Updating the Android Operating System on Your HP Slate 8 Pro Tablet (Android)

This document applies to HP Slate 8 Pro tablets with Android 4.2/Jelly Bean operating system.
HP provides OTA (over-the-air) updates for the Android operating system on your tablet. When your tablet is connected to the Internet, updates download automatically and prompt you to install. If you received and installed the updated Android 4.4/KitKat operating system over the air, you do not need to use this document to update your tablet.
If needed, use a microSD card to manually install an updated version of Android on your tablet, using the steps in this document. Installing a new version of Android does not destroy the data or settings on your tablet.

Before you begin

Before starting the Android update process, you need the following:
  • MicroSD memory card: You need a microSD card with 1GB or more capacity. All data is erased from the card when you create the software update media. Back up any files currently stored on the memory card before you begin.
  • MicroSD-to-SD memory card adapter and SD card reader: You need a memory card adapter and card reader to create the update media on your computer.
  • Access to another computer: You need a computer with Internet access to download the software image and create the Android update media.

Creating the Android update media

The update media is a system file (called a "software image") stored on a microSD memory card. After the update media is created, use the memory card to load a new version of the Android operating system on your tablet.
Use the steps in this section to create software update media for your tablet.
  1. Insert the microSD card in the SD card adapter, and then insert the adapter into the SD card reader in your computer.
  2. Format the microSD card using the FAT32 file system.
    note:
    If you need instructions for formatting the card, search the Internet using the term "format memory card fat32" plus your operating system (for example, search for format memory card fat32 Windows 7).
  3. If prompted to enter your model number, do the following:
    1. Enter the model name for your HP tablet (slate 8 pro).
    2. Click Go.
    3. You may need to select a product number from a list before you can access your product support page. If so, select your product number from the list.
    4. From your product support site, click Drivers.
  4. On the Drivers page, select your operating system from the drop-down menu, and then click Next.
  5. Click the plus (+) sign next to Software - Solutions.
  6. Find the most recent Google Android KitKat Restore Image, and then click Download.
  7. Save the update.zip file (software update image) to your microSD card. Do not unzip or rename the file.
