osvaldo, have you tried this from here
1. Connect your iPod Touch to iTunes
2. Press or Hold the power and home keys 10 seconds.
3. Screen goes black, now release the power button
4. Make sure you do not release the Home key until your iTunes says "We have detected an iPod Touch in recovery mode."
5. Restore the iPod
and if you are using a PC, there is one more way if you do not want to lose your data First plug in the ipod, go to My Computer. Click on the ipod drive, then go to tools > folder options. Then click view, click show hidden files. Go to ipod_control. Then go to device there should be a file named "_locked" ,delete that. Unplug the ipod and you should be ready to go hope this makes sense,
Hi, there. If you entered too many times' wrong lock screen passcode on your iPod, it will prompt that iPod is disabled. Don't be nervous though. It just means that you cannot use your iPod until the passcode is unlocked. As a matter of fact, you can use recovery mode to bypass the password.
Tenorshare ReiBoot helps you enter and exit iOS recovery mode with one click. It is free and safe, neither need to connecting to iTunes to restore, nor need to damage your device. Try it if needed.
