You are advised to flash the C013 bootloader plus modem before you install the ROM or else you may end up bricking your device since this is a necessity for running the ROM.All features such as NFC, battery life, fingerprint scanning, etc, are reported to be working well in the CM13 ROM for the Note 4. Users have also been notified that IBTimes UK will not be accountable for any damages to devices during or after installation of the ROM.
