Iphone went dead and I have it plugged into the computer now and the Apple logo comes up for a second and then goes away.  Keeps on flashing.  Computer doesn't recognize phone either.  New battery and phone dock.  Worked fine for about a week and a half and now it is flashing the logo and won't come on.  Tried the soft reset a couple of times and still no luck.  Any ideas?

iPhone 4, iOS 6.0.1

    HI there,

     

    I would recommend taking a look  at the troubleshooting steps found in the article below.

     

    iPhone: Hardware troubleshooting

    http://support.apple.com/kb/TS2802

     

    Will not turn on, will not turn on unless connected to power, or unexpected power off

    1. Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
    2. Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
    3. Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
    4. After at least 15 minutes, if:
      • The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen HT1650_2.jpg. Then unplug the phone from power. If it immediately turns off, seek service.
      • The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
      • Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
    5. If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
      • If the display turns on, go to step 4.
      • If the display remains black, go to next step.
    6. Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
    7. If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.

    Issue not resolved

    My issue is still not resolved. What do I do next?

    Contact Apple Support.

    This happened to my wife's phone which has never been backed up. I didn't want to restore it because it would erase everything on the phone. So, I thought about what caused this issue in the first place, which was that it got nkocked while in her jacket pocket.

    So, I plugged it in to the power source (not the computer), then dropped it a couple of times from about a foot high. Bam, it turns on. I quickly unplug it and plug it in my computer to back it up to iTunes. Initially the screen went black when I unplugged it from the power source then into the mac. After about 20 seconds it buzzed then I was prompted to back it up.

     

    I know, random but it worked and now my wife's POS iphone works again and is backed up.
