    [link|https://www.android.com/history/#/marshmallow|Android] devices, particularly the developer-friendly Nexus models from Google, are especially suited for unlocking and tinkering with.

    The Android OS, based upon Linux, is modular enough to allow replacement and upgrading of particular components of the system: bootloader, recovery, radio software, and both the underlying operating system and the user interface. Just as you can replace the default home screen/launcher app with one you like better, you can run a different ''build'' of the open source Android operating system (AOSP) for improved performance or bleeding edge capabilities. These are called ROMs.
    Even without switching out the core OS, you can use a customized ''recovery'' partition. Team Win (TWRP) and ClockworkMod (CWM) are the most popular third party ''recovery'' replacements, and are available for many Android devices. They provide advanced maintenance functions, including the ability to install ''root'' apps that let the user and apps perform functions as the system user.
    === Tools ===
    The basic tool for working with a Android device is the '''***Android Software Development Kit'''*** (SDK), which includes tools like ''fastboot'' and ''adb'' (Android Debug Bridge). There are third party "lite" versions of the basic tools for most operating systems. Some GUI tools take the complexity out of using command line tools to perform common operations, but these actions are no less powerful.
    == Warning ==
    Unlocking, flashing, rooting your device may void the warranty. You are also at risk for "bricking" (rendering inoperable and irreparable) your phone or tablet. You assume full liability and responsibility for attempting to follow any of these steps.
    Some applications will not work if a device has been unlocked or rooted. E.g. ''Android Pay'' now detects if the system has been compromised this way in Android 6.0, and will refuse to work for you.
