TS3694 Downgrading the iphone 4

I try to downgrade my Iphone 4 from ios 6.1.2 to either 5.1.1 or 6.0.
I have a error message which is 3194 when I restore. I have never used third part software. I try to follow the step state above and try to restore a lot of time. But everytime have that error message.

I'm sorry, but Apple does not provide a downgrade path for iOS. Because downgrading is unsupported by Apple we cannot discuss it on these forums, but you can use Google to find information on how to install an older version of iOS on any iDevice.

Then you'll own nothing but a paperweight, & Apple will not help you with this. Called Activation Lock, & there is, currently, no way around it.

how to downgrade the iphone from io7

Cannot be done. Downgrading is not an option.
What is the issue you think downgrading would address? Perhaps there are other approaches.

TS3694 Hi the iphone iphone could not be restored. an unknown error occurred (56). what mean that?

Hi the iphone iphone could not be restored. an unknown error occurred (56). what mean that?

More than likely a hardware issue. You will need to take your phone into Apple.
You can also use the search function type error 56 and you'll see other threads about the issue. You can read for yourself, if other solution will help.

TS3694 the iphone " iphone :could not be restored an unkonwn error occurred(1015)

the iphone " iphone :could not be restored an unkonwn error occurred(1015)

The 1015 error is described as follows in the TS3694 article you attached:
Error 1015: This error is typically caused by attempts to downgrade the iPhone, iPad, or iPod touch's software. This can occur when you attempt to restore using an older .ipsw file. Downgrading to a previous version is not supported. To resolve this issue, attempt to restore with the latest iPhone, iPad, or iPod touch software available from Apple. This error can also occur when an unauthorized modification of the iOS has occurred and you are now trying to restore to an authorized, default state.
Note especially the part about an unauthorized modification of iOS. If your iPhone was hacked or jailbroken, you will likely never be able to restore it. Otherwise, you should plan to run iOS 4.2.1 on your iPhone 3G (and not downgrade).

It's 99% sure theat the iPhone was hacked/jailbroken to use another carrier or downgrading IOS. There's no help with this.

Plug your iPhone into iTunes and update it to the latest supported version, which is 4.2.1.

TS3694 the iphone"iphone" could not be restored. An unknown error occurred (1015)

I tried updating my iPhone 3 to the latest operating system via iTunes and once connected it would not work...
I then tried to do a system restore on the iPhone via iTunes and I was given the following error message: iphone "iphone" could not be restored. An unknown error occurred (1015)
The iPhone is now completely blank and just comes up with the Usb symbol to connect to iTunes on the screen, it won't do anything else and the same error message appears when I connect to iTunes....
Help....??
Thanks in anticipation....

This error normally appears if you attempted to downgrade or modify your iOS. See here http://support.apple.com/kb/TS3694#error1015

Hi JACOBfromINSIDEaLION,
If you are unable to get your iPhone to restore, you will want to perform a restore from recovery mode, as explained in the following article:

HT1414 Is it possible to purchase, or have apple downgrade my Iphone from IOS 6.0.1 to like IOS 5.1.1? The new software makes my Iphone lag, and the new App store is horrible. Willing to purchase a downgrade if necessary.

Would like to downgrade my IOS 6.0.1 Software to the IOS 5.1.1 Software. The new IOS for the Iphone is horrible. Too much lagging. Even after a complete restore, upgrade, no apps but the one the Iphone comes with, and just the basic things, my Iphone is horrible in speed, and loading.
I have the Iphone 4 gsm model 8GB, and I have had many of them. New, and Refurbished. Performance is all the same.
I am willing to pay Apple for a Downgrade in IOS versions, and I know shsh blobs are required, but I understand that Apple has technology that can do many things with their products. I am no fool, and am only requesting something so simple.

Downgrading of any version of iOS isn't supported by Apple at all. If you search the web, you'll find instructions that may work, but you're on your own should any problems arise. For many people it goes without problems, but for some it's reportedly bricked their devices.
Regards.
