Step 6. Switch off your Nexus device and boot in fastboot mode. Nexus 7, users will need to switch off the device and then press the Volume down + Power button. Nexus 5, switch off the device, and then simultaneously press the Volume up + Volume down + Power button. This should get you into Bootloader mode.
Step 7. Connect your device to the PC with USB cable.
Step 8. Open the ADB folder on the desktop and hold SHIFT key on your keyboard and RIGHT CLICK and select “Open command window here”.
Step 9. In the command prompt window, enter the following command:
fastboot flash recovery recovery.img
Step 10. Now this will install the recovery on your device, use the Volume buttons to select the “Restart bootloader” option and press the Power button.
That’s it, Now the recovery is installed and next step is to root the device.
Step 12. Now copy the downloaded SuperSU and Boot files to a safe location on your device.
Step 13. Switch off your device and boot in recovery mode. Press the Volume Down + Power button together until the device shows START written with an arrow around it. Press Volume Down two times until it shows recovery option, Now press the Volume Up key to enter recovery mode.
Step 14. Select Install zip » Choose zip from sdcard » browse to the location where you saved the file and select the SuperSU file. Flash it first and after that flash the Boot file with the same way.
Step 15. Now reboot your device. Go back to the main menu of recovery and select reboot system now.
Your phone will now restart and the first boot may take some time to complete. So, wait until the device boots to the homescreen.
