‘Not a bypass’ is a global jailbreak detection bypass for palera1n users

Many App Store apps, such as banking apps or games will embed some form of jailbreak detection to prevent jailbreakers from using their apps. If you jailbreak, then calling this problem a thorn in your side might feel like an understatement.

Not a bypass in a package manager app.

Fortunately, iOS developer Uckermark has released a free jailbreak tweak called Not a bypass that, despite the nomenclature, is indeed a jailbreak detection bypass.

According to the /r/jailbreak release post, Not a bypass defeats various jailbreak detection techniques, but like with any jailbreak detection bypass, it’s apparent that it doesn’t defeat all of them.

For example, while the tweak may work in games like Clash of Clans or certain banking apps, it doesn’t work in games like Pokémon GO, which uses a different jailbreak detection entirely.

Not a bypass currently supports the palera1n jailbreak on iOS & iPadOS versions 15.x-16.3, however the developer intends to add support for additional jailbreaks such as unc0ver and checkra1n in the future, which could make it worthwhile of paying attention to if you’re in need of a jailbreak detection bypass. Support for libhooker-based jailbreaks like Odysseyra1n and Taurine may come later on.

XinaA15 users won’t need jailbreak detection bypass, as the built-in lintui feature already offers this functionality.

If you’re interested in giving Not a bypass a try, then you can hit it up for free from Uckermark’s personal repository via your jailbroken device’s package manager app.
