    Which step(s) do you have problems with?
    The more information you can give us, the better we can help you.

    The guide should work, so I recommend going through it step by step, and if you receive an error or get confused, write down what you see, what was the last thing you did, stuff like that.

    good luck!

    Just remember to back up your device before you upgrade.

    You can skip the step of wiping the device if you don't wanna do it.You can update directly from OS 4.6 to OS 5 but don't forget to delete the vendor file.Just follow the steps in the guide except the step of wiping.

It commanded click next to update the following application but there was no nex button.there is my problem.

    I suggest using the Loader as shown in the guide.
