Yesterday AT&T released the NoDo update for the Samsung Focus and the LG quantum. But before this, some WP7 users were desperate to get the update, so they decided to force it thanks to a “hack”.
Now Brandon Watson from the Windows Phone team has said on twitter that further updates released won’t be able to install on the “forced” devices.
So to all of the desperate users, you’ll have to find a way around this problem. Or just reset your device.
