installation

###################### ##1) enable fastboot At first you have to unlock your Device to install Firefox OS.

"Fastboot mode is important because it is the first step in flashing custom updated and newer builds of Firefox OS/B2G on our phones. Fastboot is the first step because it is the mode that will actually allow us to flash new images (like custom recoveries new Firefox OS versions) to our devices in a mostly safe manner. Access to fastboot mode simply means that our device is "unlocked" and ready to hack and modify!"(quote from source)

1] Enable the DEVELOPER-MENU and ADB-DEBUGGING on your phone, Settings > Device Information > More Information > Developer Menu switch.

2] check adb knows device
