How to Unbrick or Restore US Cellular Moto X XT1055

Looks like you just got unlucky in your little Moto X hacking adventures — that is, little things like rooting, custom recoveries and custom ROMs — and now, you have a bricked device in your hand.

Well, what we can do now is try to restore your Moto X back to stock using a firmware so that all bad partitions on the device are fixed and it doesn’t bootloops and restarts normally.

And well, depending on what you were trying to do, and more importantly how, it could either be soft-bricked or hard-bricked — in latter case, as sad as it is, you maybe out of luck, man!

What’s Hard-brick and Soft-brick?

Even though rare, and when you are like set to be doomed, your Moto X might get hard-bricked. In which case, the Moto X won’t boot into bootloader mode — it won’t respond to key combinations you are trying to make it to boot normally or to bootloader or recovery mode.

Hard-brick results in one dead Android device. Yes, it’s sick, and worrying. You may have to look for a JTAG service locally; the person with good knowledge of that may be able to revive it.

Hard-brick is rare, it may happen only when power supply gets disturbed of computer and/or Android device when something is being installed/updated on the device. Or, when you totally mis-do things totally recklessly. That’s why you have to be very careful with even the easiest steps.

Let’s see soft-brick now. Normally, a brick is a soft-brick, which means your device isn’t completely dead, that it is just not able to boot normally and gets stuck somewhere. And, bootloader mode is working.

How to identify bricked Moto X?

If your Moto X can boot into bootloader mode, then it means it’s a soft-brick. If it cannot, then it’s hard-bricked.

Cases of soft-brick:

Bootloop: Your Moto X is not restarting properly and gets stuck at logo, and reboots again and again on it. Mostly occurs when you flash something bad.
Corrupted but working: Your Moto X can’t power On, but is entering the Bootloader mode and/or Recovery mode on pressing the key combinations. That is, it’s responding to key combos, at the least.
Any other case: As it doesn’t matter what happened, as long as you can access Bootloader mode using the key combos specified in the unbrick Moto X guide below, you’re good — no reasons to worry!

Solution?

Just install the stock firmware using the guide below and your Moto X shall be up and running coolly soon enough! you must be able to enter bootloader mode using the key combinations specified in the guide below.

Cases of Hard-brick:

Well, if you can’t enter bootloader mode using the key combinations specified in the guide below, you got a worry — your device is hard-bricked. You can’t repair it yourself unless you are able to reboot it into bootloader mode.

Solution?

Your best hope is JTAG: find a local service provider who can use the JTAG for you and revive your dead hard bricked Moto X. You can use Google to buy JTAG and try it yourself but we don’t recommend it at all, at it requires the skills of a knowledgeable person in Electronics.

Let’s see now how to unbrick or restore or fix a bricked Moto X.

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:

└ 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
Click on the three dots button on RSD Lite and select the “USC_XT1055_4.4.2-KXA20.16-1.27_CFC_1FF.xml” file that we edited/saved in Step 3 above. Your RSD Lite screen should look like this after selecting the file
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.
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.
