[AC Question]

hi i'm not a expert of rom and stuffs but accidentally my little daughter got into the app called rom manager and i guess she made her way to something and when i checked the phone it had something that if you don't know what it mean please deny page.
i guess she has denied all the permissions and now the start and i get multiple errors like ' unfortunately system ui has stopped', 'unfortunately... trebuchet has stopped', cant really go beyond this because when i click ok it just comes back not letting me go anywhere. how do i fix this prob. please help me.
