iphone 5s won't turn on after ios 8.0.2 update
Hello so i updated my 16GB iphone 5s to ios 8.0.2 because i too had problems with the previous versions and after the update it had to restart my phone except now it wont turn on. After trying to restart it all it comes up with is the apple logo that comes up when you restart the phone and then after a while i will get the "blue screen of death" I have left my phone on all day to see if it will restart but still the same cycle of the apple logo and then the blue screen. I know other people have had successful updates with the 8.0.2 ios update but i haven't unfortunately. I have drained my phone battery and after that it did display that i needed to connect my phone to a charger but as soon as it got charged it still restarted with the apple logo followed by the blue screen. The blue screen also has a single line running across horizontally, the position of changes after every attempt of restarting. I have also tried turning off by the home button and the sleep button but still doesn't work and also my itunes wont read that my phone is connected whilst it is resetting.
Any ideas or solutions? Help would be much appreciated as i have a fairway to travel to go to an apple store. Thank you.
iPhone 5s, iOS 8, 8.0.2
