Don’t try this one any other device!
1- Install the Moto X 2014 drivers.
2- Install the ADB drivers.
3- Download the RSDlite software and AT&T Moto X 2014 5.1 update file from the downloads section above.
4- Extract the firmware file using a free software like 7-zip, into a separate folder preferably.
5- From the extracted files, open the flashfile.xml file, and then remove the line(s) which have getvar command. Usually it’s as given below, but if there are more such lines, delete them too.
6- When done, save the file and close it.
<step operation = “getvar” var = “max-download-size” />
7- Remove the line(s) containing getvar text from another file, servicefile.xml. Save and close the file when done.
8- Reboot your AT&T Moto X 2014 to fastboot mode. Do this:
•Power off your device first.
Press and hold Power + Volume down together for 5-6 seconds, and then let go of buttons. You’ll enter bootloader mode, aka Fastboot mode. You’ll see
•FASTBOOT AP written at top.
•Extract the RSDLite6.2.4.zip file to get the RSDLite6.2.4.msi file.
•Install the RSDLite software by running the RSDLite6.2.4.msi file — double click on the file to start the installation.
9- Open the RSDLite software now.
10- Connect your device to PC now, with USB2.0 cable. Avoid USB3.0 cable when using RSDLite. You should receive Fastboot <device codename> text under the model coumn of RSDLite, in row one, as shown below.
11- On RSDLite, click on the 3-dot button and select the either servicefile.xml (btw, use flashfile.xml if you intend to completely wipe off the device).
→ Both files instruct RSDLite to flash the firmware files on the device, but servicefile doesn’t asks it to wipe the data of the devices. Thus if you use flashfile, your device’s apps, games, contacts, etc. will be deleted, while in case of servicefile, your data remains.
→ We recommend you to use servicefile, and in case device gets stuck at boot logo, then simply enter recovery mode (select it from fastboot mode) and then do a factory reset yourself, and then restart. Should be fine!
12- So, with device connected and showing up in RSDLite, and servicefile/flashfile selected, click the start button to begin flashing the 5.1 update on your Moto X 2014.
13- That’s it. When RSDLite is done flashing the 5.1 firmware, the device will restart automatically. Give it ample time to reboot, like 10-20 minutes.
→ Take care to not remove the cable until the device has restarted completely. Close the RSDLite only after that.
To confirm the 5.1 update’s installation, go to Settings > About device. You should see the info as given below.
