iOS 12.5.7 represents the end of an era — the final signed firmware for beloved devices that defined Apple’s mid-2010s lineup. Thanks to the permanent checkm8 bootrom exploit, Windows users have multiple reliable methods to jailbreak this version.
For most users, the palera1n + palen1x method is the future-proof choice. It’s actively maintained, supports both rootful and rootless environments, and offers the broadest tweak compatibility.
If you’ve been holding onto your iPhone 5s or iPad Air hoping to customize it beyond Apple’s limitations, now is the time. Follow this guide carefully, respect the prerequisites, and you’ll breathe new life into hardware that Apple left behind.
Happy tweaking, and welcome back to the jailbreak community.

⚠️ Warning: Do not use a virtual machine (VMware/VirtualBox) for this process. USB passthrough often fails with checkm8-based tools. jailbreak ios 12.5.7 windows
While original palera1n was macOS/Linux-only, the community port palen1x allows Windows users to boot a stripped-down Linux environment that runs palera1n flawlessly.
Because Checkra1n runs natively on Linux, and Windows can create a Linux environment, the best solution is to create a bootable USB drive. This allows your computer to temporarily run Linux so you can run Checkra1n.
What you need:
The Steps:
Pros: No virtual machine lag; direct USB access. Cons: Requires restarting your PC and navigating a basic Linux environment.
For a dedicated secondary device or a media consumption tablet, it’s absolutely worth it. For a daily driver with sensitive data — proceed with caution.
If you don't want to restart your computer or create a boot drive, you can run Linux inside Windows using software like VMware or VirtualBox.
The Steps:
Warning: This method can be finicky. DFU mode detection sometimes fails inside Virtual Machines. If the exploit fails, try unplugging and replugging the device or switching USB ports.
