Apple Inc. developed one of the toughest security systems on mobile devices, but teams of hackers are doing their best to decipher the tech giant's code to release the jailbreaks for Apple iOS 9.1 and iOS 9.2 as soon as possible.

Jailbreaking is described as the process of eliminating restrictions imposed by Apple's operating system on devices. Hackers create tools and software to access the tech giant's system, and for users to install apps that are not available to Apple App store.

As of now, hacking groups like Team Pangu and TaiG are developing the jailbreaking tools, and they are aiming to release it by the end of the year.

Team Pangu recently released the semi-jailbreak online script for iOS 9.1. However, some Apple users are reluctant to use it, because it could damage their devices. Moreover, if a user made a mistake while updating iPhone or iPad to iOS 9.1, they'll be stuck with it because Apple disabled downgrading option.

For Apple subscribers who wants to try the semi-jailbreak tools of Pangu, here are the steps to install it:

First, go to the official website of Pangu semi-jailbreak by using Safari browser. Remember to bookmark the page, in case the jailbreak installation failed, this will restart the installation process automatically.

Press the iOS 9.1 jailbreak button, and then let the website verify your iOs version. When the verification process is done, tap the Continue button and wait for 20 to 40 seconds to complete the process.

After that, you'll be redirected to a website to finish the set-up of the semi-jailbreak tool.

You can use the semi-jailbreak software to download Cydia, the jailbreak app store. It has tons of applications not available in Apple App store.

In a report from Mac Rumors, it says there could be an iOS 9.1 jailbreak software that is already fully-functional. However, the software is not yet available for the public to download.

 A cyber security firm Zerodium launched a $1 million bounty for any hacking team that can jailbreak iOS 9.1. A hacking team reportedly bagged the bounty to access Apple's software. The undisclosed team has allegedly managed to develop a browser-based jailbreak that can work on both beta versions of the iOS 9.1 and iOS 9.2.

However, since Zerodium owns the license for the jailbreaking tool, it is still uncertain whether they will release it to public for free.

While Apple is working hard to put the best digital defense for their its iOS system, the jailbreakers are also doing the same effort to get access to the operating system.
