The unc0ver jailbreak may soon support A12/A13 devices running iOS 13 - iOS 13.3!

Developer Pwn20wnd is planned to integrate a new exploit discovered by Brandon Azad into the popular jailbreak utility. If successful, this would introduce jailbreak support for the iPhone XR, XS, XS Max, 11, 11 Pro, and 11 Pro Max.

Azad announced the exploit on Twitter yesterday:

If you're interested in bootstrapping iOS kernel security research on A13, keep an iPhone 11 on iOS 13.3. I will be releasing a proof-of-concept exploit that provides kernel read/write on iPhone12,3 17C54.

This led to an immediate recommendation from Pwn20wnd to downgrade to iOS 13.

If you are on iOS 13.3.1 with an A12/A13 device, downgrade to iOS 13.3 ASAP.

Then earlier today, Pwn20wnd revealed plans to integrate the exploit into the unc0ver jailbreak.

FWIW, I will be working on updating the unc0ver jailbreak for iOS 13.0-13.3 as soon as the new kernel exploit is available. For now, make sure that automatic software updates are disabled on your device and save blobs for iOS 13.3.

So far, I have found 3 changes that break my existing implementation of tweak injection on iOS 13 A12+ and I have already bypassed one of them. The underlying technique behind PAC-Less seems to be unaffected though so that's good.

Jailbreak ain't that good anymore, nobody's taking about it but nice to see pawn still fighting the good fight.

I thought that you can’t save blobs on A12, am I wrong?

Blobs on other name is SHSH2 which is the key that Apple give to any device to install an iOS, So if you keep a copy of the key to iOS 13.3 then you’ll be able to install 13.3 even when Apple closes the door on that one. The thing is that Apple always fight jailbreaking so now it’s much harder, for a long time after your first jailbreak since the beginning of jailbreaking Cydia used to save blobs automatically to all, now Apple created a much smarter key which can be saved only while Apple still signing that iOS.
