iOS hacker Luca Todesco aka @qwertyoruiop, has just announced the release of the source code called “Yalu”, for jailbreaking iOS 8.4.1. Yalu comes with the following tag-line – ‘source code of an incomplete jailbreak for iOS 8.4.1’.
Jailbreak fans should be aware that the untethered code is still a work in progress and that Yalu is only constrained to a tethered jailbreak. Also revealed in the source code information is that the incomplete iOS 8.4.1 was co-designed by Kim Jong Cracks, who is responsible for adding the sandbox bypass with LPE to root functionality.
Advanced jailbreak users are now able to download and use the source code to create an executable file, which, besides providing tethered jailbreaks on iOS 8.4.1 with root access, also has the ability to install OpenSSH on the jailbroken device. Because the jailbreak is still incomplete, Todesco has advised on Twitter 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.

Unless you know what you’re doing and have the technical knowledge to download and execute the code from GitHub, we strongly advise that you don’t attempt a jailbreak until a user-friendly tool has been released. In its current form, this jailbreak requires advanced knowledge of compiling then executing the source code on your device. And keep in mind that it’s still quite buggy at best and at this point doesn’t even support installing Cydia. There’s every possibility that you’ll end up doing more harm than good to your device. But, the good news is that this jailbreak is real and will arrive in the proper form very soon. So, even though we have no word on the release date of the public jailbreaking tool for iOS 8.4.1, we expect we’ll be seeing the release of a new jailbreak very soon. The following is the tweet from the Italian hacker on the current status of the 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 — Luca Todesco (@qwertyoruiop) October 7, 2015
Users keen to jailbreak their device are advised to hold off iOS 9 upgrade until advised by the jailbreak community because Apple is no longer signing iOS 8.4.1 and there’s no way back to previous versions from iOS 9. So, before you make a decision on updating or restoring your device it’s definitely preferable to wait for the experienced jailbreak developer teams like Pangu and TaiG to release a working jailbreak for either the iOS 8.4.1 or iOS 9.
As it stands at the moment, the only people with any chance of successfully jailbreaking their device on iOS 8.4.1 would be experienced iOS users with technical knowledge of compiling the source code and creating an executable file. However, keep in mind that the source code is only partly functional, probably buggy, and won’t support Cydia at this time.
