Twrp install instructions:

Step 1: Download the TWRP recovery and latest SuperSU zip file for your Google Pixel and Pixel XL devices. There are 2 TWRP files with .zip and .img extensions. You will need both. You don’t need to extract the files, just place all the files on your PC as well as your Android phone’s internal storage where you can easily locate it.

Step 2: Make sure that you setup ADB and Fastboot on your PC and gone through all the prerequisites from above.

Step 3: Now plug in the Pixel device to the computer and open a command prompt or terminal on your PC to the window where TWRP.zip file is located. (See above to know how to open cmd)

Step 4: Boot your Android device into the bootloader or Fastboot mode. To do so, issue the following command through cmd or terminal. You can also manually boot into it using the hard key combination like Power+Volume Down while the device is turned off. Meanwhile, use code:

adb reboot-bootloader

Step 5: Now issue the following command in the command prompt to check your device connectivity

fastboot devices

Step 6: Now issue the following command to temporarily boot up the TWRP image.

fastboot boot path/to/twrp.img

Note: If you have installed our recommend quick 15 second ADB & fastboot installer, you do not need to insert the complete file path. Simply go to where the TWRP image file is and issue command “fastboot boot twrp.img” Otherwise, note that “path/to/” is the actual directory for the TWRP image file. Use fastboot boot and not fastboot flash and that the file you are booting is not the zip file.

Simply After that, TWRP will be accessible to you no matter which active partition slots are being used.

Step 7: After that fastboot command, you will be rebooted into a temporary TWRP recovery interface. To make it permanent, use the TWRP interface to navigate to and install the TWRP.zip file. This is just like using TWRP to flash custom ROMS and SuperSU.

Once the installation completes, you can now enjoy your new firmware. Alternatively, while, on Mac OS, you can issue “./fastboot boot path/to/twrp.img” command or on Linux type “sudo fastboot path/to/twrp.img” to flash the TWRP.
