Firmware for iphone 4 itunes. Flashing iPhone using DFU mode

Facebook

Hi all! Recovery theme iOS firmware has long been reviewed on the Internet up and down. And, to be honest, at first I didn’t want to write about something that was already online. Why produce the same type of instructions? But then it was finally decided (such is the agony of choice for the author of this blog! :)) that there was a need for this.

So why another instruction? Everything is very simple - I receive a lot of questions, both by email and in the comments, about various failures in the software securing iPhone and, in most cases, they can only be cured through software recovery. So this process is important and there is no way to bypass it, and it will be easier for me to answer your questions by simply pointing out a link to this article. Eh, looks like it was justified :) Let's go!

A few important notes:

When you restore an iPhone, absolutely everything is deleted from it. It turns out that the phone looks like you just bought it in a store.
You can only restore using a computer and iTunes. This cannot be done over the air, via iCloud or any other way.
The procedure is performed both when the device is fully operational, and if iOS system does not load (in this case you will need to enter DFU mode).

By the way, recovery is the only way Correctly remove jailbreak from iPhone.

Detailed instructions for restoring iPhone

So, complete and detailed step-by-step instruction. We launch iTunes on the computer and connect the iPhone, if everything went well, then the phone model, its firmware and other data will be displayed in the main program window. On at this stage two errors are possible:

The computer does not detect the iPhone - about this.
If the device shows no signs of life, we try.

As a result, with any successful connection we get one of two windows

And here we are interested in only one button - “Restore”. If you simply click on it, iTunes will begin to prepare the iPhone, download the latest current firmware from Apple's servers and begin installing it on the device.

Attention! Find My iPhone must be disabled!

The biggest “catch” is loading the firmware. Sometimes this process takes quite a lot a large number of time, especially with slow Internet. Plus, if the connection is not stable and the connection is possible, then iTunes will start downloading it again every time, which you will agree is not very pleasant and time-consuming.

But there is a way to speed up the recovery process. To do this, you need to download the file yourself software in .ipsw format (from any third party resource, for example w3bsit3-dns.com) and save it on your computer. Please note - for each iPhone models, will have its own file, different from others!

Now, hold down the “Shift” key on the keyboard and only then click on the “Restore” button. A window will open asking you to specify the firmware file. We select the pre-downloaded one and wait - iTunes will do everything on its own.

Why can't I restore my iPhone and what should I do?

In fact, there can be a lot of reasons. Moreover, they are associated both with a computer or device, and simply with inattention.

Here are the most basic ones:

Lack of Internet access on the PC or periodic interruptions and shutdowns.
Antiviruses, firewalls and other interfering programs normal functioning iTunes. Perhaps your security settings are configured in such a way that iTunes simply does not gain access to Apple servers.
Slow Internet connection. Not even that. Very Slow internet. This is rare now, but I remember my attempts to revive an iPhone back in 2009 using a network connection from a USB modem. I won’t describe everything, but I’ll say the result - the restoration failed.
In the case when you download the firmware yourself, see if it is exactly suitable for your specific phone model.
Check for iTunes. If yes, install latest version programs.
It is very advisable, and what’s more, be sure to use an original USB cable, non-certified ones can contribute to the appearance various errors. Non-original ones are only possible, and even then not always, and they are not suitable for flashing (restoring).
It is quite possible that the problems are already inside, that is, “iron”. There can be a lot of malfunctions - from the cable to motherboard. Remember, not or too much.

As you can see, there are really a lot of options. Please pay attention to every little thing - because it is precisely because of this that problems with restoring the iPhone may arise. Something still doesn't work out? Be sure to write in the comments - we’ll try to figure it out together!

P.S. They say that in order for the recovery to be successful and correct, you need to “like” this article. They're probably lying, but I installed it just in case... and it worked! :)

iTunes

Almost all manipulations with Apple devices, the iPhone 5S and its firmware are no exception, are carried out using a multifunctional tool for pairing the manufacturer’s devices with a PC and managing the functions of the latter -.

To restore user information, you will need a backup copy. If the smartphone was configured to synchronize with iCloud and iTunes, and/or a local backup of the device system was created on a PC disk, restoring everything important is very simple.

If there are no backups, you should, before proceeding to reinstall iOS, create a backup copy using the following instructions:

iOS update

In a situation where the goal iPhone flashing 5S is only an update to the operating system version, and the smartphone itself generally works fine; the use of drastic methods for installing system software may not be necessary.

In addition to upgrading the OS version, often improving iPhone work 5S allows upgrade installed applications, including those that do not work correctly.

Before proceeding with installing firmware on the iPhone 5S, you need to obtain a package containing components for installation. Firmware for installation in iPhone 5S are files *.ipsw. Please note that you can only install the latest version of the system released by Apple for use as the operating system of the device. The exception is firmware versions earlier than the latest, but they can only be installed within a few weeks after official release the last one. Get required package there are two ways.

Firmware process

Having completed the preparations and downloaded the desired firmware package for installation, you can proceed to direct manipulation of the device’s memory. There are only two methods available for flashing iPhone 5S to the average user. Both assume using iTunes as an OS installation and recovery tool.

Method 1: Recovery Mode

In the event that the iPhone 5S has lost its functionality, that is, it does not start, reboots, in general, does not function properly and cannot be updated via OTA, emergency recovery mode is used for flashing - RecoveryMode.

Turn off the iPhone completely.

Unlike RecoveryMode, in DFU mode reinstalling iOS is truly implemented completely. The process bypasses the system software already present in the device.

The device OS installation process in DFUMode includes the steps presented:

By recording the bootloader and then launching it;
Installation of a set of additional components;
Memory re-allocation;
Overwriting system partitions.

The method is used for iPhone recovery 5S, which have lost their functionality as a result of serious software failures and, if you need to rewrite the device’s memory completely. Besides, this method allows you to return to official firmware after operation Jeilbreak.

This is how the firmware of one of the most popular and widespread smartphones today is carried out. Apple. As we see, even in critical situations, restore the proper level iPhone performance 5S is a snap.

Everything written below will only work if you have SHSH hashes from the firmware you are going to restore to.
About what SHSH hashes are and what role they play when flashing Apple gadgets, read.
Even if you didn't save the hashes yourself, that doesn't mean you don't have them. For devices that have been jailbroken at least once, hashes for all future firmware updates can be automatically stored on Cydia servers on the Internet.
Please remember that for iPhone 3G, iPhone 3GS, iPhone 4, iPod touch 2G, iPod touch 3G, iPod touch 4G, iPad 1G and Apple TV 2G SHSH hashes can be extracted directly from the firmware currently installed on the device, even if it is no longer signed by Apple. Read about how to do this.

By this method you can restore iPhone not only to iOS version lower than the one currently installed, but also to a more recent version, provided that it is no longer current and is not signed by Apple. For current versions of iOS you should use .
You can find out which versions of iOS are current on the pages with information on the corresponding firmware, or in ours.

This instruction does not apply to devices with Apple processors A5 and newer - on iPhone 4S, iPhone 5 and everything that came later. It is impossible to upgrade the iOS version on them without upgrading the modem version.

Download from our firmware version the one you want to update to without upgrading the modem. Place the firmware file on your desktop.
Download the latest version of redsn0w for Windows.
Unzip the archive and place redsn0w on your desktop.
In the context menu of the redsn0w.exe file, select "Run as administrator":
On the redsn0w start screen, click the "Extras" button.
Then click the "Even more" button.
On the next screen, click "Restore".
Click the "IPSW" button, specify the path to the firmware file to which you want to restore without upgrading the modem.
redsn0w will ask you if you want to prevent modem elevation. Be sure to answer yes!
Then you will receive a warning about the need to enter the device into Pwned DFU mode. Click "OK".
Redsn0w will then help you enter the device into the required mode. You will need to connect your iPhone to your computer via cable and turn it off while holding Power button(at the top end), and then sliding the slider that appears. Then click "Next".
In the next step, you will need to press the Power button for 3 seconds, then hold down Home buttons and Power for 10 seconds, then release Power and hold Home for about 10 more seconds.
You will be returned to the firmware recovery screen, where the "Local" and "Remote" buttons will become available.
If you previously saved hashes using redsn0w or TinyUmbrella on your computer, you can click the "Local" button and specify the path to them. If you did not save the hashes on your computer, click the "Remote" button to have redsn0w look for hashes on the Cydia servers. If the hashes are found, the "Next" button will become available, all you have to do is click on it. Otherwise, there will be no way to restore your iPhone.
Further actions will not require your participation. redsn0w will process the firmware itself and upload it to the device. All you have to do is wait for the gadget to load in normal mode.
When the iPhone turns on, we recommend going to iOS settings, to the “Basic-About this device” section and make sure that the modem version remains unchanged.
If any error occurs and the iPhone remains in DFU mode (with the screen off, not responding to any presses), you can bring it out of there by holding down the Home and Power buttons until the apple appears on the screen.
