  • This is a nice and easy to follow guide, I came here after googling on how to root the HP Slate 21 (all in one android pc) but this seems to be about another HP device. Is the title correct or does HP have two device with same/similar names?

    • Since I cant edit my posy Ill reply to it, I realize now that this is about the all-in-one pc hp slate 21, I got confused when I saw the picture with the HP smartphone.
      Was just wondering, does the install of TWRP recovery or supersu wipe the pc or does all my installed apps stay intact?

  • Thank you very much for your reply Himalaya. Now I am ready to install TWRP and root my slate, but after reading through your post again I see that there are no download links for the mfastboot driver zip file. Any chance for a reupload of the mfastboot? I tried to google for it but cant seem to find mfastboot driver for the HP Slate. I would be very grateful if you could point me in the right direction to a download of this driver.
