I downloaded two pieces of software to determine the codes. I tried two codes from the first list but got 2 code errors. I didnt try any from the other list as in order to generate codes I need to select one of GTCL-001, V1, V2, Griffin(old), Griffin(new). I have no idea what these mean. Please help. My details are below. Thanks. Nokia 6230 UK t-mobile (I believe the code is 23430) IMEI 353767003461073
