you must ENSURE that you have Wi-fi connection, and should probably test this with a pokemon you don't like first. Step 1 Go to to the Global Trading Station (GTS). And Log in. Step 2 Once your in the main menu of the Global Trading Station. Go to "Deposit". Put in the pokemon you want to clone. Step 3 Deposit the pokemon into the GTS, make sure you offer it for a Pokemon that nobody would trade for it. Cause if someone trades for the pokemon in the GTS, Then the whole process is ruined. Step 4 This is the hard part. It should even be considered as the main step into duplicating your Pokemon. After depositing your Pokemon It will now say: "Checking GTS's Status...." On the right of that message, a clock should be going around. On the eighth spin, simply turn the DS off. It doesn't have to be exactly 8 spins! Your goal is to shut your DS OFF 1 spot before the loading is complete. Step 5 Turn your game on. You should get a error message: "Your file has been corrupted. The previous file will be loaded" Don't worry. This is normal. Step 6 Go back into the GTS, and you should have one in your Party, and GTS slot. Step 7 Logout and save.
