The Chinese Pangu team of iOS jailbreak developers has released a new version of its iOS 8 untethered jailbreak tool on Thursday. The latest update, which takes the software version to 1.2.1, addresses booting issues that many users had reported after restoring their devices from backup.

According to the Pangu team, the new jailbreak tool is bundled with the latest Cydia 1.1.16 package, which was released by its creator Jay Freeman, commonly known as Saurik, on Wednesday. Cydia 1.1.16 includes a bug fix related to iTunes backup restores, increased iOS 8 multitasking timeouts and improved App Store redirect block, iDownloadBlog reported.

Although the new Pangu 1.2.1 tool only supports Windows' operating system so far, the jailbreakers’ team said that they are working on the highly anticipated Mac version of the jailbreak tool, which could be released in the next two days. Click here to download Pangu 1.2.1.

Although the Mac version of the Pangu tool is still unavailable, users can still jailbreak iOS 8, or iOS 8.1 using Pangu on Mac OS X with the help of a virtual machine.

Meanwhile, iOS jailbreak users are recommended to update their devices to iOS 8.1 at the earliest as Apple could stop signing iOS 8.1 immediately after the release of iOS 8.1.1, which is currently in beta stage.

In addition, it has also been confirmed that the upcoming iOS 8.1.1 will kill the existing iOS 8 jailbreak. The fix was discovered on Tuesday, after the first beta version of iOS 8.1.1 was seeded to developers.

After testing the iOS 8.1.1 beta release with the jailbreak, Pangu took to Weibo to announce that the new firmware patched the vulnerabilities that were used to create the Pangu jailbreak tool.
