iphone 5 keeps restarting after update of 7.1.2

Hi,

I got the same problem after upgrading mine to 7.1.2. I went to Genius bar today and the staff have tried to restore (DFC) the ISO again, but it turned out the same. They have no idea what was actually going wrong. Hopefully, Apple will have a fix for this problem soon.

Turn your device off and connect your cable to the computer, but not the device just yet. Start up iTunes. Now, hold down the home button on your device and plug it in to the cable - don't let go of the button until iTunes tells you it's detected a device in recovery mode. Now you can restore to factory settings.

My iPhone 5 started the restarting problem after I updated (OTA) from ios6 to ios7.1.1. The restarts became so frequent that the phone became impossible to use. I then bought a cheap android phone as I believed apple were going to release an update to solve the issue. Imagine my disappointment today after upgrading to ios 7.1.2, and immediately after the upgrade, the phone goes back to the restarting loop!! 😟 😟 I doubt that restoring the phone will do any good, I restored mine many times after my previous upgrade.......& still the problem persisted.I am not prepared to go through that pain again. I think I will just save-up & get myself the Galaxy s5 (never thought I would live to see the day that I would say this 😟). I am deeply disappointed by apple 😟 😟.

Guys, any one went to a solution for this annoying problem, just had the same issue two days ago and even recovery option didn't make it.
