I am fairly new to Android, but I have it a go trying to root my new x8.3 today. I had previously successfully rooted my LG G4, and I figured it would be similar. Everything went fine until I typed LEAVE and then it went to reboot. I have since been stuck in a boot loop.

I can access the recovery mode where it gives me a few options. I have tried all of them: Factory reset, safe mode, USB debug, wipe cache. Only power down works. All others continue the boot loop. I cannot get it into Download Mode with the hardware buttons.

Any thoughts?
[G Pad 8.3 General] matthewsage:
Well, I got a kdz flashed and it's going again. It took letting it sit for a few hours, then holding down power button until it stayed off while vibrating every 3 seconds. Then holding down volume up while releasing the power button, with usb connected. That got me into download mode. It took me four different times in Download Mode before the LG flash tool would stop crashing while reading phone information. Now it's working, for what it's worth to anyone else.
[G Pad 8.3 General] nakamoniel:
WOW, this method rooted my gpad X 8.3 in 2 minutes. I have a question though. I believe its not flashing 3GB for sure as after copying system file to root folder and then flashing it using "dd if=/data/media/0/rootedsystem.img bs=8192 seek=44992 count=458752 of=/dev/block/mmcblk0" took about 3-5 minutes. does it have to be THAT big? not complaining just wondering. Thanks for putting together this method.
[G Pad 8.3 General] winpooh:
There is instructions on the OP for backing up the system.img but there are several emojis in the last line to run in send_command.exe... can someone tell me what those characters are supposed to be? Thanks...
[G Pad 8.3 General] thevance1:
I just wanted to say thanks for this method. Saw it on another thread. Works like it should. Now we need some dev support for a recovery, etc. Kind of surprising that there isn't a custom recovery being talked about or any roms. Not one thread.

---------- Post added at 03:36 PM ---------- Previous post was at 03:28 PM ----------

What I did was just download the rooted system image and use the command prompt to push that. No need to backup system image. Just make sure rooted system image file name doesn't get changed and is on the root of your internal storage before running command. Must be in send command mode, know what port you're on and have the correct drivers installed yup your computer. Sorry if that's tmi, just making sure you know. Also one of the commands didn't work for me the first time. Can't remember which one but I just retyped it and out worked. Good luck

---------- Post added at 03:43 PM ---------- Previous post was at 03:36 PM ----------

Send_Command.exe \\.\COM copy and paste this into your command prompt and add your port # to the end of it. Hit enter. Should be a "#" sign in the command prompt. Now paste your root file push command from the op
[G Pad 8.3 General] winpooh:
Thanks... I was gonna pull the .img and inject root myself tho brings I have a linux machine. Btw I did see a thread where a guy was working on compiling TWRP for the vk815. I'll try to find it again and post the link if I can figure out how to do that. I'm kinda new to xda...

Yeah please do. That would be great. I've been on here for a while but never really posted. I'm no pro. I pretty much just research and follow directions from the devs. I've noticed that some of the instructions nowadays aren't as detailed as they used to be.

Quick question about rooting the VK815: if I root, will that unlock it from Verizon? I want to use the tablet on my Google Fi account but cannot find any instructions for unlocking. Thanks!
[G Pad 8.3 General] roirraW "edor" ehT:
It's probably not locked to Verizon anyway. The VK810.4G isn't. If the VK815 is like the VK810.4G, it only has 4G radios and I don't know if it has the Sprint and T-Mobile bands that Project FI uses.
[G Pad 8.3 General] opendave:
When I put in my Google Fi sim it complains that it is not a Verizon sim. I can use Wifi, but that is it. But I should confirm it supports the Sprint/Tmobile networks too. Thx
[G Pad 8.3 General] roirraW "edor" ehT:
It does the same thing on the VS985 G3. That doesn't mean that the device is locked, it just means that Verizon's stock ROM is made to complain. :) Was Project FI opened up to use on any device? I know they were opening it up to more devices but hadn't happened to hear that they opened it to all devices, even though I think it wouldn't work on FI anyway.

Good luck!
[G Pad 8.3 General] opendave:
So far Fi is limited to a couple Nexus models for phones, but is unrestricted on tablets & other LTE devices that use a sim. Of course, that assumes they are unlocked and have radios compatible with Sprint/Tmobile. Fi does not charge a monthly fee for additional devices, they just share in your phone's data usage. So that saves $10/mo compared to Verizon - which is one of the reasons I switched. My bill dropped by over $60/mo with Fi.
[G Pad 8.3 General] roirraW "edor" ehT:
I see, thanks.

How long to push the img back on with DD?

I have started the DD command to push the image back onto the device but it has been sitting there for at least an hour now. I am afraid to do anything for fear of bricking it in the middle of copying.

Any suggestions?
[G Pad 8.3 General] mpdas108:
So I left it for two hours, nothing... Then I forced a reboot and the file system is exactly the same as it was before, no root. At least the device is not bricked.

Tried again, but this time the dd command just returns immediately without doing any work. I also tried the LG one click root with no success, any suggestions?

Also I do not want to use KingRoot, as one of the installed processes with KingRoot actually makes my /dev/video0 device busy, which I actually need available for a program I am writing. It is as very fishy... for no reason should a root application occupy my video device..

Btw, the device I am using is:

Verizon LG G Pad x8.3

Model LG-VK815

Software version VK81511A

Build LRX22G

Kernel 3.10.49-g860e1a6

Configuration version J14.LGE.VK815.0

I have tried on Windows 7 Pro and Windows 10 Home.
[G Pad 8.3 General] mpdas108:
Sucessful root!

SUCCESS! Instead of placing the rooted img file in '/data/media/0', I was placing it in '/data/media/0/Download'

I actually put the rooted img file in /data/local/tmp and used that instead. Worked fine.

Perhaps you can be more specific in your instructions with an actual adb push command including the proper location of where to put the rooted image. If that would have been there it would have saved me a day of headache.

You say :

But I think an actual command will really help people. for example:

adb push rootedsystem.img /data/media/0
[G Pad 8.3 General] MonaLisaOverdrive:
Clarification Question:

In the original post, it says "skip this step (step 2) if your version is listed below. Does that mean that if I want to use the rooted image (also from the original post) I should skip the step where Linux is needed and, after getting the tablet into download mode, push the rooted image to the device?

EDIT: Polite bump to ask if anyone knows the answer to the above. Pretty sure this is the only available root method for my device (Both OneClick and Kingroot failed)
[G Pad 8.3 General] MonaLisaOverdrive:
Unfortunately the above doesn't work...at least on my device. When I attempt to push the rootedsystem.img to /data/media/0 I get a "permission denied" error.
[G Pad 8.3 General] mpdas108:
If your device has software version VK81511A, then you don't need to modify the filesystem you pulled off of the device as in step two, just download the rootedsystem.img that is linked to in the OP, and push that on to the device. If you have a different software version, then you should follow all steps.

I actually used '/data/local/tmp' instead. So here was my command:

adb push rootedsystem.img /data/local/tmp

Now when you enter 'Download mode' to run the final command, since you pushed the rootedsystem.img into a different location than the instructions you'll need to modify the 'dd' command to as follows:

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

Hope this helps!
[G Pad 8.3 General] MonaLisaOverdrive:
I did all of the above (read through the first few pages and found the answer to my orig question) before you replied but thanks very much!

Posting this from a rooted tablet using tapatalk…haven't figured out how to thank replies in this app yet
[G Pad 8.3 General] player911:
I never used the adb push command. I just plugged the phone in and used MPT to pull up files and drag and dropped the prerooted system image over.

There are permission issues when pushing, like you said. If you do a push, you have to use a folder, like you did, before it will work. Then just edit the flash command.

Anyway, either way works. Drag n drop is way easier.

Everyone can SKIP the linux part. Those instructions are just for reference.

Download prerooted image

Drag n drop onto internal storage

Boot into download mode

Flash rooted system image

[G Pad 8.3 General] SLAB_8002:
For what it's worth, I'd had my tablet for several months before I chose to root it, and I wanted to keep my app data and settings. Even with almost no knowledge of Linux, I found your instructions very easy to follow. I think the part that took me the longest was figuring out how to share a folder between Windows and the Ubuntu virtual machine. Once I figured that out, the rest was easy. Thanks for posting that.
[G Pad 8.3 General] Einsteindks:
Any way to use the rooted image from the external sd? And, the dd comand, is that entered from an opened comand prompt from within the folder of 'lg root'?
[G Pad 8.3 General] Einsteindks:
Is COM4 the port that the tablet connects with in Download mode? Mine was COM3.

---------- Post added at 01:42 AM ---------- Previous post was at 01:40 AM ----------

If I replaced the path for the external sd card, whatever it was, would the program be able to flash it from there?
[G Pad 8.3 General] a.stewart4242:
This worked well, but I'm having a potential issue (quite possibly user error). After I obtained root access, I used Automate to control my tablet as a carputer. I installed it in the dash, and decided to reboot it to test out one of the automate features. When the tablet finished booting up, root access was gone, and SU closes after saying that SU binary is missing. Anyone run into a similar issue that has a solution that wouldn't require me pulling it back out of the dash (no access to the data cable). Also tried running a terminal emulator to see if I could pull up SU permissions, but the program force closes directly after opening. Thank-you.
[G Pad 8.3 General] Kilgrin:
thank you so much!

can't thank you enough for this method! i still did my own system.img backup just in case, but the rootedsystem.img provided work for me no problem. I wish this post was easier to find/marked as official root for this device, as I spent hours trying a bunch of the root scripts with no luck.

wondering if anyone has been able to install twrp/cwm? if not, at least i can debloat and get my xposed modules.

again, thanks so much! very happy now :laugh:
[G Pad 8.3 General] Mykalmunlight:
How do you flash the rooted system image in download mode without Linux?
[G Pad 8.3 General] Einsteindks:
Follow the 'original thread is here' link in the OP. Once you have the pre-rooted image on the root of sd card storage, you'll put the tablet in download mode and use the send command to have the tablet flash the image. Read through it carefully, and get your bearings before you start. That all is from memory, if you want clarification I can research what I left on my laptop.
[G Pad 8.3 General] SLAB_8002:
OK, so I decided I would rather unroot and install the new Marshmallow OTA, since I have been really looking forward to adoptable storage. I've been trying to reflash the old "system.img" that I made when following the root process the first time around. Should be fairly easy; copy system.img to the root directory, reboot into download mode, run "Send_Command" and flash the old image, leave download mode, and all is good, right? It's not working for me. Wondering if I can run this by you guys and see what I'm missing.

On the latest attempt, I ran

adb push system.img /data/local/tmp

This gave me the result:

4600 KB/s (3758096384 bytes in 797.736s)

After that, I rebooted into download mode, ran "Send_Command", and ran the following:

#dd if=/data/local/tmp/system.img bs=8192 seek=44992 count=458752 of=/dev/block/mmcblk0

After about a minute, it took me back to the "#" and I entered "LEAVE". Tablet rebooted no problem, only it was apparent the old image did not take - everything looked exactly the same as it did this morning.

Can anyone tell me what I am missing? I am downloading the stock 11A OTA image as I type this, and I will try that next (although I'd rather not go all the way back to the stock image, I'd rather do that and get the update).
[G Pad 8.3 General] valetz:
[MENTION=7297194]SLAB_8002[/MENTION]

I just loaded the OTA update for 6.0 (22A) yesterday, adoptable storage is not enabled.

(I was waiting for this also)

At least it isn't default, not sure if it can be changed...

When I insert an SD card I don't get the option the way I did on my CM13 phone.
[G Pad 8.3 General] Einsteindks:
I, too, had problems with that system image not taking the OTA. It had a modified system label on it. I found the kdz for 11a, and used LG 2014 to flash it on. No more modified system, and the OTA took nicely. I used Helium to back up all downloaded apps, first.
[G Pad 8.3 General] roirraW "edor" ehT:
Verizon's VS985 G3 Marshmallow doesn't include adoptable storage either, so I'm not surprised.
[G Pad 8.3 General] player911:
LG on later updates had blocked the DD commands that allowed users to push modified systems.

I have not taken the latest update because I figured we would lose root capabilites.

Has anyone tried keeping on 11A, and pushing the rooted Marshmallow system image over to see if it will boot? I don't think it would but as long as the older download mode is in tact you should be able to restore back to the last good version without much problem.

Honestly the X8.3 runs fine on Lollipop that upgrading to Marshmallow doesn't seem worth losing root access.
[G Pad 8.3 General] Einsteindks:
Anyone else having difficulty with their SD card unexpectedly ejecting? I suspect it may have something to do with plugging in the charger
[G Pad 8.3 General] Skizzy034:
I'm getting the OTA notification for Marshmallow. If I wanted to update, can I just take the update or do I have to return to stock first? If so, what needs to be done to return to stock after using this method to root (which I did weeks ago. Still rooted).

Also, is there a way to disable the notification for the update if I decide to stay on Lollipop?
[G Pad 8.3 General] Einsteindks:
The OTA will fail if not on pure stock. Not sure about killing the update notification.
[G Pad 8.3 General] roirraW "edor" ehT:
Hi. I have the VK810, not VK815, but I can speak from general LG experience. You'd have to flash a KDZ or TOT that's made for the VK815 to return to stock before taking the OTA. Additionally, I believe I've seen the VK815 Marshmallow KDZ, so you could download that and flash it directly using LG Flash Tool 2014 in Windows.

You can use the built-in LG Backup on your current stock-based ROM to back up all your stuff, move everything you want to keep to your external MicroSD card, then you could flash the Marshmallow KDZ with the CSE option which will wipe all user apps and all data including internal storage. Flashing with the "Normal" option (which doesn't wipe apps or data) might work for you too since it would effectively be like taking the OTA. If doing so doesn't work, you should be able to Factory Reset in the stock recovery and be good to go, or re-flash the KDZ with the CSE option, just be prepared to lose all your stuff so I'd do the LG Backup first regardless.

Again, based on experience with the VK810 and VS985, you should be able to use Titanium Backup or another app to freeze both System Updates apps and then you shouldn't get the OTA notification any more.

If TWRP exists for the VK815, you might also be able to flash my "No OTA" debloat zip that's in my signature below and also disable OTAs. If you don't have TWRP, you can look at the details of what the No OTA zip debloats and delete those apps/files yourself and reboot. It might take wiping Cache and Dalvik/ART for it to be fully effective once you delete system apps/files.
[G Pad 8.3 General] Skizzy034:
Oh yea thanks I forgot about TB.
[G Pad 8.3 General] player911:
Try it. I believe it will fail. If you rooted, restore the stock system image and update.

Marshmellow is not rootable and there is no way back to lollipop. It is. One way street. My advice is to use TB to freeze the system updater and stay on rooted lollipop.
[G Pad 8.3 General] SLAB_8002:
I contacted LG and they confirmed that they disabled adoptable storage because it would prevent users from using the SD card in another device. Thanks Captain Obvious. Oh well, I was only looking for adoptable storage to fix a problem I was having with one of my apps reading data on the SD card, and I inadvertently fixed the issue myself last week, so it's a dead issue. I did lose root access, but I to be honest I can live without it until I'm due for my next upgrade with Verizon, at which point I'm buying a Samsung. The VK815 has such a small user base that I've been pretty disappointed in the support and accessories available.
[G Pad 8.3 General] yossijoe:
Is it 100% confirmed not downgradable to LP ?

Thanks
[G Pad 8.3 General] player911:
As far as I know there was never a TOT or KDZ released for the X 8.3 since it was only released specifically for Verizon in the US.

On other phones, they have restricted the ability to downgrade, BUT have allowed back and forth between Lollipop and Marshmallow.

If we found the KDZ or TOT, I am pretty confident we could flash back.

I recently got a new x8.3 after my son shattered my original.

I just want to say that you do not have to load up and inject root every time. I have done the hard work already.

Quick steps:

Copy Rooted_stock.img to root of internal drive

Connect in download mode (off then hold Vol+ and insert USB)

Run command to flash it

Reboot

Most of the directions here are just instructions on how I did it for others to follow. As long as you have an x8.3 then the rooted image is already created for you.

No. In MM, they updated the download mode and it disallows DD commands used to flash the rooted system image.
