I tried to download iOS 7.0.3 on my iPhone 4S (it was previously Dad's, all his data, apple id etc still on there :O argh), but it failed. I looked for information online to solve this problem, and the solution was to manually update my phone on iTunes. I was going to do that, but -- I decided to restore my phone first, because I was sick of all my dad's large data, and wanted to start clean. I tried to restore my phone, but my phone asked for a restrictions passcode. I vaguely remember going on the phone (at the time it was Dad's) and poking around in the restriction settings and creating a restriction passcode. I do not know why I did it, I didn't restrict anything however. So anyways, I've forgotten my restrictions passcode and want to restore my phone another way -- I looked online, I have to manually restore the phone on iTunes. So now the things I have to do are: Restore my phone and update my phone manually on iTunes. I tried to do the update to iOS 7.0.3 first, this comes up: "There was a problem downloading the software for the iPhone "Krishna Narayanan" An unknown error occurred. (-23) " Okay, so now I decided to restore my phone as updating isn't working and I may as well strike a goal off my hit list... BUT, when I click the "Restore iPhone..." button, it comes up with a window and on it a button Restore AND Update . I click that, and the same error message (from the unsuccessful updating, obviously) ! It's obviously the update, it's causing an error. Why can't I just restore the phone?!?! Oh well, so now I can't do either of the two.
Oh, when I press "More information" on the error message window, I tried ALL the solutions on the link
(restart, removing other USB devices, uninstalling Norton anti-virus temporarily, downloading the latest iTunes - done already: 11.1.2) several times.
I tried recovery mode and DFU (Direct Firmware Upgrade) mode, those aren't working either - the same 23 error message comes up! And a site said that if recovery mode wasn't working, DFU was the second option! But I am out of options now! I really want to restore and update my phone, how to force it??
