Step 3: In Recovery menu, use volume keys to select “apply update from ADB” and use the power button to make the selection.
Step 4: With your device connected to your PC using USB cable, fire up a command prompt window and enter the following:
adb sideload OTA_Package_Name.zip (where OTA_Package_Name has to be replaced with the actual filename)
