Firmware for iPhone 4. Flashing the fourth iPhone

With the release of mobile updates operating system Apple's iOS is much more organized than its competing product from Google. And although the number of smartphone models that support iOS hardly reaches two dozen, the company periodically limits access to current version firmware on devices that it considers “morally obsolete.”

This is due to both hardware incompatibility and device performance (for example, imagine iPhone work 3GS on iOS 10 is extremely difficult), and with a marketing solution. After all, Apple stops signing past firmware and limits access to new ones. It is impossible to install unsigned firmware (firmware with an expired digital certificate).

You will find out which iOS and which iPhone you can install on in this material.

iPhone 2G

Minimum iOS version: iPhone OS 1.0 (1A543a)
Maximum iOS version: iOS 3.1.3 (7E18)
Average update size: 91 - 245 MB

The original iPhone remains the only device on which you can install the first version of the operating system. Then they were also called like iPhone OS. Latest firmware available for installation on original iPhone- iOS 3.1.3. Downgrade is available.

Download the latest iOS versions for specific device available at IPSW.me. There you can also find out the status of the system’s subscription from Apple.

Apple Company Regularly pleases its users with the release of new firmware versions, so every owner of an Apple smartphone wonders whether it is worth updating the software on their smartphone. In this publication we will talk about how to update iOS to version 8 on the 4th iPhone, and whether it is worth doing.

iOS update options

When the company introduced the brand new iOS 8 to its users, it immediately became clear that the iPhone 4 would not be able to function normally with this version of the firmware. The fact is that this operating system is designed for mobile devices with a 2-core processor, while the 4th iPhone is equipped with only one. However, you can still install the new iOS 8 system on the Iphone 4. There are two update options for this:

• With using iTunes via computer;
• via the network.

It should be noted that after the update, only the user bears full responsibility for the functioning of his gadget.

Using iTunes on a computer

So, how to update iPhone 4 using a computer?

First you need to download the update using special application iTunes (if there are many free space) or from the official website of the manufacturer. Before connecting your device, make sure you are using the latest iTunes version, then click on Help in the menu bar and turn on Update. After this you need to do the following:

When downloading firmware using Safari, you must disable automatic unpacking. You can also use Firefox or Chrome for this.

Update via Wi-Fi

In fact, updating the software on a smartphone with using Wi-Fi- a simpler method than the previous one, but there is no complete guarantee that the update will be successful. First of all, it is worth noting that even with a high connection speed it is quite difficult to download a firmware file weighing 1 GB. In addition, do not forget about the device’s battery - the minimum charge to download a file should be at least half. If after downloading the update process begins and the device sits down and turns off, then you will have to connect the device to the computer and continue the process in iTunes.

If you plan to use this option, you must do the following:

• Check connection wireless connection and browser access.
• Enable “Settings”, go to the “General” section, select “Software Update” and click “Download and Install”. The download process starts automatically and the software update process occurs in background. You cannot run the process on a smartphone without jailbreak
• After downloading the file, click the “Install” button and accept the corresponding user agreement.

After the update process is completed, you need to make some adjustments and return all saved content from the created iPad or iTunes backup.

The software of any device becomes outdated over time. This is a normal process, since any company continues to work on its software, constantly improving it.

Firmware for iPhone 4 is no exception. The device itself cannot be called too backward in its technical configuration - you can look stylish with it even today. Plus technical parameters models (camera, processor and other indicators) are high enough for the phone to function normally.

However, the operating system on which the device runs is outdated - Apple has already released its 9th version, while the 4th generation model came with iOS 5. Of course, these updates have made the OS more productive, convenient and attractive in appearance. Therefore, some users do everything possible to bring their phone to the same condition. Simply put, they will learn how to flash an iPhone 4 phone. However, flashing may be needed not only for this.

In this article we will try to reveal as much as possible what this procedure is and why it is needed.

Each smartphone runs a specific version of the operating system. The firmware procedure means changing it, which may include either a transition to a newer generation or simply updating the existing one to the state in which the phone was released from the factory.

Someone may think that updating the iPhone 4 firmware is a complex process that can only be done by hackers or qualified service center workers, but this is not so. This is actually a fairly simple action. And Apple made sure that everyone could easily handle it, almost at home.

Why is it needed?

As already noted, one of the options for the need to update the software of your device may be the desire to simply upgrade to a newer version of its OS. This is normal, because, as we already mentioned, it may be due to advanced functionality.

So, in addition to this, the user can search for information about his iPhone 4 (how to flash it himself) in order to reduce the model to factory settings. This may be needed if you find someone else’s phone or, say, when a smartphone was given to you by a person who previously used it. Thus, you simply want to erase all information from the device that relates to other users and get a completely clean model.

Methods for flashing iPhone 4 firmware

Well, whatever dictated your desire to know how to flash an iPhone 4 (this also applies to S-modifications), we will describe how to carry out this procedure in this article. There are only two of them - “Update” and “Restore”. Both are carried out via a computer with preinstalled program iTunes and a cord connecting the smartphone to the PC; or directly on the device itself, using a local WiFi connection.

Each of the two methods of how to reflash iPhone 4s (or just 4) involves some individual characteristics. Read about the differences between them further in the text, in the sections devoted to these methods.

Recovery

Let's talk about recovery first. You can only access it if you work according to the “Computer + iTunes + phone” scheme. The “Recovery” tab can be found after your smartphone is recognized by the PC, after which a menu for managing it will appear on the monitor.

The recovery procedure itself is more complex than updating, since it involves deleting personal data from the phone. It is aimed at, as mentioned above, getting a “clean” mobile phone. It is carried out, for example, in the case of transfer or sale of an iPhone, as well as when a user is looking for how to flash a found iPhone 4.

Save information

Describing this procedure, it cannot be stressed enough that you need to be careful and save all your files in advance. It will be impossible to restore them after this step; all information from your iPhone will be lost forever. Therefore, it is not recommended to restore the device unless necessary, as an experiment, or when you have not bothered to create a backup copy of all your files (especially photos) on other media. Because, as user reviews show, this is a fairly common problem and mistake when a person confuses the process with simple update and loses all content.

Update

So, as you may have guessed, this procedure does not include deleting the user from the device, since it is only aimed at upgrading to a more recent version of the operating system.

Instructions on how to carry out this operation depend on which update method the user chooses - via a computer and iTunes or via WiFi, working with the phone itself. Those who are wondering how to flash an iPhone 4 s need not worry. Neither the first nor the second methods are particularly complex. It just all depends on the conditions in which the flashing will be carried out. This includes access to the Internet, the presence of an operating system and, of course, a cord for connecting a smartphone (you should make sure it is available).

Step by step instructions

If we describe everything step by step, we have the following picture. If we need to restore the device, we simply connect our iPhone 4 to the computer using a cable (we will describe below how to flash it without access to a PC).

Next, open the iTunes program, where in the upper right part of the screen you will see your phone menu. You need to click on it. The phone status panel will open in front of you, on which the “Restore” and “Update” keys will be located, the names of which make it obvious what they are intended for.

If you are unhappy with the performance of your iPhone 4, how to flash it is a logical question. When performing this operation using a PC, remember that you can point the program to a previously downloaded version of iOS and that the software can independently search for a more recent build. If one is actually available, iTunes will offer to install it. And remember that the answer to the question of whether it is possible to flash an iPhone 4 is negative if you wanted to return to the previous OS. The device developers have made sure that you cannot choose more old version operating system. This causes inconvenience for users who switched to iOS 8 generation, who note that it does not work correctly, freezes and periodically slows down. This was not observed on older versions of the OS.

After all this, you just need to wait. Download and installation process new system will be displayed on the phone screen, so the user can just go drink coffee at this time, for example. Actually, nothing is required from him during this process - the phone carries out all the actions independently.

Via WiFi or on a computer?

Comparing these two procedures, we only note that downloading the distribution package yourself will take longer. Downloading to PC is faster. It depends WiFi module installed on iPhone 4 (we have already described how to flash the latter in the instructions). Its transmission speed is lower than that of full-fledged computer. However, in some situations, when there is simply no access to the PC and you need to flash the firmware, this helps. So choose a method based on what you have on hand.

Cautions

This is how iPhone 4 works. You already understand how to flash it. Now let's talk about some caveats. The first is addressed to the owners non-original devices. If you are looking for how to flash a Chinese iPhone 4, then you are in the wrong place. Most often, fake smartphones (in particular, iPhone copies 4) work for (and in some cases - without it at all). Accordingly, the entire procedure described in this article is not applicable to them. Most likely, the developers who released the copy did not care about how to make updates, so the owners of such phones are out of luck.

One more note should be made for those who are looking for how to reflash an iPhone 4s that has been jailbroken (or jailbroken). If your phone was jailbroken from any carrier (for example, AT&T, Verizon or Sprint), then when you update its operating system, you will most likely lose this jailbreak. To reset all phone settings to factory settings, you can use special programs, for example, SemiRestore. However, you should not resort to the procedures described here.

There are many about this various instructions and manuals. They describe that working with such programs is usually quite simple - you need to connect the device to a computer, run such software on it and wait until all information is deleted. Upon completion, you will also receive a clean iPhone 4, however, the jailbreak should remain on it - and this is the main thing.

Why pay more?

As you can see, the iPhone 4 flashing procedure is quite simple even for inexperienced user. Anyone with minimal PC knowledge can easily handle it, since all actions are reduced to the basics.

This makes visiting a service center purpose complete removal data from the phone is meaningless. Each of us knows how to reflash an iPhone 4s, update your iOS to the latest version, reset all settings and not be too distracted from your work. So, the question arises, why pay more?

Flashing iPhone 6 firmware is an operation that is necessary for any device sooner or later. But not all owners of Apple gadgets know what it is. Of course, everyone has encountered system recovery and updating. But not everyone knows that these actions are called firmware.

In fact, there is nothing complicated about the firmware. There are several ways to carry out this procedure. And almost always the user wonders whether it is possible to do it himself. Absolutely yes. But if you don’t want to tinker, you can take the device to a service center. As a rule, in workshops, firmware is one of the standard services. But why spend money if you can do everything yourself and save money? How to restore or update an iPhone 6 - read our instructions.

Choose one of the flashing methods that suits you best and get started. If you do everything right, success is guaranteed. The only thing is that if errors appear during the operation, it is better to turn to professionals.

First, a little theory. Let us repeat once again that by firmware we mean either restoring or updating the system. The first is necessary to return the device to its original (factory) settings. The second is to install the “fresh” version of iOS.

Usually re iPhone firmware required in the following situations:

• When problems with the operating system began to appear.
• If current version iOS is not the newest, and a newer one has already been released.
• If necessary, completely erase all information from the gadget’s memory. This may be necessary when you plan to sell the phone to another owner.

Based on the essence of the recovery and update procedures, it becomes clear that they are completely different. During the first process, all data is deleted. In the second case, they are saved.

If we talk about firmware methods, the following are most often used:

• iTunes utility.
• Downloading iOS updates via Wi-Fi.

The first method will help the user in any situation. First, the “fresh” version of the operating system is downloaded to a laptop or PC, and after that it is transferred to the iPhone, and installation is done.

And when using Wi-Fi, everything is banal: a simple iOS update occurs by downloading the “fresh” version via the network.

What modes does the iPhone work in?

Mobile gadgets from Apple operate in the following modes:

• Normal.
• Recovery mode.
• Update mode.

The first mode is normal state phone. Recovery (Recovery Mode) involves flashing via backup or iTunes to the latest version.

To enter the device into this mode you need:

• Connect your iPhone to your laptop or PC using a USB cable.
• Turn off your phone.
• Turn on the device again and do not release the power button until the screen starts working.

The mode will turn on, but in this case the OS will not load into the gadget, and all data will be transferred through the cable. This operation will restore all device settings.

In update mode (DFU), the screen may be black or white. When connecting your iPhone to computer device, the latter will detect it automatically. A message will appear on the display that the iOS device has been detected by the system.

To enter your iPhone into DFU mode, you need to take the following steps:

• Connect the device to a laptop or PC using a USB cable.
• Click on Power buttons and Home (both at once).
• Release the first button while continuing to press the second.
• Wait for the gadget to enter DFU mode.

How to reflash iPhone 6 and iPhone 6S?

Let's move on to detailed description flashing methods most common among iPhone owners. The main recovery and update methods were briefly mentioned above. Now let’s take a step-by-step look at what each of them means.

So, there are 2 main methods - through the iTunes utility and using Wi-Fi.

The first method is based on downloading software components to a laptop or PC. And then the data is transferred to the iPhone with subsequent installation. This method is suitable for devices with iOS version 4.3.5 and older. For operating systems version 5 and higher, the method using Wi-Fi is more often used.

How to flash iPhone 6 via iTunes

To restore a gadget using this utility, we will need:

• The latest version of iTunes installed on your PC.
• The firmware file that is on the device at the time of the operation. Although this is not necessary, it is highly advisable to save time later.

After preparation, you can begin the recovery operation itself. The sequence of actions should be as follows:

• Disable the iPhone search function (if it was activated).
• Connecting the device to the computer via a USB cable.
• Launch the iTunes utility (usually the program starts automatically when an iOS device is detected).
• Go to synchronization settings.
• Click on Shift key and holding it down while pressing the recovery button.

After the 5th step, the operation will begin. The iTunes program will download the “fresh” version of iOS. And after that the utility will install it on mobile device. The iPhone will be in Recovery Mode during the process. Upon completion of the operation, the phone memory will return to original state. All user information will be erased.

We perform firmware via Recovery Mode and DFU

When using these methods, everything happens almost the same as when working with the iTunes utility. Only, perhaps, here the process takes longer, since before it you first need to enter the phone into one of the named modes. In turn, to do this you need:

• Enter the device into Recovery Mode or DFU.
• Connect the device to a PC or laptop via a USB cable.
• Launch the iTunes utility, which will automatically detect the iPhone in recovery mode.
• Open the firmware file prepared in advance.
• Wait for the operation to complete.

How to update iPhone: methods

Updating the operating system on an iPhone is possible through the iTunes utility. You can also do this by downloading program components via wireless communication via Wi-Fi.

The first method is similar to the restore operation. The second will allow the user to update iOS to the most current version. Using Wi-Fi convenient because it wireless way, which does not require connecting the gadget to a PC.

In order to update your Apple device via iTunes, you need to follow this algorithm:

• Connect your iPhone via a USB cable to your computer device.
• Open iTunes.
• Go to the device and click on the name the desired model gadget.
• Enter the synchronization page by selecting the update operation.
• Confirm the operation by clicking on the appropriate button.

At the end of the operation, the latest operating system will be installed on the iPhone. At the same time, it is important that absolutely all settings and data of the device will be saved.

Update iPhone 6 over Wi-Fi

Since its inception and iOS implementation With the fifth version, users of Apple gadgets now have the opportunity to update devices via Wi-Fi. Devices with such an “OS” (and with versions higher than 5th) have a section iOS updates. Now it is possible to carry out the entire procedure directly through the device interface.

But the operation can be performed in this way only if there is a working Wi-Fi connection. Through mobile networks- 2G or 3G - this, alas, is unrealistic.

The list of steps to update an iPhone via Wi-Fi includes only 2 steps:

Finally, let us remind you that during the gadget update operation, not a single file with information will disappear. All content and settings will be saved in their original form - as they were before the procedure began. But keep in mind that for locked phones this operation can be fatal. There is a danger that during the update everything will be erased needed by the user data. Therefore, it is highly not recommended to update on locked devices.

So, iPhone 6 firmware - simple procedure, accessible even to an inexperienced user. In most cases, there is no need to contact the service to carry it out. By doing everything yourself, the owner of the device will save time and money.

The operating room is constantly improving iOS systems. Bugs are eliminated, new features and capabilities appear. For the device to function properly, it is necessary to periodically install new software. This will allow your gadget to use updated or new functions. Users often have difficulties with the iPad 2 firmware procedure. But if you become thoroughly familiar with this procedure, difficulties will be kept to a minimum. Let's look into the intricacies of this issue.

You might think that it could be easier than restoring the tablet through iTunes. If you look at the general algorithm, there is nothing complicated, everything is clear. But, nevertheless, this causes difficulties for many. Separately, we can highlight the difficulty of transferring the gadget to DFU mode. In addition, it does not yet have a graphical display on the display when activated. At the same time, it is important and necessary to understand the difference between the processes of updating the OS and restoring it. These concepts can also cause confusion among the user.

Update

During the update, the iOS firmware version increases, while the owner's data and all applications installed by him are saved. Do backup copy Before performing the update, it is not necessary, but it is advisable. After all, failures may occur during work. Sometimes software failures can only be resolved through disaster recovery.

The easiest way to update is to download necessary files straight to the tablet itself. This can be done if you have good signal Wi-Fi connections. To install, you need to go to the settings and go to the “basic” section. Here you will have access to the “software updates” item. Open this item and follow the instructions provided.

Click the “install” button. Next, you will be asked to read the terms and conditions. Do not neglect to familiarize yourself with these documents. By clicking “accept” you agree to them. After will happen automatic installation updates. This method has its advantages, because it does not require the use of a computer and iTunes. The update files typically range in size from 50 to 150 MB. And you won’t have to do any extra steps.

The update method via iTunes is almost completely identical to the recovery process. In order to implement it, you need to download the iTunes program from the official website and install it. Further using USB cord connect your tablet to your PC. Use only original components, this will allow the device to transfer data faster and work longer. Open the program. IN top corner an iPad icon will appear on the left. You need to click on it.

A window will open where you will be prompted to update or restore the firmware. To start the update, you need to click the button of the same name. Upon completion of this procedure, all your personal information will be stored. The process itself will start and end automatically. At the end of the procedure, disconnect the tablet from the PC.

Recovery

Increases the OS version and deletes all personal information of the owner, since all settings are reset to factory settings. This procedure is usually done if there are any software glitches, in order to install the latest current iOS firmware in order to get a clean system and start all over again " clean slate" This procedure is performed when you want to transfer your iPad 2 to another user or intend to jailbreak the gadget.

A common question when changing firmware: is it possible to downgrade the iOS version? The answer is no. Apple officially allows the installation of only the latest released version. However, there is a short period of time (about two weeks) called the “time window”. It's exit period new version firmware, when you can still install the previous version.

It is also possible to return to the latest official iOS from a beta version of the OS. In addition to these features, hackers often release software, which allow you to downgrade your iOS version. For example, RedSn0w or TinyUmbrella. But, most often, such a rollback can only be done on old iPad versions and iPhone.

If your iPad Mini 2 has been jailbroken, do not use recovery. You now have a Cydia icon on your desktop. Restoration will initiate the "eternal apple" or "eternal restoration loop" process. This means that any device will not be able to boot normally.

If for some reason you still started the recovery, then you can bring the tablet back to life using recovery through the iTunes program. Before performing a restore, make a backup copy of your personal data, because... Once the process is complete, the data will be deleted.

Flash iPad using iTunes

Flashing is carried out in two ways: through normal mode and through low-level DFU mode. In order to carry out this process using normal mode, you need to download and install the latest version of iTunes. You can find it on the official Apple website.

On the official website you can find the latest official version of iOS for your tablet. Now you need to click on the settings icon and go to the “iCloud” section. Here you need to disable the device search function. It is not necessary to do this if you are going to flash the iPad 2 yourself. If you give the gadget to a repair service, then in order not to transfer your personal data (login and Apple password ID) disable this feature in advance.

Now you can connect your tablet via USB cable to your computer and open iTunes. The program will automatically recognize the gadget and an icon in the form of a tablet will appear in the top left corner. Click on this icon and a work area will open in front of you. If you are using Windows, then hold down the Shift key and click on the “restore” button. If you are using a Mac, press and hold Alt key and the “restore” button.

A window will open in front of you in which you need to find the downloaded firmware file. Select it and click the “open” button located at the bottom right of the window. This will start the device recovery process. After you click on “restore” all your personal data will be deleted.

Firmware for iPad via DFU mode The procedure is also not complicated. To work you will also need latest version iTunes programs. You can download it on the official website, it is available for free. Also download the latest current firmware for iPad 2.

Next, click on the settings icon and go to the “iCloud” section. Here you need to deactivate the function iPad search. This is not necessary. If you are doing the recovery yourself, you will enter your Apple ID when prompted. If you are restoring your tablet at a repair service, disable this function so as not to transfer your personal data to others.

Now you need to put the tablet into DFU mode. Connect the tablet to the computer using the original USB cable. There are two ways to activate DFU Mode:

• Simultaneously hold down two keys “Home” and “Power”. Hold them for about ten seconds. You can count to ten in your head. As soon as ten seconds have passed, press the “Power” key while continuing to press the “Home” button for about another twelve seconds.

• The second method is considered more correct. For an inexperienced user it may be more difficult. Disconnect the gadget completely and wait a couple of minutes for all processes to complete. Now hold down the “Power” button and count to three. Then press and hold the “Home” key. Keep them pressed for ten seconds. You can time or count to 10 in your head. Then press “Power” and hold the “Home” key pressed for a couple more seconds.

Nothing should be displayed on the tablet screen. If a logo or “lace” appears, it means that the mode has not been activated. You need to try again. Don’t get upset or panic, few people succeed the first time. When activated this mode iTunes will automatically notify you that your device is connected in " disaster recovery" An iPad icon will appear in the top left corner.

Next, if you are using Windows, then hold down Shift button on the keyboard and press the “restore” key. If you are using a Mac, press the Alt key and at the same time click on the “recovery” button. A window will open in which you need to find the downloaded firmware file. Specify it and click on the “open” button. It's in the lower right corner. A tab will appear on which you need to click “restore”. The process will start automatically and eventually all user data will be deleted.

Before using DFU mode, try updating the firmware to a higher soft mode Recovery mode. It allows you to do full reset and reflash the device. This mode works at the operating system level. To activate it you will need to connect USB cable to the tablet, but do not connect it to the Computer yet. Now turn off the gadget and wait a couple of minutes for all processes to complete.

Next, you need to press the “Home” key and, without releasing it, connect the cord to the PC. After some time, the display will show the connection cord and a logo in the form of a melody. After this you can release the key. Next, you need to open iTunes on your PC and flash the firmware.

Restoring a jailbroken iPad

Tablets that have been jailbroken cannot be restored using conventional methods. This will result in what is called the "eternal apple" or, essentially, endless renewal from which it is impossible to escape. In order to restore jailbroken devices, a utility called Semi-Restore was invented. It is distributed free of charge.

This program is capable of resetting the settings to factory settings without changing the firmware version and without removing the Cydia application. The application is easy to use. You need to download it, open it and connect your gadget. After that, click on the “SemiRestore” button on the screen. This program is supported by Windows and OS X.

It is not always worth resorting to this application to troubleshoot system problems. For example, if it often occurs Safe Mode, then you can fix this problem by reinstalling the Mobile Substrate package in Cydia . After using the utility, there will be nothing left on your tablet, be it repositories or personal data, so before the procedure it is better to make a copy of your personal data via iTunes.

If you are using this utility, be sure to close Xcode and iTunes. The utility also supports iOS from 5.0 to 6.1.2. While using this program, the tablet will reboot several times, so don't worry, this is normal.

Recovering iPad using SHSH

This method is suitable for older versions of gadgets. Many tablets do not support this method(these are models 4, 3, 2 and those with an Apple A5 processor). To make the firmware you need to use the TinyUmbrella application. To get started, download and install the latest version iTunes programs. Now you need to find and download Java.

Find and download on the official website required version iOS OS. Now find and download a utility called TinyUmbrella . When you open the utility archive, you need to move its contents to a folder called “programs”. Now open the utility.

In the window that opens, find the section called “Advanced” and go to it. You need to check the following boxes: “Save All Avalable...”, “Request SHSH...”, “When connecting a device...”. In the remaining items, you need to uncheck the boxes if they are selected. Then there are differences for Mac and Windows users.

For Windows

If you have prepared in advance SHSH hashes, then use the “Explorer” to go to your home folder. In the line indicating the path, add “\.shsh”. Then press the Enter key. So you went to the folder where the hashes are located. Here you need to copy the hashes that you prepared in advance. If you haven't saved anything beforehand, do the following.

Connect the tablet to the PC and specify the TinyUmbrella utility in the sitebar. IN workspace find the “Log” section " and go into it. There will be a button “Save SHSH “, you need to press it. Next, you will be presented with information about the presence or absence of hashes in Cydia. If the “log” is marked in red, it means there is no firmware for it. The mark has green, which means there is firmware.
