Galaxy Grand Duos users can now upgrade their devices to the latest Android software version, 4.4.1 KitKat, using unofficial CyanogenMod (CM) 11.0 build, released by recognised XDA developer, pawitp.
One of the key features of the CM 11 is that it can be used on both GT-I9082 and GT-I9082L variants of Galaxy Grand Duos. Most of the features are working in this update. The developer has also noted that as this custom build does not work on Android 4.1 stock ROM's, users need to upgrade the device to Android 4.2 before flashing.
