We would like to remind our readers that this new CM13 series firmware developed by DeVorteX is an experimental test build, so there might be some bugs in it. Galaxy S5 owners advised to exercise some caution before going forward with the custom ROM installation.

Prerequisites (things to remember before installing Custom ROM)

  • This new CyanogenMod [unofficial] CM13 Android 6.0 Marshmallow custom ROM has to be installed on the Samsung Galaxy S5-klte models only; if tried on other devices, it might get bricked [To check your device model: Go to Settings >> About phone >> model number]
  • 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 all the data by installing Clockwork Mod (CWM) Recovery/ TWRP in the smartphone.
  • Make sure USB driver has been installed in the PC or else your smartphone (Samsung Galaxy S5) 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 mid-way.
  • Though installing custom ROM improves the device's performance and UI experiences, it makes the company warranty void and they will no longer be liable to provide updates in future [users can restore warranty by flashing the device with stock-ROM].
