Jailbreak iOS 12.1.2 NO Computer with Unc0ver iOS 12

How to Jailbreak iOS 12 - 12.1.2 without a Computer (PC)

The new iOS 12 through iOS 12.1.2 Unc0ver Jailbreak is, as the majority of you know, available for download (here). However to its detriment, the Uncover jailbreak app requires a computer to properly install onto an iPone or iPad. In light of that, in this post-PC world, an overwhelming number of our readers are seeking a “no computer” jailbreak iOS 12 method. Thankfully, you can jailbreak iOS 12 – 12.1.2 without a computer (Mac or PC)!

However while the answer to a computer-less iOS 12 Unc0ver jailbreak is “yes”, there are several caveats that we must outline. First and foremost, a computer is only needed due to how iOS apps are installed (i.e. traditionally strictly through the App Store). To combat this problem, iOS jailbreak developers employe the use of Apple’s self-signing app service. This method allows jailbreakers to run the app on their devices without being a developer (which is the only other app distribution method outside the App Store). This entire process is explained at length in our detailed computer Unc0ver jailbreak iOS 12.1.2 tutorial.

Install Apps without self-signing or App Store

Aside from either self-signing apps with a regular Apple ID (detailed above) or purchasing a $99/year developer account yourself, one bypass/loophole exists. The developer enterprise program allows for apps to be installed sans App Store or computer! These accounts are typically meant for Apple’s enterprise (business) developer partners, including the likes of most Fortune 500 companies.

The developer enterprise solution is important because there are a number of services that try to sign jailbreak apps like Unc0ver for the iOS 12.1.2 jailbreak using said program. This is where things get complicated. Due to the fact that these sites and services are basically re-distributing the application, it’s technically possible for their to bundle their own code with the app! This is where iOS malware becomes theoretically possible.

While we can’t say with 100 percent certainly because we don’t have the source code for the Undecimus .ipa / unc0ver app, Pwn20wnd (therein developer behind the Uncover jailbreak) has acknowledge its distribution through one channel. Said channel is the very source we’re going to use today to install the iOS 12.1.2 jailbreak without a computer. Having said that, proceed with caution! If for any reason you feel like avoiding the no computer on-device method, we ALWAYS recommend using the computer method (click for tutorial).
