After editing the build file for a tweak and rebooting my s4, it won't boot. I can get into recovery mode, so I went into safestrap 3.72 and selected restore to restore a backup I made a few days ago. it started fine, but now appears to be stuck for the last hour. the progress bar at the bottom is al lthe way to the end but it is still showing "restoring cache". not sure how long I should wait until I give up on it, and if I forcibly stop it will it mess things up even more?
