Hi. I am wondering what exact files I need to debrand my se w200. This is what I have so far. W200_R4HA014_FS_AMERICA_1_RED52.rar, W200_R4HA014_MAIN_GENERIC_ME_RED52.rar, w200_Melinda_Generic_CDA102737_4_R1A_GENERIC_MEDIT ERR.zip.

My phone is through rogers. I did the upgrade through the sony update service and that put my phone to 53. Please let me know if i have to change some of these files. Thanks.
