Upgrade to iOS 4.2 1013 error

Thanks Dave01978. That worked for me too.

You'll need to be root to edit the /etc/hosts file.

Dear sailborg333,

I have 7 Mac computar at home and i have try With two of them and don't work.
I'm going to try Dave's right now.

I'm very worry, I'm 7 hours with my iPhone offline because this 1013 error!!!!!!

WORKED! Thanks!
Can you tell me WHAT i just did? Do I need to go back to the hosts file and replace that line?

I solve my error 1013. I open Tinyumbre... and... advance tab, uncheck "Set Host to Cydia on Exit(If you need clean restore from Apple uncheck this box)" Click apply changes, closed Tinyumbrell...and open iTunes, upgraded and iTunes restore from my last backup.
Hope this help someone else, cause i was getting nuts with this error.

you have to have root access to edit the hosts file. Easiest way is to type:

sudo nano /etc/hosts

into terminal and then delete or comment out the line like this:

#74.208.10.249 gs.apple.com

Then hit ctrl-x and y to save.

Thank you so much!

I cant be absolutely sure this is what happens but heres what I think goes on. Apple verifies the software when you install it, by removing the line in /etc/hosts itunes no longer knows where to go for verification. I think it then defaults to something else (maybe a hash of the file?) and can continue on. Again I'm not sure that this is what happens but its probably close. You can put that line back in afterwards so that nothing gets messed up in the future.

dave what is sudo nano? and what do you mean by first progress bar when it says extracting that bar?

when I try to delete that line of gs.apple.com, I get an error which says that the file can't be saved

dave, i dont understand how to get to do this on the phone... its stuck i can't get into a dam thing

the only thing is i cant access terminal my iphone is stuck in recovery mode

sudo = elevates the command following it to root.
nano = a command line editor

Once the file is extracted then remove the line. You can edit the file while everything is happening, just don't save it until the extraction completes.

do i need nano to do this?

Me and my brother had the same problem. We got update when I tried in another computer. Try the same. Good luck!

I just realized that not everyone is using a mac who has an iphone, these instructions are for a mac running osx. All the commands were to be run on the computer syncing with the iphone. For windows users the hosts file is located here:

%SystemRoot%\system32\drivers\etc\

Try using "notepad" or whatever its called on windows to modify the file and if the line that I said to erase is there then it should work, else; I dont know 😟
