Untethered rollback of iPhone 4. How to roll back the iOS version on iPhone, iPad

Useful tips

operating room iOS system 7 on the iPhone can only satisfy a user who is not demanding of his gadget. The system works slowly, the hardware operates at the limit of its modest capabilities, and, unfortunately, its capabilities and resources are limited third party programs, the game is often not enough. The result of running iOS 7 on the iPhone - brakes, crashes, delays and other attributes of the new operating system. First Apple time allowed users to roll back to iOS, but then the shop was closed. But, as you may have guessed, loopholes still remain.

iFaith - a reliable way to roll back the operating system

We will look at 2 methods that will allow you to roll back iOS to a lower level. And the first way is 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 the saved SHSH blobs from iOS 6.1.3. For the process to be correct, we need:

iPhone 4 with iOS 7. More modern models, such as iPhone 5, iPhone 4s, iPod player And iPad tablet, will not work with the iFaith program;
The iFaith program itself. It is worth saying that it only works on Windows. Therefore, manipulation of iOS 7 will take place using a PC;
Stored SHSH from iOS 6.1.3 or earlier;
Properly saved data from iPhone 4 (you can use iCloud);
iTunes version 11.0.5 or lower. Don't forget that you need 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 in iCloud and iTunes;
Firmware iOS 6.1.3.

The important point is that iTunes backups were not received backward compatibility. This can be understood to mean that once a rollback is made to iOS 6, it will not be possible to restore iPhone condition from an iOS 7 backup. Those programs and games that are synchronized with iCloud (if activated, Notes, Calendar, Reminders) will be restored after flashing. Co third party applications everything is purely individual. It is recommended that you transfer pictures and videos to your computer manually or save these files in Dropbox cloud. It would also be better to save the audio from the recorder to your computer or email it to yourself.

Detailed instructions for iFaith

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

Step 1

Launch iFaith on your PC and click the “OK” button. If it presses through, 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 previously used iFaith with an iPhone 4, then the saved SHSH blobs will also be available. We need to select the appropriate file to roll back from OS 7 to 6.1.3. Select and wait for loading. Then the program will ask you to specify the folder where the file will be saved. Choose a desktop. The program will notify you when SHSH for OS 6 is downloaded. Click "OK". Next, we will be informed that the file verification has been successfully completed. Click “OK” again.

Step 2

After the last operation, iFaith will again ask 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 indicate to iFaith the location where the previously downloaded iOS 6.1.3 firmware is located. If you did not download the firmware before connecting iPhone 4, then you can entrust this to iFaith. The firmware is verified, 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 is completed, the message “finished creating your custom “signed” IPSW” will appear. Remember the file name well and click “OK”. OS 7 rollback is almost here.

Step 3

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

Prepare to press and hold the Home and Power buttons after 5 seconds;
Press and hold the Power and Home buttons for 10 seconds, get ready to release the power button;
Release the “Power” button, but the “Home” button must be pressed for another 30 seconds.
After iFaith finds 4 iPhones in DFU mode, it will activate the iREB utility and tell you that your gadget has been successfully “pwned DFU” (translation you better not know). Click “OK” and “OK” again to exit the program. The rollback is almost complete, there are a couple of operations left with iTunes. The program will say that a new device has been detected in recovery mode. Click “OK” to continue.

To permanently roll back firmware 7, hold down the “Shift” button and click on “Restore iPhone”. Indicate where the firmware created using iFaith is located. Hint: The file will contain the words "signed" and "iFaith" in its name. The rollback is complete. Now iTunes starts the process iPhone recovery 4 for iOS 6.1.3 firmware. Wait for it to finish, say goodbye to OS 7 and disconnect the gadget from your computer. Once everything is restored, you can set up your phone by following the operating system prompts. Everything is ready, the rollback is completed successfully.

Second method: Redsnow program

A rollback can be performed using the Redsnow program, a version of which is available for both Windows and the 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’s 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 click “OK” and enter the phone into this mode. Without it, rollback is impossible. When DFU entry is completed, a warning window will reappear (only for locked devices). Click “Yes”. That's it, the rollback has started.

After this, the program will request the location of SHSH certificates, without which rollback is impossible. We described these files in the first method. If you saved them on your computer, then you can safely load them from there. Once the certificates are found, the rollback will be completed. The inscription “restore successful” will help you understand that you succeeded in rolling back your gadget.

As you can see, rolling back the gadget is not that difficult. The main thing is to strictly follow step by step instructions and do not skip its points. Then you can easily roll back from OS 7 to OS 6. Good luck, and remember that files may be damaged 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 an excellent solution - roll back the software to the optimal version, in your opinion. That is, if you updated to, for example, IOS 10, then you can easily install it on your iOS device 8 using the instructions below.

When is it necessary to rollback iOS?

Reasons to install more old version operating system may become 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. Happen similar problems for two reasons: either the new version of the firmware became available to users in a too crude form, with errors in the code and shortcomings, or the device that was updated was already 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 You can view which device to which firmware version can be rolled back to on the following website - http://appstudio.org/shsh. All data is located in table format.

How to roll back iOS to a specific version on an Apple device

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

iTunes installed on your computer and updated to the latest version.
Your chosen version downloaded to an easily accessible folder software, having the IPSW format. You can download it from trusted websites that distribute IOS firmware for free, for example, using the following link - http://appstudio.org/ios. Download the firmware strictly for your device model, otherwise problems will arise during installation.
A USB adapter that will connect your device to your computer.

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

Saving important data

Please note that when you roll back your device, all data, applications and media files from it are permanently erased, so it’s worth taking 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 copy 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.

Deactivating Find My iPhone

Before any actions with the device’s firmware, you must disable the “Find iPhone” function, since, otherwise, iTunes simply will not allow you to perform any actions:

Firmware rollback

If all previous preparatory work have been carried out, then you can begin the rollback itself. It doesn't matter which device you're downgrading from, or from which version of iOS you're downgrading to.

Connect the device to the computer using a USB adapter.
Log in to the system.
Go to your device's settings by clicking on the icon that looks like a phone or tablet.
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.
A window with folders will open; you need to specify the path to the firmware that you downloaded earlier.
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 or interrupt the process with any actions, otherwise the device may enter endless recovery mode.

Rollback without data loss

This rollback option also exists; it allows you to rollback without losing the data on the device. To do this, in point 4 of the “Rolling Back Firmware” section, you need to click on the “Restore” button and the “Update” button. All other steps are completely the same. The only thing worth considering is that the execution full recovery, that is, resetting the system and installing it from scratch is safer, since the chance that previous version some elements will remain much lower.

Third party rollback programs

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

After downloading and opening the program, select the Extras section.
Click on the Even More button.
In the menu that opens, go to the Restore block.
Click the IPSW button to specify the path to the previously downloaded firmware.
The notification that appears will ask you whether to cancel the modem upgrade or not. Click on the “Yes” option.
A window will open in which you will be warned that the device will now need to be put into recovery mode, close it.
Connect the device to the computer using a USB adapter and enter it into DFU Mode. How to do this is described step by step in the program itself.
If you have not previously performed such rollback operations with this program, then click on the Remote button so that it will automatically find the necessary hashes on its servers.
Done, now all you have to do is wait for the process to complete. 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 roll back 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 a special App program Admin. You can download it directly from App Store for free. Thanks to this application, you can view all available versions applications installed on your phone and roll back to them. To use the program, just select the applications to rollback and enter unique number version to which you want to drop the selected application.

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

If it were now possible to provide users of Apple devices with a way roll back from iOS 7/iOS 8 to iOS 6, we are sure that most would want to do this. And it's not even about flat design, which many still don’t like. With the release, the firmware began to work rather unstable, and older devices generally began to “slow down” noticeably. The developer published a video instruction where he demonstrated downgrade (rollback) on iOS 6.1.3 on iPad 2 and iPhone 4s.

You can roll back to iOS 6.1.3 using the tool odysseusOTA, which was released a few hours ago for Linux and OS X. The Windows version should be released a little later. Note that users don't even need to use SHSH certificates, as Apple is still signing iOS 6.1.3 for the iPad 2 and iPhone 4s.

However, only owners of jailbroken iPad 2 and iPhone 4s will be able to downgrade the firmware to iOS 6.1.3. First, you will also need to download the iOS 6.1.3 firmware IPSW file. The whole process is described in detail in the video below, although in English.

How to downgrade to iOS 6.1.3? Instructions in Russian

cd macos (or linux)
./ipsw ~ directory where the firmware file is located custom_downgrade.ipsw -bbupdate
DON'T FORGET TO ENTER -bbupdate

Don't close the terminal

Step 5: Now install the OpenSSH tweak on your device. In the terminal, enter the following commands:

./idevicerestore -t custom_downgrade.ipsw
./xpwntool `unzip -j custom_downgrade.ipsw ‘Firmware/dfu/iBSS*’ | awk ‘/inflating/(print $2)’` pwnediBSS (this is one command)

Step 6: Open section Wi-Fi settings your device and remember the device's IP address. Next, enter the following commands:

../kloader root@YOUR_IP_ADDRESS:
DON'T FORGET ":" AT THE END
Next enter yes
Enter alpine password
ssh root@YOUR_IP_ADDRESS
Enter alpine password
./kloader pwnediBSS

Step 7: The display of your gadget will turn black. Opening new tab in the Terminal and close the first tab. Now enter the following line:

./idevicerestore -w ./custom_downgrade.ipsw

Ready! Your iOS device now has iOS 6.1.3 installed.

The following people took part in the development of this method: famous hackers, like tihmstar, ih8sn0w, winocm and pod2g. Of course, not all iOS users will be able to use the method, but only a small part of them. However, the opportunity to return to skeuomorphism will appeal to many!

ATTENTION! In case of error Library not loaded: /usr/local/lib/libirecovery.2.dylib Referenced from: /Users/»username»/Desktop/odysseusOTA/macos/./idevicerestore Reason: image not found you need to re-open the terminal with clean slate and enter the commands:

sudo chown -R `whoami` /usr/local(may ask for user password).

Now install Homebrew using this command:

curl -L github.com/mxcl/homebrew/tarball/master | tar xz --strip 1 -C /usr/local

brew install libpng or brew install libpng — —universal (if there is an error)

Now start performing the rollback from the beginning using the instructions above!
