Before you download any "top jailbreak" for iOS 12.5.7, consider these drawbacks:
Your device will reboot. If Sileo is not on your home screen, open Chimera and tap jailbreak again until it succeeds. Method 2: Installing Freya (No-Computer Safari Method)
Most modern jailbreak apps have a built-in "Restore RootFS" option. Tapping this will remove the jailbreak and all installed tweaks, returning your device to a stock state. As a last resort, you can always perform a DFU restore to completely wipe and reinstall iOS.
