How to Install TWRP on Android
This method is universal and works for most Android devices.
Go to the Google Play Store, then download and install the Official TWRP app. Open the app and accept the terms and conditions. Select the Run with root permissions check box, then select OK. If you got this far but don’t have root access, flash TWRP on a device with an unlocked bootloader using Fastboot. Select TWRP Flash, then select Allow for any access requests that appear. Select Select Device, then choose your device from the list. Either type the name of the device or scroll to search for it. If you don’t see the exact model of the device, you can’t go any further or use most of the app’s features. Download the latest TWRP image file for the device and save the file in the internal storage. Return to the app and select Select a file to flash. Find and select the image file. Select Flash to Recovery, then confirm the action. The operation completes in seconds.
Confirm That TWRP Installed Correctly
To see if the setup process worked, when the option to restart your device appears, select Recovery mode. The device restarts and goes to the TWRP interface instead of the Android home screen.
