Hello, everyone! Did any of you here gents and ladies, root their Z1, and if the answer is yes, by which method, and secondly, is it safe? I'd like to root my phone just to be able to increase my headphones' volume in Walkman app (or if anyone's got a better way to do that, please let me know). I have to mention that my Z1 is on 4.3 now, build 14.2.A0.290. Thank you all!
