Before analyzing the keyword, let’s break down the core component: checkra1n.

Checkra1n is a semi-tethered jailbreak based on the checkm8 bootrom exploit. Unlike software-based jailbreaks, checkm8 is a hardware-level vulnerability in Apple’s A5 through A11 chips (iPhone 5s to iPhone X). It cannot be patched with a software update.

As of the publication of this article, checkra1n supports iOS 12 up to iOS 14.8.1 fully. For iOS 15, checkra1n works but with a major caveat: A11 devices (iPhone 8, 8 Plus, X) lose their passcode. You cannot use Face ID or Touch ID if you jailbreak iOS 15 with checkra1n.

Best practice: Only download checkra1n-related tools from the official website (checkra.in) or trusted GitHub repos with thousands of stars and active audits. As of early 2025, the only recommended Windows method is the official checkn1x image (a minimal Linux distro that auto-boots checkra1n).

Unofficial builds are notorious for crashing. They may fail to detect the device in DFU mode or, worse, cause the device to enter a boot loop. The "0124" build suggests it is based on an older version of checkra1n, which may not support the latest iOS versions that the official tool currently supports. Before analyzing the keyword
