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.

Im sure ill get flamed but i have searched and couldnt find an answer.
I have a z2 odexed stock with root. Just updated new firmware via pc companion to 17.1.2.a.0.314.
i downloaded the xposed installer and that went well. Then downloaded the serajrs xposed module so i can get different themes to work, extended power menu etc. everything seemed to install fine however now after rebooting i get this error.
it boots up but stays on the home screen and i can do is keep hitting ok to acknowledge the problem but i cant do anything else.
It was the stock rom so i dont have any custom recovery to go into to restore a nandroid or flash another rom (which i didnt want to do).
All i have is my titanium backup but i cant get past the error, any help would be greatly appreciated
* the error appeared about every 2 seconds so each time i hit ok, i was able to go 1 step each time. Basically was able to get into settings and do a factory reset which managed to do the trick. restored via TB so minimal setup time again. Would still like to know where i went wrong though but grateful didnt brick it lol (yes i can laugh about it now)
For next time: check the FAQ and stuck threads for info on how to temporarily disable Xposed (with or without a recovery).
The FC was likely caused by a module, so you should ask in the module's thread instead.
I wanted to try and hopefully learn little about rooting. Have been reading forumposts and tutorials for hours before I started.
Then I got this problem that I have been trying to solve for hours. But my conclusion is I need help solving it.
Tested on this phone that just were collecting dust.
Samsung Galaxy S5 Mini (SM-G800F) and I think it was running 4.4.2. (this is all I remember off the top of my head)
Problem / What happend (long version):
Rooted phone. Downloaded SuperSU and Flashify and installed TWRP 3.0.0 (http://forum.xda-developers.com/galaxy-s5-mini/orig-development/recovery-twrp-3-0-0-t3313775). I had no SD-card so I skipped doing a backup. Everything worked fine (for a normal user). Downladed a Root Uninstaller app also Debloater-setup-v3.90.exe (http://forum.xda-developers.com/devdb/project/dl/?id=12623). Did not freeze or uninstall anything before checking in this forum that it was OK. But after a while I could not access my homescreen it just turned up blank but I could still use other functions/apps. Rebooted the phone in order to get it to work but got stuck at the bootscreen. Tried to fix it via TWRP but the program freezes after a while or just reboots the phone back into Samsung bootscreen.
Problem / What happend (short version):
Rooted - got Flashify and SuperSU
TWRP 3.0.0 installed (no backup made)
Debloater-setup-v3.90.exe and some Root Uninstaller app used (searched on this forum before doing any changes)
Homescreen just blank, other functions/apps worked
Rebooted the phone and got stuck at Samsung bootscreen
TWRP access but the program freezes/reboot after short time
I did try "Factory reset". But the screen froze and the phone slowly started to heat up.
Later on I searched about it and it might have something to do with KNOX?
Any solution is fine since I don't have anything thats need to be saved. I can try any working stock/custom ROM (just not sure how to get it into the phone, yet).
Yes I am a novice so the simplest thing might even work.
Have you tried to flash stock ROM for your device using Odin? If it fails you may want to check this:
http://forum.xda-developers.com/galaxy-s5-mini/help/g800f-failed-odin-firmware-upgrade-fail-t3131782
If it doesn't fix your phone you may have a hardware problem.
I have the dual sim Exynos version, model number SM-N950F/DS.
I followed this guide 100% as said:

Root is not properly working. Unsure why. I rooted using Magisk. When checking the app, it has ticked both latest and installed version V16.4. When checking safety net option, both are ticked.
Adaway even after rebooting says ''rooted Android required'' . Root explorer not working also. The only thing I got working and only after rebooting it worked was Titanium backup. After rebooting I was prompted to give root access which obviously I did and it works fine.
However, other apps requiring root access do not prompt me to grant it root access and immediately says ''no root'' .
Any suggestions? Thanks.
Ps. I keep getting this annoying notificaiton on the taskbar saying ''Security notice. Unauthorised actions have been detected. Restart.'' . How do I get rid of this notification? I restarted twice yet it keeps popping up.
And now for no apparent reason I am stuck on the Samsung logo, phone is not booting up. The top left blue LED is flashing but the phone is not booting. Please help.
^ I managed to fix my device, like always I was running an older version of TWRP!! Happens every time with every phone regardless!
From one of the threads, I downloaded the very latest recovery and flashed it via ODIN. Voila! Installed one of the Note 8 roms and perfect. Everything working fine.
Why is it if using a slightly older recovery nothing works? I am unable to even format/wipe, install roms, nothing...
Hello all before I describe my issue lemme tell you how I got there.
First of all, new phone, couldn't install pixelexperience and flashing stock android was being a pain with all methods (read not working), only managed to install stock android with pitch black recovery.
After a while it auto updated to android 9 and I started having wifi issues that people told me were android's fault so I waited for an update. Update came but android was unable to install it, giving errors after errors every time it downloaded the update.
My solution to all of this was to flash another rom, either stock or custom, and pray it works. It was scheduled to happen in 2 days, when I had free time.
Today, when trying to change the permission for a text file for an app from read only to write, some random process crashed, and it triggered a crashing cascade, including the settings app, homescreen launcher, etc until the phone restarted and got stuck in TWRP logo screen.
No key press, combination, resets, etc would fix it. So I got into fastboot and tried a few things with no luck. Flash stock rom again and phone seemed to be working.
Magisk manager couldn't install magisk and root the phone so I went into stock recovery/twrp and every time I did it I got a black screen message saying something like this:
"Your phone/system is corrupt and won't boot ever again *evil laugh*. Oh btw, go to this link in another device to cry more"
and the link redirects to a google page with some non-useful info.
So here I am, unable to root, unable to go into recovery, phone boots though. I force-stoped updates for a while, as android 9 wifi issues were terrible, and I don't know how to proceed.
Do I flash a stock image again, a custom one, try another rooting method?
I don't want to brick a 6month old phone, really sucks.
Btw, is there a reliable way to back up everything in the phone ?(not only google stuff, but app configs and files/folders) Long time ago I read something about Titanium backup but never looked into it further and now with this crash that lost me everything I wanna prepare for the future.
Thanks for all the help and for reading my boring story.
Even I am facing same problem.. In my case my phone is rooted and I cnt flash TWRP and I cnt get into fastboot mode.. I alwys endup with black screen..
Hi all.
So this is quite strange (i think).
I managed to root my s20 fe 4g using magisk with the help of some people from here and a guide.
I have played around with it, installed some stuff, uninstalled some apps (using titanium backup) and was all well.
When I went to restart the phone to give it a clean break, it now wont load up again. Just gets stuck on the 'Phone is starting...' screen. Now this isn't a huge problem, i thought I couldjust flashthe stock firmware again and root the same way and perhaps it will be well. The problem is it wont boot into download or recoery because it is stuck in a cycle of trying to start itself. I can force it to restart by holding the vol- and power button, but that is the only combination that will make it restart, it instantly restarts before i can change the keys held to try and get it into download mode.
Does anyone know what I can do to try and remedy this so it will start again?
UPDATE:
I think i stupidly must have deleted the one ui launcher by mistake... Now I am trying to get an APK to the phone, but ADBdoesn't recognise it at the 'phone is starting' screen. My phon is at dead stage, so i can get it to boot into download now, but it doesnt seem to want to go into recovery, and i think its stock recovery, so not sure if ADB will work?
Any other suggestions to get the launcher apk pushed and installed?
if you can get download mode flash the rom again, hopefully you still have it from rooting.
don't use titanium backup to uninstall system apps. even using it to freeze apps can be a problem if it's not gonna boot up.
get a copy of a safe debloat list and stick only those listed packages that others have found to safe to deactivate.
