As per the instructions, I have managed to do the process up to downloading Android SDK file to my computer. However, when I was asked to open the Tools folder inside of the zipped archive and open the Android SDK Manager executable, it only contains some updates and not the Android SDK Manager. Please explain why is that.
I have already installed Oracle Java 7 to my Computer as per instructions I cannot proceed after that. Please explain me to Root my Phone to get an update new version of Android. Thanks!
