Help! LG Gpad X8.3 VK815 from VZW. Root/bootloader

[McCracken]

ADMINS! if im in the wrong place please feel free to move.

ok so for the life of me i cannot get this thing to root or even boot into bootloader to unlock. i have flashed back to stock but im not sure what else to do. i see people have successfully rooted but maybe im to late?

on android version 5.0.2
i have this installed http://forum.xda-developers.com/show...8#post48915118
as well as the full SDK
i have tried kingo, stump, and lg one click root.

i have tried several tutorials.

somebody please tell me what im doing wrong

When you say you tried the LG one click root. Did you run it manually or using the graphic UI?
Kingo i know won't work and Stump root was for devices with earlier Android versions.
Kingroot... I don't think would work but i have used Kingroot only on my own device once.

Also what errors if any are you receiving?
I won't be able to reply back possibly till late tonight as i have to work from 3pm CST till whenever i'm done.

I used the graphic UI and it was having me boot into download mode which it would then continue through the root and put superuser on my device however root check says no root access and superuser says the binaries need to be updated

I would first disable any antivirus apps on the device if you have them. Then run the old script method.

I will try this tonight and post the results. Thank you for the advice. I'm on a completely stock device so would there be any preloaded anti V on the device?

Possibly vzw security app, or lookout.
Also i would allow unknown sources and or apps under security. It's usually little things that cause issues.

 

[McCracken]

tried several times. i do not see anything on my device that appears to be an anti virus

 

[James L]

What kind of PC do you have a laptop or desktop? Are you using 2.0 USB ports vs 3.0 high speed ports?

 

[McCracken]

Desktop. 2.0 and 3.0

 

[James L]

In my experiences, using a port in the back of the tower works best. I'll have to look at the script it might just be a small error in the script.

 

[McCracken]

I will use a 3.0 port in the back when I get home

same results as before

My apologies i haven't been online much due to my new job.

Try this method it's not a one click but i have used it a ton of times. Copy and paste the commands if need be.
If it doesn't work the first time try a couple more times. Also using a 3.0 port usually doesn't work...

Send_command.exe flashes on screen then closes not allowing me to finish the process

 

[James L]

Are you adding the correct com port after send_com.exe?

I look in device manager as the one shown in the tutorial is not the one it'll show all the time. And you have 5.0.2 right? And not 5.1.1

correct 5.0.2
it doesn't give a chance to enter anything. send_com.exe just flashes a quick window then disappears. it worked previously but not any more
