Hello Xperia followers, first I must say, that I am not very familiar with android. Since years I was using a symbian mobile. In January I changed to a Z3 and I was astonished, that several apps couldn't be installed. Beside that, I don't have access to the externel SD-card. Now I heard, that rooting the mobile will help. But it normally can be rooted only when the bootloader is unlocked/open (?). There shell exist a 2. chance to root, but only with a special firmware. I also read, that there will be a possibility to lock the bootloader again after beeing unlocked. Having an unlocked mobile shall be a disadvantage with the photo app and ..... Is this disadvantage reversed if this "re-lock" is done? I have many questions and a mobile, which doesn't work in the way it should. Is there anyone who can answer? Erich
