    I recently updated the firmware on my Ipod Touch 3g. After this happened, the Wi-Fi and bluetooth were greyed out, an error I found was common among iPod owners. I tried everything I could find - putting it in the freezer, resetting network settings, resetting the whole ipod, etc. The only thing I can think of now that will work is downgrading the firmware on the Ipod.

    However, downgrading the firmware seems to require that you be in DFU mode. Apparently, Apple stopped offering the ability to get into DFU mode with the latest versions of OS X. Since I have a Mac with Snow Leopard, I can't get into DFU mode. Does anyone know of a way that I can downgrade my Ipod firmware with a Macbook with Snow Leopard?

    Alternatively, does anyone know any sure-fire fixes for this common problem? It's already been such a headache - I've spent so many hours in vain trying to fix this problem.

    Putting it into a freezer? Lol, never heard that one.

    Unfortunately you can't downgrade the OS unless you saved your SHSH blobs from an older OS. Apple stopped signing the older versions. Have you tried restoring your iPod and setting up as new or even resetting your wireless router?

    Normally if the wifi and bluetooth are greyed out it means your broadcom chip (inside the iPod) actually died and software resets won't make it work.

    He'd be seeing an airplane, not the WiFi or Bluetooth icons, lol.

    Right now, I am just looking for help in downgrading the firmware. It doesn't look like a hardware issue, since this just happened when I updated the firmware. I know this was a common problem, but it seems about impossible to downgrade the firmware.

    I've tried clearing and resetting the ipod. So there is absolutely no way to downgrade the ipod firmware? Has apple done something about this problem since it's so common?

    It won't have anything to do with my router. The wi-fi is greyed out and says "no wifi"; the Bluetooth is greyed out and says "unavailable." Oh, the woes of having an ipod that stops working after an apple software update. ****in piece of ****

    My iPod Touch did the same thing when I accidentally set it up from a backup of my iPhone.

    I'd say bring it into Apple if it just started happening recently, but you may not have warranty left if it's an iPod touch 3g. I just looked up the issue and lots of people were having the same issue on iPhone OS 3.0 and people were saying it could be hardware.

    If your warranty is out, it's possible they could still help you.

    Were you able to resolve your issue?

    I have heard of the freezer option. You put it in freezer than blow hot air to activate semiconductors of the chip. The process is know is reflow, i guess?

    So my questions is... how did you put in freezer and for how long? I mean in a plastic bag or something? Because the moisture can mess with other chips which are working good.

    Let me know because i have the same problem with my iPhone 4. Moreover, it does not turn on without a wall charger.

    You might be able to downgrade to 4.1 - it's still being signed for the 3GS and iPod touch 2g... perhaps its being signed for the iPod touch 3G as well.

    With that said, I'm positive your issue is a hardware issue. Timing is a pure coincidence. If it is a software issue, even a normal restore to your current firwmare would do the trick. Think about it - if Apple released an update that killed wifi and bluetooth, they would've released a patch very quickly (or at least pulled the update and reopened the signing window for the previous version). Since they did not do that, it is reasonable to assume that wifi and BT work fine on other iPod touch 3Gs with the same firmware.
