dell venue 7 (retail) unbrick?

tried to post in the venue area but got a pop up saying i had to post here. so, heres the situation.

i have a retail dell venue 7, i dont know the model as i cant boot in to it (thus the problem) i did "not" try to root the device, 1.5 years old, checked some messages, locked it, came back later, it wouldnt unlock, did a hard shut down, went to start it up and it just sits at the dell logo. so heres what ive tried so far.

1. if i power on i get a quick USB logo flash.
2. if i power on with usb cable hooked to pc the USB logo stays on the screen.
3. if i go in to droid boot and try recovery it reboots to the dell logo and just sits there.

im legally blind and am having a bit of trouble getting around here but ive tried the "IntelAndroid-FBRL-07-24-2015"
using the above, if i boot in to droid boot it shows up as "android phone" i have to install the adb driver each and every time (windows 8.1) i dont mind that. the above sees the tablet and even issues commands. the tablet reboots and i get a logo with a hat, but it goes no further. if i hold power up and connect to the pc it shows up as a "CloverviewPlus Device" under intel Soc.

this is what "IntelAndroid-FBRL-07-24-2015" shows when i try to do a "5 cwm" then a "T3"

at which point the tablet reboots, but just sits there with that hat thing.
i dont care if i loose data, id just like to get this tablet back in working order. unfortunitly i have no idea how to do that. im comfortable with the command line but may need a bit of hand holding (i.e. step by steps, ive looked at the wiki but i cant figure it out sadly)

Dell Venue 7 Boot Loop Xposed Framework

Hi Everybody,
I am seeking help from all the xda devs to help me in this problem. My dell venue 7 3740 is in a boot loop,:crying::crying::crying:
So here's what happened:
After rooting my dell venue 7 3740 the first thing I did was to install Xposed Installer which was supposed to help me install Xposed Framework. I did everything correctly and when I rebooted my device it was stuck in a bootloop showing the dell boot animation again and again. I tried everything to fix including fastboot and recovery launching. Unfortunately none of these worked.So please help me find a solution to these problem.
By the way I also have warranty.


P.S I am willing to give 20 Dollars to the person who will help me fix my tab.
SORRY FOR MY BAD ENGLISH.

Successfully Rooted Android 4.4.4 on Dell Venue 8 LTE (3840Merrifield) India Version

NOOB'S GUIDE TO ROOT Android 4.4.4 on Dell Venue 8 LTE (3840Merrifield) India Version
TETHERED CWM METHOD
================================================== ===================
Visit and read this thread carefully before proceeding.

WHAT IS TETHERED CWM?
Remember this is called TETHERED CWM method. Tethered means wired. Everytime you start phone in recovery mode by connecting tablet to pc and copying files in Tablet with this ADB+Fastboot mode tool and use Custom CWM Recovery to do the Recovery tasks.

Preparations
==========
1) You must take backup of your phone

2) Run Software Update (twice) so you are officially on Android 4.4.4 and there is no update shown after that. I did this same.

3) Your PC must be installed with ADB and Fastboot Drivers already. You can find it on Dell / Intel Support Website. Or I will provide links later on request.
* Drivers can be easily installed and tool can work on any Windows Version. I did this on Windows 8.1 64 Bit Version without any issues. PIECE OF CAKE. If you have any problem installing then check FAQ section below.

4) On Tablet Open >>> Settings >>> About Tablet >>> Press "Build Number" several times to enable "Developers Options" in Settings. Now go back and again Open >>> Settings >>> Developers Options >>> Enable "Debugging Mode"

3) Download THIS ROOT TOOL and copy any disk but not on DESKTOP or C drive. I mean copy and extrac anywhere on D or E or F drive or onwards but not on C drive, to avoid permission issues of Windows 8.1

4) Download UPDATE-SuperSU-v2.46.zip (3.83 MB) and copy on EXTERNAL SDCARD (recommended) or Internal Memory (not recommended). This copy worked for me.

Now you are totally ready to ROOT.

STEPS OF ROOTING.
================
Step 1) Switch on Phone Normally and connect to PC with USB cable. If it is first time, then PC will install ADB Drivers automatically.

Step 2) Open folder on your PC where you extracted files of ROOTing Tool. Select "launcher.bat" and RUN AS ADMINISTRATOR. It will open Command Prompt Box with a Tool Menu as shown in thread mentioned at top.

Step 3) The tool menu will ask you to ACCEPT the terms, where you need to type ACCEPT in capital letters and press enter key to proceed.

When you type "ACCEPT" and press enter key, check that the tool is reporting as either :
DEVICE STATUS: ADB-ONLINE
DEVICE STATUS: FASTBOOT-ONLINE




Step 4) Now tool will be showing you three TRIGGER options to root. You need to type "T3" and start third trigger.

Tablet will immediately boot into "FASTBOOT" mode (DroidBoot mode). If it is first time, then PC will install Fastboot drivers to recognize device and in FASTBOOT mode, tool will copy TETHERED CWM on tablet and will show lots of text flowing on tablet screen. When done it will show Fastboot menu.



Step 5) On Fastboot Menu, you need to press volume up or down to select "RECOVERY" option and press <Power> key to start phone in NEW RECOVERY MODE. This time you will see completely different CWM with grey color background and standard working features of CWM

Step 6) Now select "Install Zip from SDCard" and select and flash "UPDATE-SuperSU-v2.46.zip" file.

YOU HAVE ROOTED YOUR TABLET DELL VENUE 8 LTE 3840 MERRIFIELD (India Version)

Good Luck guys :)
