Motorola’s Droid X protects itself from hackers by self destructing

Motorola’s next flagship smartphone, the Droid X on Verizon, is set to go on sale on Thursday — but you might want to think twice if you’re hoping to hack the device.

Motorola has apparently locked down the phone to the point where any modification attempts — including “rooting” the phone to install unauthorized apps, or changing its firmware — could render it completely inoperable (or “bricked”). The only way to fix it is to return the phone to Motorola, reports the Android fansite MyDroidWorld (via MobileCrunch).

The company is using a technology called  eFuse to secure the device. It runs when the phone boots up, and it checks to make sure that the phone’s firmware, kernel information, and bootloader are legit before it actually lets you use the device. Here’s MyDroidWorld’s explanation:

If the eFuse failes to verify this information then the eFuse receives a command to “blow the fuse” or “trip the fuse”. This results in the booting process becoming corrupted and resulting in a permanent bricking of the Phone. This FailSafe is activated anytime the bootloader is tampered with or any of the above three parts of the phone has been tampered with.
