I think you can send death certificate and ask them to make your dad as primary applicant. Someone else went through this process and was able to change dependent to primary. it will take some time as CIC working with low capacity. Take care !
you can submit your birth or school documents along with any documents your parents have which indicate relationship between your grandmother and your parent -like your father passport or birth certificate
