''locking this thread as duplicate, please continue at [https://support.mozilla.org/en-US/questions/1014768 /questions/1014768]'' I bought the device for developing purposes and just got it today. I am a US user by the way. I followed the directions that are listed here for how to root the device and unlock the bootloader, however, the directions do not work. I now have a rooted terminal using adb shell, however, when i reboot to the bootloader and run fastboot devices I get nothing, and no other fastboot command works. This is absolutely ridiculous. I bought the phone from the ebay site just this week using the link here on Mozilla. I've even synced and built B2G for the device. But I can't unlock my bootloader? Defeats the purpose of "open" and makes me regret my purchase. I would appreciate some prompt help in this matter.
