From Apple, many have already managed to switch to it and enjoy the innovations, however, there are also users who are unhappy and want to return the previous version operating system iOS 6 and there are many such users. Their desire is explained by the fact that someone does not like new interface, for someone, the performance of the smartphone has dropped sharply, primarily for iPhone 4, someone else for third reasons would like to return.

Work iPhone 4 on the new iOS 7 really very inexpressive, but for the owners of the "four" there is an opportunity to roll back to the old version of the firmware iOS 6.1.2 - 6.1.3.

Rollback requirements:

1. Only! iPhone 4 owners with saved SHSH blobs.
2. iFaith program ( Download).
3. iTunes for Win version 11.0.5 (Download).
4. Downloaded firmware files iOS 6.1.2(Download GSM or CDMA or GSM2012) or iOS 6.1.3(Download GSM or CDMA).

Important! Everything that you do with your iPhone 4 according to these instructions, you do at your own peril and risk.

Instructions on how to upgrade from iOS 7 to iOS 6.1.2 or 6.1.3 for iPhone 4.

1.First, you need to check the version of iTunes installed on your computer. Make sure it is 11.0.5, another version like 11.1 will not work for downgrading. Perhaps you will stand latest version on the computer, then uninstall it completely, with all related applications, also when installing iTunes 11.0.5 there may be a problem with the iTunes Music Library.xml file, go to the folder and delete it.

2. Install the downloaded iFaith program on your computer.

3. Run the iFaith program, select the location where you want to download the SHSH certificates, for example, if they were saved through Cydia, then you should click on "Show Available SHSH Caches on Server", then iFaith will download them from the server to your computer. Next, click on “Build “*signed* IPSW w / Blobs”, which will open the screen for creating custom iOS firmware.

4. Specify the location on your computer where the SHSH certificates and the downloaded iOS 6.1.2 or iOS 6.1.3 IPSW file were saved.

5. Put your iPhone 4 in DFU mode: hold down the "Power" button and the "Home" button for 10 seconds, the screen of the device should turn black, then without releasing the "Home" button, release the "Power" button, keep holding "Home" for about 10 Seconds.

6. Open iTunes on your computer and connect your iPhone 4 to it, you should see a message on the monitor that the smartphone is in recovery mode. Next, hold down the "SHIFT" key on your computer keyboard and click on the "Restore" button.

The iOS 7 operating system on the iPhone can only satisfy a user who is not picky about his gadget. The system works slowly, the hardware functions at the limit of its modest capabilities, and, unfortunately, its capabilities and resources for third-party programs and games are often not enough. The result of iOS 7 on the iPhone is brakes, crashes, delays and other attributes of the new operating system. At first, Apple allowed users to roll back to iOS, but then they closed the shop. But, as you may have guessed, loopholes still remain.

iFaith - a reliable way to roll back the operating system

We will look at 2 ways that will allow you to roll back iOS one step lower. And the first way will be the iFaith program. But we need to warn you in advance that for a successful result we will need not only this program, but also saved SHSH blobs from iOS 6.1.3. For the process to be correct, we need:

• iPhone 4 with iOS 7. Newer models such as iPhone 5, iPhone 4s, iPod and iPad will not work with iFaith;
• The iFaith program itself. Needless to say, it only works on Windows. Therefore, the manipulation of iOS 7 will take place using a PC;
• Saved SHSH from iOS 6.1.3 or earlier;
• Properly saved data from the iPhone 4 (you can use iCloud);
• iTunes version 11.0.5 or below. Don't forget to uninstall your current iTunes first. Only then can you download the old version of the program. If the rollback from iOS 7 to iOS 6 is successful, then iTunes can be updated again;
• Backup to iCloud and iTunes;
• Firmware iOS 6.1.3.

The important point is that iTunes backups are not backwards compatible. This can be understood in such a way that after a rollback to iOS 6 is completed, it will not be possible to restore the state of the iPhone from an iOS 7 backup. Those programs, games that are synchronized with iCloud (if activated, Notes, Calendar, Reminders), after flashing will recover. With third-party applications, everything is purely individual. It is recommended that you transfer photos and videos to your computer manually or save these files in the Dropbox cloud. It would also be better to save the audio from the recorder to a computer or send it to yourself by mail.

Detailed instructions for iFaith

First, we check whether all the steps described above are followed. Pay special attention to saving data from iOS 7. Now you can connect your iPhone 4 to personal computer(preferably with a native cord or 100% working) cable. Let's break the rollback of 4 iPhones with iOS 7 into 3 steps for convenience. So let's go.

Step 1

We launch iFaith on the PC and click the "OK" button. If it is pressed, it means that the iPhone 4 is connected correctly. Now we find a button with the English name "Show Available SHSH Caches on Server". The program will ask you if you want to use the connected iPhone 4. To continue, click on the "Yes" button. Now we are offered three options - we need to select the third one in the list - "Show list of available SHSH blobs on TSS server".

The program will show us all SHSH blobs from Cydia servers. If you have previously used iFaith with an iPhone 4, then the saved SHSH blobs will also be available. We need to select the appropriate file in order to roll back from 7 OS to 6.1.3. Select and wait for download. Then the program will ask you to specify the folder where the file will be saved. Choose your desktop. The program will notify you when SHSH for 6 OS is downloaded. Click "OK". Next, we will be informed that the verification of the file has been successfully completed. Click "OK" again.

Step 2

After the last operation, iFaith will ask again if you want to use the connected iPhone. We refuse him and close the program. Open it again and click OK to continue. From the available tasks, select "Build *signed* IPSW w/ blobs". Click "Browse for blobs" and find the saved SHSH blob file (we store it on the desktop). When the program accepts this file, click "OK".

Select the option called "Browse for the IPSW" and point iFaith to the location where the previously downloaded iOS 6.1.3 firmware is located. If you haven't downloaded the firmware before connecting iPhone 4, then you can entrust it to iFaith. The firmware passes the test, and then the "Build IPSW" button should appear. We click on it.

Now you need to give the program time to complete the operations, the process will not take more than 10 minutes. When the process completes, the message “finished creating your custom “signed” IPSW” will appear. Take note of the file name and click OK. The rollback of OS 7 is close.

Step 3

For the rollback to continue, you must enter the iPhone 4 into DFU mode. To do this, turn off the iPhone 4 and press the "Start" button. Now all that is required of you in order to roll back 7 OS is to follow the instructions on the screen. But there is a problem, the instruction is in English. And if there are people among our readers who are not particularly friendly with this language, then they will be able to roll back the gadget using our translation:

Get ready to press and hold down the Home and Power buttons after 5 seconds;
Press and hold the power and home buttons for 10 seconds, prepare to release the power button;
Release the "Power" button, but the "Home" button should be held down for another 30 seconds.
After iFaith finds 4 iPhones in DFU mode, it will activate the iREB ​​utility and say that your gadget has successfully "pwned DFU" (you don't need to know the translation). Click OK and OK again to exit the program. The rollback is almost complete, there are a couple of iTunes operations left. The program will say that it has detected a new device in recovery mode. Click "OK" to continue.

To finally roll back firmware 7, hold down the "Shift" button, click on "Restore iPhone". Specify where the firmware created with iFaith is located. Hint: The file will contain the words "signed" and "iFaith" in its name. Rollback completed. Now iTunes has begun the process of restoring iPhone 4 to iOS 6.1.3. Wait for completion, say goodbye to 7 OS and disconnect the gadget from the computer. When everything is restored, you will be able to set up your phone by following the prompts of the operating system. Everything is ready, the rollback is successfully completed.

Method two: Redsnow program

Rollback can be done using the Redsnow program, a version of which is available for both Windows and operating system. MAC systems OS. Choose what suits you best and download the program. Now let's launch it. We go the following way: click "Extras", then "Even more", then "Restore". Now in the “IPSW” section you need to select the firmware for your iPhone 4. After selecting the firmware, the “Prevent baseband update” window should appear, in which you need to click “Yes” (if you have a locked device, then click “Yes”, and if it is unlocked, then "No").

After these steps, a window should appear that will inform us that the iPhone with OS 7 needs to be entered into DFU mode. Feel free to press "OK" and enter the phone into this mode. Rollback is not possible without it. When the DFU input is completed, the warning window will reappear (only for locked devices). Click "Yes". Everything, the rollback is started.

After that, the program will ask for the location SHSH certificates, without which rollback is impossible. We described these files in the first way. If you saved them on your computer, then you can safely load them from there. When the certificates are found, the rollback is complete. The inscription "restore successful" will help you understand that you managed to roll back your gadget.

As you can see, rolling back a gadget is not so difficult. The main thing is to strictly follow step by step instructions and don't skip the paragraphs. Then you can easily roll back from OS 7 to OS 6. Good luck, and remember that files may suffer during flashing. So don't forget to save everything important from your phone to your computer or iCloud/iBox.

After updating to a new version of IOS, you may notice that you do not like the firmware. In this case, there is a great way out - to roll back the software to the optimal, in your opinion, version. That is, if you have upgraded to, for example, IOS 10, then you can safely install IOS 8 on your device using the instructions below.

When to rollback iOS

Reasons to install more old version operating system may be the following circumstances:

• With new firmware versions, the design changes, and not all users may like the new design.
• The most common reason is the appearance of freezes and glitches. Such problems occur for two reasons: either the new firmware version became available to users in a too raw form, with errors in the code and flaws, or the device that was updated was outdated for the loads created by new version iOS.

Please note that it is not possible to roll back any device for any version, detailed information about which device to which firmware version can be rolled back, you can view on the following site - http://appstudio.org/shsh. All data is arranged in a table format.

How to Rollback iOS to a Specific Version on an Apple Device

Before starting the process, you need to prepare the following things:

• iTunes installed on your computer and updated to the latest version.
• Downloaded to an easily accessible folder the version of your choice software, which has the IPSW format. You can download it from trusted Internet sites that distribute IOS firmware for free, for example, at the following link - http://appstudio.org/ios. Download the firmware strictly for your device model, otherwise there will be problems during installation.
• A USB adapter that will connect your device to your computer.

If all of the above conditions are met by you, then the next step is to prepare the device itself for the rollback process.

Saving important data

Please note that when you roll back a device, all data, applications, and media files are permanently erased from it, so you should take care of them. There is an option that allows you to delete files from the device, it will be discussed later in the article, but it is no less stable. You can save everything you need using a backup created as follows:

Disable password

Another important point is to disable the password and Touch ID, if it is supported and enabled on your device.

Deactivate Find My iPhone

Before any actions with the firmware of the device, you must turn off the Find My iPhone function, because, otherwise, iTunes simply will not allow you to perform any actions:

Firmware rollback

If all the previous preparatory work has been carried out, then you can proceed to the rollback itself. It doesn't matter which device you're downgrading from, or which version of IOS you'll be migrating from and to.

1. Connect your device to your computer with a USB adapter.
2. Log in to the system.
3. Go to the settings of your device by clicking on the icon in the form of a phone or tablet.
4. Hold down the Shift button on your keyboard if you're using Windows, or the Option button if you're using Mac OS. Without releasing the key, click on the "Restore" button.
5. A window with folders will open, you need to specify the path to the firmware that you downloaded earlier.
6. Wait while iTunes extracts the software from the firmware and installs it. The process can last from five minutes to half an hour, do not disconnect the device from the computer and do not interrupt the process in any way, otherwise the device may enter the endless recovery mode.

Rollback without data loss

This rollback option also exists, it allows you to rollback without losing data on the device. To do this, in paragraph 4 of the "Firmware Rollback" section, you need to click on the "Restore" button, and the "Update" button. All other steps are exactly the same. The only thing to keep in mind is that performing a full recovery, that is, resetting the system and installing it from scratch, is safer, since the chance that any elements will remain from the previous version is much lower.

Third party rollback programs

If for some reason the iTunes method does not suit you, then you can use the third-party RedSnow program. It is distributed free of charge for both Windows and Mac OS on the official website of the developer - http://redsnow.ru.

1. After downloading and opening the program, select the Extras section.
2. Click the Even More button.
3. In the menu that opens, go to the Restore block.
4. Press the IPSW button to specify the path to the pre-downloaded firmware.
5. In the notification that appears, you will be asked whether to cancel the modem upgrade or not. Click on the "Yes" option.
6. A window will open in which you will be warned that now the device will need to be put into recovery mode, close it.
7. Connect your device to your computer with USB help-adapter and enter it into DFU Mode. How to do this is described step by step in the program itself.
8. If you have not performed such rollback operations with this program before, then click on the Remote button so that it automatically finds the necessary hashes on its servers.
9. Done, now it remains to wait for the end of the process. The device will automatically update to the version you downloaded and turn on, after which you will have to go through the initial setup process.

Is it possible to rollback individual applications

If the purpose of your system rollback is to install older versions of applications, then you should not carry it out, since there is a better option - use special program app admin. You can download it directly from App Store is free. Thanks to this application, you can view all available versions of applications installed on your phone and roll back to them. To use the program, just select the applications to roll back and enter a unique version number to which you want to roll back the selected application.

So, installing an older version of software is possible on all devices from Apple, but you can not roll back to any version, but only to those that have an SHSH signature. The process can be performed both through the official iTunes app, and through third-party programs. The main thing is to download the correct firmware version and not interrupt the update process until it is fully completed.

It is possible to rollback to a previous version of the operating system. Apple has traditionally left this opportunity for a while after the release of each new OS. A day after the release of the update, the company is still issuing certificates for iOS 8.4.1.

Released on September 16, the iOS 9 update is a major software release with a long list of changes and improvements. However, many iPhone and iPad owners report problems with their devices. Failures began at the stage of downloading the update, when people could not get the promised distribution due to the unavailability of Apple services.

Owners of iOS devices complain about Wi-Fi not working correctly, missing menu items in the settings, graphical artifacts when displaying the interface, and freezing of the operating system. Among the innovations in iOS 9 are improved power consumption algorithms, but in reality, the gadget battery loses charge too intensively.

Probably, subsequent iOS 9 updates will fix these problems, but until then it makes sense to perform the downgrade procedure - rollback to iOS 8 firmware. This is only about iOS 8.4.1 version - Apple still issues digital signatures for it. It is worth remembering that the situation can change at any time.

Requirements:

• iPhone or iPad under iOS control 9.0.
• iOS 8.4.1 firmware file in IPSW format.
• iTunes 12.3 for Mac or Windows.

How to downgrade from iOS 9.0 to iOS 8.4.1:

Step 1: Download iOS 8.4.1 IPSW file from this link .

Step 2 A: Check that you have the latest version of iTunes installed. You can download iTunes 12.3.

Step 3: Make a backup of the data on the device. You can do this by going to Settings in iCloud -> Backup–> Create backup, or by connecting your iPhone or iPad to your computer and saving a backup using iTunes.

Step 4: Disable Touch ID/Password in the main settings section.

Step 5: Turn off Find My iPhone in Settings –> iCloud.

Step 6: Connect to iPhone computer or iPad with iOS 9.0 on board to your computer.

Step 7: Open iTunes and select the icon of your gadget in the top bar of the program.

Step 8: Hold down Shift (or Alt on OS X) on your keyboard and click the Restore button.

Step 9: In the program window, specify the iOS 8.4.1 firmware file downloaded in step 1.

Step 10: Wait for the procedure to complete, the OS recovery process will take some time. Now you can use your device with iOS 8.4.1.

Don't like iOS 11? Why was it updated then? … Although, this release is really special. Not everyone will go right away. Every year, Apple introduces new versions of iOS with supposedly improved features and improved optimization, but in fact, the last couple of years we have been “rubbed some kind of game”, full of bugs and shortcomings.

We, in turn, find ourselves in the place of “guinea pigs”, who must identify weaknesses and point them out to Apple for further correction. What was the recent release of the nightmarish iOS 9 worth when users around the world began to complain that their .

In principle, a similar situation was with the release of iOS 8 ... and 7 too. So, if something strange happens to your iPhone after the update, maybe it's not too late to rollback to the previous one iOS version . Today I will tell you how to do it.

The nuances of the update

But first, I would like to mention a couple of nuances related to iOS firmware and which you simply must know. As you already know, the update on more new firmware goes quite intuitively by clicking on a single button in the Settings of the phone or in iTunes on the computer.

If you want to return to a non-previous version of iOS, you must first download the firmware file with the ipsw extension from the Internet yourself, and then install it by connecting your phone to a computer.

If you suddenly decide that you can now install any old firmware, I will have to upset you. See how the situation is. During the installation of any version of iOS, your device contacts the Apple server for a digital signature.

If the server sees a version of iOS on your device that is no longer supported, it will not sign it and the installation will fail. If you don’t understand, I’ll explain with an example: if you just installed iOS 9.0, then now you can only return to 8.4.1 and that’s not a fact. With the release of new versions of iOS, Apple stops signing older versions.

Maximum “you can take one step back”. At the time of this writing, the only current firmware for all devices since the iPhone 4S is 9.0.2.

How to find out what versions of iOS are relevant today? Very simple! We go to https://ipsw.me/all and click on the model of your device.

How to rollback to a previous version of iOS

The step by step guide looks like this:

STEP 1 - Download the firmware file with the extension .ipsw from the link above:

STEP 2 - Make sure you have the latest version of iTunes

STEP 3 - If possible,

STEP 4 - B Settings iPhone turn off features: Find iPhone and Touch ID/Password

STEP 5 - Connect iPhone to computer with USB cable and launch iTunes

STEP 6 - Click on your device icon in the upper left corner of the window

STEP 7 - Hold down the Shift key ( Option/Alt on MAC), click the Refresh button in the iTunes window

STEP 8 - In the window that opens, find the firmware file you downloaded earlier (with the ipsw extension) and confirm with OK

Again, there is nothing complicated in this instruction. I hope reverting to a previous version of iOS solved your problem. Be sure to keep track of the following iOS updates, since often the first major update of the current firmware removes most of the bugs.

I do not advise anyone to upgrade to a new iOS firmware in the first days after the official release. As for me, it's better to wait a couple of weeks than to be among the "lucky ones" whose phones have turned into bricks.
