Phœnix is a semi-untethered jailbreak for 32-bit devices, primarily intended for devices running iOS 9.3.5. The exploit was written by Siguza and tihmstar, with jk9357 providing extensive contributions, and further assistance from Max Bazaliy and Luca Todesco. 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.

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 jk9357 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, jk9357 wrote a complaint on Twitter regarding his absence from Phœnix's credits. The issue was promptly resolved and the attribution has been corrected.
