Mar 15, 2017 I’ve tried to downgrade iphone 4 from ios 7.1.2 TO IOS6.1.3 using 3uTools without SHSH but am stuck at jailbreaking and It shows me (Apple mobile device will connect to DFU mode automatically) and then it says (Operation time out click YES to view details click NO to exit) but its already in DFU mode so I’m stuck in DFU mode any ideas? Nov 11, 2016  3uTools can downgrade iPhone 4 from iOS7.1.2 to iOS 4.0-6.1.3 only in the case that you have backuped the particular SHSH files before. If you don't have shsh backup, please view this tutorial 'How to Downgrade iPhone 4 from iOS7 to iOS6.1.3 without SHSH Blobs Using 3uTools?'

Notes before flash:

1. Please use iTunes to backup your important data before flash.

2. Please directly connect your device to the computer via the USB cable, and don't use the extension cable or front USB.

3. Ensure you remember your iCloud account and password, or your device can't be activated after flash.

4. If the app immediately jumps to the main menu as you click the app icon after flash, please reinstall the app.

5. Check the box of “Don't erase user’s data” so that your phone data can be stored.

6. Steps to enter DFU mode: Keep the device in normal mode or recovery mode, plug in USB cable (please don't use USB extension cable); hold HOME button, then hold power button till the screen becomes blank; release the POWER button after about 4 seconds, but keep holding the HOME button for about 10 seconds.

Step 1. Ensure you have installed the iTunes on your computer, and then download the latest version of 3uTools.


Step 2. Click Flash Jailbreak→Pro flash→Query SHSH. And then you can see which firmware versions you can flash your device to if you have backuped the SHSH files before.



Step 3. Download firmware. For example, you want to flash it to iOS6.0.1 now. Click 'Firmware'→choose 'iPhone 4'→click the downloading icon of “iOS6.0.1”.

Step 4. Click the icon on the upper right corner to enter Download center, and please wait till the download is completed.


Step 5. Click Completed→click the yellow icon of “search” to confirm the firmware location.



Step6. Click Flash Jailbreak→Pro flash→Select Firmware, and then pick up the firmware. Click Flash now to begin the flash.

Step7. Please wait till the flash is completed. When the iTunes sends a reminder in the flashing process, please cancel the box, or your device will be restored to the latest iOS version instead of 6.0.1 on iTunes!



* As to the feature of backuping SHSH file, it is involved in the toolbar of 'Advanced' on 3uTools.

1. iPhone 3GS without SHSH file backup can be downgraded to iOS4.1 using 3uTools.

2. iPhone 4 with SHSH file backups can be downgraded to any compatible firmware using 3uTools.

3. iPhone 4s/5/5s/6/6Plus/6s/6sPlus, iPad 2/3/4, iPad Pro, iPad Air 1/2, iPod Touch5/6, and iPad mini 1/2/3/4 can be downgraded from the 9.3 to 9.2.1 using 3uTools.

*Tips for other devices:

1.iPhone 4s without SHSH file backup can be downgraded to iOS 6.1.3 using odysseus-0.4.

2.iPhone 5 with SHSH file backup can be downloaded to iOS7.0.4 using odysseus-0.4.

3. iPhone 5s can't be downgraded with whichever tool.

Here’s a step-by-step guide on how to restore to an unsigned iOS firmware like iOS 11.1.2 which can be jailbroken. This guide has been written by Albanus Alain, one of our readers, who has successfully restored his iPhone 5s to iOS 11.1.2 and then back to iOS 11.0.3.

After releasing an iOS software update, Apple usually stops signing the older iOS firmware version in two weeks. Apple has used this strategy to keep jailbreakers at bay. It not only releases new software updates, that fixes the vulnerabilities used by the jailbreaks, it also stops signing the older iOS firmware file, which prevents users from downgrading back to the older iOS version that can be jailbroken. So the ability to upgrade or downgrade to an unsigned iOS firmware version can be very useful if you want to jailbreak your iPhone, iPad or iPod touch. So you could restore (essentially upgrade or downgrade) to iOS 11.1.2 which can be jailbroken using Electra jailbreak or LiberiOS jailbreak using this method.

Warning:

This tutorial is not for the faint-hearted one and there’s a possibility that you may fail and be forced to restore into latest iOS, thus losing your chance of jailbreaking. So please proceed with caution and at your own risk. Read this tutorial thoroughly over and over again until you can make sense of these steps. Upgrading or downgrading unsigned iOS can only be done when you have correct SHSH blobs for your target iOS version and the signing window for public beta iOS is still open regardless the current signed released iOS. For this tutorial, I use iPhone 5s model and will refer to iOS 11.0.3 since this version doesn’t have the terrible gyroscope bug which is present in iOS 11.1.x. To increase your chance of success you should have already jailbroken your iOS device and have 10GB free hard disk space.

Requirements:

  • Backup your iOS device. This process will erase everything on your device.
  • As mentioned earlier, for this process, you need the SHSH2 blobs for the iOS version you want to downgrade. So if you want to restore to iOS 11.1.2, then you will need iOS 11.1.2 SHSH2 blob. If you have more than one .shsh2 files, you should pick one in folder named “noapnonce” which should be something named like “1234567890123_iPhone6,1_n51ap_11.0.3-15A432_a1bcdef234abc567d8e9f012345a6789b01234c5.shsh2”. You can save the SHSH blobs for an iOS version only if Apple is still signing the firmware. If you had saved the SHSH2 blobs but have lost the link, then you can check our post on how to save SHSH2 blobs to download them.
  • For iOS 9.3.4 or 9.3.5 sideloaded PhoenixNonce.ipa from https://github.com/Siguza/PhoenixNonce/releases
  • For iOS 10+ sideloaded NonceSet1112.ipa from https://github.com/julioverne/NonceSet112
  • Download latest signed iOS .ipsw (as of this writing, iOS 11.2.6) for your iOS device model from here:
  • Download your target iOS .ipsw for your iOS device model (ex. iOS 11.1.2)
  • Download latest forked futurerestore from https://github.com/encounter/futurerestore/releases

How to Upgrade or Downgrade to Unsigned iOS Firmwares Using futurerestore

Step 1: Extract downloaded “futurerestore.zip” in a folder on your hard drive named futurerestore (for example C:futurerestore) and copy your target iOS .shsh2 blob there. Also, copy both iOS .ipsw file in this folder. To make it easy to type the command line later, you may rename the .shsh2 file to “my.shsh2”, iOS 11.0.3 .ipsw file to “restoreto.ipsw” and iOS 11.2.6 .ipsw file into “signed.ipsw”.

Step 2: Open your .shsh2 as text using Notepad and find your generator key string, something like 0xab12c34d5ef6ab7d
and type that string in PhoenixNonce app or NonceSet1112 appended with Set or enter. In this process your device may restart on its own—that’s normal. Restart your iOS device then open the app again after to make sure the value has been correctly written in your device—if the value hasn’t been shown yet, repeat this process. Sometimes the value has been correctly written but the app shows nothing. You may repeat then continue with the next steps.

Step 3: Connect your iOS device to your Windows PC, make sure iTunes is not running in the background and you have a good internet connection. Open Command Prompt then go to “C:futurerestore”. Assuming that all files are within the same folder, type the following command:

futurerestore -t my.shsh2 -i signed.ipsw restoreto.ipsw

if you haven’t changed the filenames, the command may look like this

futurerestore -t 1234567890123_iPhone6,1_n51ap_11.0.3-15A432_a1bcdef234abc567d8e9f012345a6789b01234c5.shsh2 –i iPhone_4.0_64bit_11.0.3_15A432_Restore.ipsw iPhone_4.0_64bit_11.2.5_15D60_Restore.ipsw

You will see a long verbose message after hitting Enter. Do not interrupt this process whatsoever until it’s done.

In this process, futurerestore may fail to put your iOS device into Recovery state. You may have to put your device into Recovery your own. Be aware that every time the device comes out of Recovery before the process finished, the generator key reset and you have to repeat step 1 – 3 again.

You can exit Recovery using the following command:

Downgrade Iphone 4.2.1

futurerestore.exe –exit-recovery

Wait and hopefully, nothing goes wrong during the process.

That’s it. This process should have helped you to successfully restore to an unsigned iOS firmware. You can then restore from the backup during the setup process.
