Sounds to me like you have bricked your phone when you unlocked the bootloader did you use the Motorola website because unlocking the bootloader should not brick you're phone trying to root it can brick it if you're not careful
Sent from my XT890 using xda app-developers app
Apparently, the same happens to me. But, in my case, I was flashing the root files for JB with adb and the power got down in the middle of the process.
Now the phone is freeze in the unlocked bootloader warning and resets after some seconds.. eternal loop.
• If I press Power + Vol Down, the phone resets but don't get in the fastboot menu.
• Adb doesn't recognize the device / not even RSD Lite (All drivers are installed)
Is there any hope?
