Ok so yesterday I downloaded a tweak from cydia. I have an iPad 4th gen wifi 16gb on iOS 7.0.4. After I downloaded as usual it told me to respring. When it did that I was put into safe mode. I managed to respring it again and after that, it was no longer in safe mode, but worse. None of my tweaks were working (gridlock 2.0, f.lux, and more graphical tweaks) except iFile and certain ones. Safari kept crashing when I try to open it, and so far I found no way to fix this. Anyone who knows how to fix something like this (yes I have removed all tweaks on mobile substrate and it didn't affect anything) please help and tell me. Thanks!
