Prerequisites (things to remember before installing Custom ROM)

  • This new CyanogenMod CM13 Android 6.0 Marshmallow custom ROM series has to be installed on Motorola-Google Nexus 6 (aka Shamu) model 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 in the PC or else your device (Google Nexus 6) will not be recognised by the computer.
  • Make sure your device has more than 80% battery, or else there is a chance of the device getting temporarily bricked if the installation process is interrupted midway.

[Disclaimer: This procedure is very technical and should be performed by a person with sound knowledge of rooting (or manual software installation) Android devices. 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. Hence, users are advised to proceed with caution.]
