Stuck in an odd bootloop, can't get out of it (SGH-T599N)

Hello all. I have been in the Android root community for a little over three years, and even after tinkering with the various devices I've owned since, I cannot get my T599N to come out of its current bootloop.
A background: I had been checking some things in my settings app (running stock, rooted), and I ended up just force closing the settings app to get out of it quickly. Well, this action deleted all of my text messages, and later on it removed my notification bar and made my wallpaper go black. I ended up booting into recovery mode to try and clear the cache. After it cleared, I rebooted, and bam, the bootloop started.
Now, here's what's interesting. The phone is in a bootloop where it displays the first boot message (SGHT599N Galaxy Exhibit or whatever), and then it tries to boot into cwm recovery, displays the loading screen for that for 2 seconds, and just reboots again. I've tried installing a stock rom from ODIN with no success. The rom apparently loads onto the device but it's still in the bootloop. After this, I tried to install philz recovery to try to install a zipped rom to get the device to somehow boot. I tried to factory reset it for installing purposes, and it just reboots. The device will literally clear everything but /data, so that makes me think that it may be a file system problem. I really need to get it to work, as I am out of a phone right now.
Does anyone have any suggestions? I've tried everything I know.

Infinite bootloop on Cyanogen modded S3 Mini... help!

I'm a complete newbie to android phone modding, and I was really proud of myself when I was able to install the Cyanogen 12.1 and Google Apps onto my Samsung S3 Mini. However, I made the mistake of trying to put my work email on it, which requires that my phone be encrypted. Well, I guess the encryption and rooted phone didn't want to play nice together, so I got the error message that my phone would be factory reset. Boo! Well, it got worse. Instead of a factory reset, my rooted phone now is stuck in what I have now learned is called a bootloop. Basically I turn my phone on, and the Cyanogen start screen (with the text "TEAMWIN") just infinitely flashes on the screen until I pull the battery.
I have tried using Odin 3.07 and cm12.1_golden.nova.20160210.ODIN_TWRP.tar.md5. I do the three button system boot, connect the usb, run Odin, get the phone recognized, and then install the .md5 in the PDA section of Odin. It tells me that it succeeded, but when I restart my phone it's still the same bootloop. I also tried swearing, but that didn't help either.
Has anyone else out there had experience with Cyanogen and this particular error? I would love to get this phone working again... preferably with either a Lollipop version of android or back to Cyanogen 12.1.
Any info would be greatly appreciated! Thanks everyone.

So I've got an update if anyone's interested... I can't call it progress, but it's a different problem now.
I was able to download and use Odin to do what was shown on this link: http://forum.xda-developers.com/showthread.php?t=2122548&highlight=root
Everything worked in Odin, the phone rebooted, and went to the Team Win Recovery Project diagnostics screen, rebooted again, and then to the samsung logo. However, it immediately goes to the "Encryption Failed" error screen, and the only option is to 'reset device'. Of course, doing this just reboots the phone and it then has the Team Win loading screen, Team Win Recovery Project diags screen, Samsung logo, and back to the 'Encryption Failed' screen again. So now I have a new infinite loop to solve. *sigh*
any thoughts?

Have you been able to get into TWRP? If you are, maybe you could wipe everything from there and flash the recovery version of your ROM.

I was able to put the stock bootloader onto the phone using Odin, download the original tar from here: http://live.samsung-updates.com/index.php?device=GT-I8190, then used the stock bootloader to install it from the sd card. Everything went fine, but now when I boot the phone it just hangs on the Samsung Galaxy S3 mini GT-i18190 start screen indefinitely. Is this progress, or have I created a new problem now?

You're playing around with heavy stuff. I won't recommend using an upgrade flash (CM over Odin) as an full flash. Please try flashing a stock image.
If you did something wrong to the partitioning, then it's likely to not allow you to do a successfull factory reset. Maybe you can try re-flashing a stock Odin image with PIT repartitioning.
Remember to try to backup the EFS folder, doing that kind of flash might wipe it.

Rooting Samsung Galaxy Tablet E (8.0) SM-T377V Please Help

So I've had success rooting the SM-T377V thanks to electronhacker post on the forums.
I thought I would give my experience because anyone else doing this will most likely run into the same problems I did. I still have a few problems I am running into. I hope someone can help me out.
electronhacker had said to downgrade to stock firmware LMY47X.T377VVRU1AOL7 (5.1.1) Lollipop, from firmware MMB29K.T377VVRS1BPL1 (6.0.1) Marshmallow using Odin.
I ran into problems finding LMY47X.T377VVRU1AOL7 but I eventually did find it on samsung-firmware.org Thank you moonsh0t!
It did actually work and passed with Odin, however it got stuck in a bootloop. I thought there was nothing that could be done but after looking into the bootloop matter more I figured out how to get out of it and start it up.
1.) Wait for the device to turn off while it's bootlooping.
2.) Then hold down the power button and the volume up buttons to enter recovery mode.
3.) Restore factory defaults. "I think this actually gave me an error but clearing the cache got it to work."
4.) Clear the cache.
5.) Reboot the device.
There you have it now you're out of your bootloop, the device will start up now.
Now that we have downgraded electronhacker had said to run a program called Kingoroot using the Windows application.
I ran Kingoroot and it got stuck at 44% and my screen went black and would not come on or turn off. I am pretty sure you call this a soft brick, but maybe it's called hard brick as there was nothing that could be done.
So this is what I did to Unbrick the tablet:
1.) Hold the power button and the volume down button for 15 to 30 seconds.
2.) The screen should come back on.
3.) Scroll through settings to reboot device normally.
I tried to use Kingoroot again. This time it got stuck at 51% and my screen on the tablet got stuck. Nothing was responding, not the power buttons, the volume buttons, home button, nor the screen. This is because Google Application had showed up on the tablet while I was in the middle of rooting. The Google Application said "Do you want to enable Google Security?".
Again;
1.) Hold the power button and the volume down button for 15 to 30 seconds.
2.) The screen should come back on.
3.) Scroll through settings to reboot device normally.
The device booted normally and I tried Kingoroot again. I wasn't going to give up. This time it worked, 100% Root Successful. I couldn't believe it the SM-T377V was rooted. I checked and verified with Root Checker.
Now this is where I need help!
#1.) The device only stays rooted until you restart it. Then you have to Re-Root it with Kingoroot every time you restart. I found out if you run SuperSu and go into setting you can stop this from happening. I'm not exactly sure what you do yet because I can NOT get into SuperSu. It tried to install the binaries but gets interrupted by Knox. It says disable Knox on SuperSu but this does NOT work. This tablet does NOT have a way to open Knox in order to disable it. So I need to figure out how to delete it that way I can run SuperSu and stop the never ending root process. So if someone could help me figure out how to do that I would very much appreciate it.
So far I've figured out that you can run an application called Titanium Backup to freeze the Knox files and then remove them followed by a Re-Boot to get rid of Knox. I looked further into my SuperSu problems and found out that you can manually download a SuperSu.apk file that should bypass Knox and actually disable it.
Here is my new problem, installed Titanium Backup from Google Play Store only to find out that I can't freeze the Knox settings unless I pay the $5.99 for Titanium Backup Pro. So I removed Titanium Backup and downloaded Titanium Backup Pro.apk which I found for free on the internet. I can NOT install it though, because I have a new error that says "APP not installed".
This happens with the SuperSu.apk that I found on the internet too. I've tried a lot of things but can't get them to install. Google Play Store gives me error (-504) I've tried clearing cache and data for Google Play Store and Google Play Services but no luck. I even tried downloading APK Installer but it doesn't even work. Please help I don't know what to do.

<UPDATE>
I'm at a loss, so I decided to do a factory reset from settings and that did not get the applications to install. So then I tried to clear the cache but again no suck luck. Then I decided to enter recovery mode and factory reset, but then got stuck on "Your tablet is getting ready for you". or something along the lines of that and wouldn't get past that on start up. (This is because I disabled setup with another application, and is my fault.) Not being able to get past that I realized I had no choice but to Re-Flash the System Update LMY47X.T377VVRU1AOL7 (5.1.1) Lollipop with Odin and that was successful, thank God. Now I have to Re-Root and before installing the wrong applications, which are Google Play Store SuperSu and Titanium Backup. Reason being that once you install these once and uninstall them you can't install them again without getting error (-504) in Google Play Store or even outside the Google Play Store such as manually downloaded .APK files or you will get the error "APP not installed".
Here is my idea, and I haven't done it yet. Re-Flash, Re-Root, Install for the FIRST time the right SuperSu.apk and Titanium Backup Pro.apk in order to disable Knox and stop the never ending Re-Root every time the tablet it restarted.

<UPDATE>
I have been running Kingoroot with my PC using USB. This gives me temporary Root access until Re-Boot. So I installed Kingoroot.apk and tried using to mobile application but this one works, but I get stuck in bootloop on restart of tablet. Then have to Re-Flash with Odin to get out of bootloop. I'm not having any luck.
#2.) Even with my temporary root I can not seem to install Xposed because of SDK 22 not supported. I was wondering if anyone knows a way to get it to work on SDK 22 so I can run IMEI Changer. Unless there is another way to change the IMEI without Xposed.
Thank you to electronhacker for your post I found on this forum which has made me a lot of progress, and thank you moonsh0t for your help redirecting me to find that firmware. :good:

I just got a SM-T377V this weekend and have been trying o root it as well. Wow seems like nobody has had any luck getting a reliable root on it. Please update me as you keep at it! Brent your attempts at this are amazing!! Keep at it!

I'm trying to get this thing rooted too, so please keep me updated if you find a
Way!! Thanks for your help!

Yep
Ok

Same issues here. I never have trouble rooting with the APK, but its super annoying having to reroot all the time. also the superuser app is absolute cancer so learning to replace that would be dope.

Alright, so your goal is to run an IMEI changer, but why?
Also my luck was to get it temped root and try and use chainfire's supersu to take over.
from there I tried unlocking the bootloader with samdunk. The issue though, is the CID was deleted from the tablet, so when I restarted, never ending bootloops.
I just Odin'd it back to the AOL firmware today, will look more into samdunk later.

If you use Odin to flash android 5.1.1 via package T377VVRU1AOL7, you can use the kingroot or kingoroot app (desktop or android) to temporarily root the device. From there, if you delete the kingroot or kingoroot app from the device you can use SuperSu to take the binary over. From there you can use any flashing apps you'd like.
The issue is at this point, the second the device turns off, when it comes back it will no longer have root. (note so far in my attempts I've found that Kingroot, will reboot rootless, whereas kingoroot will bootloop.)
Kingoroot will bootloop because it modifies the boot file in some way, which causes the bootlooping. The work around to this is just flashing over the previous android. However, if you flash with Odin, you lose root, but keep your files.
Going back to flashing, when you attempt to use Odin to flash other packages, they are denied, due to the locked bootloader, however, you can use Flashfire to flash these firmwares. I attempted to flash the T-377P firmware and bootloader. Obviously the locked bootloader stayed locked, the recovery partition got errored out, but the android system itself actually started. Just sans root.
It's worth noting I've also attempted using SamDunk, the S5 bootloader unlocking tool, and so far all I've noticed is it deletes the CID file and doesn't finish. So I'm of the impression that the temp root, isn't a full root either.

TWRP soft brick?

After months of deliberation I finally decided to root my Note 9. It was the first time I've ever tried rooting and it seems to have gone horribly wrong. To root the phone, I followed the guide in the video titled 'How to Root Galaxy Note 9! [EASIEST METHOD]' on youtube which has an instruction link in the description. As a new user here, the forum doesn't allow me to post links yet, so please just type the title on youtube and it'll come up as the first result.
What I did was:
- unlocking bootloader
- Flash AP file with TWRP version 3.4.0
- Wipe data
- Since I was worried about using a software from an unknown source, I then flashed the official magisk v20.4 instead of the 'N9-S9_root_for_oem_issue_devices_v3' file recommended in the video.
After doing so, the note 9 restarted and showed the error message "Verification Failed, Unable to restart your device. The Integrity verification has failed. You need to reset your device to factory default settings. This will erase all your data.". I allowed the phone to reset.
Following this, the phone restarted and showed exactly the same message of 'verification failed' and no amount of going through the rebooting process resolved the issue. I googled the issue and was advised to flash the phone with Odin by going into download mode. I then tried to go into download mode, but the phone will simply not go into it and tries to restart the normal way. I also tried to connect to my laptop to see if I can flash with odin but the phone was not recognised at all by the computer.
I then tried to reboot using the twrp key combo and this worked. I then decided to try flashing with the 'N9-S9_root_for_oem_issue_devices_v3' file in the tutorial. Yet, this led to the same issue as with the official magisk file.
Looking at some rooting tutorials, I see that some of them recommend flashing CSC, AP, BL and CP instead of just the AP in the tutorial I followed. I then thought that perhaps the issue is I need to install a ROM on the device. I therefore tried to load the lineage 17.1 ROM in the micro SD card and installed it (top left option on twrp 'install') as well as the magisk and disable_dm_verify_forceencrypt zip files.
In hindsight, this was a stupid move from me - I did so I was in full panic mode at that point and desperate for a solution.
After doing so, the phone rebooted and showed a booting animation of a single blue curved line stuck with a circle rolling from right to left on it.
I left it for a while, hoping that it meant the new ROM was booting. 30 min later it was still stuck on the animation!
I then tried to reboot the phone. Pressing power button did nothing. I then tried different combinations and eventually power + volume up + bixby allowed it to restart in TWRP mode.
As of now, the phone is still in TWRP mode. The phone is still not recognised by my laptop and will not enter download mode if I press volume down + bixby when restarting.
I am fully aware that I've screwed up the rooting process and feel awful about it. It was the first time I've ever tried rooting and I really hope it is only a 'soft brick' and that my phone can be saved. I would really appreciate if anyone here could advise what I can do to complete the root process correctly from here?
Many thanks,
Sam

Is there a "download" or "bootloader" option when you press the reboot button in TWRP? My Note9 is on stock, so I'm not 100% certain myself. However if there is, that should take you to Samsung's download screen. This way you can send yourself back to stock if you give up on rooting your device.
BTW, I do recommend following a note9 rooting guide on XDA (it's not too hard to find) over a youtube video, since YouTube videos can often be out of date or a little sketchy.

Trying to root S10+ with Magisk, followed all steps correctly multiple times, but no success. Please help.

Posting here because S10+ forum had no responses.
Have followed these instructions: https://topjohnwu.github.io/Magisk/install.html#samsung-system-as-root
I have the G975F model and have successfully rooted an earlier version of android.
After downloading latest (android S) firmware, patching and flashing with odin, it restarts to initial setup screen, then I restart in recovery mode to restart from there, and phone starts as usual, again to initial setup, screen. Then I install and open the magisk app it is supposed to give me a popup to continue further installation, but I get no such popup. The app says: Magisk Installed: N/A.
Please help, I would like to have root to restore my titanium backup backups, and can't use my phone till then :/

Update: I tried to disable auto restart in odin and manually exit Download mode and held the recovery key combo when it rebooted, but instead of showing me the normal recovery screen, I get a small message in the middle of the screen saying "wiping.." and it just reboots into android without magisk installed.
Kindly advise.
