Requesting help in unbrick wdtv live streaming

[Prad]

Recently my wdtv live streaming stopped working. It stops at logo screen and looks like it's bricked. I found somewhere that reflashing firmware can fix it. Below is my wdtv pcb photo please help in identifying serial com port pins. http://imgur.com/7tlhlIE

Looks like the pins next to the battery. Here's what they do: http://wiki.wdlxtv.com/WDTVLiveSerial

Note that serial console is password protected. Also, try a reset to factory defaults when booting (press and hold the reset button while booting for ~30s).
