Pre-requisites

Rooting the OnePlus 3 is a fairly easy procedure, but we do recommend that you read and understand the guide properly. If you don't know it, don't do it.

Rooting

Root can be achieved by just flashing a zip file containing the SuperSU binaries with the help of a custom recovery (TWRP recommended). Also there are some custom ROMs that are pre-rooted, so flashing one will get the work done.
