Simple Root for HP Slate 7 (+ADB install)

Ok for all Slate 7 users, I found a real easy and secure way to root our device, no brick chance because it doesn't modify anything inside the tablet, you just push SU.

Way easier than having to install software you don't even know what it does...

The hardest part of the whole thing is installing the ADB Drivers which is detailed below in step 6-7-8 in case it's all you need.

Step 1: Download Android SDK Manager (There are lots of stripped versions that might work but for tutorials sake we'll use the whole thing).

Step 2: Download Cydia's Impactor (Cydia's Impactor home page in case you are interested in reading a bit).

Step 3: Install both software previously downloaded (The Android SDK Manager doesnt have an installer, it will unzip and work from that directory, it's probably better if you unzip it into an easy to access path but it's up to you, for tutorial we will use C:\ASDK\ ).

Step 4: Open Android SDK Manager, select from the list and install ONLY* "Android SDK Platform-tools" and "Google USB Driver" (* Only as in this are the only things we actualy need, if you need at some other point or are interested in tinkering you are free to do so).

Ok so here we start with the sort-of-hard part, making our computer connect with our Slate 7 through ADB, to do this you need to...

Step 5: Open a command terminal (Windows button + R to open a run window and type CMD to open a terminal).

Step 6: Go to C:\Users\USERNAME\.android\ and type within the terminal:

echo 0x03F0 >> adb_usb.ini

Step 7: At this point you need to get back to an explorer window and get to C:\ASDK\sdk\extras\google\usb_driver\ (Or wherever you unzipped it), there you will find a file called "android_winusb.ini", open it and add at the end the following:

; HP
%SingleAdbInterface% = USB_Install, USB\VID_03F0&PID_5E1D
%CompositeAdbInterface% = USB_Install, USB\VID_03F0&PID_5D1D&MI_01
%CompositeAdbInterface% = USB_Install, USB\VID_03F0&PID_601D&MI_01

Step 8: Open Windows Device Manager and you will see your tablet as "HP" with a yellow warning icon, right click it and check update software, then click look for software in the computer, then click on choose driver from a list.

Once you do this you will see an icon "use disk". Explore your way to C:\ASDK\sdk\extras\google\usb_driver\ and choose "android_winusb.ini" file.

The first option you will see is Android ADB Interface, so you pick next, it will warn you about installing drivers from unkwnown sources you keep saying yes until it's done.

Step 9: Go back to your CMD terminal and get to C:\ASDK\sdk\platform-tools\ , this is where ADB.exe is and type in the following:

adb kill-server

adb start-server

adb devices

If everything worked as expected you will see a device listed, this is your Slate 7.

Step 10: Now open Cydia's Impactor tool, you will see a small window with a default command on screen which is the following:

# drop SuperSU su to /system/xbin/su

Just click Start next to it aaaaand you are done!

Just open an app like Titanium Backup which needs root to see if it worked.

This method is simple plus you don't have to download anything chinese or unnecesary software into your computer, the tutorial is really long because I tried to be as detailed as posible but in the end you shouldnt take more than 5 minutes (The downloads might take a bit longer though for the SDK), I would take screenshots of the process but my computer runs on a Spanish version of Windows (The same reason why you might see things with different names I was just trying to guess the device manager label part).

If you have any question feel free to ask and if it worked for you a thanks would be awesome so more users will try this.
