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.

Here are some points to remember before installing the custom ROM on the Galaxy S4 Mini:

  • Users must ensure proper backup of personal data on the phone
  • The handset should have at least 80 percent battery power
  • USB drivers for the Galaxy S4 Mini must be installed on the computer
  • USB debugging must be enabled on the phone
  • Make sure that the device is a Samsung Galaxy S4 Mini with the model number GT-I9190

Step 3: Connect the Galaxy S4 Mini to the computer, and transfer the CM12.1 ROM file and Gapps package file to the device’s SD Card. It should be noted that the files are saved in the SD Card root, and not in any other folder.
