I used this method with the following hardware and software:
- Moto X (XT1058) Movistar.en.CL original with LOCKED bootloader - MacBook Air with MDM (Motorola Device Manager) installed - 4.2.2 ROM file: fastboot-ghost_retbr-user-4.2.2-13.9.0Q2.X-116-LCX-35-36-release-keys-cid12-Brasil-BR.tar.gz (EXTRACTED ON DOWNLOADS FOLDER) - 4.4.0 ROM file: Blur_Version.143.44.8.ghost_row.Brasil.en.BR.zip THE FILES BELOW WERE UPLOADED BY SOMEONE ELSE. SO DON'T BLAME ME IF THE LINKS ARE NOT WORKING OR YOU BRICK YOUR PHONE.
The process is pretty simple:
First, you “convert” your Moto X to Brasil Retail version (Flashing the 4.2.2 ROM) and then you upgrade via “sdcard” to 4.4 ROM.
The whole process takes about 20 minutes and I preserved my info and apps but a wipe is recommended in XDA & MotoXBrasil forums.
####Goint to Retail Steps:
- Put your Moto X in “fastboot” mode (With the phone OFF, press and hold the Volume Down & Power Button and then release de Power Button).
- Connect your Moto X to your PC vía USB.
In Linux & OS X go to Terminal and enter the following commands:
cd Downloads/fastboot-ghost_retbr-user-4.2.2-13.9.0Q2.X-116-LCX-35-36-release-keys-cid12-Brasil-BR/ bash flashall.sh
(In Windows open the Files Explorer go to the extracted folder and execute flashall.bat)
Wait until it finish.
####Updating to KitKat Steps:
- Connect your Moto X to the computer as a media device.
- Put the Blur_Version.143.44.8.ghost_row.Brasil.en.BR.zip file under the root folder of your phone
- Go to Settings->About->Available Updates
- Accept all and wait
- You’re now using KitKat without losing your Warranty.
