Root [GUIDE] how to root US LG G Stylo on 5.1.1 and unbrick :) updated on 9/2/2015

[steve19150]

Did you choose the correct com port and if you did. Did you run the LS TMP (supposed to be lower case) command twice?

It Worked And My Problem Was Tht I Used The Wrong COM Port & Thanks

 

[Kyonkanno]

hey thanks for the guide.

In the OP, you state that there is a method for 5.0.2. Could you give me a link to that method? I dont want to update to 5.1

 

[Kyonkanno]

I'm trying this but I can't push the files to the tmp directory.

Push_File.exe \\.\COM5 lg_root.sh /sdcard/lg_root.sh
Author : blog.lvu.kr
File : lg_root.sh
Path : /sdcard/lg_root.sh

UNLK : FAIL
OPEN : FAIL
TOT FileSize : 9319

SendStart
WRTE : FAIL9319byte sent

This is what I get. I'm also having the issue where while in Download Mode, my device manager tells me that the MTP cannot start.

.....mtp isn't supposed to work while in download mode...what gave you the idea that it would?and are you sure your using the correct com port?

 

[Kyonkanno]

yes, the port is the right one. And it is kinda communicating because when I type LEAVE once in Send_command.exe the phone restarts.

When I get to the "ls tmp" part, I get nothing. When I type just "ls" I get a root of the memory that has a bunch of folders but there is no tmp to be found. That why I tried "sdcard" with the same result.

Okay so your typing LS TMP lower case right?

 

[Kyonkanno]

yes, all lower case

here is the full log from a oneclick root script. I also did it manually, step by step and it always hangs there.

I don't suppose anyone has a vm 5.1.1 stock recovery img file?

Attention if you try this and end up with a brick or your device transforms and tries to destroy you; it's not my fault you did this not me. So just read all of this thread not just the O.P to get out of a bind if you reply with "the thread is too long i wont read it please help" don't expect anything short of "there's a search bar use it"

Attention if you bricked via trying to root with the 5.0.2 method on 5.1.1 then just run what is below and you will have a fully working and rooted Stylo

Hello there I and Unjustified Dev have figured out how to root this puppy with the help of a video on YouTube so please read carefully and copy carefully please

Step 1 make sure you have a Windows PC
Step 2 download the LG Drivers from here: http://www.mylgphones.com/lg-android-usb-device-drivers
Step 3 reboot your device into download mode
Step 4 download this folder and unzip it to your desktop: https://www.androidfilehost.com/?fid=24052804347799389
Step 5 now run ports.bat from withing the extracted folder, to find your correct port (use the one with: LGVZANDNETDIAG1)
Step 6 in the LG_Root folder hold shift and right click and choose open command windows here
Step 7 run Push_File.exe \\.\COM11 busybox /tmp/busybox
^^^^^(place correct number after "COM" with no space)^^^^^^
it will then give you a message for example:

C:\Users\juan\Desktop\LG_Root>Push_File.exe \\.\COM11 busybox /tmp/busybox
Author : blog.lvu.kr
File : busybox
Path : /tmp/busybox

UNLK : FAIL
OPEN : OPEN
TOT FileSize : 1048328

SendStart
WRTE : WRTE1048328byte sent

CLSE: CLSE

Step 8 run Push_File.exe \\.\COM11 lg_root.sh /tmp/lg_root.sh (same deal as before)
Step 9 run Push_File.exe \\.\COM11 UPDATE-SuperSU-v2.46.zip /tmp/UPDATE-SuperSU-v2.46.zip
Step 10 run Send_Command.exe \\.\COM11
Step 11 type the following ls tmp which will result in:
#ls tmp
FAIL
#ls tmp
UPDATE-SuperSU-v2.46.zip
busybox
lg_root.sh
now Step 11 run sh /tmp/lg_root.sh dummy 1 /tmp/UPDATE-SuperSU-v2.46.zip /tmp/busybox

which should give you:

Hi all I've had the stylo for a minute already and didn't have a PC, now I do but its on windows 8 which I don't like, will this,method work or run on 8 or does it matter?

do you have usb debugging checked in developer options? what happens when you have the phone booted up normally and you plug it into the pc, does it recognize it?

im not sure what you mean about MTP check i dont remember seeing anything about that

yes the drivers i am using is from above link and I am using the united install.

my problem is every-time i plug the phone to my laptop, windows 7 wants to re-install the drivers.

if i plug the phone after i have booted the phone regularly i get the pc reconizes the phone and i am able to read the phones data.

if i plug the phone in DL mode, the re-install fails

Did you seriously have to quote two huge posts just to ask if this works on Windows 8?? As long as your PC recognizes your phone and you have the right drivers installed it will work.

 

[6th_Hokage]

i was doing this on 10 soooo...

 

[greasemonky]

Will this work on virgin Mobile lg g stylo ls770 and will the root work on win 10?

 

[Sparow79]

Will this work on virgin Mobile lg g stylo ls770 and will the root work on win 10?

Worked for me. Same setup as you, m8. Not custom recovery though sadly.

 

[greasemonky]

How do you get into download mode?

 

[greasemonky]

Nevermind, googled it. Thanks, felt naked without root.
Now just have to wait for recovery and custom roms.

 

[Sparow79]

I don't suppose you have a back up of the stock recovery you'd be willing to share? Messed mine up sadly, hadn't found one yet.

 

[greasemonky]

I didn't know how to backup. I have root now. Will a backup of this help you out? If yes then just tell me how to do the backup and Ill get you the backup.

 

[Sparow79]

Unless I'm mistaken, you should just be able to install Flashify. Once inside the app, you will see options to make a backup of your Kernel and Recovery. Now, I'm hoping, all that need be done, if you to make that backup, then upload it someplace. Of course once you have it uploaded, your be able to share at will. Those of you with more experience, if this is wrong, please correct me. Until then, I think that's all you'd have to do and if it works, and you are able and willing to share that, gah, you'd be my hero, m8.

Here you go, this is the stock
