I check your order, for new 4d chips you bought together with this CBAY programmer, it is the 4D chips specially used for CBAY programmer. For old chips you bought, it is the 4D chips used for CN900 programmer, they are different chips. CBAY cannot use 4D chips which is used for CN900. CN900 as well.
