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
Build Number LMY47X.T337AUCU2BOH4

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

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.
On the Motorola website it appears that there is no factory image available for my xt1622. This gets on my nerves, because I needed to switch back to stock & then the only option seems to be trying out various stock roms from untrusted sources.
On the Motorola site you can find some stock images.
https://motorola-global-portal.custhelp.com/app/standalone/bootloader/recovery-images
There you can also find the image for: XT1625, a model that is very similar to the XT1622. Only difference seems to be that it is 32GB internal sd card instead of 16GB. It seems to be only sold in the US where as XT1622 is a European model.
Since I was a bit desperate I tried the XT1625 on my XT1622 phone & it worked. At first boot there was an error about system ui, but other then that it seemed that everything works fine. If you reboot the phone there is even no error. In the settings my phone is also recognised as a XT1622.
Hope this helps someone somewhere.
Ok there is one caveat. I don't seem to get any ota updates. It took Lenovo very long to push out Nougat, but apparently it should be available now. It is not for me though. Might be some mismatch between this rom and the reteu servers it is contacting.
If anyone knows a fix for this then that would be cool.
You probably need to edit your build.prop file or something similar to reflect the correct model. In the end it may not work still if the OTA detects a hash mismatch with existing ROM. Your best bet might be to just ask Lenovo about the recovery image for your phone.

Try the image from this page:

Hello! thatsabadduck, my model is XT1622 DUAL sim. Can I use that XT1621-XT1622-XT1642_ATHENE_MPJ24.139-23.4_cid50_subsidy-DEFAULT_CFC.xml.zip ?

Any guides to relocking bootloader and restoring to stock on EU version of V30 ?

Should be as easy as using the "fastboot oem lock" command

Any reason you are doing this? The stock debloated, tweaked ROM in development section should give you all the features you need. You can also flash KZD without relocking bootloader.
LG still has a record that you unlocked your bootloader so it's not like they don't know.

Did you manage to relock the bootloader with the "fastboot oem lock" command (as it happens for other models)?
Thanks.
Yes, these are the commands i used to lock the bootloader again (note you have to setup the device again)
Code:
adb reboot bootloader
fastboot oem lock
fastboot reboot
what about the rom?
so when i do lock the bootloader, does the software get checked or updated or do I have to install it manually... what happens after i run all the commands in adb? Im currently on LineageOS 15.1 (LG-h930)
Question I ran fastboot oem lock and now I'm bricked with "your device has failed a routine safety check and will not boot" Does anyone have the fix for this?

You need to be on a stock KDZ(literally 0 changes) before locking. try booting to download mode by turning phone off and holding Vol+ and plugging into a computer. Then flash a stock KDZ.
thanks but slight problem is the device won't turn off.....

20e is the latest KDZ for US998(i assume thats what you have considering thats what is in your Signature). Use the LGUP_common_DLL_V30_ALL_VARIANTS attachment(there is directions in that thread on how to use that DLL).

Never seen that error. Maybe @ChazzMatt or @runningnak3d would know that one.
also at the bottom of the device screen instead of seeing device info I'm seeing 633A B100 on the top line and Modified / E /L / RO on the bottom
Happened to me as well. Do NOT use uppercut method, as it is not working on Oreo. Instead use lgup dev method. It is working.
As @kanehun stated, you must use the patched LG UP, and you must use partition DL mode (select all partitions) -- upgrade or refurbish won't work.
If you don't want to wipe your phone and just want to get it to boot again, only select recovery, boot and system and make sure that you are using the KDZ for the version that is on your phone. You should be able to salvage your data if you need to.

Does relocking the bootloader basically unroot the v30?
If not, is there a way of unrooting a US998?

If you JUST relock the bootloader you are going to cause LOTS of problems, UNLESS you first restore full stock firmware. Possibly even bricking your phone.
1) You want to flash stock KDZ via LGUP, which replaces TWRP custom recovery with stock Recovery.
Use "Refurbish" or "DL Partition". Then you no longer have root.
2) You can also relock the bootloader AFTER that -- if you wish to get rid of unlocked bootloader warning.
But step #1 will "unroot" your phone.

Completely different operations.
Unlocking the bootloader allows custom software to run because partition signature checking is skipped. This is what allows flashing and running non-LG ROMs, custom recovery, etc.
Manufacturers don't want you doing this because it enables updating the device once it hits planned obsolescence; they want you to give them another $800+ at that point, not keep updating what you have.
An example I like to point out: the Motorola Droid 4 stopped being supported at android 4.3 (Jellybean). Thanks to Safestrap - the bootloader is permanently fused shut but an exploit allowed loading an entirely different kernel and ROM via kexec after the stock kernel startup- and some particularly determined developers, it's running up to 7.1 (Nougat). The kernel is ancient at this point and spackled together with pieces from Amazon devices, and the phone is a bit slow using a modern O/S because it only had 1gb of memory, but it still works and people still use it as a daily driver because they like it. Last CDMA landscape QWERTY phone and all.
Root privileges are part of Android itself; think of it a combination of Administrator and TrustedInstaller account privileges from a Windows PC.
Google doesn't want you rooting because of the myriad ways the average user can ruin their Android installation by screwing with system files, the many security implications (easy example: let the wrong app have root, now the app has access to any data on the phone it wants and can manipulate whatever it likes), and it making it a lot easier to do things like block ads system-wide.
TL;DR bootloader unlocking is more device-side that disables certain "security" checks to allow booting non-OEM software. Rooting is software-side, lets you use the Admin account in Android for any number of useful shenanigans. They are independent of one another, but depending on the method rooting can prevent a locked-bootloader device from booting.
Hey guys.
I think I'll get the unlimited pass from Funky Huawei but how does that thing even work?
The page just says that it will grant access to their "tools" but what tools do they even mean???
I have rooted on Samsung and OnePlus before so I don't know why I would need those "tools" in the first place every time I want to access the recovery.
They have hisuite with routed DNS and a modified fastboot. :highfive:
Work to devices Huawei.
In my case, I trying to update the firmware, but problem in my PC, and No update..
A friend , change firmware, me no.
