Italian hacker Luca Todesco has said that a kernel exploit in iOS 10.3.1 will allow users to downgrade to iOS 10.2. Let’s find out more about it.

Downgrading possible with iOS 10.3.1 Kernel exploit
According to the 19-year old hacker, the chances of downgrading to iOS 10.2 are higher than getting an iOS 10.3.1 jailbreak.
We require a KPP (Kernel Patch Protection) bypass to realize a jailbreak tool. This means Adam Dodenfeld’s kernel exploits will allow you to go back to iOS 10.2 instead of jailbreaking iOS 10.3.1.
Since this firmware version is jailbreak-able, you can easily use yalu102 or mach_portal to jailbreak it.
For those who don’t know, Adam Dodenfeld is an experienced security researcher from Israel. He plans to demonstrate iOS 10.3.1 jailbreak exploit at HITB Conference in August.
Luca sent out a tweet on his official Twitter handle that confirms this.
A kernel exploit alone is not enough to do a jailbreak; however for those with 10.2 blobs saved it will be possible to downgrade

How will a Kernel exploit allow downgrading?
With Dodenfeld’s 10.3.1 kernel escalation exploits, we will have the privilege of kernel code execution. This will, in turn, allow you to set nonce generator for iOS 10.2 SHSH2 Blob.
This is a huge development for users who have –
- A 64-bit iPhone, iPad or iPod
- Stashed iOS 10.2 SHSH2 Blobs
However, this does come with a few caveats. Firstly, Apple will stop signing iOS 10.3.1 by the time Adam releases his exploits.
Secondly, if Future Restore utility throws an error, you will be stuck on iOS 10.3.2.
Moreover, this requires iOS 10.2 Blobs, which a lot of users didn’t save, to work properly.
Will we get an iOS 10.3.1 Jailbreak?
I wouldn’t be surprised at all if Luca developed a jailbreak for iOS 10.3.1. This tweet even hints that he might have already bypassed the KPP and doesn’t want to release it.
@jeremyjtodd77 who’s to say I can’t? what i’m saying is that I don’t want to kill my techniques and I’m 99% sure anyone else doesn’t want to.

Jailbreaking is getting harder and harder by the day. To the best of my knowledge, Apple is clearly winning the jailbreak war.
Will we get a stable jailbreak for iOS 10.3.1? Let us know your thoughts in the comments section below.
