Update in DFU mode

There are more the hard way flash an iPad 3 or another gadget model, which is called DFU (built-in firmware update) software). This method should not be used if you just want to update the tablet's operating system, for example, to iOS10. DFU mode is recommended to be used to restore the tablet if it does not turn on due to an incorrect update procedure, freezes occur when Jailbreak is installed, or errors occur directly during the recovery process. If you have no idea how to reflash an iPad in DFU mode, it’s worth saying that this method is quite complicated; to successfully complete the procedure, follow the detailed instructions:

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

We will consider the subject of today's instructions at iPhone example, it will be easier for both us and you, dear readers.

What is iPhone firmware?

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

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

iPhone flashing options

There are 2 processes involved in flashing an iOS device:

• recovery;
• update.

At their core, the processes are identical: in the first and second cases, as a result of flashing the iPhone, new iOS. Moreover, the concept “new” in the case iPhone recovery refers not to the version of the operating system, but to its state, in other words, “clean”.

iPhone flashing methods

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

1. iPhone firmware via iTunes;

In the first case, the software is downloaded to the computer and, using the iTunes media combiner, it is downloaded directly to the iOS device. Valid for iOS 4.3.5 inclusive. For iOS 5 and higher, the second method is possible, which involves iOS update directly from the device via the Internet 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.

Restoring an iPhone is the process of restoring the device to its original settings. When restoring your iPhone, all content (photos, videos, music) and personal data will be deleted ( phone book, calendar information), the device settings will be reset to factory settings.

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

Updating an iPhone refers to the process of moving from an older one. iOS versions 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 only that as a result of the update, content and personal data are not deleted from the Phone.

The result is:

Restoring iPhone = 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:

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

How to restore iPhone via iTunes?

In order to restore an iPhone via iTunes we will need:

• last iTunes version(preferably). At the time of writing, iTunes 11.1.5.5 is current. ;

iTunes window saying no update required

• pre-downloaded file with the version that is in currently installed on iPhone (optional).

It is important to know

The iPhone recovery process can be completely entrusted to iTunes, and there is no need to download the firmware file to your hard drive, however, after such a recovery, if more latest version iOS, it will be installed on the iPhone. In fact, content will be deleted, settings will be reset, and the iPhone will be updated to the new iOS.

Starting the iPhone firmware process in iTunes

Is it possible to reset an iPhone without updating iOS?

If we are talking about a “clean” iPhone restore via iTunes, the result will be the latest version of iOS installed on the device, i.e. in fact, the firmware will be updated, and this is not always necessary, especially for owners of jailbroken devices. Why? Because a jailbreak for the current iPhone firmware version appears, as a rule, very late, and as a result, updating the iPhone will entail the loss of the jailbreak.

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

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

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. Use it if you have a “locked” or “jaybroken” device.

iPhone update

We have already mentioned that there are 2 ways to update your iOS device to the latest version of iOS:

1. With connection to a computer via iTunes;
2. Directly from your iOS device via Wi-Fi.

The first method is practically no different from restoring an iPhone to the current firmware version. The second one allows you to update your iPhone to current iOS without connecting to a computer via Wi-Fi.

Updating iPhone from computer via iTunes

1. Connect your iPhone to your computer using a USB cable and launch iTunes. Go to the “Devices” menu and select your device;

Selecting a device in iTunes

2. On the page for setting up synchronization and settings for connecting the device to iTunes, left-click on “ Update". Confirm that your iPhone is updated to the latest version of iOS.

3. You can save time and not wait iOS downloads to the office iTunes folder, after downloading the current iOS to your hard drive. Using the combination " Shift+Refresh» Initiate the firmware update from the hard drive.

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

1. On iPhone, go to Settings – Basic – Software Update;

Go to software update in iPhone settings

2. Tap on " Download and install" and in the next window, accept the terms of use. Wait for the process to complete.

This is what updating an iPhone via WiFi looks like

Let us remind you once again that updating iOS does not entail the loss of user data and content and resetting settings, but it is dangerous for “jailbroken” and “locked” devices.

If you have any difficulties or errors appear when flashing iTunes, write to us in the comments, we will try to help you!

Some users of Apple products initially do not pay any attention to which version of the operating system they have installed. The idea of ​​the need for firmware/update usually arises when the previous functionality begins to get boring and you want some changes. For others, on the contrary, it is vital to update to the latest versions or test beta versions (if necessary, you can restore the device to a stable version). In this material we will tell you how you can flash an iPad (mini) without causing any harm to it.

Preparing iPad for firmware

Before you begin the firmware process, you need to make a copy of all the files stored on your iPad. This does not mean that all data will necessarily be destroyed, but it will not be a bad idea to be on the safe side. The fact is that sometimes, although rarely, some files or all at once can be erased. Well, losing a collection of your favorite music or important correspondence is not the most pleasant thing. To prevent this, you need to connect your iPad (mini) to the computer via a cable, open the iTunes program and create a backup copy of the data in the corresponding menu section.
Now consider the option simple update via wi-fi using iTunes programs(iTunes). In the program we are interested in the second line, which is called “Software update”. Actually, if it is available for download updated version operating system, there will be a mark here that allows you to go to this menu item. Next will open new screen, where you will be shown the version number offered and a link that will start the initialization. Before you start, make sure your internet connection is reliable, then just follow the instructions until you're done. necessary actions will not be fulfilled.

data synchronization and backup creation

Connecting to a computer

Although wi-fi is no surprise to anyone these days, this connection can’t be found everywhere, so it’s worth knowing how you can flash an iPad (mini) using the iTunes program via a cord. Open the program, connect your iPad using standard cord USB, just place the device in such a way that it lies on a flat surface so that there is no failure during data transfer. Next, go to the main section of iTunes, find current version iOS, which is already on your iPad (mini), in next line It will be stated which version is available for download and is the most preferable. If no problems arise, feel free to click “Update” and wait for the download process to complete.

If the operating system version does not suit you, you can download the version you need yourself. To determine it, you need to look at the back cover of the iPad (mini), find the specific model name, and download iOS for the iPad, but only from trusted sites or file hosting services. The firmware may have ZIP extension, but this will not suit us, so we rename it to the “.ipsw” format. Go back to iTunes, hold down the “Shift” key if you are using Windows and “Alt” if you are using a MAC; then a window will appear in which you will be asked to specify the path to the location of the firmware file, and then it will also identify its version and ask for consent to install. This option is also suitable for installing beta firmware.

Flashing iPad (mini) through recovery mode

Sometimes there are cases when all the above recommendations simply will not work - an error may pop up, after which the installation will be interrupted. This requires a more advanced method of flashing iOS, which requires restoring the iPad (mini) using factory settings. Let's figure out how to enable this mode.

We deactivate our iPad (mini), place it next to the computer, and then press the “Home” button. After about 5-10 seconds we connect the USB cable, which will lead to the appearance Apple logo on iPad screen(mini), and below there will be a plug and an arrow. If everything is so, then you have correctly entered recovery mode and now you can look at your computer screen.

After launch iTunes(iTunes) a warning window will appear with a link to put the iPad (mini) into recovery mode. By clicking on “Ok”, you will see the “Restore” button, after clicking on which the latest firmware version will be installed. If you want to choose which version to install on your iPad (mini), press the “Shift” button in Windows or “Alt” in MAC.

It is important to understand that the updated firmware will reset all settings to factory settings, and all data that was on the iPad (mini) will also be deleted.

To restore them, you need to take the opportunity to take them from a backup copy (see the beginning of the article). You will also have the option to choose which specific version of the copy to use. But, if, for example, you are selling your iPad (mini), then we skip the data recovery step and sell the tablet with the settings reset.

The most difficult method for flashing iPad (mini)

The developers of the iPad (mini) provided the opportunity complete shutdown Tablet software for subsequent iOS installations. This method is called DFU and is used when an error occurs during installation in recovery mode; when the iPad (mini) was jailbroken (its presence often leads to freezing during the update); when during the installation of the firmware the Internet connection was interrupted or the USB cable was disconnected, which made it impossible to start the tablet.

Firmware process via DFU mode somewhat more complicated than we described earlier. Connect the iPad (mini) to the computer, open iTunes, hold down the tablet’s launch button for a while and select “turn off” in the menu that appears. Next, hold down the iPad power button (mini) and “Home”; after 10 seconds have passed, release the power button, but still keep the “Home” button pressed for about 15-20 seconds (a message about connecting a new device should appear on the screen). The screen will be completely black, which is normal for DFU mode.

Compliance with security during firmware

Apple really created good protection their tablets from failures and intentional damage. The main threat is data loss, so you must first create backup copies for subsequent recovery. If you disconnect cables or wi-fi routers, due to which the iOS version will change, problems will appear, but they cannot be called critical. It’s worse if you manage to drop the tablet during recovery or break the socket - you won’t be able to complete the process, at least until the iPad (mini) is fully functional.

Summary

The overwhelming number of users use the most simple methods restorations that do not require any special knowledge, which means that the likelihood of errors occurring is reduced to a minimum. The DFU mode is used in cases where it is necessary to bypass some errors and restrictions that are a “stumbling block” for iTunes.

It seems that what could be easier than restoring the operating system through iTunes? Advanced users have probably learned how to do this. However, this caused no fewer messages on the forums. Every month, both experienced and new iPad owners ask how this operation is done. In today's article we will talk in detail about how to reflash an Apple tablet via iTunes.

The main goal of restoring an iOS device is to return it to its original settings with the obligatory upgrade of the operating system version. This operation is usually performed for one of the following reasons:

• failures in the software;
• installing the latest version of the operating system;
• if the user has forgotten the display lock password (do not confuse it with the same activation procedure);
• For complete cleaning systems (for example, when selling a tablet to a new owner).

Is it possible to downgrade the firmware?

The answer to this question is unequivocal - no. This is the official decision of the manufacturer. The Apple company does not allow installing versions of the operating system that differ from the current one. And this rule applies to all types of devices - smartphones, tablets, players.

However, there is such a thing as a temporary window. This is the period when, within a few weeks after the release of the newest operating system, you can roll back to the previous version.

In addition, it is also possible to return to the latest version from the beta version installed on the device. By the way, test options can be added even without an Apple account.

We are working with the beta version

Note that hackers often develop software that allows them to downgrade the operating system on any Apple device. Accordingly, for our purposes we will need to download a freely available one or buy one of these programs.

However, keep in mind that in the vast majority of cases, rolling back the operating system can only be done on older versions of tablets.

Updating and restoring – is there a difference?

When updating the operating system, all information on the iOS device is saved. During the restoration process, the gadget will return to its original settings and become completely clean. Of course, all user data will be permanently erased.

It is important to remember that you cannot update a jailbroken device. You can identify it by the Cydia symbol on the display.

Method for flashing a jailbroken device

If the user nevertheless decides to do this, in 99% of cases this leads to a loop or freezing of the apple. To successfully carry out the procedure on a jailbroken device, you must use the iTunes utility. Read on for more details.

Restoring iPad via iTunes

An operation performed using this method can be carried out in 2 ways. You can use normal mode, or you can use low-level mode, that is, DFU. The latter is usually resorted to when errors occur during normal operation.

The algorithm of user actions in normal mode will be as follows:

• Download and install the “latest” version of iTunes.
• Downloading the latest firmware version for specific model tablet
• Open the settings item and go to the “cloud” section. Disable the device search option.
• Connecting the gadget to normal mode to the PC/laptop and launch the iTunes utility.
• Waiting for the connected tablet to be recognized. The corresponding icon will pop up at the top left of the program.
• Hold down the Shift element and at the same time as this action, click on the restore button.
• In the pop-up window, select the OS IPSW file downloaded in step 2 and click on the open element. The restore operation will start.

Now you know how to flash iPad 2 via iTunes. As you can see, this operation is not difficult.

Using DFU to restore an iPad

To apply this method, follow these steps sequentially:

• Download and install the “latest” version of iTunes.
• Do the same with the desired firmware variation for your tablet model.
• Open the settings program and go to the “cloud”. Disable the device search option. This point can be omitted if you remember your ID number and password characters for it.
• Connect the device to your PC/laptop and enter it into DFU (how this is done was described in detail above).
• The utility recognizes the device. A corresponding window will pop up at the top left of the program.
• Hold Shift again and click the restore button.
• In the pop-up window, select the IPSW file downloaded in the second stage and open it. The restore operation will start.

Updating iPad: methods

The simplest and most common method of updating a tablet is when the firmware is downloaded over the air, that is, via Wi-Fi networks, without iTunes. To install it, you need to enter the settings and go to the main item. Next, select the software update item and follow the commands that will pop up on the display.

The operation of updating iOS devices in iTunes is exactly the same as in the normal mode, which was described in detail above. But there is one difference - in the program, at a certain step, the user will be required to click on the update element instead of restore.

In addition to everything mentioned, in the tenth version of the operating system one unpleasant moment was removed. Namely, the differences between variations of the same system for different versions devices. Of course, there is nothing supernatural about this, but it makes life much easier for tablet owners. And this is especially noticeable in the process of complete recovery.

How to choose firmware for iPad?

So, flashing a tablet won’t be difficult. Much more important question- choice correct option operating systems. How to choose it? Starting from the tenth version there is universal option, suitable for all models of Apple products. Let’s say that one iPSW file will correctly put a “ten” on mini, “air” and many other tablet models. Previously, each device had at least two firmware variations.

What is the benefit of all this? Of course, it’s easier to find required firmware for a tablet, and the operation itself is simplified for new owners of the device. Previously, everything was complicated by small nuances. In addition, some users (for example, those who repair tablets themselves) store firmware files on drives or in the “clouds”. And the described innovation will significantly save disk space.

From the article you learned how to flash an iPad. Moreover, you can use at least two different methods for this.

Not all users pay attention to what OS is installed on their Apple tablets. But there are device owners who carefully ensure that their devices have current version OS. Many people are interested in what iPad firmware 3 on their gadget and how to change it.

Preparatory stage

Before you start flashing your device, you need to worry about saving the information stored on the iPad. It's worth noting that you most likely won't have to recover all your data by downloading it from your PC. But it's better to be safe.

To avoid the problem of losing necessary files, make a backup copy.

There are two ways to do this: through iTunes or iCloud. After this, you can start flashing the gadget's firmware.

Flashing methods

There are several main ways to flash 3rd generation Apple tablets. So, this procedure can be performed through:

• the tablet itself;
• iTunes;
• recovery mode;

Let's consider each option in more detail.

Without iTunes

If you are interested in how to reflash an iPad quickly and without much effort, we can recommend simply updating your OS to the latest version. Below we consider the algorithm of actions:

After all the steps you will need to enter your Apple ID. When performing this procedure, the main thing is to make sure that during the update the connection to the Internet will be stable.

Via iTunes

If you want to use this method, you must:

Using recovery mode

Sometimes above mentioned methods regarding how to flash an iPad 3 do not work. The probability of such a situation occurring is 1-2%, and the application displays an error message and the installation process is interrupted. In this case, you should try to reflash the device using factory settings. The procedure will be as follows:

1. We enter recovery mode (press and hold the “Sleep/Wake” and “Home” keys at the same time).
2. Launch iTunes - a warning should appear reminding you to enter recovery mode.
3. "OK".
4. Click “Restore” (information and settings will be erased).

After all the steps, the firmware for iPad 3 will change to the latest available version OS.

It is worth recalling that new firmware will change all settings to factory settings, and will also delete all information that was on the device. In this case, a previously created backup copy will come to the rescue. After reinstallation, you will have the opportunity to choose which copy you will use. But if you want to get a completely clean tablet (for example, to sell it later), you can simply not use the recovery function.

DFU method

This method is usually used for the following reasons.
