12.4 Windows — Checkrain

Moreover, iOS 12.4’s compatibility with older tweaks—many never updated for iOS 13—made it a haven for classic jailbreak utilities: Activator , Springtomize 3 , BioProtect , and iFile all ran without issue. As of 2024–2025, checkra1n remains usable, but iOS 12.4 is largely obsolete. Most apps require iOS 13 or later. Apple has stopped signing iOS 12.4 for years, meaning no new devices can downgrade to it. Yet for those who preserved a device on 12.4, checkra1n still works perfectly—provided they have access to a Mac or a Linux boot drive.

The Windows situation has improved slightly: the checkra1n team released an official Linux binary that runs on Windows Subsystem for Linux (WSL2) with USB/IP support, but this remains a niche, technical solution. A true native Windows GUI never arrived. Checkra1n on iOS 12.4 from Windows is a story of adaptation. It demonstrates that even the most elegant jailbreak cannot escape the constraints of platform fragmentation. For the dedicated Windows user, the path existed—not through a double-clickable .exe , but through the willingness to boot an alternative operating system from a USB stick. That friction filtered out casual users, leaving only those committed enough to appreciate the power of a bootrom exploit. Today, iOS 12.4 with checkra1n stands as a museum piece: a snapshot of a time when device freedom was just a Linux reboot away, even from the shores of Windows.
