Having problems with suddenly reboots after 3.1 upgrade. My phone worked perfectly on 3.0.1.
Have upgraded to 3.1.2, but the phone still reboot. I wanna go back to 3.0.1 but this is not possible on 3GS!?

Have found the Phones panic logs on my mac. They report the following:

Yesterday, it rebooted 11 times!!! Most of the times when using iPod. But also using Spotify. It even rebooted in my pocket running no apps.

It have also rebooted in the middle of a phonecall. Of course an important call....

Please Apple, let me downgrade to 3.0.1!!!!

    Put the phone in DFU mode.

    * Plug the phone into the computer with iTunes running.
    * Press the power button (aka sleep/wake button, the one in the upper right corner) and then right away press the home button while still holding the power button. Hold both buttons down for 10 seconds.
    * After the 10 seconds, release the power button but keep holding the home button.


    If it works, then you should see a pop-up indicating that iTunes has detected a phone in recovery mode (in Windows, there's also a sound effect from the OS typically to tell you a device has been recognized). You can let go of the home button when you see this. If you don't get this indication, then try again.

    Once you get the popup, then click the okay button and then restore the iPhone from your backup.

    If you've done DFU mode, then yes.

    This also occurs if you've "jailbroken" your phone. Please tell me you havn't done that?

    Well, if you've restored as new...
    Long shot, but try this, find the .ipsw file on you computer, delete it. Re-download & try a restore again. You've got nothing to lose, and there is a chance the original file got corrupted. Again, it's a long shot, but you never know...

    For most people, it takes a couple of trys to get into DFU mode. Watch the video in the link I provided.

    In DFU mode, the iPhone screen backlight is not even on and the display is blank. If you have anything on your display you are not in DFU mode.

    Try updating the iPhone to iPhone OS 3.1.2 again, as described here: http://support.apple.com/kb/HT1414

    If you are using any accessories with the iPhone, try testing without them.

    You can also try setting the iPhone up as a new phone. This article: http://support.apple.com/kb/HT3828 provides more details about setting your iPhone up as a new device.

    Try contacting the cellular service provider if the issues persist. This article: http://support.apple.com/kb/HT1937 provides contact information and links for many cellular service providers.

    A L1 dcache parity error is a hardware fault on your cpu, it's likely you have a bad SRAM. 3.1 probably exercises the CPU and/or the cache in a slightly different enough way that it exhibits this problem more often for you. I'd take it up with a Genius or Applecare....
