## Modification
### Rooting

Developers have found means to root the device, which provides access to hidden files and settings, making it possible to run apps that require deep access to a file system or make changes to your device. For instance you can use apps to back up or restore all of the apps on your device. Numerous websites offer downloadable software and step-by-step directions to do-it-yourselfers.

### Third-party apps and firmware update 1.4.1

When the Nook Tablet was first offered, users could install third-party apps. However, days before Christmas 2011, the forced over-the-air "firmware update from Barnes & Noble for the Nook Tablet and Nook Color — 1.4.1 — close[d] the loophole that allowed users to sideload any Android app and also [broke] root for those who’[d] gone that extra step to customize the device.

### Alternative operating systems

In addition to the stock firmware provided by Barnes and Noble, the Nook Tablet can run free, third-party, alternative Android operating systems such as CyanogenMod. These replacement distributions typically include advanced tablet features such as overclocking, a regular Android tablet interface, and access to competing app and content stores such as the Google Play and Amazon Appstore. Alternative operating systems may be run either from the eMMC chip or via a microSD card, which allows multi-booting. When the card is in the slot, the Nook Tablet will start from the operating system on the SD card. Otherwise, it will boot from the eMMC.
While much of the replacement firmware for the Nook Tablet is available via free downloads, and instructions are readily available to install to either external microSD cards or internal storage, pre-installed versions on microSD cards are also available for sale by vendors who have tested and developed error-free versions and instructions for the free software and offer it for a price and in some cases, along with customer service and user forums.
