Hey dear Community,
sorry but i translate my question with translate.google.com :D
And its like this.
I bought the Alcatel Idol 4 me a few weeks ago.
Super price-performance ratio.
Now I have only the problem that I never in large Internet find a way to root my phone.
I tried already all I know Tools.
I also Kingoroot written an email with the request to find a solution.
I guess that this will take longer so again here the question.
anyone of you an opportunity that Alcatel Idol 4 (6055K) to root?
urgently need a root.
Dear greetings and thanks in advance
Your Jakami99
