I can't seem to get root on my Sm-T337A.
I want acheive root and learn to develop and experiment with custom ROMS. I'm very new to this.
I was able to install Odin and install a boot.tar file but the Tablet kept boot cycling into recovery mode. I tried what I thought was sidebooting files using adb, but apparently I don't understand how that works yet. I restored the tablet by forcing it into install mode (held down power, vol down, and home) then used Odin to install the boot(LP).tar file which restored the tablet. This ROM is indeed the AT& T Rom, but it is not the same one that came with the Tablet when I got it new (it has a different look).
Please help.
Here is the information on my tablet.
Android 5.1.1
Baseband Version - T337AUCU2BOH4
Kernal Version [email protected] #1 Thu Aug 13 17:01:34 KST 2015

I was able to root mine with KingRoot but after rebooting it said I had to take mine to the nearest At&t store. Yea...that won't be happening. Through Odin I flashed the LP boot tar. Fixed it. But I really want to gain root. There is no way around this? There has to be a way to unlock bootloader. Thanks in advance.:fingers-crossed:

If you could explain how to get around a locked bootloader you would make a lot of people very happy. Can't be done yet. That is the whole issue

Look up t337a temp root in xda. A guy says he figured it out but Noone has tried it. I use mine for work every day so I can't chance it. If you're brave enough to try. If it works put in a reply there and let me know. It says it works on our bootloader

hello,
i have a Samsung tab e sm-t561 , it is a NTTF study tab. i wanted to remove their OS and reload to stock rom. but when i try to update it via odin, it gives me error saying that the MDM MODE, CANT DOWNLOAD
REGARDS
I'm not having problems on my.
I own an SM-T561 and I were flashing many times without problems.
I needed to flash stock rom many times because there was no root and tried almost all methods I found, until we found a Russian site doing the root, and their method worked.
Can you verify the kernel and rom version?
unlock your bootloader

Unlocking your bootloader with adb/SDK would enable you to flash anything you want. Do this and notify me after unlocking your boot loader
---------- Post added at 05:47 PM ---------- Previous post was at 05:42 PM ----------
I got this tab from ohio state university when I was doing my masters.. And I just unlocked the bootloader using Android SDK (Google how to do this). After that, i've flashed my tab with TWRP recovery. Then, I have used Odin to flash custom recovery on my device. Works fine as hell. Just like a normal tab.

I just rooted my sm-t561 3g device
Hey I just rooted my Samsung sm-t561 device wanting to upgrade to higher version than Kitkat 4.4.4 but couldn't get any solution.
Hi I need some help please, not really technical but loaded the Android N beta on my Nexus 9 wi-fi, as it was crashing almost hourly I opted to restore it to factory defaults, it is now stuck in a boot loop. Tried to install the current supported factory image using ADB OTA sideload but it fails at 47% saying something like "Error: image is "flounder"; device is "".. as if the device has no identity.
the fastboot can see the device but ADP struggles. the device shows LOCKED at all times. any suggestions greatly appreciated
part fixed

I have now got my device working by sideloading Android N image, not achieved my objective of unenrolling but at least I have a device that boots, will wait for a more stable version eventually
What image are you trying to sideload?
Make sure your not using the LTE version.
Try sideloading the Android N OTA again.
Have you previously enabled OEM unlock in developer options? If yes try "fastboot OEM unlock".

Hi corkyejp and thanks, i was aiming to go back to current supported not the beta N release, I officially unenrolled received the OTA image, installed, got stuck in bootloop, tried sideloading MOB30G which i beleive was the correct wifi not LTE version (I saw that version mentioned in my crashlogs too). the device was in developer mode, I think but am not sure, however the HBOOT screens always showed LOCKED. i tried the fastboot flashing unlock (and OEM unlock options) but neither unlocked me. anyway at least I have a device that boots now, will put up with crashes if they occur. thanks again
If you are not an H918, H830, or US996 (Unlocked, NOT US Cellular) user, kindly leave this thread, this will not do anything for your device, exchange it if you're so desperate. Thank you.
Note for US996: It's probably easier for you guys just to flash TWRP the normal way and pull your battery then do the factory reset dance to get in!
Team Win Recovery Project 3.0.2-1
Alright, so you guys have probably heard about me working on this project for a week now. Sorry it's been taking so long, there's been so many variables and hurdles to go through!
I don't own the device myself, so it was all done over TeamViewer thanks to @slayerh4x and @Darriousx who stayed around in the #twrp channel on freenode to assist with their devices.
This will allow you to install TWRP and flash SuperSU!
Step 1: Unlocking your bootloader
You will need to unlock your bootloader first. For this you'll probably need LG's drivers.
Windows: http://tool.lime.gdms.lge.com/dn/downloader.dev?fileKey=UW00120120425
Mac: http://tool.lime.gdms.lge.com/dn/downloader.dev?fileKey=UW00320110909
You will also need adb and fastboot. You can download them in a portable small form factor here:
http://forum.xda-developers.com/android/software/host-tools-t3402497
Start by turning on developer options in Settings -> About device -> Software info -> Build number. (tap 7 times until it's enabled)
Now navigate to Settings -> Developer options -> OEM unlock. (turn it on)
Don't ever turn OEM unlock or Developer options off when using a custom ROM or recovery. This could lose to loss of all your data.
For your computer to see ADB, you will need to put the phone in PTP mode (for transferring images). I don't know why this is, a misconfiguration in LG's kernel gadget drivers maybe?
Extract adb and fastboot to a folder on your PC.
Type adb start-server and make sure to check the notification on your phone to accept debugging authorization.
You can reboot into fastboot mode with adb reboot bootloader once authorized.
If it fails to authorize or show the notification on your phone, you may need to try other USB ports.
H918/H830 users only:
To unlock your bootloader, use fastboot oem unlock once the phone boots into fastboot mode.
Warning: This step will wipe all your data and factory reset your phone!
You can check the status of your bootloader lock with the fastboot getvar all command.
ex. (bootloader) unlocked:yes
You should now boot back into your phone (fastboot reboot).
You will probably need to complete the Android setup wizard at this point to get access to ADB again.
US996 users only:
To unlock your bootloader, follow the unlock instructions on LG's site (I can't really help you there):
https://developer.lge.com/resource/mobile/RetrieveBootloader.dev?categoryTypeCode=ANRS
Once you're finished with unlocking your bootloader, continue on to step 2.
Step 2: Running recowvery
You can find the recowvery binaries (you need to download all of these) at:
https://build.nethunter.com/android-tools/dirtycow/arm64/
You're now ready to follow the recowvery installation instructions.
See here: https://github.com/jcadduono/android_external_dirtycow#running (running section)
Bonus: There's also a full write up on that page on how recowvery works if you're into that kind of stuff.
Step 3: Flashing TWRP & Rooting
Notice: There is currently no decryption support, just the same as the LG G5, I'm running into the exact same scenario (unable to start rpmb device).
Due to this, I have disabled hardware decryption in this build to keep it stable. If you wish to have your data work in TWRP, you will need to disable decryption.
If you're coming from the Note 7 or S7, this will be a familiar scenario for you.
Once you've got your permissive shell in adb, you will have access to your partitions via dd.
You should transfer TWRP to your internal storage (name in twrp.img) using MTP, you can also just use adb push. (mentioned here)
Download TWRP: (official builds, V20 is waiting for TWRP 3.1.0 for twrp.me download)
H918: https://build.nethunter.com/test-builds/twrp/lge/twrp-3.0.2-1-h918.img
US996: https://build.nethunter.com/test-builds/twrp/lge/twrp-3.0.2-1-us996.img
H830: https://twrp.me/devices/lgg5h830.html
This step requires that you've used dirtycow to replace /system/bin/run-as with recowvery-run-as. If you've rebooted since doing that, you will need to go back and do that again.
Code:
adb push twrp-3.0.2-x-xxxx.img /sdcard/twrp.img
adb shell
$ run-as exec dd if=/sdcard/twrp.img of=/dev/block/bootdevice/by-name/recovery
"<wait for it to complete>"
$ reboot recovery
You should be inside TWRP now. It will ask you if you want to enable system modifications. You should swipe yes, otherwise your OS will replace TWRP on next boot.
Flash the latest zip from https://build.nethunter.com/android-tools/no-verity-opt-encrypt/ to turn off forced encryption at boot and allow you to boot a modified system. If you're flashing SuperSU.zip, it will also do this for you so this won't be necessary.
Warning: If you don't flash either no-verity-opt-encrypt or SuperSU, you will probably end up in a horrifying never-ending boot loop of "corruption"!
Latest SuperSU: https://download.chainfire.eu/supersu
To disable encryption after flashing SuperSU or the no-verity-opt-encrypt zip, you must use the [Format Data] button on the Wipe page in TWRP. No other options will work.
Back up all your internal storage and apps data that you can to your PC. You can use Titanium Backup with SuperSU before doing this step if you like.
Warning: Using [Format Data] will wipe all your apps and data (including internal storage) off the phone, giving you the out-of-the-box experience of a new phone!
Once this is done, you should be able to backup/restore/use any function of TWRP without any issues.
Flashed SuperSU? You're done! Boot up (it will reboot a few times) and set up your SuperSU Manager to your liking and give this post a thanks!
Step 4: Have fun!
I know a few people have mentioned donating, there is a button right on this post under my username.
Sorry, I don't keep a list as I prefer to keep people's information confidential, but if you do send any money my way, you can request that I mention you at the bottom of this post with any details.
I ask that people please not attach files in this thread, everything required is mentioned in this post, and should be stable in its present state. Thank you.
Thanks for testing on my phone! =]

Understand that I'm still working on getting TWRP to boot, there seems to be something about the stock kernel sources that doesn't want TWRP to be a part of it.
This will not get you SuperSU or app root access, this is only a root shell allowing you to flash TWRP when it's ready and do other things.
This does however open up some methods of installing SuperSU without TWRP. @Chainfire might have some ideas if he wishes to show up here and stir up some noise.
We do have the ability to do a full ramdisk unpack, edit, repack, and flash within the confines of /data/local while booted into the permissive system using recowvery-applypatch.
This should bring some opportunities, but it's still more sane to just wait for TWRP.

Thank you for taking the time to begin with the first step to develop on this device! (although i will have to do a replacement tomorrow for 2 defects that emerged on my phone) I always had in mind that this device had only a 50% of chances to get rooted, and that it might actually never get rooted . But now chances have increased even more thanks to your hard work. and also thanks to the others you previously mentioned. Let us see if Chainfire takes an interest on adding the final details :good:
I've got ADB working fine, but get nothing with fastboot. Just a blank line when I type 'fastboot devices'. Tried 3 different USB ports also. Windows 10 x64.
I did grab the ADB/fastboot files linked in the first post, but the older files I had don't work either, and they have no issues with my Nexus 7 2013 and HTC 10.

My advice? Never, ever take an update until the developers say that they are sure they can exploit it. From what I can see, this process uses the "dirty cow" exploit which will assuredly be fixed on the next security update.

Why not wait until they can get full root and TWRP? As I see it, this process is to help other developers and people that know what they're doing refine and advance the move to full root. I don't think it's quite ready for prime time yet. It does nothing but get the foot in the door for rooting.

For me, there's a certain amount of education that needs to be tackled before you start messing with a phone. I have never had a LG smartphone before, but rather quickly discovered that LGUP is not ODIN, and that yes, you can hard brick a LG doing stuff that a Samsung will shrug off.
Too many people are impatient and won't let the developers come out with a product that is relatively easy to use. Too many people won't take the time to learn what they're doing and how to fix their mistakes. Too many people won't bother to read and follow simple instructions, and too many people think their experience on other phones will play out here. The only thing this phone has in common with others is the basic Android. It's what LG has put on top that has given the developers a hard time. That, and Nougat seems to be a new beast to be slain.

yup! i couldn't have written it better hahaha. But it is bound to happen for some people that will not pay careful attention. I mena, im not an expert, im maybe a little more than a noob now since i have been dealing with this for quite some time, and that is why i just started my C++ class in order to reach at least a good-to-go level of understanding.
As this method does not ever mount your system r/w, it won't brick your system. Since it also can't provide you with real root access until you reboot recovery into a permissive system, you risk no chances of bricking your device if this is not for it, because if your device is locked, the recovery will refuse to boot and be replaced with stock again 2 seconds later.
Unfortunately I have not yet disabled verity in the fstab, so if a H918 user uses their new root shell to remount system as r/w then they will be bricked. I'll see if I can find a decent way to do this...probably with sed.
But yeah. You're safe if your bootloader is locked.

Locked or unlock

As this method does not ever mount your system r/w, it won't brick your system. Since it also can't provide you with real root access until you reboot recovery into a permissive system, you risk no chances of bricking your device if this is not for it, because if your device is locked, the recovery will refuse to boot and be replaced with stock again 2 seconds later.

Oh, ye of little faith. Where there's a will, there's a way.

Just installed SuperSU on a V20, based on @jcadduono 's initial work. Good times.
Can this method be used on other devices?

I got this phone from Tracfone, and I'm trying to flash TWRP recovery on this phone. I find the recovery image here: https://www.getdroidtips.com/twrp-recovery-galaxy-j3-luna-pro/
Thanks to the tool created by mkh.mourad(https://forum.xda-developers.com/showthread.php?t=2446269), I successfully converted the recovery.img to recovery.tar.md5. When I try to flash the recovery through odin, I got the error: SECURE CHECK FAIL: recovery.
I have enabled the OEM unlock and CROM Services.
Can anyone give me some help? Thanks.

I have the exact same problem. This is as close as I have gotten to installing custom recovery in order to root my phone
This recovery does not work on SM-S327VL. I have tried to email him and get him to take the garbage down but he seems happy letting people waste time trying to flash it.

I have the stock firmware if anyone needs it. It's the arf2 variety. Flashed it several times. Check hovatec if you want to find a root this year. I haven't found it yet but they are more active.

I think the problem could be that the bootloader is locked. I don't think there is a way to unlock it . I should be getting a new phone here soon, (Moto G6 that allows bootloader unlocking), so I will be able to test more freely with the SM-S327VL without worrying about bricking it.

From what I know enabling oem unlock is only half of the issue. I assume you forgot the adb steps to perform the oem unlock commands.
