Adam Donenfeld, a security researcher behind 8 exploits corrected in iOS 10.3.2, plans to demonstrate the vulnerabilities he discovered at the HITB GSEC conference in August. His tweets first sparked rumors of a possible iOS 10.3.1 jailbreak, but Donenfeld quickly made it clear that he has no plans to take out a sealant. The man however assured that he would be happy to help a hacker wishing to develop one.

downgrade ios 10.3.1 to ios 10.2 1024x547 - Jailbreak: a flaw allows the downgrade from iOS 10.3.1 to iOS 10.2Luca Todesco, developer of Yalu jailbreak well known in the underground scene, highlighted in a tweet that exploiting the core of iOS 10.3.1 alone may not be enough to develop a jailbreak. That said, he pointed out that it may be possible to downgrade your iDevice to iOS 10.2 for those who have saved their SHSH blobs of this version. In this way, users will be able to jailbreak their iPhone, iPad or iPod Touch since iOS 10.2 can be unplugged using the Yalu jailbreak.

As a reminder, it is possible to save your SHSH2 blobs using TSS Saver, which can then be used by tools like Prometheus to upgrade to an unsigned iOS firmware version. Unfortunately, if you haven’t saved your SHSH blobs for iOS 10.2, it is no longer possible to do so because Apple has stopped signing iOS 10.2. If you are running iOS 10.3.1, it is therefore advisable to save your SHSH2 blobs as quickly as possible, because the firmware is still signed at the moment…
