ASUS updated today its FonePad through a new firmware, namely the 3.2.3 version, and even though no changelog is available, I assume it may improve the device’s overall performance and stability.An important aspect that you should take into account would be that every one of these Android devices have installed a specific SKU (stock-keeping unit), and switching between SKU versions isn’t supported by the upgrade procedure.
Moreover, installing a wrong one (or even an earlier one) may not be successful, and might lead to an update failure or even device malfunction.
So, if you don’t know the stock-keeping unit of your ASUS FonePad, go to “Settings,” select “About Tablet,” and afterwards “Build Number.”
There you should be able to read the device’s SKU that consists of the letters before the first underscore line. To be more accurate, if the build number is WW_epad-9.X.X.X._2012xxxx, then your SKU would be “WW.”
That being said, follow the link below, and from the list, choose the one that best describes the SKU of your FonePad.
