If you own one of this famous device, and ever you get in a situation where your device stucks while booting, don’t panic. There is a way to recover your device by flashing fastboot files. You should consider your device as not booting if: it’s stuck at Motorola logo, or if the boot animation is playing longer than expected, or if your device is vibrating constantly after some intervals. Fastboot files are the stock firmwares leaked from Motorola which will make your device restore back to the factory condition.
Note that Motorola Droid RAZR has a permanent locked bootloader and due to this, it cannot be downgraded to a lower version of Android. Don’t try doing it or you might risk bricking your device.
If you have upgraded your device from Gingerbread to ICS, then you must flash ICS fastboot files or if you have recently upgraded your device to Jellybean via OTA then you must flash Jellybean fastboot files.
This is a risky operation. This procedure has been verified to work, and you will be flashing your complete internal memory, including the internal storage. Your SD card will not be touched though. If you fail to follow any of the instructions properly, you could permanently brick your device. Reserve this as a last option. We don’t take any responsibility if anything happens to your device.
