General Warning, read before doing anything to your tablet:

Whenever you try to do anything to your system ALWAYS back up everything since there is always the chance that something might go wrong.

If something goes wrong you have to download and install the boot images from HP support, HP Slate 7 2800 restore image and HP Slate 7 4600 restore image, the install instructions are in the same page in "How to install".

Some users have had problems with the alternative rooting method using Bin4ry's tool, since it is some I will asume it is something someone is not doing correctly, because other users with the same slate model have been able to root, if it is your case where you can't actually root post here I'll try to help you in any way I can.

To end this sort of disclaimer, my Slate 7 is the model 4600 so I'm not actually able to try the method with other slate models, anyhow other users have had no problem but as always this could be your case and I'm not responsible in any way if you brick your device.

Cydia's Impactor tool has been updated and it's working with all versions of the roms (Confirmed by users).

Bin4ry's rooting tool has been updated, chances are it's more friendly user and won't throw any errors, up to you to try it out.

Just as a side note, the screenshots below are just for reference, they are not the same drivers/devices, they are only meant for you to know where to click.

Step 1: Download Tool Package (this is an old package, the drivers in the package works but you NEED TO ALSO DOWNLOAD Cydia's Impactor (Link to home page in case you are interested in reading a bit) and Googles ADB Drivers with a little modification in the ini file so it installs the driver for our HP Slate 7 tablet). If your Slate 7 model is 2800, you have to also download Moborobo that will find and install the drivers for you. I've received messages from users who have had both good luck and no luck installing the drivers, this must be dependant on your operative system and administrative rights, I did all this steps on a Windows 8 64bits machine with administrative privileges.

Download latest Cydia's impactor tool from the link above. The one in the package won't help you if you are trying to root v9 and above.

Step 2: Unzip the package anywhere you like, meanwhile go to your tablet and set it to USB Debugging.

YOU MUST SET IT ON USB DEBUGGING MODE, else nothing that you try will work.

Step 3 OPTIONAL: Just in case if your computer doesnt realize there is a device connected you need to copy the file in "\.android\adb_usb.ini" over to your user path "%USERPROFILE%\.android\" and reboot the computer (Just in case it wont recognize a device as connected).

Step 4: Now open the computers Device Manager and you will see something similar to this picture

Step 5: Right click the HP Device and choose to update driver, search for drivers in the computer (2nd option), then "let me pick from a list of device" as follows:

Step 6: Next click in "have disk" and navigate to where you unpacked the file downloaded earlier and choose the ini file.

Pictures for reference only.

Step 7:All you have left is 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!

(PS: If this worked you are done, skip Step 7B. If you were unable to root your device try Step 7B)

Step 7B (ONLY IF Cydia's tool did not work): Warning: I've received messages from some users that this exploit has left them on bootloops, this method is tested on the 4600 model, if you have another and it works please do post your results, if you have problems all you have to do is download your model ROM from HP support and boot it through your microSD card to restore factory settings, also check in Bin4ry's thread for information if it is your case, if you find another method please do let us know ;) . DO THIS ONLY IF STEP 7 FAILED, you will have to download the following rooting tool from Bin4ry's XDA thread, execute "RunMe.bat" and use method 1 and follow the on-screen instructions (This method will reboot your tablet 3 times if I remember correctly, after 2 reboots it will be stuck in a black screen for a couple of minutes (or more, it took me around 10 minutes) this is as it pushes the files for superuser, don't panic).

You can check your build version as it's shown in the following picture.

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 (of course... as long as it hasn't been asked again and again in the thread ;) ) and if it worked for you a thanks would be awesome so more users will try

PS: My Slate 7 model is the 4600 but it should work with others slates and for that matters, with any tablet as long as the adb driver is recognized.

PS2: If you could upload the package into a new mirror that might help more people.

PS3: Updated to March 16th 2014.

PS4: I just realized the screenshots facilitated by another user have been deleted, will try to find new ones.

PS5: If this helped you, please do thank, this way more users will benefit from it.
