IOS Upgrade

[gpote]

Hi,
I'm currently on a jailbroken/factory unlocked iPhone 4 running iOS 4.1 (8B117) with firmware 02.10.04.

I have been trying to upgrade my phone to iOS 5.1.1 but having issues with it.

I am a Mac user with OSX 10.6.4 and iTunes 10.6.3. I have downloaded iOS 5.1.1 onto my HD but haven't been able to upgrade the firmware with iTunes.
(Downloaded iPhone3,1_5.1.1_9B206_Restore.ipsw)

It keeps throwing me 3014 error earlier and now says, The iPhone ABC could not be restored. This device isn'y eligible for the requested build. I have tried editing the host files inside /private/etc but without any luck.

A few things that I have down so far which could be the reasons for the issue:
1. Jailbroken and have Cydia
2. Pressd Opt + restore and Opt + Update
3. Paused several times while downloading iOS in Safari
4. Updated iTunes from 10 to 10.6.3
5. Wrongly edited Hosts file.

I have been working for weeks on this one here ut have not been, in any way, able to work around it. Hence, I have resorted to this forum.

Any word of advice is much appreciated.

Thanks.

This is because Apple's server no longer authorizes 5.1.1 to be installed, as it's not the latest version. If you instead update to 6.0, it should work ok.

There are some ways you can try to work around this, but it can be tricky. The iPhone 4 is particularly tricky here - A5 devices are not so bad.

Use redsn0w to create a custom (ie: hacked) IPSW, and then enter "pwned DFU mode". It should then be possible to restore to the custom ipsw via iTunes.
