Do I need to upgrade to 6.0 first or something?
You can't upgrade a jailbroken device. You must restore to the newer firmware then restore your data from a backup.
So I need to install a fresh version of 5.1.1?
You want to get to iOS 6.0.1? You need to click restore in iTunes, not update.
While jailbroken? I'm doing that now.
Yes. But do keep in mind this will wipe ever thing on your device and you'll have to get your data back via a backup.
Ok. It actually went past the recovery screen but now its just a blank screen. It still says preparing iphone for restore.
If this dissent work, what about upgrading through the phones updater?
You cannot preform an OTA update on a jailbroken device. It simply will not work.
Ahh, well I just got the 1604 error after trying to "restore ". I think my host file got jacked up a while back and I couldn't figure out how to fix it.
Use Google to find out how to access and modifiy the hosts file for your system and remove all lines that have apple.com in them. Also redownload the IPSW. It may be corrupt.
You said delete everything apple?
In the hosts file, yes.
Ok did that, now how can redownload the file? I downloaded it through iTunes.
If iTunes downloaded it, the file should be fine.
Ok well its trying now.
Ok when I click restore, it says restore and update. Is that what I need to do?
I'm having the exact same issue. But I get the 1602 whether I hit update or restore.
