i flashed my K530i (Firmware R6BC002) to W660

I used:
W660_R8BB001_FS_APAC_RED52.fbn
W660_R8BB001_MAIN_GENERIC_FY_RED52.mbn
HB1-06_Gen_CDA102568_101_R8A_GENERIC_APAC

It works..
but theres something missing.. like the text symbols are not complete as in K530i.. i know for some people this is not important, but anybody know why?
one more..the phone act different when i connect it to myphoneexplorer, like new sms still shows up at the phone, is this because i use R8BB001 firmware?
