Flight/Bootloader - Bootloader updater, WORKING - tested with PipX only (should work for all boards though).

Browse Source 
Led(LED1 different color on each board) Sequence:
1-Power On
2-Led ON for 3 seconds (you can disconnect during this time - safety measure) 
3-Led flashes very quickly while the board is being programed (because the program is stored in memory this is very fast and looks like a led glitch)
4-If all good - LED flashes 3 times with a 1sec period and turns off - you may now reboot.
4-If an error ocurred - LED will keep flashing with a 500ms period until power off
