Sorry having trouble finding hutch_1 custpack please advise.

is this right,will flash with

K770_R8AB001_MAIN_HUTCHISON_HK_VI_RED53.rar
K770_R8AB001_FS_HUTCH_1_RED53.rar

But I need to use the Custom pack K770i_1202-4418_R7A_3_United_Kingdom for three settings is this true?. What FS and Main will match this cust pack.
