Can you help me fix the problem with my iPhone going into a spastic loop while doing an IOS update?

[iMore Question]

My 4S was fine before I started the update (believe it was the 8.1.1 but not sure anymore), five minutes after starting the update, I went to check on it and it was looping between the Apple logo, a horizontal line, a white screen then back to black and the logo. I have tried the resets, connecting to iTunes and every other thing I could find on the internet. I have finely been able to shut it off, after disconnecting from power source and holding down the home button and sleep button for several seconds. As soon as I turn it back on or plug it in, the loop begins again. I really need my phone back in working order. Any suggestions?

Put it into DFU mode and try to restore again...

I can not get iTunes or my computer to acknowledge the iPhone exists. I am using the original cable that came with the iPhone. So I am unable to get it into DFU mode. Any other suggestions?

Looks like I am heading to the Apple Store today! ;-(
If I am able to get a reset going, should I have the simm card in or out of the device?

In the device. That's essential to activate the phone
