iOS 10.3.1 Kernel Exploit will allow Downgrading to iOS 10.2

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.

10.3.1 kernel exploit

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.

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?

Since it’s pretty clear now that no one has a proper 10.3.1 jailbreak except Team Pangu. They have also developed a KPP bypass that is easily worth millions.

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.

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.
