Hey guys as you all are well aware of Apple’s new policy about signing there old iOS firmwares. They have stopped signing their old firmwares as soon as new update is rolled out therefore it is now impossible for one to downgrade their iDevices to an old firmware through iTunes any more.
There is another way to downgrade with the help of your old SHSH Blobs. The main problem is that most of us were not aware that we would be facing this downgrading problems in future so we didn’t save our old firmware’ SHSHs. which made it completely impossible to downgrade by any means. BUT HEY! Good news for you guys you don’t need to worry anymore because me and my team of BlogoGist recently were performing some random experiments to downgrade Ipods on iOS 6.1.6 and lucky we found a very simple and helpful way to downgrade your iDevice to 5.1.1 and jailbreak it.
Why Downgrade ?
You guys must be wondering why downgrade to 5.1.1. You need to downgrade your iDevice if you have a broken home button. This is because if you are on 6.1.6 there is only one way to jailbreak it which is by using RedsnOw. The problem with it is that once you some how manage and get into DFU mode with broken home button the problem occurs after the jailbreak is completed. The problem that we faced was that iDevice goes into DFU mode after some time if it is placed idle. So downgrading is must if you have an ipod with broken home button. Before starting make sure you update ipod to latest firmware which is 6.1.6.
Important note before we get started.
1. This process is only for ipod touch 4 running on ios firmware 6.1.6. We will not be responsible if you use this process to downgrade any other iDevice.
2. Make sure to backup your data to itunes first you start the process because data will be lost during the process.
3. Ipod should be charged to atleast 80% before performing downgrade.
Things you need before starting:
1. Download the firmware on which currently your ipod is running. (Download firmware from Here)
2. Download ios 6.0 and 5.1.1. (You will be needing 6.0 in process)
4. A little bit of luck and faith :P.
Lets get started on how to downgrade and jailbreak iPod Touch 4 with broken home button to 5.1.1
Step 1: Extract and Open RedSn0w 0.9.15b3.
Step 2: On RedSn0w’s main window click Extras > Even more > DFU IPSW, and click OK on the pop-up dialogue.
Step 3: Browse for a valid signable IPSW file from Apple. For instance, if you have an iPod 4, you want to select the iOS 6.1.6 firmware, since that’s the only firmware that Apple is signing at the moment for this device . If you don’t have this firmware file, remember you can download firmware from felixbruns.de.
Step 4: Once you select the file, RedSn0w will go through the process of creating a new IPSW firmware file that will place your device into DFU mode upon restore. This firmware file will be placed in the same location as your original firmware file, and be named with the prefix ENTER_DFU. For instance, if I selected firmware for my iPod touch 4th generation for iOS 6.1.6, my original file should look like: this iPod4,1_6.1.6_10B500_Restore, and my new file should look like this: ENTER_DFU_iPod4,1_6.1.6_10B500_Restore.
Step 5: Connect your device to your computer and open iTunes. Select your device in the iTunes sidebar, and hold the Option key (shift on Windows; it’s shift mostly) and click the Restore button. Find your newly created ENTER_DFU IPSW file, and click OK. This will restore your device and place the device into DFU mode upon restore. You should just see a black screen once the restore is finished. If you get error 37. just ignore and minimize itunes and continue rest.
Step 6: Your device is now in DFU mode, with a freshly restored IPSW. Now proceeding to a bit tricky part of downgrading..
Step 7: Extract and Open ifaith(Run as administrator) and connect your ipod to computer. Select “Show Available SHSH caches on server”.
Step 8: When you click the option it will ask if you want to use the device which is connected, Just click OK, and it will search SHSH blobs for your ipod baseband.
Step 9: Download the SHSH blobs for firmware 5.1.1. these blobs will be placed on desktop or the path you have selected. Once it is completed go back on main screen and this time click on “Use DFU Pwner (iReb). This will put your device in pwned DFU mode.
Step 10: Open redsnow again. Click on Extras>Select IPSW> Browse IPSW iPod4,1_6.0_10A403_Restore >Select This. We do this because we want to trick redsnow to think that our ipod is runing on 6.0.
Step 11: Now click Even more> Restore> Click IPSW > browse and select ios 5.1.1 which you have downloaded.
Step 12 : Once your ipod is recognized by redsnow click on use local blobs for restore.
Step 13: Browse the blobs you have downloaded using iFaith earlier.
Then Redsnow will start to restore your ipod to 5.1.1. Sit back and relax until the process is completed. Once Ipod is restored and rebooted you will be downgraded to 5.1.1. Now finally you can jail break through simple steps.
Step 14: Extract, and right click on the absinthe-win-2.0.exe icon and select Run as Administrator. This first file is a self extracting zip file. Once you do this, a new folder will be created on your desktop called absinthe-win-2.0 with the necessary files.
Step 15: Open the absinthe-win-2.0 and right click on the absinthe.exe icon and select Run as Administrator.
Step 16: Connect your eligible iOS 5.1.1 device, and verify that Absinthe recognizes the correct name of your device.
Step 17: Click the jailbreak button on Absinthe, and let it run. You should see a progress bar.
Step 18: Eventually your device will appear as if it’s performing a restore, this is normal.
Step 19: Once the device has completed the “restore”, you should notice the Cydia icon on your Home screen.
Step 20: Once Absinthe reports that the process is complete, you can close Absinthe and disconnect your device.
Step 21: Open Cydia and let it configure itself for the first time. Congratulations, your iOS 5.1.1 device is now jailbroken untethered!
