I have a S500i and I'm from Portugal (Europe 1) and after searching and reading about MAIN/FS files I found out that I must use these:
S500_R8BE001_MAIN_GENERIC_LY_RED52
S500_R8BE001_FS_EUROPE_1_RED52
But I also need a custom pack and I'm not sure about that. I believe I have to use the following:
HB1-06_Gen_CDA102568_10_R8A_GENERIC_EUROPE_1
Is this correct?
