I reported a few weeks back on an interesting new bug for 32-bit devices, which allowed you to restore them to any unsigned iOS 9.x firmware, provided you had blobs for the destination firmware.
At the time, it was thought that the bug would mainly be of use for people downgrading from iOS 9.3.5 to a lower firmware, to jailbreak with Home Depot or Pangu9. However, it turns out the bug is in fact more powerful and wide-ranging than previously thought, and may have much wider utility.
As some of you may have seen from my tweet yesterday, there is some exciting news afoot for owners of 32-bit devices on iOS 9.
A group of developers including alitek12, ee_csw and Trevor Schmitt have stated that they are working on a downgrade solution which will allow users of legacy devices to escape from iOS 9.3.5 and return to a jailbreakable iOS 9 firmware.
On Tuesday, Apple pulled the plug on signing iOS 9.3.5 for its entire iOS device lineup, and since it was the last iOS 9 release since iOS 10’s launch last month, that means you can’t downgrade your firmware anymore.
It’s worth also mentioning that the signing process was also killed for iOS 10.0.1, which means anyone who tries to restore their device(s) in iTunes will be forced to install iOS 10.0.2 or later (10.0.3 is only for iPhone 7 & 7 Plus).
The just-released iOS 9.3.5 update patches three major security vulnerabilities, reports The New York Times. Apple was alerted to the flaws just 10 days ago by security researchers Bill Marczak and John Scott Railton, and is urging users to update.
Investigators discovered that Israeli-based digital arms dealer NSO Group was using the exploits in software it sells that can track smartphones. The program can read texts and emails, track calls and location, and can record sounds and passwords.
Apple on Thursday released iOS 9.3.5 for iPhone, iPad and iPod touch. It’s a relatively small download, weighing just 40MB, and the release notes only say that it features an “important security update.” You can install the new software via the Settings app on your iOS device, or grab it from our Download section.
