Hey guys… My iphone 5s has gone into a Logo loop after installing iOS 9.3.4 It goes on, turns itself off and i have tried getting it into DFU or Recovery mode, but as soon as i unplug it from a wall charger it goes black and does nothing. It shows me the itunes logo with the lightning connector on the screen but i cant unplug the phone or it will turn off. Also i can only plug it into a wallcharger, because if i try the same on a pc, it doesnt turn on. Weird right. Shame for apple to give no support to me at all. I just bought this phone because my older 5c did this just a week ago and now this one too.

try this: with itunes open, plug the usb end of a lightning cable into the computer. Then, while down the home button on the phone, plug it into the cable
