later prob i facing over is :
1. all the cydia setting missing
2. when try to use SBsetting, the carema will on in the same time
3. some time it will going to safe mood
You could have installed a tweak or app that is conflicting with your phone thats why its going into sfemode. Try hard resetting and finding whatever you installed from Cydia and removing it. Hold sleep wake button and home button until you see the apple logo and release
