as you can see

first enable telnet if you're on win 7 * disabled by default on win 7 type telnet on cmd press o to open new connection point to 192.168.1.1or 192.168.1.254 or your router ip login with default user...

i succesfully reset it via telnet, i already try to upgrade,,but the Telkom firmwire is rejecting new binaries...always fail at 30 percent
