Motorola officially releases their guide to unlock boot loader.But before unlock bootloader please keep in mind that you are voiding their terms and Motorola no longer responsible for any damage caused due to this.

Review the risk

In case you didn’t know, bootloader is a little bit of code that tells your device’s operating system how to boot up. Motorola has done the work to make sure your device has a fully optimized, certified and tested version of Android. If you are a developer, unlocking the bootloader will allow you to customize your device, but keep the following in mind:
  • You will lose all media and content on your device and will need to reinstall all applications downloaded from Google Play.
  • Applications may not work anymore.
  • You may lose encryption support.
  • You may lose some key functions like telephone, radio, and audio playback.
  • You could cause permanent/physical damage to your device.
  • Unlocking your bootloader will not change your device subsidy lock status


  • Unlocking your bootloader is not for the faint of heart. Unlocking your device and installing your own software might cause the device to stop working, disable important features and functionality, and even make the device unsafe to the point of causing you harm. Neither Motorola, nor your wireless carrier or retailer from whom you purchased the device, will be responsible for such damage, so please do not unlock or load any software unless you know what you are doing.
  • You have only yourself to blame. Unless you have a Developer Edition device, once you get the unlock code, your device is no longer covered by the Motorola warranty; in other words, please don’t blame us if things go wrong, even if they appear unrelated to unlocking the bootloader.
  • The law still applies. You still need to operate your device in compliance with all applicable laws, rules and regulations prescribed by the FCC, and any other governmental agency for that matter. Your wireless carrier may prohibit unlocked devices from operating on their network.
  • And now a word from our lawyers. Finally, in order to unlock your device, you need to agree to important legal terms, which can be found on the next page. Agreeing creates a binding legal agreement, so be sure to read them carefully.
