It is not that easy man. And I am not noob. I tried to fix it for 5 days. Do you think that I didn't try to restart my com - -. I already restart many times and it will doesn't work. Also, I tried to research many way to fix these. And none of them work - -, so do you think that I am still noob lol

sorry I try to do that strategy but my usb is not recognize so weird

what itunes version are you using, i think you have to use 7.5/7.6 for the DFU, and downgrade.
Install iTunes 7.5/7.6
Restart computer and ipod, then plug in ipod, open itunes, set DFU and try restoring to 1.1.4 or 1.1.5,
If you have restored to 1.1.4, upgrade to 1.1.5 again. or Shift click update

make sure ur cable is connect to the back of the computer

or

re download 1.1.5 agen somewhere else.

or

chuck in dfu mode but with a program like ziphone (lol) or libritiy or something.

The version that I am using is 7.7. I tried to change to 7.6 and restore but it still come out same

bumb I think there is no way to fix it

"6" is the error you get when trying to use a firmware iTunes doesn't support to restore (e.g., the hashes don't check, as in a custom pwned fw and 1.1.4). You aren't really in DFU mode if you're getting this. Here's a YouTube video that'll show you how to get into DFU mode. FTR, all of the methods in this thread only get you into recovery mode. If your iPod Touch/iPhone actually turns off via the red slider bar, you aren't doing it properly. The screen has to shut off, with no shutdown process. The video helps a lot.

to go into dfu mode have your iPod plugged in to your computer. Then hold down the him and power button until iTunes doesn't recognize it then let go of the home button and wait till a Waiting for iPod message pops up then iTunes will recognize it and you'll be able to restore

Often, though, that'll get you into plain old recovery mode unless you time it just right.

When I was jbing 2.0 this error happened, A LOT.... Then I tried one last time, and it worked... weird eh?

Keep trying and let us know. Also, there is a guide on this site for error 6.

Install Itunes 7.5 then put it into DFU mode manually.....it will work !
Remember ITUNES 7.5 !!!
