  • Now, press and hold both the Volume Up and down key and then while holding them, press and release the power button. After releasing the Volume rocker key, you will get a Blue Menu along with a set of options which will indicate that the device has been successfully landed in the Recovery Mode.
  • Now, select “Apply update from internal storage” from the option and press the Power button. You will need to select the update file which you have placed in the Phone storage and press the Power button to confirm the same. It will take around 3 -5 minutes for applying the update and once it’s done, you need to select the option of “Reboot system now” for rebooting the device in the normal mode.
