Code to backup SYSTEM image:
dd if=/dev/block/mmcblk0 bs=8192 skip=44992 count=458752 of=/data/media/0/system.img

This is a pretty simple and safe procedure, all we are doing is pulling a system image. When I do this on my ROOTED STOCK original firmware, I get a 3.5gb system.img saved to the root directory on my internal storage space.

I just picked up my Verizon VK815 last night. It is currently un-rooted on 5.0.2, kernel 3.10.49, Build LRX22G. It is currently prompting my to install an OTA update, of which I am happy to wait on. I would be happy to contribute any backups that I can make. Take into consideration that I have rooted an ROM'd plenty of phones, but I am just starting to learn this devise. It is my first LG.
[G Pad 8.3 General] roirraW "edor" ehT:
At least on the Verizon G3, and I believe it's been the same on the VK810, you can't get a system image without root.
[G Pad 8.3 General] player911:
You can grab the system image following the guide. Pretty simple. With the device OFF, hold VolumeUp and plug in the microUSB to thr PC. You dont touch the power button. Just Volume Up and Plug in. It puts the device in download mode.

Then let windows install the download mode driver.

Use the ports.bat from the zip you download. It should display Blablabla-DIAG COM6 or whatever. Just have to see what COM port the diag is connected too. You'll also see a modem too but ignore that.

Then use the send-command.exe or whatever using the command "sendcommand.exe \.\\COMX". Where X is the diag port. Mine was COM6. My modem was on COM7.

Then you'll be at a pound sign #. Here you run the command I posted. Just copy and paste. All it does is makes a backup on the internal storage. It takes a minute to copy 3.5gbs.

But after a minute (not that long) you'll get a pound sign back saying it was done. Then just type "LEAVE" in all caps. That'll exit the shell and reboot your device normally.

Then just grab the system.img off your device and upload it somewhere. I know its huge but they all are.

I also made a dedicated thread for this going forward so I can update it with a proper procedure.

Evolwun, once we grab the stock image, you can do whatever. Rooting the first stock image uses another procedure, but I would hold off.

Once I get the original stock system backup, I'll take the OTA. Backup that stock image. I'll inject root and reupload it.

Then we'll have a method of going back to stock without flashing a KDZ (since we dont have one yet). This will allow us to deroot to take future OTA updates.
[G Pad 8.3 General] evolwun:
My first stab at this was not productive. The command line never returned to a pound sign. I let it sit for a couple hours. I will try again later.
[G Pad 8.3 General] player911:
do a "ls" aka LS command first

Because you can connect to either the DIAG port or the MODEM port. The Modem port will pretty much take forever to return anything. If you connect to the right port, do a "ls" and it will quickly display the folder listing. It is basically like using Terminal on a Linux box at this point. You can change folders and look around.

If you are on the right DIAG port and able to view files and folders, then the whole thing to backup the SYSTEM partition should only take like 1-2 minutes. It will return a pound sign. Then just type "LEAVE" in all caps. Pretty simple.
[G Pad 8.3 General] archrival:
The 11A KDZ is available here

I was rooted and was able to upgrade to 11A using the LG Flash Tool. I'm about to pull the system image and try rooting it. Worked for me on the G4, hopefully it works for this as well.
[G Pad 8.3 General] player911:
Oh snap I was unaware of the KDZ for the VK815. Nice to know.

I would make sure you backup the stock system image (11A and the OTA). I am stuck on Rooted 11A because of the previous old root method injected it via a script directly on the device.

It would be a lot of uploading, but I would try to upload what you can. I don't have my X8.3 with me or else I would KDZ back to stock and pull the system images myself. I will probably do that this weekend. So stay tuned.
[G Pad 8.3 General] archrival:
You can use this to extract the system partition from the KDZ if you would like.

[G Pad 8.3 General] player911:
I haven't used the LG Flash Tool since the G2. I remember there being a special DLL file specific to our device (I had a Verizon model). Did you have to make any changes or did it just work without a hitch?

Unroot this method?

I used the original method to root my vk815. However, I've had problems with about 10 apps that won't update and a couple new ones that won't install due to the 504 error. Tried all the recommended solutions, but they don't work. So I decided to unroot and do a reset to factory. I'd also like to take the software update. I searched, and most places say to use supersu and click settings and then unroot. I tried this, and it just seems to hang at the window where it says it is deleting root. Waited like 2 hours. Any suggestions as to how can I unroot this device?
[G Pad 8.3 General] roirraW "edor" ehT:
If a KDZ is available, flash it with LG Flash Tool 2014 worth the CSE option which will wipe user data and internal storage, so move anything you want to keep.

Or if you hook it up to a PC, if it's like other LG devices, it should default to installer mode. You can look at the virtual drive it shows on the PC, install the official software from there, launch it and choose repair mode.

That'll download the latest KDZ and flash it, then delete the KDZ. The first option is better because you can control which KDZ you're going to flash, and you don't have to re-download the KDZ every time you have to flash it. I have no idea if the latest update can be rooted.

I have a VK810 by the way, so I can't answer specifics about the service itself but the above is general information for all modern LG devices.
[G Pad 8.3 General] Bridge66:
I'm not sure what a KDZ is, or how to flash. Can you give any specific instructions?
[G Pad 8.3 General] roirraW "edor" ehT:
Google the following:

XDA LG Flash Tool 2014

That's what you use to flash a KDZ. You have to find a KDZ file for the VK815 - since I don't have the device, I don't know if there's links to them on here or where. You could try devtester.ro/projects/lg-firmwares/download.php.
[G Pad 8.3 General] Bridge66:
I tried this, but when I went into download mode, it tried to install the latest update, and just sat there. How can I get it not to go straight for that update?

Edit:

OK, I found where this is normal. Sorry for the newbness.
[G Pad 8.3 General] Bridge66:
It worked! Thanks for all the help!
[G Pad 8.3 General] MonaLisaOverdrive:
I'm getting an odd result when I use this method. The script runs, displays the commands, but nothing inflates or extracts. When I reboot, I don't have root, but when I run through this method again, download mode shows "Modified".

Here's the output of running the root script

#sh /data/local/tmp/lg_root.sh dummy 1 /data/local/tmp/UPDATE-SuperSU-v2.46.zip /data/local/tmp/busybox
ui_print *****************
ui_print SuperSU installer

ui_print - Disabling OTA survival
ui_print - Removing old files
ui_print - Placing files
ui_print - Post-installation script
ui_print - Unmounting /system and /data
ui_print - Done !

And here's the output of checking to make sure the files were pushed to the device prior to rebooting in download mode. Note: I created the supersu directory as a test:

#ls /data/local/tmp
UPDATE-SuperSU-v2.46.zip
busybox
lg_root.sh
supersu

Any ideas?

NOTE: I also tried typing in the command to run the root script manually...that didn't work either.

UpdateOne:

If I don't hear back from anyone I'll try

a) running the tasks from an admin command prompt

b) inputting the script commands line by line

UpdateTwo

Running commands from admin prompt gave the same results (see output in original post)

Inputting script commands line by line worked up until this one:

cat /system/bin/toolbox > /system/toolbox

which output a ton of garbage characters on the screen.

I'm guessing the problem is that /system isn't being remounted as rw...but that's just a guess. Any thoughts would be appreciated.

I never got this to work. I used the inject root method referenced here:

and I used the uploaded rooted OTA image.
[G Pad 8.3 General] mikekoz:
Thank you! However, a few things are not clear. First of all, the instructions for using the send command and putting the tablet into download mode that you have linked to are for a LG G4. Do I do this the way I did when I first tried to root my VK815 using these instructions?

http://xdaforums.com/android/development/guide-root-method-lg-devices-t3049772

Step two says to run in a Linux environment unless "version is not listed below." What version? Do you mean the VK815's current software version? Mine is VK81511A. I do not own a Linux machine and have no experience with it, so that would put me out of this picture!

If we take away step 2, I pretty much get step one and three.

Anyhow, it is late and I am not about to do this now. I do not want to screw up my new tablet! :cool: I am going to get some sleep and look at this tomorrow. Again, thank you for any more help you can provide!

[G Pad 8.3 General] Fangzhiy:
I got the same thing!! It seems like the file did not get extracte.
[G Pad 8.3 General] mikekoz:
OK, so in a nutshell, I put the tablet in Download mode and in ADB, run the command "Send_Command.exe \\.\COM (#), run the commands as posted in step 1 to backup the VK815 system image. Skip step 2 and download the rooted OTA system image. Then do step 3 to push the rooted system image to the tablet. Since we are using a precreated rooted system image, I am assuming that backing up the one on my tablet is just in case something goes wrong. Does all of this sound correct? :confused:
[G Pad 8.3 General] player911:
The steps for injecting root are laid out in my root thread.

Since I have already injected root and uploaded the prerooted system image, all you have to do is download the new system image, copy it over, and flash it.

Backing up your system image is a mute point because I already uploaded a stock system image. It is just nice to have BOTH images available in case there is a problem. System images are not unique. Backing up your system file will not be a full backup with your files/apps.

The only reason ALL the steps are laid out is for reference.
[G Pad 8.3 General] mikekoz:
Thank you. I just did that, but my tablet is not doing anything. It is in download mode showing a progress of 0% which is not moving even after sending the command through adb. I verified that the tablet was on com7. There was no error on the laptop after sending the command, it is just at a prompt with #. On the tablet there is a dialog box showing "VUSER_ALTES B100" on the top in grey , and "Modified" in red on the bottom. I copied the rootedsystem.img file to where the rest of the files are on my Desktop. This is the command I used to push the img file on the tablet:

dd if=/data/media/0/rootedsystem.img bs=8192 seek=44992 count=458752 of=/dev/block/mmcblk0

What have I done wrong?

EDIT: I just read your thread, and it looks like I was supposed to copy the IMG file to the root of the tablets internal memory. You also mentioned that after this is done, you lose internal storage due to the original system.img file still being on the tablet. Where is this file located so I can delete this after I root?

EDIT 2: After copying the img file to the root of the tablet, I pushed it again to the system and this time it worked! I do not know if this is typical, but the only difference I saw on the computer was after I pasted in the command to push the file, it took a while to get back to the # prompt. The tablet itself again did not show anything, and the progress bar never moved. After about 15 minutes, I just typed in "LEAVE", the tablet restarted, and I had root.

[G Pad 8.3 General] roirraW "edor" ehT:
See the screenshot that's attached to the third post.
[G Pad 8.3 General] player911:
Some basic knowledge would be recommended to do this. There are other threads (linked in the main post) with step by step instructions on how to get started. This thread is a continuation of those other rooting threads with specifics for our tablet. I have quickly listed the steps but purposely did not go into pin point details as the information would be repeative.

But I want to say, again, that if you update to Marshmallow, you will lose your ability to root. LG has closed the ability to flash root across all of the LG family of devices. If you get the annoying system update notification, just postpone the update and force close the System Update app in Application setting.

I did this and have not gotten the notification again. I am still rooted on Lollipop
[G Pad 8.3 General] harrisvt1:
Doesnt work with my vk815......... maybe because it got upgraded to mm 6.0?
[G Pad 8.3 General] player911:

[G Pad 8.3 General] roirraW "edor" ehT:

[G Pad 8.3 General] CanyonR:
Is there a specific technical reason that MM hasn't been rooted for the vk815 when other LG MM devices have been? Or is it that it's just not a widely used device so the right people aren't working on it?

Thanks

CanyonR
[G Pad 8.3 General] roirraW "edor" ehT:
Most likely #2. If you created a bounty thread and users upped a bounty for Marshmallow root on the VK815, that would increase the chances. You should specify the bounty is for root and TWRP. It might actually take TWRP in order to be able to root it, as has been done for other LG devices including at least one other recent tablet.

Of course, I forgot about the locked bootloader. Unless someone can find an exploit like Bump was found on old bootloaders for other LG devices, then you can't root Marshmallow without an unlocked bootloader.
