    My apologies I am 72 and not the best at typing!!!! So how do I ROOT my HP 10 plus????

    Thank You


  2. Thaaank you very much!!! Couldn’t find help anywhere, but this did the trick.

  3. I posted a much simpler solution but it appears my comment was deleted for some unknown reason. No lines of code is necessary.

    If you have a rooted phone, just go to the Google Play Store and get the app called:
    SDFix: KitKat Writable MicroSD

    Install it and you’re done… you will be able to write to the SD card from any app.

  4. If you have a rooted device… just install the app called SDCard Fix and boom… you’re done…
