[Dell Venue] Chyrio:
So I was poking around all over and there really isn't a good guide on how to Root the Dell 7840 after the Lollipop update. So I figured i would make one so others don't have to piece together info like i did.

NOTE: Dell just released LL 5.1 to the 7840!!! You can root it using xBIGREDDx's method here http://xdaforums.com/showpost.php?p=62013578&postcount=43

You can use this guide for social-design-concept's method that xBIGREDDx mentions in his new method! PLEASE SHOOT HIM A THANKS!!!!

Before we start:

A. the info in this article is collected from several other users hard work I am just trying to make the process simple i would like to thank the developers/testors that have gotten us this far

Especially social-design-concepts and his work here:

Please shoot him a thanks! We owe him for the mad skill!

B. If your device gets bricked for some strange reason or overheats and burns your house down again, for some strange reason. I TAKE NO RESPONSIBILITY, DO THIS AT YOUR OWN RISK.

So to start, download this:

https://www.androidfilehost.com/?fid=23991606952604606

And this:

https://software.intel.com/en-us/android/articles/intel-usb-driver-for-android-devices

And this:

https://download.chainfire.eu/696/SuperSU/UPDATE-SuperSU-v2.46.zip

Install the Intel Android Drivers first, worked fine for me on Windows 10, should work fine on 8 and 7.

Plug your 7840 into your computer and do three things:

1. COPY the UPDATE-SuperSU-v2.46.zip to your devices EXTERNAL SD CARD not the internal memory!!!

2. Enable USB Debugging after enabling debug mode (tap the Build Number under About Tablet til it says your a developer)

3. Disable MTP mode by going into the Storage setting menu option clicking the options button at the top right and unchecking MTP

Extract the IntelAndroid-FBRL-05-16-2015-PTR archive to your desktop (or where ever you want to open it from)

Open the folder and run the Launcher.bat file

Everything should be installed correctly as long as the Intel Drivers installed properly.

It will bring you to this screen:

Just type T4 and hit enter

Your device should reboot to this screen:

This is where it gets tricky, if you go into the device manager on your computer you should see this:

[IMG="Android-Phone"]http://i281.photobucket.com/albums/kk231/chyrio/aaaaaaa_zpsnhuwckuj.png[/IMG]

You will need to right click it and click Update Driver Software

Then click this:

Then this:

Select the one in the list that says this:

Then select the one that says Intel Android Bootloader Interface:

It should install properly, close all the windows and if you go back to your command prompt (the thing you typed T4 into and hit enter) you will notice it is already copying stuff:

When its done you will see it setting up the temporary recovery, looks like this:

Your device will boot into Clockwork Mod Recovery using the Up and Down Volume buttons and the Power button to select, select "Install Zip"

Then "Choose Zip from External SdCard"

Select the SuperSu Zip you put on here earlier

When it gets done go back to the first menu and select "Reboot System Now"

it will ask if you want to "Fix Root"

select yes

When you get into Android you will need to install Busybox for root to work:

And you should be rooted!! Worked for me no hiccups. I'm definitely no programming wiz but I'll try to help if something isn't working.
