This happened about 15 minutes ago, what I did 3 days ago was installing Quasar, it rebooted and everything was fine. Then tonight when I accidentally compressed a folder into a zip file with ifile, I switched off the iPad by mistake. Then when I switched it on again, it became this. I had to kick the device into safe mode as it does not allow me to access settings and so. I managed to fix it after removing Quasar and using iCleaner to clean all the files. I have absolutely no idea what caused this and I am really curious. Anyone had faced this problem before?
