This combination is possible, but with some problems:
SE K610/K618/V630 -> SE W660 (2.0 Walkman works erasing the camdrivers, replacing the original dispdriver by the K610 to correct colors on the screen, supports Flash Lite)
Use this files:
W660_R8BB001_MAIN_GENERIC_FY_RED52
W660_R8BB001_FS_EUROPE_5_RED52
HB1-06_Gen_CDA102568_14_R6A_GENERIC_EUROPE_5
Have a nice day
