    04.10.01 is not supported by ultrasnow. You need to use stuff like Gevey in order to unlock your phone. Welcome to the forum.

    Unfortunately I can't help you to get any Gevey also can't help you to install it, you do it, and you do it at your own risks. Gevey is a sim card you can purchase from Amazon or bestbuy etc... Google to know more about it, I personally don't have any experience with Gevey.
