20120709 was running fine, but i wanted a feature that was introduced in cm-9-20120709-EXPERIMENTAL-galaxys2-VOLUMEDROPFIX-LUXRANGE.zip. In fact, this feature was available since the Gingerbread days of the Galaxy S2 (stock ROM).

1. Create backup using ROM Manager.
2. Download cm-9-20120712-NIGHTLY-galaxys2.zip via browser.
3. Verify MD5 checksum 945d28a85ed02f0ecdccdaf57cd97db4.
4. Reboot into CWM Recovery.
5. Flash cm-9-20120712-NIGHTLY-galaxys2.zip
6. Wipe cache partition.
7. Advanced > Wipe Dalvik Cache.
8. Reboot.
Verified!
