SemiRestore7

SemiRestore7 has already proven to me that it does do the job after being stuck in a respring loop and successfully restoring my device whilst keeping my jailbreak. Semi restore is the best way to get a clean copy of your current iOS without losing your Jailbreak. Please mind that this tool can't downgrade your iOS or modem firmware. It's only bring your device back to original state while remain your jailbreak safe.
