Those who are interested in tinkering with the Android operating system, in general, need no introduction to TWRP Recovery since it is the most popular custom recovery image in the world. A custom recovery is of course what we need to be able to flash new custom ROMs that arrive by third-party developers and do things like take NANDroid Backups, which is the only way to make a convenient full backup without ADB commands and a computer. Furthermore, there are many occasions when a custom recovery image is necessary to root a device, such is the way with the OnePlus 3 smartphone.
- You need to unlock the bootloader on the OnePlus 3 smartphone before you can follow this guide to install a custom recovery on the device. Attempting to follow this guide with a locked bootloader will not only be unsuccessful, but it will also brick the device.
- You must have the OnePlus 3 smartphone to flash the custom recovery image that is found in this guide. A custom recovery image is usually specifically tailored for a device and as such as you cannot go around flashing them on just any old device. They are made for one device only.
- You must have a computer that is running the Windows operating system to use this guide. Those of you without a Windows PC will be unable to install our ADB and Fastboot since our guide is about the Windows version only since it is by far the most popular. Nevertheless, ADB and Fastboot are available for other operating systems like MacOS and Linux distributions; you just need to find them. Moreover, you will need to run a separate set of commands because MacOS and Linux operating systems do not accept the same commands as Windows.
