TETHERED CWM METHOD
​

** Disclaimer: This is not my work. I have just consolidated all information and files together into one simple STEP BY STEP GUIDE.

** Do at your own Risk. I am not responsible if you mess up your tablet. The method works perfectly on my 3840 and a fb friend 7840 without any issues and should work for everyone.

** This may work for some other Intel Chipset devices/tablets too. Inform me if it works for your model

WHAT IS TETHERED CWM?

Remember this is called "TETHERED CWM" method. Tethered means wired. Everytime when you want to use Recovery Mode, you need to use this tool by connecting tablet to pc, which copies recovery files "temporarily" in Tablet Memory and then you can use this temporary Custom CWM Recovery to do the Recovery tasks. When you reboot phone back to normal the CWM is removed from memory and you are back on that useless stock recovery. :D YES, its temporary and everytime you want to use Custom CWM, you need to use this tool. Quiet Annoying but hey, some things in life are bit difficult and you have to stay with it. :p :D

Preparations

==========

1) You must take full backup of your data in phone in sdcard or internal memory. No cry and complain later if you lose data. :p

2) Run Software Update (twice or more times) so you will be on latest Android 4.4.4 and there will be no update shown after that. I did exactly same.

3) Your PC must be installed with ADB and Fastboot Drivers already. You can Download Driver HERE or HERE or find it on Dell / Intel Driver Website.

* 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.

You must connect Phone to PC to test, so windows will finish installing drivers after detection of phone. (recommended)

4) Now 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"

5) Download THIS TETHERED CWM/TWRP FLASHING TOOL and copy and extract on any disk in your PC, but not on DESKTOP or C drive. I mean copy and extract anywhere on D or E or F drive onwards but not on C drive, to avoid permission issues of Windows 8.1

6) Download UPDATE-SuperSU-v2.46.zip (3.83 MB) and copy, as it is, on EXTERNAL SDCARD (recommended) or Internal Memory (not recommended). This exact file works for me and everyone. *Do not change it with other versions.

Now you are totally ready to ROOT.

LETS START.....

STEPS OF ROOTING

===================

Step1) Switch on Table/Phone Normally and connect to PC with USB cable. If it is first time, then PC will install ADB Drivers automatically.

Step2) 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 below.

Step3) 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

Step4) After ACCEPTing terms, on next menu, type "5" to select "CWM" as Recovery to load.

*Do not select TWRP right now as there could be some confusion later in this guide.

Step5) Now check that the tool running on command prompt box on PC is reporting as either :

DEVICE STATUS: ADB-ONLINE

DEVICE STATUS: FASTBOOT-ONLINE

*If device status is "Unknown" You may need to carefully start again from beginning.

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 and on PC too.

*Ignore error on last line in above image, its normal.

When done, phone will show you Fastboot menu. Now remove cable from tablet.

Step6) On Fastboot Menu, you need to press volume up or down to select "RECOVERY" option and press <Power> key to start phone in NEW CWM RECOVERY MODE. This time you will see completely different CWM "Vampirefo Venue8 Ver 6.0.3.7" with grey color background and with more working features of CWM.

Step7) 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) or 7840.

Good Luck guys :)
