The term "No PC jailbreak" generally refers to one of two methods, neither of which is currently viable for iOS 12.5.7:
TrollStore (Permanent Install):
Jailbreak Process: The exact process varies depending on the tool. Generally, you'll download the IPA file of the jailbreak tool to your computer (or directly to your iPhone if you have an alternative method), then use a sideloading tool like AltStore or a computer with iTunes to install the IPA file on your device. Once installed, you can launch the jailbreak app on your device and follow its instructions.
If you own a device stuck on iOS 12.5.7, here’s the real jailbreak status:
| Tool | Version Support | Tethered? | PC Required? | |------|----------------|------------|---------------| | Chimera | 12.0 – 12.5.7 | Semi-untethered | Yes (initial sideload) | | unc0ver (last version) | 12.0 – 12.5.7 | Semi-untethered | Yes (initial sideload) | | Checkra1n | 12.0 – 12.5.7 (A7–A11) | Semi-tethered | Yes (Mac/Linux + USB) |
Semi-untethered means: after rebooting, you must re-run the jailbreak app (installed via PC) to regain tweaks.

If you’d like a step-by-step guide using a PC for iOS 12.5.7 (Windows/Mac), I can provide that instead. Let me know.
For users seeking to jailbreak iOS 12.5.7 without a computer in April 2026, the primary working methods involve using signing services or web-based installers to deploy tools like Freya or Chimera directly to the device. Recommended No-PC Methods for iOS 12.5.7
Freya Jailbreak (Direct Install): This is a popular no-PC method for older A7-A9 devices (like the iPhone 5S, 6, and iPad Air).
Open Safari and visit a signed IPA service like ipa-apps.me or applejr.net. Locate Freya and tap "Get" or "Install".
Once the app appears on your home screen, go to Settings > General > Profiles (or VPN & Device Management) and "Trust" the developer profile. The term "No PC jailbreak" generally refers to
Open the Freya app, ensure Airplane Mode is on for better success rates, and tap Jailbreak.
The device will reboot. If Cydia isn't visible, repeat the process until the jailbreak is applied.
Chimera Jailbreak: Chimera supports all devices on iOS 12.0 - 12.5.7.
Similar to Freya, you can attempt to install Chimera via web-based services.
Note that Chimera is semi-untethered, meaning if your device reboots, you must re-open the Chimera app and tap "Enable Jailbreak" to re-activate your tweaks. Important Considerations
Revokes: No-PC methods rely on enterprise certificates. Apple frequently "revokes" these, which may cause the jailbreak app to stop opening or fail to install. If this happens, you must wait for the service to update with a new certificate. TrollStore (Permanent Install):
Alternative for Stability: If web-based methods consistently fail due to revokes, using a computer with tools like Sideloadly or 3uTools is the only "full" and guaranteed way to sideload the jailbreak IPA.
Device Compatibility: These tools are primarily used for legacy devices like the iPhone 5S, 6, 6 Plus, iPad Air, iPad Mini 2, and Mini 3, which are capped at iOS 12.
There is currently no method to jailbreak iOS 12.5.7 without the use of a computer (PC or Mac). The search query "jailbreak ios 1257 no pc full" yields no functional results.
