Android 5.1.1 Lollipop For Samsung Galaxy S4 Mini GT-I9190: How To Install It Using CM12.1 Nightly Custom ROM

Users of the Samsung Galaxy S4 Mini with the model number GT-I9190 can have the latest Lollipop experience on their smartphones with the help of a new custom ROM. The new CyanogenMod 12.1 (CM12.1) Nightly custom ROM is based on stock Android user interface with additional features and options.

The new CM12.1 Nightly custom ROM is not an official release by Samsung, so users will need to root their device before flashing the firmware. The handset is also required to have custom recovery, such as ClockworkMod, to flash the ROM.

• USB drivers for the Galaxy S4 Mini must be installed on the computer
