have a look through this very helpful guide for installs and troubleshooting.

I've managed to solve this issue by myself. But still, thank you so much! It's the thought that counts ? And yes, I've figured out that I haven't decrypt my S8. But everything is absolutely fine now and I feel extremely relieved. It took me 1 day to fix this major issue and I've encountered lots of difficulties while trying to fix this like bootloops, system won't boot up and managed to stuck at the very first booting screen again and the phone boot past the first booting screen and stucks at the second booting screen, and also bootloader error and stuffs like where realization hit me that I can't restore my nandroid backup while still on Nougat because after restoring it won't boot up. I therefore managed to flash Android 9 and twrp. My S8 is now on Android Pie with custom recovery and rooted (via Magisk).
