    – both custom Recovery types are supported by this guide.
  • make sure that you have the USB Debugging enabled in Developer Options.
    – this isn’t mandatory but in case you download the files on your PC, then you will be forced to move them to your device for the installation process.
  • in the ‘how-to’ part of this post you will find two extra prep steps: the NANDROID Backup for the already installed ROM and the Factory Reset.
    – make sure not to skip these steps.

  • sync Contacts data with your default Gmail account.
    – if you don’t know how to do it, then you can use our tutorial here.
