Why do we claim that skills iPhone firmware or should every device owner have an iPad? It is not good for the owner of such an expensive and exclusive device to run in service center whenever at the software level there were difficulties in the operation of an iOS device or Apple presented new version mobile operating room iOS systems. Moreover, the process itself takes no more than 10 minutes and the user, in most cases, requires a minimum of effort.

The subject of today's instruction we will consider on iPhone example, so it will be easier for us, and for you, dear readers.

What is iPhone Firmware?

If we are talking about the firmware of an iOS device as a software component, the iPhone firmware is its software or operating system. IN Apple software for the iPhone, iPod Touch and iPad is called iOS for short, which means iPhone Operation System in English.

If we talk about flashing an iOS device as a process, flashing an iPhone is the process of restoring or updating the device software. The most commonly used term is "flashing".

iPhone flashing options

Flashing an iOS device includes 2 processes at once:

  • recovery;
  • update.

At its core, the processes are identical, that in the first, that in the second case, as a result of flashing on the iPhone, new iOS. Moreover, the concept of “new” in the case of restoring the iPhone does not refer to the version of the operating system, but to its state, in other words, “clean”.

iPhone Flashing Methods

You can reflash iPhone in 2 ways, one of them is universal, i.e. is used for both recovery and update, the second is only for updating:

  1. iPhone firmware via iTunes;

In the first case, the software is downloaded to the computer and, using the iTunes media combine, it is downloaded directly to the iOS device. Relevant for iOS 4.3.5 inclusive. For iOS 5 and above, the second method is possible, which implies iOS update directly from the device via the Internet via wireless network(wi-fi).

What is the difference between restoring an iPhone and updating it?

As we have already said, restoring or updating an iPhone refers specifically to the software component of the device.

iPhone recovery is a recovery process initial settings devices. Restoring iPhone will delete all content (photos, videos, music) and personal data ( phone book, calendar information), the device will be reset to factory settings.

In a nutshell, restoring an iPhone is resetting the device to the factory state and installing a “clean” iOS of the latest version.

An iPhone upgrade refers to the process of moving from a more old version iOS to a newer one. As a result of the update, all content, personal data and settings will remain intact and iOS will be updated to the new version.

As you can see, the fundamental difference between restoring and updating an iPhone is that as a result of the update, content and personal data are not deleted from the Phone.

The result is:

iPhone Recovery = Delete Content + Factory Reset + iOS Update

As you know, the iPhone, like any other iOS device, can be in several modes provided by the manufacturer: normal mode, (Recovery Mode) and (DFU Mode).

It is possible to restore or update an iPhone in the following modes:

  • in normal mode;
  • in Recovery Mode;
  • in DFU mode.

If we are talking about a “clean” iPhone restore via iTunes, as a result, the device will have the latest version of iOS installed, i.e. in fact, a firmware update will occur, and this is far from always necessary, especially for owners of jailbroken devices. Why? Because the jailbreak for the current iPhone firmware version appears, as a rule, with a big delay, and as a result, updating the iPhone will entail the loss of the jailbreak.

Restoring/Updating a “locked” (blocked under a specific operator cellular communication) A jailbroken iPhone entails:

  • blocking a "locked" iPhone - you will not be able to connect the device to the cellular network of another operator;
  • jailbreak loss.

Fortunately, there is a way to remove all content from it without updating the iOS version and without losing the jailbreak. We have already talked about the SemiRestore utility, which allows you to clear the contents of an iOS device and reset its settings to factory settings without loss. Take advantage if you have a “locked” or “jailbroken” device on your hands.

After the update, you will receive an iPhone with the latest iOS "on board", all user content and settings will be saved.

Update iPhone over Wi-Fi

With the advent of iOS 5.0, developers have integrated the ability to update the firmware directly into the mobile operating system. Starting with iOS 5.0 and higher, the "Software Update" menu item is available in the settings of iOS devices. The update is available only when connected to the Internet via Wi-Fi. Bandwidth internet connection cellular networks does not allow you to update iOS over 2G or 3G connection.

Restoring the iPhone 3G and 3GS is carried out according to the same principle as a rollback to the factory state of later Apple smartphones. However, sometimes a simple procedure ends with an unsuccessful firmware or the appearance of various errors - 21, 29, 1604,1015 and others. Let's see how to return the iPhone to a working state after detecting a problem during recovery.

How to restore iPhone 3G

First, let's deal with general order iPhone recovery. Everything is simple here:

If you need to restore iPhone after unsuccessful firmware, then the order of execution of the procedure will change slightly:


After the firmware is completed, iTunes will offer to restore the data from the backup. Select the "Like New" setting option. The smartphone will ask for activation - insert a SIM card into it. After successful activation, return the necessary information from the backup.

Error 29

Failure with number 29 after restoring the iPhone is mechanical in nature, so no software methods will be able to fix it. Error 29 appears in the following cases:

  • Using a non-genuine iPhone battery.
  • Charging cable damaged.
  • Burning out the SMP controller.

Often, error 29 appears on unofficial devices when trying to update or restore. Fault 29 is eliminated by replacing components with original ones. However, success is not guaranteed even in this case: error 29 sometimes appears after several battery and charging cable replacements.

If replacing iPhone components does not help, and error 29 remains, then it makes sense to check the SMARTi Power Management IC smp3i power controller.

In severe cases, failure 29 appears when the controller burns out. The problem is eliminated by replacing the damaged part with a working controller taken from the original donor. Other ways to solve error 29 do not allow you to achieve a positive result.

Error 21

Crash number 21 occurs because when restoring an iPhone 3G, the system security software prevents the device from connecting to the Apple update server. To clear error 21:


If failure number 21 occurs, recovery should be carried out in DFU mode, selecting the firmware file manually. How it's done:

  1. Enter iPhone in DFU. Connect your device to your computer.
  2. Launch iTunes and go to the device page. Hold Shift and click the Restore button.
  3. Select the firmware file and start the recovery procedure.

In rare cases, error 21, like 29, is associated with the use of a non-original battery. If the iPhone does not recover after trying to programmatically fix the problem, then try replacing the battery, error 21 will disappear. If fault number 21 continues to appear, contact the service center.

Error 1604

Failure number 1604 appears due to an interruption in the connection between the iPhone and the computer. To resolve the error:

  • Replace USB cable(use original wire).
  • Try connecting your smartphone to a different port or to a different computer.

If the USB cable and ports on the computer are in order, then try the software method for fixing error 1604. Failures with numbers 16 ** are fixed using the iReb r7 utility.


Since the iPhone 3G and 3GS are supported by the iReb r7 program, this method should help fix the crash. If the described method does not help, try fixing the error with TinyUmbrella and Redsn0w:


Restoring your iPhone after following the steps above should complete without any errors.

iPhone recovery is a standard return operation Apple smartphone to a working state after various failures. Failed firmware, incorrect jailbreak, incorrect iOS update - if you know how to restore an iPhone, you can fix almost any malfunction that occurs during the operation of this device.

Recovery order

To restore iPhone, you need to enter Recovery Mode. To do this is simple:

When the iPhone is ready for the rollback and error correction procedure, click the "Restore" button.

iTunes will independently find the current version of the firmware and install it on the smartphone, returning it to the state in which it was immediately after purchase.

Working in DFU mode

If iPhone recovery does not work in Recovery Mode, then you need to enter the device into DFU mode. This mode is used when software errors- for example, when the iPhone does not turn on. DFU mode works at the hardware level, so it helps to reset all settings even in the most difficult cases. To enter DFU mode:

  1. Connect your device to your computer.
  2. Press and hold Power and Home for 10 seconds.
  3. After counting to 10, release Power while continuing to hold the Home button.

It is difficult to enter DFU mode the first time, as nothing changes on the screen. If the recovery mode reveals itself as an iTunes icon, then the phone does not seem to turn on in DFU. Therefore, you need to look at the computer screen where iTunes is running. As soon as the iPhone enters DFU mode, a notification will appear in iTunes stating that the program has detected a device in recovery mode, and you need to reset all settings and content in order to continue working with your smartphone.

If you need to install another firmware, then hold down Shift and click "Restore". An explorer will appear, through which you need to specify the path to the previously downloaded firmware.

Recovery without a computer

If the computer is not at hand, it does not turn on, or you cannot connect your iPhone to it, then try resetting all settings through the device settings. As a result of this operation, you will get a clean smartphone without settings and user information, so be sure to make a backup before resetting. If the smartphone turns on normally:

It is not necessary to delete user files. If the iPhone turns on, then you can fix the malfunctions in its operation by simply resetting the settings. In this case, the user's personal data will remain untouched.

Recovery after a reset

If you need to restore your iPhone after resetting all settings and deleting content, then you won’t be able to do it without a backup. The presence of a backup file with information stored in the device's memory is the main point that you need to check before performing a reset. After the iPhone is reset to factory state, all personal user data is erased from it.

Create a backup before factory reset:


After the reset, the iPhone will be like new: no content or settings remain on it. To get all the information back, you need to connect the device to your computer and use iTunes to restore from a backup. Choose the most recent backup, as it stores the most up-to-date information.

You can also restore all settings after a reset through iCloud, provided that you have stored backups on the cloud. In that case, when iPhone setup you need to select the option "Restore a copy from iCloud" and specify the appropriate backup.

Recovery issues

If the phone does not turn on after normal recovery, then it makes sense to transfer it to DFU mode and try restoring with iTunes again. Don't trust iTunes this time: download official firmware and select it in the explorer window by holding Shift and clicking the "Restore" button.

Sometimes the TinyUmbrella utility helps to solve the problem that the smartphone does not turn on after resetting via iTunes. This program has an "Exit Recovery" button. If the iPhone does not turn on after recovery, you need to select it in the TinyUmbrella window and click "Exit Recovery".
