Seems like Motorola Photon 4G has more motives to become a good phone to buy. An XDA member already unlocked the bootloaders. All it requires are two files (a third one if you’re counting the extra step to regain root) and an ability to follow easy directions. No more hassles with an expensive $100 multimedia dock to free your device. Once unlocked, flash the included system.img file to gain the root and get going. Don’t try to flash this file until you have confirmed that your bootloader is unlocked.
