CSC: Use CSC for a clean install, to change the region (CSC code), to downgrade or to repair a device that does not boot.
HOME_CSC: Use HOME_CSC to update the same model and region while keeping your data. Back up anyway: a failed update can still require a reset.

Frequently Asked Questions

I9100XWMS1 is Android 4.1.2 (Jelly Bean) firmware for Samsung Galaxy S Ⅱ, released for 4 countries, 4 CSC codes. Samsung built it on 2013-09-25.

No. A newer build for GT-I9100 is available: I9100ZSMSA. Install it instead of I9100XWMS1 unless you need this exact version. The previous build was I9100XWLSZ.

Download the package for your region (CSC) and unzip it. In Odin, load each file into the slot with the same name: BL, AP, CP (if the package has one) and CSC, or HOME_CSC to keep your data. Odin checks the built-in checksum of every .tar.md5 file before flashing. The Samsung Galaxy S Ⅱ must be on bootloader binary X (33) or lower.

This build uses bootloader binary X (33). It can be flashed on a Samsung Galaxy S Ⅱ running binary X (33) or lower; if the device already has a higher binary, Odin stops with "SW REV CHECK FAIL". 21 other builds of this model use the same binary, so you can switch between them in both directions.
