Q: I recently updated my iPod touch 5th gen. to ios 8.4. Now every time I turn the wifi on my iPod changes to weird colors and restarts itself. Help what do I do?

Take a look at this Apple Support article:

https://support.apple.com/en-us/HT204051

Reset your network settings.

Settings - General - Reset - Reset Network Settings

Reset your device. This won't delete your data stored on the phone.

• Press and hold the Sleep/Wake button
• Press and hold on the Home button
• Keep holding both buttons until the display turns off and back on with Apple logo on it.

Alternatively, you may go to Settings - General - Reset - Reset All Settings

Hope this helps!

If not successful:

- Restore from backup. See:                                               

Restore your device from an iCloud or iTunes backup - Apple Support

- Restore to factory settings/new iOS device.                       

If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

I have the same problem, and when I try to reset my iPod, it says I have to turn off "Find My iPod", however, since I cannot connect to wifi, it is impossible for me to change any of my iCloud settings... Any suggestions?

Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.

iOS: Forgot passcode or device disabled

If recovery mode does not work try DFU mode.

iTunes: Restoring iOS software

To restore from backup see:

Restore your device from an iCloud or iTunes backup - Apple Support

If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.

You can redownload most iTunes purchases by:                         

Downloading past purchases from the App Store, iBookstore, and iTunes Store        

If problem what happens or does not happen and when in the instructions? When you successfully get the iPod in recovery mode and connect to computer iTunes should say it found an iPod in recovery mode.

Yes I have the same problem too. I tried resetting it, restoring it, and put it in recovery mode and it still does the same thing. I have no idea what the problem is so any suggestions would be great! Thanks!

There is nothing more you can do than in my previous reply

Oh boy well I guess we are out of luck... Thanks anyways
