A new Android 5.1.1 Lollipop update,  SlimLP custom ROM has been made available to Samsung's 2013 flagship compact smartphone, the Galaxy S4 Mini.

It is 200MB in size and brings new value-added features to enhance user experience. 

Prerequisites (things to remember before installing the Custom ROM):

  • This new SlimLP Android 5.1.1 Lollipop custom ROM has to be installed on Galaxy S4 Mini LTE (GT-I9195) only, if tried on other devices, it might get bricked [to check your device model, go to Settings >> About phone >> model number].
  • Though installing custom ROM improves the device's performance and UI experiences, it makes the company warranty void; the company will no longer be liable to provide updates in the future [users can restore warranty by flashing the device with stock-ROM].
  • Make sure the device is rooted before going forward for custom ROM installation.
  • Installation of custom ROM requires clearing of memory in the smartphone, so make sure to back up all the data by installing TWRP/Recovery app in the smartphone.
  • Make sure you have installed USB drivers on the PC, or else your smartphone (Galaxy S4 Mini LTE) will not be recognised by the computer.
  • Make sure your device has more than 80% battery, or else there is a chance of smartphone getting temporarily bricked if the installation process is interrupted midway.
