Here are some tips to pry the cover off without damaging the digitizer: the cover is cemented with adhesive tape, making it hard to insert a tool into the seam, so heat the edge only first. Once you have it warm (not hot), use all of your fingers on the power button side to pull the plastic edge, using your thumbs to press on the back - do not try to pry or press against the glass side. Also, do not slide the pry tool under the glass and lift up, you can crack the glass. It takes patience
