w810i...I'm confused,need help

[Khaba]

according to your CID use these files:
MAIN: W810_R4EA031_MAIN_GENERIC
FS: W810_R4ED001_FS_EUROPE_5
Custom pack: Helen_CDA102494_44_R1A_Generic_Trade_Italy
or: W810_CDA102555_14_R2A_Generic_EUROPE_5

For CID 49 use main and fs CID 49, for CID 50 use CID 50 versions.

U can find out what CID to use by connecting to XS++ or SeTool lite and Identify and look at OTP CID and EROM CID.
