When it comes to iOS firmware, one of the most difficult things to grasp is the process of downgrading. It sure doesn't help that Apple is always making sure that everyone's firmware is up to date. If you wish to downgrade to an earlier firmware, you will need to make sure that Apple is still signing the firmware that you desire to downgrade into. Otherwise, you are stuck. But then again, if you have managed to save your SHSH blobs for the firmware you wish to downgrade to, then downgrading becomes possible even if it is isn't signed by Apple anymore. With RedSn0w v0.9.15b1, A5 devices can now be re-restored to the same iOS 5.x firmware or even to a lower iOS 5.x version. This guide will teach you How to Re-Restore A5 Devices From iOS 5.x to iOS 5.x Using RedSn0w v0.9.15b1.
Requirements to Downgrade / Re-Restore A5 Devices:
Below are some of the requirements before you can downgrade from iOS 5.x to iOS 5.x. If you don't have one of these requirements, then I'm afraid that you can't downgrade and this guide will be useless to you.
- The supported of this new Redsn0w feature are only for A5-based devices: iPhone 4S, iPad 3 or iPad 2. If you have an iPhone 5, then it is not possible to downgrade to iOS 5 at this point, or perhaps ever.
- You will need to have saved your SHSH blobs. Both for the present firmware that you are running and to the one you are trying to restore to.
- Downgrading / Re-Restoring for A5 devices is only possible within iOS 5. So for example, you can only restore from iOS 5.1.1 to iOS 5.1.1, 5.1.1 to 5.0.1, 5.0.1 to 5.1.1 etc.
- If you have upgraded to iOS 6, then you are out of luck. Except for iPad 2 owners because they can still downgrade to any iOS version, considering that they have the needed blobs saved.
- You can't downgrade if you have used Over-The-Air (OTA) updates to get to your current iOS 5.x firmware.
Steps on How to Re-Restore A5 Devices From iOS 5.x to iOS 5.x Using RedSn0w v0.9.15b1:
UPDATE X1: iPhone Dev-Team just released RedSn0w 0.9.15b2. It is recommended to use this version of the tool for this tutorial.
- First, make sure that you download the latest version of Redsn0w for your operating system. Grab it using the download links provided here. Upon downloading, extract the contents to your desktop or any desired directory.
- You will also need to download the IPSW firmware file for your current firmware and the one that you are planning to downgrade to.
- From the file you've downloaded in Step 1, double click the redsn0w.exe file to launch Redsn0w. On Windows, run the file with admin rights by right clicking on the file and selecting Run as Administrator from the context menu.
- From the main menu of Redsn0w, click Extras.
- While in the Extras menu, click Even More. And on the following screen, you should the Restore button up top, click the button.
- While on the Restore menu, click the IPSW button. Then a window will appear which will ask you to browse for the IPSW that you wish to restore to. Browse for the IPSW file and click Open.
- If you haven't connected your device, Redsn0w will prompt to connect your device. Hook up your iDevice to the computer and click OK.
- Redsn0w will ask you if you wish to point to another firmware. In case you are restoring to the same firmware, the tool will verify if you have the correct blobs saved in Cydia. If Redsn0w can't find the blobs automatically in Cydia, you have the option of using remote blobs by clicking Remote or you can search for the blobs in your computer by clicking the Local button.
- Once the IPSW and blobs selection are completed, Redsn0w will proceed to place your device into Recovery Mode.
- Redsn0w will give a warning that this procedure will update your baseband and that if you are using an unofficial unlock solution, you will lose it. To halt the process, click No. Otherwise, click Yes to proceed.
- Redsn0w will now proceed to restore your A5 device.
- Once the process is completed, Redsn0w will display a notification.
Congratulations, you have just re-restored your A5 device from iOS 5.x to iOS 5.x! This guide is of course useful if you wish to restore to iOS 5 and have a fresh iOS system without having the risk of upgrading to iOS 6 (which only has a tethered jailbreak for A4 devices only). Or perhaps those who wish to upgrade to iOS 5.1.1 where the most stable untethered jailbreak can be acquired. The process is fairly straightforward and it would be quite hard to mess things up. If you have an A4 device, you can just of course downgrade to pretty much any firmware, provided that you have the blobs required. This pretty much highlights the fact that it is always important to save your SHSH blobs every chance you get.
