Cannot Upgrade jailbroken iPod touch 4.3.3 to iOS 6.1.2 I got a jailbroken iPod from a friend and I want to update to iOS 6 so I can restore my backed up data on it.

I tried SHIFT + Restore / Upgrade to iOS 6 but the first error I got was this

Then I did some research and ended up getting TinyUmbrella and doing the hosts redirection and SHSH trick. After that I repeated the restore process now I'm getting this error (Figure 2) in the second phase of Verifying Update iPod update with Apple (Figure 3)

PS: I also tried DFU mode but I got error 1600.

Can you please help me restore or update my iPod to any OFW. My goal is to remove the CFW.
I finally resolved this. It turns out I had 6.0 (I didn't know because my friend was the one who got it and Apple isn't signing it anymore). I downloaded 6.1.2 and then my IP got blocked for too many requests. So I used a VPN for verification and then it worked.

So, like @Chris A said; You don't need to do all that TinyUmbrella crap (unless you're downgrading). If you have the current iOS offline (like in my case) or updating to the recent firmware, it'll work just fine.

Thanks to all that stared at my question.
