For those of you who want to root your Galaxy Note 4 and also install CWM or TWRP recovery at the same time (so you can backup, restore, and install ROMs), you can use the CWM/TWRP root method for rooting.
This root method works on all KitKat and Lollipop including Android 4.4.4, 5.0, 5.0.1, 5.0.2.
For Android 5.1.1, please see new Android 5.1.1 root method here.
This root method will work on all Note 4 models except AT&T SM-N910A and Verizon SM-N910V, both of which have locked bootloaders (you will have to wait for Safestrap Recovery instead).
This root method will work on most Galaxy Note 4 models including:
- SM-N910F – International
- SM-N910T – T-Mobile U.S.
- SM-N910P – Sprint
- SM-N910R4 – US Cellular
- SM-N910W8 – Canadian
