how to restore iphone 5s without itunes?
My iphone 5s keeps getting a blue screen and keeps looping on and off. It will restart and go blue, then after a minute it will reset again and go blue and just keep doing this. Sometimes the blue screen will turn to vertical stripes and they'll fade and the iphone will just be off again. Recently, my iphone won't even turn on though, or the apple sign will appear on screen and it will hang there for a couple minutes and then just go black again.
I tried plugging it into my computer and itunes will come up and let me attempt a recovery mode, however, every time the download for software fails and I can't do it. Occassionally, my iphone will successfully turn on and when it does, I try to perform a reset with itunes but itunes won't detect my iphone at all!
Is there any other way I can try to reset my iphone?
Thanks
