Never used safestrap but with bootstrap you open it up, click the top button (can't remember what it is). You should see a little, quick pop-up that says success. Then, you push the bottom button to reboot your phone into CWM...I believe it is. Once there you can make a backup, restore backup, clear....etc. To restore, I believe you first have to navigate (volume buttons) and select (power button) 'backup/restore,' then to backup you'd pick back up. To restore you'd pick restore and then navigate to your previous backup. It seemed pretty self explanatory to me. Any additional questions? Why'd you try to take off bootstrap? Seems to me if you're running it and gtg then there's no real reason to change it...especially if you already backed up your system...
