Reflash help!

Hi! i'm new to flashing and i just flashed my k530i to a w660i but I cant use flash themes... maybee something got wrong... maybee i used the wrong files...
so... ...heres my questions:

- can i directly reflash it to a w660 or do i have to flash it back to k530i first and then flash it to a w660 again?

-Which files should i use to make it support flash themes?

Thx/Jonteex :)

yes u can directly reflash it to a w660 as for the flash themes iam not sure as iam not a modder:(
