How to Install Stock Firmware on Moto Maxx XT1225

Android, the most popular operating system for mobile devices, is best known for its capability for customization, flexibility and vast development community. The OS allows you access to millions of apps but the real joy of being an Android user lies in the very sense of freedom and possibilities that comes through root privilege. By gaining root access on your device, you can take control of the system files and modify them to achieve the desired goals.

Even if you are not an advanced user, there are hundreds of people working selflessly to help you with customizing your device or solve the issues you might have in using it. Indeed, rooting and flashing custom recoveries, kernels, mods, patches and ROMs add a hell lot of adventures to Android experience!

Since involving in custom development activities void the warranty of the device and expose it to risks, you must know the way to restore your device to stock. Sometimes, flashing the stock firmware back might prove to be a lifesaver! If you want to unroot your device, or recover it from a bootloop, or want to get OTA updates, or make a warranty claim, you must restore it to stock.

Android is blessed with hundreds of OEMs who use the customized versions of OS on their devices. And therefore, there’s no universal method for installing the stock firmware on Android devices. The tools and methods differ from OEM to OEM. When it comes to Motorola phones there are 3 ways to flash the stock firmware on them— using a tool called the RSD Lite, using ADB and Fastboot commands to push the firmware files to the device, and by running the .bat file provided with the firmware.
