Hi guys,
I have successfuly updated my SM-G800F phone using G800FXXU1BOL4_G800FVFG1BOL1_G800FXXU1BOL3_HOME (Cyprus version) today. I also tried to root it using Odin3-v3.07.exe and CF-Auto-Root-kminilte-kminiltexx-smg800f.tar.md5. Unfortunately, this leads into instant boot loop. I just reflashed phone to Lollipop again. Can you help me with rooting this version?
Rooting certainly is possible, even on that exact ROM.
Some notes:
- With stock ROMs you should generally not root before you have completed the setup wizard
- The only variant of root that works with the stock Lollipop ROM is "Systemless" root
- The Odin version you're using is outdated. It *might* make a difference to update.
When you ran AutoRoot, did it claim it was performing systemless root?
Thanks for your reply, got rooted. I found CF-Auto-Root-kminilte-kminiltexx-smg800f was outdated too.
Any way to root 6.0.1 G920AUCS5DPJ1 yet? Did some research but could not find a way to root for this particular build. Any update?
I've been searching for an easier method to root my phone and I'm shocked at how few options there are to root my s6. I've always been able to come across more than enough information to root all the previous galaxy phones but for some reason there doesn't seem to be an easy method (like ping-pong root or something automated) I'd appreciate if anyone has any feedback on rooting the new build after the November security patch the build number is G925AUCS5DPK1

Feedback is, there is no root for the new builds.

And is there any way to go back to old builds flashing with ODIN an old stock firmware?
I confirm: once you get the phone on a newer version, you can't downgrade it. I tried to go from 6.0.1 to 5.1.1 flashing with ODIN. The ODIN process went well, but after the phone took the older load, it got stuck in the ANDROID screen
To get it back to life i had to flash again its original stock version at 6..0.1
So the question is if there will be any developement on S6 ATT 6.0.1 to get it rooted or TWRP. RIght now it seems we are stuck. No root, No custom rom I will keep my S4 that performs like a charm with root and custom roms!

Thanks @dandrumheller for the reply
I am debating myself to try something even i know is highly possible i break the phone. I really need a rooted phone and this s6 is a replacement for my s6 given to me by ATT. If i can't get it rooted, it will sit there forever. So probably i will take the risk to try to root/load anything experimental
:S
I'm trying to know if there is any way to root this device cuz I've been looking around and I haven't found a good tutorial on how to root this device in particular and I tried it earlier but it didn't seem to work at all. Any help would be much appreciated.
Is anyone going to help me with this? I have a Samsung SM-T377V tablet and I'm trying to find out how to root it. Thanks!
I had luck a few months ago using Kingroot v4.8.5 after downgrading the stock rom to android 5.1.1 (verizon's official build which the tablet originally shipped with at launch, Build LMY47X.T377VVRU1AOL7).
More recent versions of Kingroot simply fail and do not work. Also, the newer builds of the stock rom appear to be patched and I was unable to root via any method so the downgrade is required. (use Odin to flash verizon's original build)
While Kingroot does shoehorn a working way to root a running system, root doesn't appear to stick forever and eventually did stop working for me. I did have enough root time to at least break google apps and disable other bundled apps from running, but I wasn't unable to fully uninstall all the google spyware and verizon cruft - very frustrating!
Kingroot seems to take advantage of a zero-day vulnerability to grant us a rootkit.
I didn't have much luck replacing Kingroot with Chainfire's SU binaries to keep root working with something known-clean and backed by the community, which is a shame since Kingroot does appear to be running in the background doing who-knows-what with said rootkit. If you need root, Kingroot will get us at least that, but it's a two-way backdoor we're opening up and is really not a longterm solution.
Unfortunately, verizon has the bootloader locked down pretty hard. There's no way to flash in a custom Recovery which would open the door for developing a custom rom for SM-T377V with root already built in and none of the google/verizon undesirables. The current bootloader simply rejects any of the custom recoveries I've tried to flash in since they don't pass Verizon's signature checks.
What we really need is help from someone with experience cracking Verizon's bootloaders.. This bit is above my head and I'm at a roadblock.

So you're saying that the only way to root the device is to downgrade to an earlier version of Android, and because Verizon locks down the bootloader to the point where it rejects any recoveries to flash an older ROM, it's impossible to downgrade?
Not quite:
We can flash official Verizon roms without issue since these are signed by Verizon and the bootloader will accept them and allow the flash.
Downgrade to the oldest official Verizon rom using Odin, and root with Kingroot v4.8.5.
It's not a permanent solution since root doesn't stick for much longer than about a week, and Kingroot is of questionable safety in terms of privacy and your data. This is the furthest I could get to developing a custom rom for SM-T377V with root already built-in which "just works".
The Verizon bootloader is certainly aware that Kingroot has done something nasty to the stock rom - during bootup it now shows an Unlocked Lock symbol and says "CUSTOM" before loading the Verizon bootup animation (the animation is part of the rom). This behavior gets reset when an official Verizon rom is reflashed. I'm assuming a new official bootloader (signed by verizon) is being updated as part of their package as well.
We need the expertise of someone with experience cracking a Verizon bootloader so that we can flash a custom recovery which will allow flashing custom roms and making full backups.
I did attempt to flash TWRP in via Fastboot using root on a running system to circumvent the boot process and signature checking, but I was unsuccessful getting Fastboot working. I'm not sure that Verizon allows Fastboots for this reason.

So there's no way to disable Verizon's detection system that would make it reset the to the stock ROM after installing the previous version? I don't think I'd be with it to have my tablet rooted for only a week.
Root is working for the SM-T377V!
!! Great news! Your curiosity got me thinking about this again, and I got root working fully!
We finally have a working Root for the Samsung SM-T377V Galaxy Tab E 8.0" (Verizon)!
The trick is to use KingoRoot. (not Kingroot)
http://www.kingoapp.com/
First, downgrade the stock ROM to the very first version that Verizon shipped with. Build RU1AOL7, dated 2016.02.11. It's about 1.5gig, and I have no way to host such a large file, so search for it before you ask for mine. I found it pretty easily directly from Verzion. Use ODIN to flash it, yadda yadda yadda.
Then, use the Windows version of KingoRoot to actually root the tab. You will need to enable Developer Mode and USB Debugging, which KingoRoot walks you through if you don't know how. Be sure to uncheck the "Install recommended software" checkbox to avoid the bloatware they try to sneak by you.
After it finishes successfully, reboot the tab. During the boot, a message will pop up that says Android is Optimizing 1 new app. Badda boom, you're rooted!
To verify, use a Terminal Emulator and type the command "su" and press enter. If you're rooted, the prompt will change from a $ to a #. I also recommend that you use a root check app to double-check what is actually installed. I used "Root Check" by gsmdev since it's completely free and no frills unlike the other hundreds up on the market.

Please help!
Please post a link to the older version of the SM-T377V Build. I looked endlessly and could not find it.
I have odin and tried to downgrade to T337VVRS3BPL1 (5.1.1) from T377VVRS1BPL1 (6.0.1). It didn't work. Odin got stuck at "checking status".
Said screw it and tried to run kingoroot, on current build (6.0.1) and failed. :crying:
I can not find LMY47X.T377VVRU1AOL7 anywhere. I searched the verizon and samsung but could not find it.
try SAMMOBILE website for stock firmware

IDK about the 'LMY47X' prefix but the ROM/firmware T377VVRU1AOL7 (5.1.1) dated 02-10-16 is posted for SM-T377V on the SAMMOBILE site.
I found it, thanks!
I looked again and I was searching in the wrong areas. I couldn't find it on the Verizon website.
I downloaded it off of samsung-firmware.org
Temporary Root Successful
I was able to downgrade my MMB29K.T377VVRS1BPL1 (6.0.1) Marshmallow to LMY47X.T377VVRU1AOL7 (5.1.1) Lollipop with Odin with no problems.
Then I downloaded Kingoroot for Windows, and it took me three or four times to get it Rooted. The Root is only temporary though and I lose it after restarting the tablet.

I have made a post hoping that someone could help me. I've been having a really hard time trying to make this tablet stay rooted. I'm not sure if you've seen it. Here is the title of the thread "Rooting Samsung Galaxy Tablet E (8.0) SM-T377V Please Help".
https://forum.xda-developers.com/galaxy-tab/general/rooting-samsung-galaxy-tablet-e-8-0-sm-t3553154
Is that your rooted firmware or just the stock? I would really love if you could post your already rooted firmware that you are using because I keep getting stuck in bootloops with Kingoroot (I only get stuck in bootloops with the android version Kingoroot.apk, and Windows Kingoroot gives me a temporary Root and can't seem to figure out how to keep it rooted.
I wanted to ask you if it was possible for you to post your already rooted firmware of stock (5.1.1) since it is still Verizon I don't see how the Bootloader would lock me out. Would that work?
I'm trying to do the same thing you are trying to do and switch over to Sprint. :laugh:
I also cleaned up my posts on this thread so they're not all over the place.
Sadly things don't look too promising for this tablet, considering the bootloader's preventing us from installing custom recovery. Though, in theory, would it be possible to install a custom recovery by temporarily rooting, then using that to write a recovery.img directly to the recovery partition on the tablet? That'd get around the verification for installing custom recovery if that works...
Ugh. I'm seeing bootloops now too, even immediately after a reflash to stock and then running Kingoroot.
The stock recovery shows "dm-verity verification failed..." at the base of the window.
For those that installed Kingoroot, you can undo the boot loops by rebooting into stock recovery
Reboot, PWR + VOL UP + HOME, and select "wipe data/factory reset..." to pull out all the kingoroot binaries. (this step is necessary, unfortunately)
Then, PWR + VOL DOWN + HOME to go into boot loader mode, and use Odin to reflash the stock rom. This will at least get your tab back to factory stock.
I'm going to explore a bit more with Kingroot, I hadn't realized until I went to reflash over the bootlooping system that unless a full "wipe data/factory reset" is run prior to Odin, that most of the existing system remained intact. In my last writeup I did have a functional tab that could be rebooted without problems. I'm wondering now if it was a combination of the root tactics that I had tried earlier that were all still installed in the system that got things working....
When thing worked prior, I had been playing with: Kingroot 4.8.5, Official SuperSU, BusyBox-free, and of course Kingoroot

These were my thoughts too. If we can get root, we can flash over recovery.img using ADB and/or Fastboot. The latter appears to be disabled/locked, however. Also, I'm not certain that the sm-t377p recovery image will actually work... They're reportedly the same hardware, but one cannot be sure that things will jive with a crossflash at such a low level. My thoughts were if it's even an option, gamble it, and if the tab is bricked oh well...
This tab is worthless to me anyway if I can't pull out the Google spyware. Should have bought a rootable Tab A anyway, it would have been cheaper
I've gambled it quite a bit, over the process I've gotten stuck in like 7 bootloops, 5 soft bricks, and 3 hard bricks. Which is about 15 Odin flashes, or factory resets.
I had it temporarily rooted with your suggested firmware downgrade and Kingoroot windows version. The android version only gives me bootloops.
I've never been able to install SuperSu. It gets stuck at disable Knox. Which just ultimately fails and I don't get anywhere. I've used my temporary root and pirated Titanium Backup Pro to Freeze and Uninstall Knox. Which for some reason SuperSu still wants me to disable it and detects it, prevents it from installing.
I really wanted to try the rooting method with this tablet that was used on the SM-T377P because like you said about hardware. I'm not going to risk it, mainly because I need a break from running in circles with this damned SM-T377V.
So I recently flashed with Odin to get out of my last bootloop and my tablet came back on it still had the Kingoroot applications and Root Checker which I had downloaded before the bootloop. I was going to ask if these stayed on there because I didn't wipe to factory defaults before flashing?
Good luck and thanks again for all the help you've provided so far. We do have a temporary root with Kingoroot. I believe a lot of progress had been made. I'll update my thread and clean it up, just giving my experience with the rooting process of the SM-T377V. I'll clean it up when I can get around to it.
Thank you electronhacker.
Can I Re-Flash the current firmware (6.0.1) Marshmallow with Odin? I'm still newbie to Flashing firmware.
I'm an S7 Edge owner and one of these Tab E 8.0 SM-T337V and have some possible ideas for you guys to try. I've rooted my S7 Edge on Nougat Android 7.0. You can go into the Verizon S7 Edge forums to find a lot of this. Download the Odin Prince Comsy Edition. You are NOT able to flash a custom recovery to the tablet as Verizon and Samsung keep the bootloader locked down,even with root,there's no possibilities of a custom recovery. That means no custom recovery at all. Follow the steps on these websites and see what you get. There may be some possibilities here.

You should be able to to flash the stock firmware with Odin. I use Prince Comsy Odin as it skips SHA checks. Even with a newer bootloader version,you should be able to flash an older firmware. Just use the AP slot in Odin to do it and nothing else.

So you're saying that I can temporary flash a previous version of Android on the device but by the time Verizon checks the software the root will be voided almost immediately upon its exploit?

The problem I see with that is that those guides use an engineering bootloader specific for the S7. As far as I know, there isn't an engineering bootloader for the T377V. Sadly, still haven't found any reliable results in getting this thing rooted.
Is there literally nothing for this? I've got the method to downgrade to 4.1.1 but that only yields root apparently. No custom roms or anything.
Is there anything available for this tablet or remarkable about being on 4.1.1 I've searched both on all boards here on Tab S2 and it seems useless.
Aside from that, is there any way to unlock the simcard slot?
I apologize for the questions but it's looking like the tab may as well stay on 6.0.1.
Thanks for comments and advice, and yes, I've searched up and down (T817T all boards, etc.)
You have got to search and read through a bit more.
I only got this tablet (a used one of course) only 2 days back, so others may be able to help you more.
For me I just rooted the tablet and installed some xposed modules. For my need with the tablet, I don't need anything else.
Unlocking simcard slot has to be done from tmobile. I am not aware of any hacks available in xda.
You can install twrp and root the device if you want. T810/T815 they uses the same chipset. The information I have gathered so far indicate that you can install aosp roms for those models, but you shall not get cellular connectivity. Any chance of having official Nougat on this tablet is very very slim. There are some aosp 7.0 roms, but they are in early developmental stage; things like fingerprint sensor won't work.
Anyone feel free to correct me if I am wrong on any of the things I mentioned.
I no longer have tmobile.
Could I flash the t810 firmware onto the t817 tab s2? This way I could get the updates straight from Samsung.
I was only able to get one ROM to work on mine. Ultimately, I gave up and just kept it stock.

I'm also frustrated with the T817T. I have been able to root it, flash TWRP, but I have never been able to flash a custom ROM. I have heard that the T815 ROMs should work, but I get an error in TWRP if I try to flash one.
I was reading something in the Note 10.1 2014 forum that you could flash the P605 (International) ROM to the P607T (T-Mobile) if you unzipped the ROM, removed the modem files, and rezipped it. I'm wondering if something like this would work for the T817T as well.
If anyone has any ideas how to do this, please respond here.
