Which CDA is required for the following MAIN+FS?

K810_R8BF003_FS_TELEF_GEN_RED53
K810_R8BF003_MAIN_GENERIC_SM_RED53

Thanks

Which is your company or operator and in what country?

I think this custom file will work out with your FS: K810i_CDA102779_37_R9A_movistar_Spain; it has english, spanish, french and portuguese languages.
