What i've done wrong ?
1. i've launched Mystery Machine Spoofer and dumped code into Hans folder at sdcard root
2. i've launched ctr-httpwn
3. i've launched Hans with no region and language FR in settings, and "code to sd" set to yes
4. Launched Pokemon Y (digital copy) through Hans
5. When i try to get a gift by Internet i've got a chromatic xerneas once, and if i try to get gift by a code, it hang at internet connection, and i should leave by L+R+down+B
Did you copy the user_config.xml file? That's the only thing I see you are missing
