Moto G Failed KitKat 4.4.2 Update
I previously unlocked the bootloader and rooted my Moto G. The kitkat update was released today, when i tried to update the phone powered off and said something like "Updating...". The bar got to about 60 pct and said "Error!", then the phone rebooted, and after a short time a pop-up said, "The Update Failed!".
I tried resetting my phone, unrooting my phone, same problem. I tried using Motorola Device Manager to update, and it said
"There are no updates for your device at this time.
Current Version: 14.81.1.falcon_umts.Telus.en.CA".
SOLVED (This only works if you have an unlocked device):
Step 1: I Downloaded My Stock Firmware here: http://sbf.droid-developers.org/phone.php?device=14
Step 2: I Downloaded fastboot and mfastboot (you need both) from here, https://docs.google.com/file/d/0B_ni...BfbXFlUk0/edit
Step 3: I unzipped my stock firmware so all the files were in the ElementalXDesigns-MotoX-Tools folder
Step 4: I installed the drivers for my Moto G, including Motorola device manager, not sure if that was needed though
Step 5: On my Moto G i went to Settings, About Phone, and tapped Build Number 7 times until i became a developer
Step 6: I went into the newly found Developer options and turned USB Debugging on, I connected my USB cable to my PC, and a popup on my phone asked me if i wanted to allow access to my PC, i allowed it
Step 7: I held shift on my keyboard and right-clicked inside the ElementalXDesigns-MotoX-Tools folder and selected [Open Command Window Here]
Step 8: I typed in the command window "adb devices" to check if my everything was functioning properly and my device was connected, the response in the command window was
List of Devices attached
Step 9: I typed in the command window "adb reboot bootloader" to boot my phone into fastboot
Step 10: I opened the .xml file (using notepad or internet explorer) that i previously extracted from my firmware package, in my case
It had steps listed under <steps interface="AP"> which i put in to CMD (If you dont see it like this, open it with internet explorer)
Example first step was: <step operation="flash" partition="partition" filename="gpt.bin" MD5="85bb9a8cc1747d87547c4a77aa389667" />
So in the command window i typed "fastboot flash partition gpt.bin"
For every command you have to type fastboot before you type the step operation, partition, and filename, EXCEPT for the system.img ones or one, for those instead of typing fastboot before, you type mfastboot, example:
<step operation="flash" partition="system" filename="system.img_sparsechunk.0" MD5="e472e9ffb293637081b4c424eb833ebf" />
So i typed in my command window: "mfastboot flash system system.img_sparsechunk.2"
Step 11: Once i was done inputting all of the commands in order, i rebooted my device, i tried the update like normal, and it worked!
