03-14-2012, 06:36 AM #13GS Stuck in Recovery Mode - Update Error (11)
I have a 3GS Factory Unlocked running on iOS 4.1.
I went for 5.1 update for the device but it stopped with the following error message:
The iPhone could not be updated. An unknown error occured (11).
iOS: Resolving update and restore alert messages
I had updated my iTunes to 10.6 prior to connecting the device. Now getting the following message on connecting to iTunes;
iTunes has detected an iPhone in recovery mode. You must restore this iPhone before it can be used with iTunes.

Got out of DFU Mode & the device rebooted to normal.
On again updating the device got the same error message.
Tried doing an update [shift+update] & restore [shift+restore] as I have ipsw file [iPhone2,1_5.1_9B176_Restore] already downloaded on my PC; but still getting the same error again & again.

Has it always been on 4.1 & the 5.1 IPSW is defiantly a stock IPSW?

Thanks Susty for your reply.
It was originally on 3.1.3 before I upgraded to 4.1 last year.
Its a factory unlocked non-jailbroken device.

Ok, in that case I'd try using your 5.1 Ipsw & create a custom firmware (preserve baseband) & try to update it that way in DFU mode & see if this still causes you an issue. Did you use a program to get it out of recovery mode?

Why a custom firmware?
My device is factory unlocked & always has been non-jb. My current baseband is 05.14.02
To get out of the recovery mode at times I have done manually by holding the home and power button & at times tinyumbrella.

I say custom because I've seen that error when baseband update has been an issue. If it works fine using that method, then it's safe to say it has an issue where the baseband is concerned.

Any where I could get step by step instruction for going about custom firmware as have never done the same before.
Also, found someone else facing the same error here: Error 11 when upgrading iPhone 4 to 5.0.1

If you download RedSnow, then when you've done that, open it, select "extras", then "Custom IPSW" & select the IPSW you downloaded & follow the instructions from there.
03-19-2012, 09:35 AM #10
And then how about updating the device with the custom IPSW?

Thanks Susty for your reply.
Further, Googling around for Error 11 have found numerous reasons from baseband to hosts files to PC hardware.
Could editing hosts file also help resolving this issue?
03-20-2012, 07:42 AM #13
Error 11 is usually caused by a missing BB from the FW.
As your device is not JB and is factory unlocked the first thing to do is confirm the ipsw is 720,402,781 bytes - if it is then it should be OK so just putting your phone in DFU and restoring that file should work.He who asks a question looks foolish for 5 minutes.

Thanks confucious for your reply.
I have re-downloaded the ipsw [iPhone2,1_5.1_9B176_Restore] from another location but both the times have got the size 703519KB.
If I am correct, that comes to 720,403,456 bytes. From where are you referring 720,402,781 bytes???
Also, I just checked the hosts file on the notebook I am using for update.
It has two hosts files; one with type as 'File' & the other with type as 'Umbrella File' (I guess tinyumbrella).
Now, both the hosts files 188.8.131.52 gs.apple.com has not been commented out.
Its without the # sign preceding the address. Could this be the issue?
03-20-2012, 11:48 AM #15
Yeah that could be one problem...you need to be able to hit the real apple servers for restore...right?
I just came up from 4.2.1 again...JB tethered with redsn0w..
Go run TinyUmbrella again go to advanced tab and make sure u have set hosts to Cydia on exit UN-checked!.....
Then close TU....
That's one way to do it...

Thanks xboxbml for your reply. So I just comment that out with a # sign preceding it in the hosts file?

The file size seems correct ( just rounded up to th next highest kb)
Your Apple redirection to cydia is commented out, so that's fine.
Now just put your phone in DFU mode and restore it and all will be fine.He who asks a question looks foolish for 5 minutes. He who doesn't ask a question remains foolish forever.

Thanks confucious for your reply. To rule out the possibility of some hardware issue, I attached the device to my notebook (A) & did a backup. Then;
1) First, I tried to save the blobs for the 3Gs but surprisingly am only able to get blobs of 4.1 & 4.3.1, which I have already. Why not for 5.1?
2) Secondly, I re-attached the device to my notebook (A) and pressed 'Update' button on prompt of newer iOS in iTunes. But again got the same message Error (11).
3) Lastly, Got my device into DFU Mode manually & hit restore. Alas, its done!
But, why I am still not able to save the blob for 5.1 for 3GS?
