  • Make sure the device is rooted before going forward for custom ROM installation.
  • This new CyanogenMod CM13 Android 6.0.1 Marshmallow custom ROM has to be installed on the Samsung Galaxy S5 (GSM) LTE with Snapdragon CPU - model only; if tried on other devices, it might brick them [To check your device model: Go to Settings >> About phone >> model number]
  • Installation of custom ROM requires clearing of memory in the smartphone, so make sure to back all the data by installing Clockwork Mod (CWM) Recovery/ TWRP in the smartphone.
  • Users make sure they have installed USB drivers on the PC, or else your smartphone (Samsung Galaxy S5) smartphone will not be recognized by the computer.
  • Make sure your device has more than 80 percent battery, or else there is chance of smartphone getting temporarily bricked if the installation process is interrupted mid-way.
