Prerequisites (things to remember before installing Custom ROM)

  • This new CyanogenMod Android 6.0 Marshmallow CM13 custom ROM has to be installed on Samsung Galaxy S4 GT-I9505 (jfltexx) international LTE models only, if tried on other devices, they 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 future [users can restore warranty by flashing the device with stock-ROM].
  • Make sure the device is rooted before going ahead with custom ROM installation.
  • Installation of custom ROM requires clearing memory in the phone, so make sure to back all the data by installing Clockwork Mod (CWM) Recovery/ TWRP in the smartphone.
  • Make sure USB driver is installed on the PC or else your device (Galaxy S4 LTE) will not be recognised by the computer.
  • Make sure your device has more than 80% battery, or else there is a chance of the smartphone getting temporarily bricked if the installation process is interrupted midway.

If the step-by-step installation process is not followed properly, there are chances of the smartphone getting bricked or being permanently irreparable. IBTimes India cannot be held responsible for any damage or claims from readers if the procedure does not yield the required results or if the smartphone is bricked.
