So I installed some sort of deb file by sideloading it through ifunbox and now I have an issue where cydia will not update, and will not show anything under my search, or currently installed. I've tried a couple of methods of trying to get it back, but even that rat thing won't show up by installing it outside of cydia. Since it's borked, I decided to try and run the evasi0n program from windows again, but it says "your device is already jailbroken and running it again is NOT recommended". Though it says not recommended, think I can rebuild my jailbreak/cydia by running it again? Other than that, could I do a full system format from the device itself (not using computer)? Or would this force me to connect to computer and update?
