iphone 5 cannot be restore to ios 6.1.2

[sanlen]

Hi All,

The current iOS on my iphone 5 is 6.1.4 and i am trying to have the fresh installation of 6.1.2 so that i will be able to jailbreak it. Unfortunately, i get the error message "This iphone cannot be updated because the firmware is not compatible" after "Shift + Restore iPhone".

• I have the latest itune 11.1.3.8
• Firmware file was downloaded from Download iOS Firmware (IPSW) Files for iPhone (iphone 5 GSM version)
• I have tried with two different computer and get the same error message.
• The enclosed image is the detail of my iphone

Could you please advise what could be the problems? Your comment will be very much appreciated.

Thank,
sanlen

I'm afraid that you cannot downgrade the iOS of your iPhone 5 by any means whatsoever. If you want to jailbreak, you have no choice but to wait for the release of an iOS 7 jailbreak.

BTW, since you are talking about jailbreaking your iPhone, I've moved your post to the iPhone Jailbreaking Forum.

This thread tells exactly which iPhones can and cannot be downgraded and why. http://www.iphoneforums.net/forum/i...restore-my-iphone-x-xs-ios-x-x-x-y-y-y-56320/

Hi,

Thank for quick reply. I also try with iOS 7.0.3 and get the same error message.

The reason you also get the same message when trying to upgrade your iOS to 7.0.3 is that you can only upgrade your iOS to the latest version available; in this case, iOS 7.0.4. The iPhone 5 cannot be selectively restored. It can only be restored to the iOS version in current release.

So any possible ways for me to downgrade from 6.1.4 to 6.1.2? The reason that I need to do so because I need to install khmer unicode on my iPhone.

As I said before, there is absolutely no way at all for you to downgrade from iOS 6.1.4 to iOS 6.1.2. The only two things you can do are stay where you are or upgrade to iOS 7.0.4.

You can try this tutorial, if every step is followed exactly, you will end up with a functioning iPhone on the latest iOS version. http://www.iphoneforums.net/forum/h...afe-method-restore-current-version-ios-26019/

If it says it's still incompatible, then you're using the wrong IPSW. The iPhone 5 has 2 models, 5,1 and 5,2. One being GSM, one being world. If you're using 5,1 when you're on 5,2 or vise versa, you will receive the same issue.

shame on me.

I got the wrong firmware. I will try with the right one after downloading.

However, I am still wondering why we cannot have a clean installation of 6.1.2 on the one which is running higher version i.e: 6.1.4

Thank,

There are no bootrom exploits like that of the iPhone 4 and below, the iPod touch 4th gen and below and the iPad 1 as outlined in the sticky provided by our mod scifan57. A bootrom exploit is needed to restore a device using custom firmware. With the A5 chips and above, there are no longer any exploits that can be used in the long run. There are software methods of doing so by exploiting iTunes, but @MuscleNerd said in HITB2012 that these exploits still requires an exploit on the device, and these exploits are better used for the iOS 7 jailbreak.
