Judging from your thread in Help, you have a Wifi connection.
Why not GTS one?
Or, you could use the GTS' glitch. Upload your kadabra leave it there while you search the GTS for something to trade for. Trade for something, and the game thinks, for some reason, you traded your stored Pokemon (but it will still be there). Take it out and it will evolve.
Make sure to offer it for something impossible, like level 9 Ivysaur.
