Cannot boot into system after flashing twrp - Samsung Galaxy S8+ Questions & Answers

Before i begin, im new to this root thingy and my english is not that good
I recently wanted to root my s8+ (exynos), i followed the instruction carefully, flashed the newst twrp version via odin but after that i couldnt boot into system. However, i could boot into twrp recovery mode but my internal storage is only 0mb and i basically couldnt do anything. I rooted my phone once but back then i installed rom incorrectly so i had to factory reset my phone by installing stock firmware also through odin.
I want to give myself another try to root but what can i do if i see this situation again? Thank you

[Q] Stuck on bootanimation. HELP

Tried looking everywhere, but couldn't really find anything. Any help is appreciated!
Alright some background info
I rooted my phone and unlocked the bootloader successfully. I wanted to do more, so I flashed TWRP onto my phone using JRummy's ROM Installer. I followed all the steps and successfully booted into TWRP recovery. I created a Nandroid backup and when I tried rebooting my phone it gets stuck on the 4G LTE boot animation.
I then tried wiping the cache etc. and restoring the backup I had just created. To no avail, the phone kept getting stuck on the boot animation. I've tried restoring the backup multiple times with no success.
On my last attempt I checked another box on the TWRP restore page, I think it was the VG5 verification or something. Halfway through what I though was going to be a successful restore, my phone reset and got stuck in the boot animation again. Now when I boot into recovery it's the stock recovery, not the custom TWRP as before. Tried clearing everything/factory reset and it still stuck on boot animation.
As a college student I'd like to get this figured out as soon as possible (hopefully before midweek, Friday at latest). If I can figure this out with your help I'll be very grateful.
If I can't find any other way, I'm willing to flash stock back using ODIN and seeing how that turns out. Also my home button is a little sticky so I doubt the Verizon worker would be able to boot into recovery or download mode.
Any suggestions?
For those of you TL;DR
1) Rooted phone / unlocked bootloader
2) Flashed custom TWRP recovery onto phone
3) Created a Nandroid backup from recovery
4) Tried rebooting and gets stuck on 4G LTE boot animation screen
5)Wiped cache etc. and retried multiple times. Doesn't work
EDIT: I flashed stock through ODIN and everything seems to be in order. I'll be trying to root and recover everything through TWRP again and if it doesn't work oh well. My end goal is to have a custom ROM
Maybe this will help you
Okay for your problem, if you can go to Download Mode and your recovery back to its stock form, your last option will be flashing it through Odin. There are several method and guides How to Flash via Odin. I will link to you all the guide and try it so your phone will be back to normal. Choose only 1 method
1.) [HOW-TO] Unbrick your soft bricked Galaxy S III (+ bootloader brick)
2.) Verizon Offcial VRBMB1 Odin Files, VRBMF1 Odin Files, and VRBMF1 Update Files
Must read first the guide and download all the necessary.
If your phone gets revived, you can try this method and choose TWRP recovery and update the recovery.

Really wierd soft-brick on gt-p3113

hi folks,
My device was on cm11 and I wanted to try the slim6 rom and the new TWRP update for the recovery. I tried the TRWP unified version of Andi but after the flash succeded , everything from the tablet (Rom, data, system, etc..) was completly erased. Now the new recovery dosent read anything, even if I put a SD card with the files to flash. I tried to flash a another recovery with odin but the odin program freeze when I select the recovery . I can't find any working links for stock firmware and the one from sammobile crash most of the time before the end.
Any ideas of what happened on my device ?

Something went wrong here. You can run 'adb logcat' to see the crash details while starting.
If you have a backup on twrp then restore to get phone working. You may need to flash the public and hw-data zips afterwards though.
If you don't have a backup then you could try flashing the C636 off line firmware and then use firmware finder to go back to your original firmware
Sent from my MHA-L09 using XDA-Developers Legacy app
you may just flash the modified recovery ( See Guide subforum ) ) to bypass the update certification and authorization and reflash an original firmware. your stored files will be lost anyway in most cases.
I would bet superuser ( shield ) and SuperSU ( Aurom) messed your boot image. Both are incompatible to each other and, afaik both are incompatible to twrp 3.1.
Flash TWRP 3.0.2.2, reboot to recovery again to change version, flash the rom ( f.e. shield rom), boot once up, reboot to recovery and THEN you may flash twrp 3.1
Thanks all of you guys, I've solved the problem, it seems that's something related to the sd card, I've formated the sd and transfer the files trough another phone and then put the sd on the mate 9, I follow the steps as followed before and works successfully, now I'm on AurRom and 182 firmware.

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.

May i ask someone to help me flash TWRP and root galaxy j4+ correctly? SM-J415FN

Today i tried to root my samsung galaxy j4+ SM-J415FN i failed. I Flashed TWRP using odin successfully but this is where the problems started. I tried to mount and access partitions to flash rmm lock bypass so i would not get locked out and no verity opt encrypt but i could not access the file. I could not connect to pc using usb. I decided to search on the forum. I cleared cache, dalvik, tried to format and repair partitions but it didn't work. After try to boot to OS i seen "recovery is not seandroid enforcing" error. I decided to flash stock recovery. I was stuck in only boot loop but the error stopped happening. Then i decided to re-flash the entire firmware and now im left with working os but i flashed polish rom but the language is not polish... its fine but how can i flash TWRP correctly without screwing everything up and root? i got every zip i need i think and custom kernel (i read that to root i need to flash custom kernel i didn't flash any zips and it because i could not access files from pc or on partitions (i read in a post on the forum that on android pie i need custom kernel to do rooting)).
So how do i flash it correctly and root without screwing up everything again?
And by the way version of TWRP i used is twrp-3.6.0_9-1-j4primelte.img.tar
The RMM/LG lock did not trigger
Bootloader unlocked
Edit: i found out that i flashed t mobile firmware
Oh yes and screen locks were and are disabled
TWRP showed that data partition size is 0mb
I'm also searching for a stable way to root J415FXXU6.
Tried the old method, but can't use lockscreen on it.
Edit:
Tested this tutorial so far lockscreen and root are stable
