XS++ sayz if u want to convert to CID52...if XS++ convert it from CID49 to CID52...after that i flash the Erom with on of these files...

W610_RED_CID52_R3B021_EROM-FOTA_2006-12-18_15
W610_RED_CID52_R3B025_EROM-FOTA_2007-06-14_07
W610_RED_CID52_R3B025_EROM-FOTA_2007-07-24_14

then flash with any firmware....what u say...will it work?? btw thanks again...
Or is there any other method of accessing the filesystem on this fone???
