Instruction to flash stock firmware on Moto X 2014
1. Enable ‘USB Debugging’ on your phone. To do so, go to About phone -> tap on ‘Build number’ several time -> Go back -> Developer options -> Enable USB debugging.
2. Turn off your phone and then press and hold the Volume Down + Power buttons simultaneously for a few seconds. This will boot the phone into bootloader mode.
3. Now, connect your Moto X to your PC via USB cable and go to the folder where the Minimal ADB is installed (C:\Program Files (x86)\Minimal ADB and Fastboot). Launch a command window from there (Press Shift key, right click and select ‘Open command window here’), then issue the below command.
[Your device should detect and list. If not, it means correct fastboot drivers aren’t installed on your PC. Follow this guide to download and install adb drivers on your PC]
4. Unzip (use 7zip) the downloaded firmware xml and save all the content into the Minimal ADB installation folder (
C:\Program Files (x86)\Minimal ADB and Fastboot).
5. Also, unzip mfastboot zip and move its files where you have saved the firmware files.
6. Open the ‘flashfile.xml’ with Notepad or WordPad and you will see a list of files. The file tells you how to flash the files into your phone (For example, system system.img_sparsechunk.0 and the like)
7. Open a command prompt inside the Minimal ADB folder and issue all the commands one by one (for example, see below commands. There might have few differences in your commands).
