It's recoverable!
Hello there. Me was given a Razr i XT890. If i turn on there only the "Warning Bootloader unlocked". I try to get in Fastboot mode or any other mode but i only stuck in this window or nothing. I dont even get a Batterylogo if i load with the wall charger. I put it on my PC but nothing happens. No new Device. No ADB. Nothing. Can i rescue the phone or is it only a paperweight?
The first thing you should do is to see this video (
https://www.youtube.com/watch?v=OTzaiwj-bGw) to install libusb on your computer (if you are using Win 8 or 10 you will need to remove the signing imposition on driver installation - search for it).
The second action is to download the programs provided in this other topic of the community:

Then follow the instructions:
1 - With the cellphone turned off, connect it to the pc by the USB cable holding the camera button, when vibrate, release. (The green light should be on).
2 - Run xFSTK-SoC-Driver-Setup-1.0.3.exe and follow the instructions. (Your cellphone will probably turn on and will be locked on the bootloader unlock warning screen).
3 - If the phone has turned on, it will remain locked, then press and hold the camera buttons + volume down + power button. (It should vibrate, then release the buttons, if all goes well it will turn green).
4 - Run the unbrick.bat, when you start the prompt keep holding down the volume button of your cell phone. (If all goes well it will restart, continue with the down volume button pressed, when on it should enter fastboot mode.
If you get here and he gets into fastboot mode, CONGRATULATIONS you got it. Now just install the rom via RSD Lite. (Look up if you do not know)
Remember that your cell phone must have the bootloader unlocked for installation of the factory rom.
I do not guarantee origin, be aware that it is at your own risk
I hope I have helped!
