Step 4 - Power off the phone and disconnect its USB cable from computer.

Step 5 - Boot the device into Recovery Mode by pressing and holding Volume Down and Power buttons on your phone until it enters the main recovery screen.

Step 7 - Then, perform Wipe Cache Partition and wait until the process completes.

Step 9 - Return to the main recovery menu and choose Install Zip from SD card.

Step 10 - Click Choose Zip from SD card. Use volume keys to navigate to the CyanogenMod ROM zip file that you copied earlier to your phone's SD card and choose it by tapping the Power button. Confirm the ROM installation on the next screen and the installation process will begin.

Note: Repeat Step 9 and Step 10 to install Google Apps (Gapps) as well.

Step 11 - Once both the Gapps and ROM are installed, choose "+++++Go Back+++++" and select Reboot System Now in the Recovery menu.

The phone will now reboot and the first boot may take about five minutes to complete. So, please be patient.
