No way friend. Here you can ask as much as you want. But no one will help you in any way when it comes to the SDK, to which not everyone has the SDK. I searched the SDK also in google but no success anywhere. It is to be supposed to have only about Edonkey.
Unfortunately, available here, no debug Downgrader and unfortunately no debug firmware. Unfortunately had a free month account posted. Can you save you too, at least for the first.
Do you whant legal SDK ? you can download some package from where - [Register or Login to view links], the license is GNU General Public License (called as GPL) and GNU Lesser General Public License (called as LGPL).
