Phœnix

Phœnix is a semi-untethered jailbreak for 32-bit devices, primarily intended for devices running iOS 9.3.5. It was written by S1guza and jk9357 (assisted by Max Bazaliy, Luca Todesco and tihmstar). Like its predecessor, Home Depot, Phœnix works by sideloading an IPA using Cydia Impactor. Released on 7 August, 2017, almost a year after the release of iOS 9.3.5, it brought a long-awaited jailbreaking solution to devices for which iOS 9.3.5 is the only signed version. Phœnix exploits the fact that Apple never properly fixed the vulnerabilities exploited by Home Depot (Pegasus). It is not yet known if it is compatible with iOS 8.4.1, but the IPA can be installed on iOS 8.4.1 and higher.

Controversy
The release of Phœnix was not uncontroversial and sparked a conflict between the developers and Stefan Esser (i0n1c). Esser had started a crowdfunding campaign through Kickstarter for an online iOS 9.3.5 jailbreaking course and felt betrayed by tihmstar, accusing him of backstabbing. tihmstar denied receiving help from Esser, and Luca Todesco noted that REALKJCGANGMEMBER announced a jailbreak before Esser's campaign. While Home Depot contains code written by Stefan Esser used "without his consent" according to its credits, Phœnix features another joke at Esser's expense, as the "Enable jailbreak" button from Home Depot has been renamed "Kickstart jailbreak."

After a misattribution on Phœnix's website, REALKJCGANGMEMBER declared on Twitter "[expletive] WHAT THE [expletive] DO YOU MEAN I WROTE MORE THAN HALF OF THE JAILBREAK". The issue was promptly resolved and the attribution has been corrected.
