i flashed my w580i with the following files. everything seems to be working fine but it doesn't have the language i wanted. is there a limit tohow many time the phone can be flashed?

580_R8BA024_MAIN_GENERIC_LA_RED52.mbn
W580_R8BA024_FS_C_ASIA_RED52.fbn
W580_CDA102568_7_R8A_GENERIC_C_ASIA

i would like the phone to display thai characters. what files do i need and what does each of the three files do?

thanks.
