I recently updated my iPhone 4S and now it stuck on the apple sign even though it makes the sounds of starting up it doesn't work I connected it once to a DJ bord. Can anybody help how to completely restart the Phone.
To restart the phone, you should press both the home button and the power button at the same time. wait until the apple logo goes and then comes back up on the screen before you release. If that does work, try going to dfu mode before restoring using itunes.
