iPhone does not boot and keeps vibrating after replacing power button
i just replaced the power button of my iphone 5. after i put everything back together i noticed that the power button still did not work, so i connected the charger to it, so it would start automitically. but it didnt. the screen remains black and it vibrates every 5 sec for two times. when i connect it to itunes, itunes ask for a simcard and a pin.
where is the mistake? (note: i had to cut the battery from the iphone while it was still running, because i could not shut it down with a broken power button)
