Issue 4.3.2 update -- phone not eligible for requested build

More interestingly, after failing to upgrade the iPhone (see previous post: ekettoz Apr 15, 2011 6:32 AM), I tried upgrading the iPad, which fails identically:

"The iPad "Tom's iPad" could not be updated. This device isn't eligible for the requested build."

I solved the problem on my Macbook Pro. This may or may not work for you.

1. From Finder, click "Go" and then "Go to Folder"
2. Type /etc/ and press return
3. Find the document titled "Hosts" and open it.
4. Find the address "74.208.105.171 gs.apple.com" (or something to that effect) and delete it.
5. Save As to your DESKTOP. (Make sure to uncheck "if no extension is provided, use .txt")
6. BACK UP the ORIGINAL "Hosts" document to somewhere else on your computer, just in case.
7. Drag and drop the new "Hosts" document you saved to your desktop to the /etc/ folder.
8. Enter your password to verify, and that should work. (If not, replace the new "Hosts" document with the original one.)

Good Luck!

Thanks for pointing that out, though the about screen mentiones: 10.6.7, I just didn't select the right version from the ComboBox when posting.

Thanks ThatPaul, after doing what you said, he started updating.

In my case gs.apple.com was pointing at 74.208.10.249, commenting out the line in /etc/hosts took care of the problem (make sure to: sudo vi /etc/hosts).

Glad to hear it worked. I bought my current computer from a friend who use to jailbreak his iOS devices. I just happened to check the Hosts document to see if he was keeping iTunes from dialing the Mothership... And sure enough, I was right!

aye, ThatPaul's trick works. Thank you!

@ThatPaulAllen...nice one fella - worked for me

YEAAH!

same here - Paul's method did not work for me.

My iphone is new (just come from an apple store), never jailbroken and i've always the same erreur (3194) ? Any soluce for that ?

Hi there!
The mac has to flush the cached hosts, this should happen by either rebooting, but can also be forced by doing the following:
1. Go into Terminal (use spotlight if you don't know where to find it)
2. type: dscacheutil -flushcache
- If you don't have sufficient permissions for doing the command, type: sudo dscacheutil -flushcache, as and you will be prompted for the admin-password.

As for the method paul describes; be sure that there NO entry for gs.apple.com in the hosts file (what ever IP is assigned to it), as there can be several if you have done some tricking around in the hosts file before for whatever reason.

I hope this fixes the problem for you!

I checked my hosts file, installed the latest security updates for Snow Leopard, wiped my phone and restored it, still getting this message.
