  • This Android v4.4.4 KitKat Dirty Unicorns custom ROM has to be installed only on Samsung Galaxy S2 GT-I9100 [To check your model: Go to Settings >> About phone >> model number]
  • Make sure the device is rooted before installing the custom ROM.
  • Installation of custom ROM requires clearing of the memory in the device, so make sure to back all the data by installing Clockwork Mod (CWM) Recovery/ TWRP.
  • Users make sure you have installed USB drivers on the PC, or else your device (Samsung Galaxy S2 GT-I9100) will not be recognized by the computer.
  • Make sure your device has more than 80 percent battery, or else there is chance of the device getting temporarily bricked if the installation process is interrupted in the mid-way.

[Disclaimer: This procedure is very technical and should be performed by a person with sound knowledge of rooting (or manual software installation) of Android devices.
