Seems like you soft bricked your phone,is your phone i9100g? Or just i9100? Its very crucial as i9100g has no custom roms at the moment,flashing i9100 roms(all custom roms are for i9100now) will soft brick your device. try hold down power button till it shuts down completely,then go into download mode. Need to tell me if its a g or non g sgs2 to tell u next step

No wonder,flashing non g custom rom on g version will brick your device. Pullout battery,put in battery,boot into download mode,connect ur device to pc once into download mode,open up odin, download the kernel from here http://forum.xda-developers.com/showthread.php?t=1327509 download v1.1, click pda,select the file you downloaded then done

No probs,remember to notify us if it works

Uh,so before you send to sc,yours was a non g model? Then after you sent it to sc,they changed the motherboard and it became g version? G model also has its pros,like it gets official firmware updates faster,less heat,and better battery life. If you buy g model,it will state it behind the box.
