You see, when Apple is still signing a firmware version you can save the SHSH signature so that in the future if you wish to downgrade back to that firmware version it is indeed possible. This is essentially performing a replay attack, in the fact that data is being fraudulently retransmitted. To do this you can use tools like TinyUmbrella download and iFaith download. It is important to keep in mind that these tools can even save the SHSH blobs of non-Jailbroken devices.
There is unfortunately some restrictions that need to be kept in mind though. Newer devices like the iPad 2, iPad 3, iPhone 4S, iPhone 5 and iPod Touch 5G has different restrictions however, because they are not vulnerable to the limera1n exploit and are governed more-so by APTickets. Just like how Jailbreaking is becoming more and more difficult on newer Apple devices, so is downgrading.
As new exploits are constantly being found however, keep an eye on our list of how to guides shown below that will give you step-by-step instructions on how to downgrade your iPhone, iPod Touch, iPad or Apple TV to a lower firmware version. This means that the instructions are the same for all firmware versions, so you can usually just follow the instructions and just use the firmware versions for your current situation.
It can downgrade from iOS 6. Thank you! There is unfortunately no way to downgrade an A5 iOS Device back to 5. I have had as I have said 5. Of course, that's why I thought that I could restore through the new redsnow where it says remote which looks for the shsh in cydia. Xavi: Hello, this is what I opened cydia and look at the top of everything some small numbers in green that say that you have saved shsh.
If it tells you that you have 5. I have downloaded the firmwares from different sites and I always get the same response. I have no idea what this error could be due to, does anyone have any idea?
Hello, I have an iPhone 4s and I had the jailbreak but I had a problem with it, I updated it to ios 5. My question is if cydia open saved my shsh and can I do this downgrade? And the other is that I occupy the release. I have the most current gevey the ultra s. My question is if you will follow me serving? And which baseband uploads the ios 5. I hope you can help me. Any idea what else I can do? Thank you very much. The restorations cannot be done without the shsh? I have iOS 6 and I want to go back to 5.
Thank you! I don't know if you can help me… I bought a supposedly new iPhone, the problem is that I wanted to restore it from iTunes and it doesn't recognize it even though I installed iTunes, I have followed various tutorials and I still can't, it doesn't connect me to the internet, it has Chinese apps and things like that, if I follow these steps that you comment, do you think I would reset everything to be able to now connect to the internet and delete the apps or what can I do????
Be careful not to be a Chinese copy of an iPhone. Step 2: Put your device into DFU mode — this will allow you to make some necessary changes in order to downgrade the system. In order to do this, turn your device completely off, press and hold the Power and Home buttons simultaneously for 10 seconds, then release the Power button but keep holding the Home button for 10 more seconds. It might take several tries to get it right. Locate a file named hosts and open it with your favorite text editor.
Note: You might get a error during this process, which is entirely normal, throwing your device into recovery mode. Click again to start watching. Hi, Currently I got a report from a user that my app may crash when launch in iOS 7.
