Different people give different fixes for these errors.
I haven't yet been able to find anywhere near the exact meaning of the errors.
They simply don't seem to be posted anywhere.

I am, and will continue to try the various fixes.
None have worked so far.

I'm sure that I'll get this iphone working again somehow, thanks to the free tools and these kind assistance on these forums.

But I still think that any user is in a more informed, maybe even more powerful position when given the actual meanings of the error messages rather than having to guess at them.

The problem is that the same error can mean so many things - that's why there are so many fixes.

It once took me six hours to get my iPhone fixed from 160x errors - keep trying.

I think we are looking at a problem that comes from the iphone being a closed platform.

In this case the user community has a general idea what an 'error 16xx' might mean, and what possible solution paths might fix the situation.

But as far as I can find out, no-one seems to know the exact problem that the error is reporting.

I guess this is just the way the cookie crumbles. We choose a closed platform, so we must accept that we will often be kept in the dark.
Such is life.

After about three days I'm still getting the error. I haven't successfully restored the iphone in question, despite having done several restores before and after with success.

I'll keep trying.
 
this works!

I ran into the same error when I tried to pwn my 1st gen 2.0.2 iphone. I tried pretty much everything discussed here and other "solutions" from google researches and nothing worked, until I ran into this:

and it finally did the trick for me!!

I basically installed iTunes 7.5 on XP and restore to 1.1.4 finally allowed for a clean restore without any errors and I basically upgraded it back to 2.0.2 on itunes 7.7.1 and it was all good.
