This article describes the steps required for firmware upgrade in Netgear R8000. Here I use OEM firmware downloaded from the NETGEAR support site and DD-WRT firmware downloaded from here.
Step1:
Log in to the router web interface i.e. 192.168.1.1 and navigate to the Advanced -> Administration ->Backup Settings as shown in figure 1.

Step2:
Click the “Erase” button under “Revert to factory default settings” section as shown in figure 2.

Step 3:
Click the “Yes” button as shown in figure 3.

Step 7:
It is always recommended to reset the router to factory defaults after successful firmware upgrade. This can be done by pressing the reset button for say 30secs as shown in figure 9. You will need to use something pointed to press the reset button, I use a pen for the same.

Step 8:
After reset, you will be logged on to the DD-WRT web page and asked to enter a new username and password as shown in figure 10.

Step 9:
Enter the username and password for the same. (Default username = root and password = admin for DD-WRT) and then click on the “Change Password” button as shown in figure 11. It is recommended to clear the cache of your web browser before using it.

Step 10:
Then you can see the status page of your router and the firmware version as shown in figure 12.
