Help CDA for My K790a

[SeaMonkey]

ok ive flashed my phone with

K790_R6BC002_MAIN_GENERIC_EV_RED52.mbn
K790_R6BC002_FS_AMERICA_2_RED52.fbn

i selected a cda in xs++ that was in the list
but i want a generic unbranded cda so i can update with seus or ota via update from phone

can someone recommend a good generic unbranded cda for USA that will go good with the fw and fs listed above

and can i just change the cda with out flashing the main and fs again if so how thanks

With yours main and FS use this custpack Top Sony Forums and for customization use this tutorial XS++ 3.1 Guide-Flashing, Customizing, Recovering - Top Sony Forums Part 4
