iOS 8.4.1 jailbreak
iOS 8.4.1 jailbreak source code now available via GithubRedmond Pie

Italian iOS hacker and jailbreak developer, Luca Todesco, has just released the source code via Github for jailbreaking iOS 8.4.1. The code is codenamed 'Yalu', which is accompanied by a tag-line that reads "source code of an incomplete iOS 8.4.1 jailbreak".

Avid jailbreakers should note that Yalu is constrained to tethered jailbreak only as the untethered code is still a work in progress. The source code information also reveals that the incomplete iOS 8.4.1 jailbreak has been codesigned by Kim Jong Cracks, who has added the sandbox bypass with LPE to root functionality.

Advanced users can now download the source code and use it to create an executable file, which can provide tethered jailbreak on iOS 8.4.1 with root access as well as the ability to install OpenSSH on the jailbroken device, according to Redmond Pie. Given the incomplete stature of the jailbreak, Todesco has put up a public advisory notice on Twitter, saying that Cydia should not be installed on it:

Latest Yalu git commit does a jailbreak & extracts a .tgz to /. Make sure not to install cydia with it. OpenSSH is fine.

Although there is no word on the release date of the eventual public jailbreak tool for iOS 8.4.1 from Todesco, it is highly likely that he could offer a new jailbreak for iOS 8.4.1 very soon. Here is what the Italian hacker tweeted regarding the status of iOS 8.4.1 jailbreak release:

Technically speaking my i6 is now jailbroken on 8.4.1. yalu for i6 will be out very soon.

Avid jailbreakers are advised to hold off iOS 9 upgrade until further notice from the veteran members of the jailbreak community as Apple has stopped signing iOS 8.4.1 and there is no way back from iOS 9 to previous versions. It is better to wait for the veteran jailbreak developer teams like TaiG and Pangu to come out with a working jailbreak for either iOS 9 or iOS 8.4.1, before you decide to update or restore your device for some reason.

As of now, only advanced iOS users with technical knowledge of compiling the source code and creating an executable file may have any chance with jailbreaking their device on iOS 8.4.1. The source code, however, is reportedly buggy, partly functional, and does not support Cydia at the moment.
