I cannot be held responsible if there is a problem with your modem after the update. I put this page together to make flashing your modem as easy as possible, but I cannot control this process for you. Either wait until you are more familiar or ask a friend who has a better grasp to do this for you. There is a very real danger of wrecking your modem if this process is done incorrectly. That means that the firmware on those sites is in beta testing.
Beta software is software that is unfinished and is believed to contain bugs.
If that sounds too risky, wait for the finished version. If you have more links for me to add, email me here.
