I want to take this opportunity to appreciate and my first thanks will be to @Taifun and the second precious person whom I have followed his guides until I have managed to solve all the problems is @bodymindpower
I used this method
Then when I got some error with signing key I used this method to fix all things up
With all the help of @Taifun and @bodymindpower everything was solved
Thank you, everyone
@Lily
