[GUIDE] LG G STYLO How to root the T-Mobile 6.0 update

This guide was made before Kingroot was able to root the official update. But thanks to @oskar and @TheDerekHarper on XDA and to @josephwv on Android forums it is now comfirmed that Kingroot will root the official update. But first you must still follow steps #1 through #6 so Kingroot can root your device.
Now before Kingroot was able to root the update I figured out how to root the official update and it is not all to complicated. The following guide will walk you through the root process. But I am not responsible for anything that happens to your devices by using this guide as you are responsible for your device.
What you need:
1. A computer running Linux or Windows with adb and fastboot installed. (I used Ubuntu)
2. If you are using Windows you need all the drivers for your device installed. Linux users will not have to worry about this.
3. A functioning USB cable for your device.
4. Battery charged at least 50% just for safety.
5. The TWRP revovery.img, this is the same TWRP recovery we already have for the LG G Stylo I have just renamed it to recovery.img to make it easier to type the name in while typing fastboot commands.
6. The SuperSU-v2.65-20151226141550.zip by Chainfire. (All credit to Chainfire for this awesome zip.)
How to root your device:
1. I suggest you first go to Settings/General/About Phone/Software info and tap on the "Build number" until it says"You are now a developer". Then back out of until you are in Settings/General and go to "Developer options" and turn "Enable OEM unlock" on. This is to allow TWRP recovery to be able to boot. Also turn on "USB debugging" while you are there.
2. Download the SuperSU-v2.65-20151226141550.zip to your device. You need to move the zip file from your Downloads folder to somewhere on your external SD card as it will not be deleted from there when you use the "fastboot oem unlock" command in step #6.
3. Download the recovery.img to your computer. If you do not have adb and fastboot setup globally for linux or in your path for windows you need to move the recovery.img to the directory your adb and fastboot is in and open a terminal or command line (depending on your OS) in that directory or cd to that directory. If you do have adb and fastboot globally or in your path you can just open a terminal or command line in the directory you have the recovery.img or cd to the directory you have the recovery.img.
4. Once you have the terminal or command line open run the command "adb devices" to make sure your devices is detected by adb. You may get a toast pop up on your device asking if you to "Allow usb debugging". Except this as this is the RSA key you need to allow your computer to communicate with your device via adb. You should see something like "LGH631dffacad9 device" in your terminal or command line. If you see "unauthorized" instead of "device" you have not excepted the RSA key.
5.Now type the following command in your terminal or command line. Type "adb reboot bootloader". This will reboot your device to fastboot mode. Once in fastboot mode use the "fastboot devices" to make sure your device is recognized by fastboot. You should see something like "dffacad9 fastboot". If you are in Linux and get a error message you may have to use "sudo fastboot devices" for fastboot to work. (If you are using Windows and are having trouble with fastboot recognizing your device you need to install the device drivers. If it still does not work install the drivers again with your device connected to your computer in fastboot mode.)
6. To fully unlock your bootloader you have to use the command "fastboot oem unlock". You have to do this or this root method will not work. But be warned that if you do use this command it will factory reset your device. Plus you will get a line of text saying the bootloader is unlocked on the splash screen when you boot your device.
6-1: If you are wanting to use Kingroot to root your device you can reboot your device now. Open the Kingroot app and let it root your device and then use Flashify, Rashr, or a similar app to flash the recovery. Then boot to recovery and flash the SuperSU.zip in recovery and it will remove Kingroot and have SuperSU installed on your device.
7. Now you can do this two ways if you do not want to keep the stock recovery you can use the command "fastboot flash recovery.img" to install the recovery and then use the command "fastboot reboot recovery" to boot to the TWRP recovery. (If this command gives you issue like it seems to be for many then just use the the following method and then use Flashify or Rashr app to install TWRP after you are done rooting.) If you want to keep the stock recovery you can use the command "fastboot boot recovery.img" to boot to the TWRP recovery.
8. Once you are booted to the TWRP recovery you should make a full backup first so you have a backup to restore to in case things go bad. After you make a backup then select install and then find the SuperSU-v2.65-20151226141550.zip and install it. Once it is installed reboot your device to system. If TWRP gives you a warning about the su binaries missing and asks if you want to install thee su binaries before you reboot select no or it will interfere with the rooting process of the SuperSU.zip. When your device reboots it will boot to the LG splash screen and then reboot again. But then it will boot to the OS but it will take a minute. Make sure you let your device reboot all the way to the lockscreen or home screen depending on if you have a lockscreen enabled or not. You should be fully rooted after this, enjoy.

Resserved in case needed later.

Thank you.

Someone mentioned using the Kingroot app and I gotta admit, I was skepticle at first but after testing. I can confirm it works.
Just go go KingRoot.net, download their apk, install and run the root program. Igll work out of the box after, sadly I couldn't get the above method to work either with super su.

do the fastboot boot recovery.img so it boots up twrp then flash the supersu zip then boot your phone you should be rooted then flash twrp using flashify

I was getting the same error, ( in step 7 don't flash the recovery )
just use "fastboot boot recovery.img" and it will boot to TWRP without installing it
you can then install SU, ( note ) when you exit or re boot from TWRP it will say SU in not installed do you want to install it, I did the first time and it seemed to hose up, so I did everything over and the second time selected no to re install.
once booted I used flashify to install the TWRP img, and I am able to boot to recovery using Quickboot apk
on a side note I have SU installed, I can use root explorer and other apps that ask for SU access, but Titanium backup
doesn't seem to uninstall apps anymore, they seem to re install after a reboot
Hope this helps yall's

I gotta be honest... I'm pretty skeptical to try it. I've read of everyone having either a softbrick boot loop or the root just not staying after reboot. Yours worked for H631 T-mobile 6.0 and stayed? If you confirm T-mobile variant and 6.0 I'll try it. There's a lot of headache with this method for me (not saying it doesn't work). I bricked my phone trying to get the binary files for SU by trying to reroot. But unbricked it with LG Flash Tools and a stock kdz. So I don't want to brick it again twenty minutes later lol

Made a tutorial on how to get the marshmallow update (i.e. rom i've used.)
And then afterwards i downloaded Minimal ADB & Fastboot, OEM Unlocked the device (for safety) and downloaded the Kingroot Apk.
Installed it, and just allowed the program to root. It was pretty simple, haven't had any issues (i've even disabled OEM Unlock from the phone & USB Debugging.)
Hell, even adoptable storage is enabled for my phone too (but that's another tutorial from somewhere else.)
I do plan to make a root video, just so someone could see it and grab their opinion.
To be clear: I'm using a metroPCS LG Stylo. Also, only time the phone had issues was when i factory reset it to get rid of root. (didn't work)
so i had to follow the steps from the above tutorial to reflash the stock rom.

well this did it, the root actually worked.

I got a permanent root from the procedure listed on page one of this thread. The only thing I did differently was, when booted into TWRP and you try to re boot the system you will get the question if you want TWRP to install root. If you do allow TWRP to install root, you wont get root. At this point select the option to just reboot the phone. The LG Logo will appear twice before it fully boots. When the device is fully up, you will have root.

My apologies as I made a typo in the guide. The correct command is "fastboot flash recovery recovery.img" to flash the recovery. I will fix this along with another rework about putting the SusperSU.zip only on your SD card.

I do not know if you can use it or not as I do not have that device. But you can try it bit if your device does not boot to fastboot mode when you issue the adb reboot bootloader command then your device's bootloader is not unlockable and this root method will not work for you. But from the posts in this thread point out that Kingroot now works on the 6.0 update so you can also try Kingroot to see if it willroot your device.

Again sorry as this is fully my fault for making the typo on the fastboot command to flash recovery. I am fixing it as soon as I am done with this post.

Is there anyway to do this without wiping your data from 'fastboot oem unlock'? My bootloader keeps saying locked in fastboot mode even though I checked Enable OEM Unlock in settings. It won't let me boot the recovery.img because it's locked.

Hmmm looks like maybe fully unlocking the bootloader enables all fastboot commands. You can try downloading and installing Kingroot and root with it as the posts here comfirm it will root the update now. Or just u lock the bootloaderb but your device will be reset if you do.

What if we just enable oem unlock in both the system and the bootloader then use adb to push the recovery, superuser, and busybox to the system. King Root caused too many system instabilities, it had injected itself as a system app and after unrooting and uninstalling after a reboot I was left with a soft brick due to a secure boot error 1003. A stock 5.1.1 kdz and the lg flash tool was able to bring my Stylo back to life.
It could all be done by running a simple batch file bundled with everything we need for our device. Linux would probably be the better option but it could work the same in windows.

Cant instal any rom or even frimware on zenfone 2 laser ze500kl

Hi, I have a rly big problem. I was tired of waiting until I can update to 6.0 officialy, so I went other way, I wiped up system, and caches.
When I tried it to instal by ADB sideload this happend:

Don't try to install any custom ROM. You'll brick your device. So far there're no custom ROMs for our device. Have a look here http://forum.xda-developers.com/zenfone-2-laser/help/ze500kl-revert-to-lollipop-bootloop-t3380589 , I think it could help you...
Good luck!

So now for those with same problem I know how to fix this problem.
Problem was that I had TWRP which was working like charm, but, asus original firmwares are ONLY flashable with STOCK recovery.
And problem was that I have no card reader in PC so I done it this way... Flashed TWRP, connected OTG USB with stock firmware and firmware update to 6.0, using TWRP file manager moved those things to SD card and then turned back to stock recovery, instaled 5.0 then update to 6.0 (It took like 25 mins in total), then just rebooted and whoala, I got Zenfone 2 ze500kl with android 6.0 ezy but it took me like 24h with bricked device and destroyed nerves...

Screwed up phone while rolling back Android 7 - help?

So for some background, I was on EMUI 4.1 and successfully flashed to EMUI 5.
Then, I wanted to rollback so I flashed recovery again and stock firmware. I tried flashing with fastboot and didn't work. I tried using Huawei recovery 3-button method, no luck either.

When I was booting into Revolution recovery, I could not mount SD card and some other partitions so maybe that has something to do with the 3-button method problem... Furthermore, I don't know how to check which version exactly my phone is, all I know is that it was VNS-L31.
Now I'm stuck with a phone that is constantly rebooting so how do I proceed?

First of all...
Please tell me you have a backup of your Nougat ROM. If yes, restore it.
I have failed to go back to MM several times like you before.
It really is a question of using the right files.
First, flash the OEMInfo that is provided here in the forums.
Second, flash the right firmware. This one is tricky. For me, ONLY VNS-L31 Version C150 worked. No other.
Flashing with fastboot always never works. It always gives an error on system. So you need to find a firmware that works with 3-button method.
Your task now is the get back to working Nougat, since you did something wrong.
Unlock BL, flash Nougat recovery with fastboot.
Then,
easiest is like I said restoring a backup.
If you don't have one, try flashing the Revolution ROM by BadWolf.

Have just solved the problem with the steps from here.
From my understanding, it seems that I lost almost everything, device info, OEM info, recovery... So no technique was working.
The solution in brief was:
1. Go into bootloader to flash recovery (I used Revolution Recovery)
2. In recovery, flash OEM info.
3. Then used the 3-button method to install stock version for the appropriate model (which I could see from OEM info).
4. Unlocked bootloader, triggering a factory reset. (I was stuck in infinite boot before this point.)
As you say Schlengge, it is a matter of using the right files! Thanks. Problem solved.

Which original one though? I've been trying and downloaded any Full firmware I could find using a firmware finder, for my VNS-L31 but using the force update method in download so far all of them return an error: Incompatible with current version. I have also tried the fastboot update and separately flashing each file in the update.app . None work so far. I keep trying.

If you're on Nougat, try flashing it's files through fastboot. It worked for me, MM system.img gave me an error, but nougat flashed fine.

I believe ur in nougat beta... Just flash oem info and flash again the nougat from there you can start again and downgrade peacefully

your bootloader is locked

Thank you! I followed the instructions here with a slight variation. Because trying to install the update.zip file always gave me errors I extracted the update.APP with the update extractor tool and flashed cache,system,boot with fastboot. Then I opened the custom recovery, installed the other zip file and continued as instructed.

how did you check if it was unlocked? if it says so in fastboot mode it can be incorrect, even when you relock the bootloader it still says unlocked

I own a VNS-L31
Bootloader is unlocked
I tried to update to Android 7, but I bricked it because of the recovery was a TWRP for Android 6
Now, the device is bricked to the loading screen.
So, I tried with fastboot to flash files.
fastboot flash boot BOOT.img -> OK
fastboot flash recovery RECOVERY.img -> OK
but :
fastboot flash system SYSTEM.img -> I get the same error :
target reported max download siez of 471859200 bytes
sending sparse 'system' <451240 KB>
OKAY ( 20.390s)
writing 'system'...
FAILED (remote: sparse flash write failure)
finished. Total time: 20.720s

I tried with the toolkit to flash the 4 images, but I always get the same answer : no device detected! blabla
However, the drivers are installed. I installed HISuite before all these...
What I can do now with myt brick :
boot to fastboot mode
boot to eRecovery (but no way to download anything, I doesn't work...)
nothing else.
I read this forum and all posts relative to P9 Lite brick, but I can't do anything until the SYSTEM.img file is written to the phone
Thank you for reading me

1. Download adb drivers...search on Google adb all in one installer it's on xda forums.
2. Download adb minimal package also search on Google and it's also on xda.
Try those 2first .

Hi
ADB drivers are already installed, by the method you given.
I can use ADB, the P9 is recognized.
The problem occurs always and only with the toolkit. My device is not recognized with it...
I can flash recovery, I was able to use dload, I pushed a Nougat firmware, and now, I have a TWRP recovery, but the phone is always blocked.
With the recovery, I noticed another problem. As you can see on the picture, partitions cannot be mounted. I don't know why...

This device is really hard to flash some firmwares....
if you're out of options you can try to use DC Phoenix it cost 10-15$ i believe : https://www.dc-unlocker.com/DC-Phoenix-flash-repair-tutorial

I would try to re-flash Nougat by the dload method first. You could also try to flash VNS-L31C432B160. For some reason it is more readily accepted by a bricked VNS-L31 than other full firmware.
If that fails, I'd resort to DC Phoenix.
