When the firmaware update was completed I can connect, configure and use the device through its IP 192.168.1.1, all works fine.
Looking at dd-wrt config web page I realize that I've the standard version, but what I would are the voip features (Asterisk and OpenSER or Opensips or Milkfish).
So I found this dd-wrt version:
After I update the device with above firmare it doesn't boot anymore!
At this point the only way to recover the device from the wrong update is that I should connect to its serial port to try a tftp update with the previous firmware.
The problem is that I do not found the serial port. To do it I follow these pages but they referrer a differt hardware version:
Ask checho to help you. Basically I think you can find the GND and Vcc (3.3V) from the flash chip but there must be other contacts which are much easier to solder.
today I connect the serial adapter to the board with no luck. HyperTerminal doesn't shows nothing.
I've soldered the TX, RX and GND on the bottom of the board. For the VCC 3, I got it from the flash chip, I really didn't found any other source for this, all others power sources are less of 1 V.
About the failure of my try, may be the serial adapter and the serial cable I'm using.
So, can I ask you to check if this serial adapter is good for operation?

Pin 8 Flash VCC = 3.32
TX = while booting it's variable from 2.42 to 2.48
RX = while booting it's variable from 2.99 to 3.01
This is the serial output:

After last line (Resetting...) it go ahead with a new boot.
At this point I'm lost! How do I stop U-boot and getting a console to do all required by a debrick procedure (wget, tftp, and so on...)
