I have the iFixit repair kit, and want to simply open the front panel to clean some dust that is trapped between the outer glass and the LCD. Is this doable without having to replace the adhesive? If so, how?
You should be able to remove the digitizer if you follow the instructions here. Take your time and be gentle. Don’t lean on the digitizer while you pull, pry and whatnot as that can cause a pressure point. However, regardless of ll the precautions you take, breaking the panel is always a possibility and it’s a risk you have to take. As for the adhesive, ideally you want to remove the old adhesive and apply new one to insure a good bond otherwise more dust will get in.
