Before you begin with the instructions below, make sure your android device is adequately charged — at least 50% battery of the device, and your desktop PC or laptop is connected to a power source or has enough battery backup to go through the whole process below.

  STEP 0: CHECK DEVICE MODEL NO.

To make sure your device is eligible with this, you must first confirm its model no. in ‘About device’ option under Settings. Another way to confirm model no. is by looking for it on the packaging box of your device. It must be XT1053!

Do not use the procedures discussed here on any other Moto X (including the Moto X variant at Sprint, AT&T, Verizon, US Cellular and other International variants) or any other device of Motorola or any other company. You have been warned!

  STEP 1: BACKUP YOUR DEVICE

Back up important data and stuff before you start playing around here as there are chances you might lose your apps and app-data (app settings, game progress, etc.), and in rare case, files on the internal memory, too.

  STEP-BY-STEP GUIDE

Important Note: Backup important files (photos, videos, music, etc.) stored on internal SD card of your device to your PC, as flashing a stock firmware might format your phone’s internal SD card.

  1. Extract/Unzip TMO_RETAIL_XT1053_4.4.3-KXA21.12-L1.21_MR4_CFC.xml.zip on your computer (using 7-zip free software, preferably) to get the following files:
    • TMO_RETAIL_XT1053_4.4.3-KXA21.12-L1.21_MR4_CFC.xml
    • boot.img
    • fsg.mbn
    • gpt.bin
    • logo.bin
    • motoboot.img
    • NON-HLOS.bin
    • recovery.img
    • system.img
  2. Open the file named “TMO_RETAIL_XT1053_4.4.3-KXA21.12-L1.21_MR4_CFC.xml”  with a text editor on your PC, we’ll make a change in this file
    └ “Right click” on the file and select “Edit” from context menu.
  3. [VERY IMPORTANT!] Look for the following line in the file, then select and delete it. Once deleted, save the file by pressing “Ctrl+S” on your PC.
    <step operation="getvar" var="max-download-size" />

    Remove this line

  4. Make sure that you’ve removed the above mention line from “TMO_RETAIL_XT1053_4.4.3-KXA21.12-L1.21_MR4_CFC.xml file and then saved the changes. It’s very important to do this, otherwise you’ll get the following error while flashing the firmware failed flashing process. Unknown fastboot command. (getvar)”
  5. Double-click/Run the “RSDLite6.1.5.msi” file that you downloaded from above to install RSD Lite software on your PC. Once installed, start/open RSD Lite on your PC, it should look like this:
    RSD Lite
  6. Now boot your Moto X into bootloader mode:
    1. Power off your device and wait for 5-10 seconds until the device is fully switched off.
    2. Press and hold Volume Down + Power button together for a few seconds and then release them to get into bootloader mode
  7. Once your Moto X is in bootloader mode, connect it to your PC with a USB cable. The RSD Lite screen should show your Moto X in Port No. 1 with “Fastboot ghost S” as model name. Check the screenshot below:
    RSD Lite connect phone
    └ If your phone doesn’t appear on RSD Lite screen or if its status isn’t shown as “Connected”, then it means you don’t have proper Moto X drivers installed on your PC. Get them here → Moto X Drivers
  8. Click on the three dots button RSD Lite three dots button on RSD Lite and select the “TMO_RETAIL_XT1053_4.4.3-KXA21.12-L1.21_MR4_CFC.xml” file that we edited/saved in Step 3 above. Your RSD Lite screen should look like this after selecting the file
    RSD Lite select file
  9. Click the “Start” button on RSD Lite to begin flashing the selected firmware file. Once started, you can see the process in action on the bootloader screen on your Moto X.
  10. When the flashing process is finished, your phone will automatically reboot.

NOTE: RSD Lite may get stuck with “Rebooting” under the Result column but that’s okay, if your Moto X has successfully rebooted then it is safe to disconnect the USB cable.
