Can I downgrade to iOS 9.1 to jailbreak?

A couple of days ago, the Chinese from Pangu launched a new jailbreak for devices with iOS 9.1, so if you bought an iPad Pro when it hit the market and you have not updated to later versions you can already enjoy it First jailbreak on Apple's new 12,9-inch iPad Pro.

The reason for launching this jailbreak is none other than the closure of the exploits used by this group of hackers in later versions of iOS. It should be remembered that currently the Latest version of iOS available in the market is 9.2.1. 

Therefore, it is the only version that at the moment Apple allows to install on its devices as long as we talk about iPhone 4s onwards or iPad 2 onwards. There are currently various web pages like ipsw.me that allow us to download any firmware to install it later on our devices. But if Apple does not sign the installation, the device will never be activated and we will never be able to use that version on our iPhone, iPad or iPod Touch.

Since Apple uses this method of digitally signing its firmwares over the Internet it is impossible to install a version higher or lower than iOS that is not being signed at that time. Every time the Cupertino people launch a new version of iOS, after a few days they quickly stop signing the previous version.

A few years ago it was possible extract digital signatures to be able to downgrade if necessary, for a while Apple closed that possibility and there is no way to downgrade to a version prior to the current one to be able to jailbreak and take advantage of the launch of this Chinese group of hackers.

This jailbreak keeps thinking about why it was released when very few people will have stayed on that version of iOS which could not be jailbroken, being able to update to later versions and take advantage of all the news that Apple has been introducing in the different updates.

According to several non-Chinese hackers, iOS 9.3 beta 6 is still vulnerable to jailbreak. Let's hope that when Apple releases the final version, which should not take long, some group of hackers is dedicated to launching it officially for all those users who enjoy it and who have had to update the device to take it to technical service, as is my If so, they can once again enjoy the almost infinite customization possibilities that it allows us.

    What we are doing with apple is that we will leave their devices to them so that they can do with them what they want.

    So many words to finally be summed up in one; IT CAN NOT. That would have been from the beginning of the news, so if people wanted to continue reading what they already know, then there they.

    What the hell did you say that you have to update to 9.2.1 when we were on iOS 9.1 and that it was recommended?

  4.   Jose said

    Go nonsense, it is already known that it cannot be, but hey now make another article that asks if I can downgrade to ios 9.0.2 to make the jailbreak, and so the silly you have written spreads more

      I was exactly going to comment on that. Here they told us that it was advisable to update and leave 9.1 behind because some Chinese had said so. What a move those of us have just played on us. Actualidad iPhone.

    Could you make a manual on how to make the iPhone volume up and another on how to lower the volume please. As I like your bullshit, nothing tease you shit, keep up with this, I encourage Ignacio that you are a champion.

    It's not that we're smart, but that they don't take us for fools either

      En Actualidad iPhone A lot of people come in who don't have much of an idea of ​​what they can or can't do with the iPhone. Hence, we often make tutorials that at first glance may seem absurd to many of you, but to the vast majority of people who use the iPhone it is not. If we only talk about news, tricks or rumors, leaving aside the tutorials or answering the questions that many users ask, we would not fulfill our objective of reporting absolutely everything related to the iPhone.

      Also, if you have entered this post, it is because perhaps you had any doubts about whether or not it can be done, or simply to clarify your doubts.

    There is a lot ready / left over in the world. I was on 8.4 with JB and also heeded the advice to upgrade to 9.2.1. I screwed up… but it was my decision. Have to wait.

    well I guess it's no one's fault for updating to iOS 9.2.1 because no one imagined that a jailbreak will appear after so long and from my point of view if you can jailbreak a more recent version is much better and I hope that the news of the jailbreak of iOS 9.3 is real and we have no other so let's wait

    I lost the jailbreak months ago due to an unknown error, something that had never happened to me before. The story, I had to restore ios, I believe 9.1 .. For now I am no longer interested in the jailbreak, I prefer to save it for ios 10, since apparently that is the only one and perhaps the last. Better wait for ios 10 and thus also look for new vulnerabilities of ios 10. I hope you are wise and think like me.

    If I benefit from the jailbreak on my ipad mini 3 and it goes luxury, I never update as the Chinese said that I don't even know who he was, one in these cases cannot get carried away by other people's talks, I stayed in my IOS 9.1 and what a great surprise it took me as well as I must have a few hundred so in good time those of us who did not pay attention to this nonsense of updating

  12.   GACER said

    IN ADDITION THAT FOOLISHNESS IS UPDATING FROM 9.1 TO 9.2 IF IT IS ALWAYS THE SAME WED ... UNLESS IT IS ALREADY A 10 SUCH YOU SEE BUT FOR FUCKING APPLE THAT WHAT YOU WANT IS TO CLOSE THE BACHES THAT THERE ARE NO FUCK I STAY IN THE 9.1 UNTIL YOU EXIT ANOTHER JAILBREAK

    How uneducated that he only dedicates himself to talking without knowing ... The "Chinese" as many of you call him was the member of the Pangu team called Windknow, and he recommended updating because until iOS 9.2.1 there was a serious problem that revealed Cookies of Safari when you connected to a WiFi network that asks for your username and password, such as restaurants or hotels, among others. Therefore, all those who are not on iOS 9.2.1 can suffer the theft of information from social networks, banks, etc. If you don't know why updating was recommended, you better not open your mouth, because all you get is to look bad trying to be smart when you don't have the slightest idea.
    Good Post Ignacio. Don't listen to people who don't deserve it. A hug.

    Well, Mr. ViCast, if you say it for me that I said "Chinese" to that man, if I have an idea of ​​what he says and I have been in this field for many years, the fact that he says that to safeguard the information of many people is appreciated , but from there to that you say that one is uneducated for ignoring him is very risky on your part, I am not connecting to any network since I have my own network in anchor with my cell phone, there many that not even knew why They had to update they did it and they lost because they did not know that the "Chinese" said it to cover that security hole and they believed that it was because the jailbreak was going to come out

    1.    ViCast4YT said

      At no time do I mean you by saying about Windknow, since not only have you said it, and by uneducated I mean people who speak without knowing, and if you have been in this world for a long time, you realize when people speak without knowing, and there are a few comments that prove it, and by this I do not mean yours, although you should already know that such an error is not silly. Here in Spain unfortunately, yes, unfortunately, if you don't have a mobile with a flat internet rate, you are nobody, and you can even see small 7-year-old children with phones like iPhone 6. When you go on vacation or you run out of megabytes at maximum speed, you are almost always going to find a way to connect to a WiFi to surf at maximum speed, and everyone with a phone at some point in their life has done it. But let it be clear that I have never named you saying that you are uneducated.

    Ok thanks Vicast for the clarification, now regarding what all these say, this page I do not think it said that the 9.1x jailbreak was already ready, what was read in countless pages was that the Chinese man said that It was advisable to update, but not for jailbreak, I saw that news a lot, and I did not pay attention for the simple reason that the more you upload the IOS, the more difficult it would be for the jailbreak to come out, as I said before I was surprised to see that one day of so many came out The jail for 9.1 and he thanked me for having waited hahaha, but there is hope that 9.3 will come to light and they will remember me that it is going to come out, but they have to be patient, but from what it comes out, I put the signature to that
