Ipod Touch Help
Have you tried a reset?
From here.
To reset the iPhone or iPod Touch, press and hold down the Sleep/Wake button and the Home button simultaneously at the same time for at least ten seconds, then the LCD display will clear and the Apple logo appears on the black background. When Apple logo appears, reset is done.
I recommend what the moderator said but this is another option for downgrade, Try this:
READ FIRST. Plug your ipod back in, if you can do it in that same state, this time when u go to restore it, hold down ALT key and click RESTORE, then search for the 1.1.4 firmware in your computer that you downloaded. I'm not a 100 % this will work but it's something.
If during any process of restoring, your ipod's screen turns black and u can't restore it to the normal screen or just can't change it, don't worry this happens to many people (it happened to me), just simply hold the reset button and the home key for a really long time (were talking minutes), if its been over 3 minutes do it again. Do it until it's back to normal. Good luck mate!
I tried to hold the reset button for mins but it just keeps on tuning on and off showing the same screen and when i connect it to itunes the computer nor the ipod reacts so i cant restore it is there a program or something to restore my ipod without itunes
Try holding both the home and the reset button for a while. Or try pushing these buttons numerously
ill take it to repare ive tried everything i cant get it to work
You can reset your ipod and downgrade those option which occurred on your ipod.
