none are patched.. what they have did is that they have changed the value of the codes..
910 (which was 3K coins for premium gold) has been changed now to 30K coins, so those who use it without knowing will loss alot of coins..
other all codes work, like the one with 5K coins premium gold (305).. and code for 35K which gives u 12 rare players.. what is different is that in that old one u wouldn't have lost anything as if u had discard everything u would have got around 2.5K.. but now in these codes u can loss alot if u get shitt players.. but someone are making good coins with the code for 12 rare players for 35K (like if u get Robben, Augero)..
35K 12 players, all rare = 3411
this works decent for some players, that doesnt mean it should work good for u too.. overall its all about luck
