Thanks for helping but no luck getting odin and phone to connect. Have tried 5 different versions of odin but nothing.
Will just send this back and fingers crossed they fix it. Otherwise, I will just go back to my S2 and lick my wounds.
EDIT: Managed to get it to connect. I flashed MGG and still have wifi issue - just won't toggle to on position. Am I ok sending this back or do I need to hide the fact I used odin just now?
