Flashing Cisco Meraki MR18 with OpenWRT firmware ?

I had this question after viewing Using Cisco Meraki for home use after the license expired ?.

Hi All,

Can anyone here please explain to me what does the below steps means:

UART adapter wired to the MR18 (speed is 115200). Pinout (left to right): VCC/RX/TX/GND ?

Because behind the Meraki MR 18 I can only see power port and also the Gigabit Ethernet port. no COM or serial nor USB port.

How to back up the Official firmware before overwriting it with the OpenWRT ?

Thanks in advance.

@Craig: does this means that I can use any USB drive to load the firmware to the USB port within the Meraki MR18 device ?
