Q: I would like to downgrade the ios

You can't

Apple has never approved a method to downgrade iOS

I'm sorry, but Apple does not provide a downgrade path for iOS. Because downgrading is unsupported by Apple we cannot discuss it on these forums, but you can use Google to find information on how to install an older version of iOS on any iDevice.

I wasn't finished

You still can't

i've heard you can put your ipod into DFU mode by holding the power button for 3 seconds then keep holding the power button but press the home button and hold it for another 10 seconds then let go of power button and hold the home button for 15 seconds. itunes will pop up saying it has discoverd an ipad 2 on recovery mode and must be restored right click restore and pick your ios version that you need to download ( i will put link) and then hit restore and it should work.
