+# Rooting a OnePlus 6T
+
+The easiest way to root a OnePlus 6T handset is to flash it with LineageOS. Recent versions of LineageOS allow you to enable/disable 'root' directly from the system's settings menu, making it ideal for reverse engineering applications which have root detection.
+
+At the time of writing, the latest version of LineageOS is v18.1 (Android 11), and can be downloaded from [here](https://download.lineageos.org/fajita). The official LineageOS installation instructions can be found on its [wiki](https://wiki.lineageos.org/devices/fajita/install).
+
+N.B. Some applications (annoyingly) require the Google apps suite in order to run. These can be downloaded from [here](https://wiki.lineageos.org/gapps.html).
+
+## Requirements
+
+1. Android Platform Tools.
+2. An OEM unlocked bootloader.
+3. LineageOS recovery image.
+4. Partition copy utility.
+5. LineageOS system image.
+6. Google apps suite.
+
