[GUIDE] How To Root Lollipop 5.0 Dell Venue 8 7000/7840 - Dell Venue

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://forum.xda-developers.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:
http://forum.xda-developers.com/showthread.php?t=2975096
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:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
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:
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:
https://play.google.com/store/apps/details?id=stericson.busybox&hl=en
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.

BTW just tested after rooting and Xposed and GravityBox both work just fine.... Thank you Dell for making this thing mostly AOSP

You may want to credit some folks in your original post, for example (at a minimum) link to the place where you got the androidfilehost link, and mention the developers who created the tool.

How do you install xposed?

Flash the zip for the x86 based device located here http://forum.xda-developers.com/showthread.php?t=3034811 in social-design-concepts recovery, reboot and install the apk in that forum as well.

I just got this tablet yesterday and updated to Lollipop (it arrived with Kitkat still loaded) and then headed over to the forum to find out it was a 5.1 update that had just came out!
Saw this thread, got really happy, and now I'm bummed to hear people are having a little trouble getting rooted on 5.1. Chyrio, I'm really new at this but I've rooted a Galaxy S4 and a Oneplus One by unlocking and flashing TWRP and installing custom roms from there. I don't know anything about the Intel architecture at all, how does this differ in terms of unlocking and rooting?

I'm kinda new to it as well, but as far as I can tell, there isn't to much of a difference with how the android file structure is built. The hardware is different (obviously) creating the need for different drivers and new software. I know there is some kind of emulator for ARM architecture based apps in the OS itself but Recoveries and bootloader exploits are going to require redesign from the standard ways. Which social-design-concepts is hard at work on. Hopefully he can cook up something for us soon. I'm holding off on the 5.1 update for now waiting for the devs to work their magic.

the launcher shows:
Device Status: FASTBOOT - ONLINE
Why is this differ than the screen shots? could this be the reason why it can not get past this stage?

Same here... Device state: Locked.
Have you solved your problem?
Anyone had the same issue?
UPDATE: Bootloader unlocked. Device State: Unlocked. But know when I try to insert T4 it copies the files and on the tablet is says "Okay." The cmw does not open. Please help!
