Take it easy and mind your language. Get a cup of tea and wait.
You use the best platform, but you should use the flashing script.

The first issue I see is your USB device:
Suitable USB device not found, waiting.
USB device found found at bus 002, device address 010.
Found device RX-51, hardware revision 2204
NOLO version 1.4.14
and then later on:
Booting device into flash mode.
Suitable USB device not found, waiting.
USB device found found at bus 002, device address 011.
Raw data transfer EP found at EP2.

Care to explain? Then what about flashing eMMC first?
