You're Welcome 🙂 Enjoy

I have the same problem - however, this only happened after I upgraded from iOS 5.1.1 -> 7.0.4

Now I cant shutdown the iphone and the sound also doesn't function anymore ... well it does at random sometimes

I havent figured out what exactly it happens when the sound starts working again.

The phone worked 100% before the software upgrade and now its a brik with no sound and cant be shutdown.

I've tried the usual, reset, restore and DFU mode and start fresh.

Also deleted all the downloaded packages from the computer, so that itunes downloaded a new fresh package, just in case something got corrupt during download.

I've done this 3 or 4 times now, with no change at all.
This is a software bug in the latest iOS ... somewhere between 5.1.1 and 7.0.4 something got broken. Id would like to downgrade, but it seems that its not possible.

Downgrading the iOS is not an option. That is why I have learned to be reluctant to upgrade. I still have not ugraded from iOS 6 and I am still not convinced I need to.

A curious thing happened today. I happened to mention in casual conversation with a guy that my phone would not power down. He suggested I try putting it in airplane mode first before powering down. Lo & behold, it worked. My phone is now sitting on the desk in front of me powered down without the USB cable plugged in. I have no idea why this may have worked or if it will work for everyone with the problem but I thought I should mention it here so people can try it on theirs.

I have the same problem, again an iPhone 4S 64GB running latest iOS 7.1.1.. To me this sounds like a design flaw and should be recalled by Apple... Went to the 5th Ave Manhattan Apple store and was told it is a $200+ repair, for a logic board??? Give me a break! If Apple does not take responsibility of this issue I am done with Apple - not paying a premium for poor quality and bad service.

Are u serious ? It's so expensive, my problem is done, just spend $20 to repaired in indonesia

Dear Guys,

Do you still have this problem?

I have bothered with the very same problem with my iPhone 4 for a few weeks.

And I succeeded to fix it.

What I did is...

- I opened the back panel of the iPhone. (a special screw driver is needed)

- Disconnected a connector of the dock connector.

(means contact between the dock-connector-unit's flexible cable and iPhone's main board)

- Clean around the connector with air blow.

- Re-Connect it just as before.

- Close the back panel

That' All

I tried that because I read an article saying that one reason of the rebooting loop problem is improper electric contact inside or around the dock connector.

This improper conduction makes an iPhone misunderstand as if he is commanded to turn on the power always.

This conduction might be caused by dirt in a case, or broken pins or cables in other case.

If the problem happens with just dirt, there can be the chance to fix it by cleaning.

If it's because of broken parts unfortunately, we have to replace the parts.

In my case, simple cleaning and re-connection did work.

Please be careful, when you open the back panel by yourself, you lose warranty.

I did it because my iPhone is enough old and already out of warranty.

Please check the way to open the iPhone with youtube or some web articles if you want to do this.

Good Luck!
